We've been customers for 9 years. Some of our Micro-inverters failed and we had a bit of difficulty trying to get this resolved. When I reached the correct person in the organization they went out of their way to make sure that we were satisfied customers. We love being part of green energy solutions for our planet.... read more

There were some bumpy roads with the M-190s. Their M-215 and M-250 product were a marked improvement with failure rates far lower than their prior iteration. Since the IQ line was released failure rates have completely stopped. We have installed over 2,000 installations over the years with nearly every inverter on the market (SMA, Fronius, Solar Edge, Outback, Solis, APS, Enphase, HiQ, Eltek, Solectria, ExcelTech, etc etc etc). Enphase has by far been the most consistent inverter choice with the best value per cost by a long shot. Their tech support used to be poor. In 2018/2019 they revamped their customer support/RMA processes (only know this due to spotty failures of old M-215/M-250 products) and this process has been FAR superior to any other inverter manufacturer on the market. Thank you Enphase for understanding the value in customer support, quality manufacturing, and module level performance optimization.... read more

Enphase wants $400 to transfer their shitty s/w to another owner. My solar system only delivers $20/month of electric credits (FPL), so who in their right mind would pay this price? And the only thing the s/w does is monitor whether their own products are functioning. Then one only needs to read the reviews of the quality of the s/w since they moved the dev/maintenance to india. Conclusion: RIPOFF... read more

I put enphase on the roof in 2012. 12 of 14 inverters failed before they provided the installer with warranty support for the 2 that hadn't failed when replacing 2 that had. The product then was a disaster, and they knew it, but put me through the ringer until all were replaced with a next generation micro inverter. I can't stress how bad it was to work with Enphase and I had to shell out every time to pay the installer to replace the duds. Their service warranty now is the same as it was then. The newer inverters are undoubtedly more reliable, but they will resist any warranty support if needed. Hope nothing goes wrong.... read more
I worked at the largest company in my State for 5 years. We almost always installed Enphase Micro Inverters. I also have had them on my house for about 5 years M215). I have never had a problem. I love them. When I read the negative reviews, most are from the older micro inverters, before the M215. I also noticed a few that had the wrong size micro inverter for the solar panel. If a system is not designed correctly, any inverter can have a problem. I also see that a lot of the Solar Contractors have gone out of business. It would be wise to look for a reputable company that can take care of you for many years. I know we had a couple of calls on the older ones (190's) that got replaced. I bought a house in another State that has a central optimizer system and I have had it shut down 5 times in 1 year.... read more

My system was installed 8 years ago and I've had a 70% failure rate. The first inverter failed a year after they went online. At first this wasn't a big deal, I'd contact enphase and eventually (a month or two later) they'd send me a replacement, I'd swap inverters and send the failed ones back. But then a couple years ago they decided that they would only allow "professional installers" to replace the inverters. It took me 9 months to get a failed inverter replaced. I had two more inverters fail 3 months ago and I can't get any of the installers in my area to even call me back. From reading the complaints online, apparently enphase only pays the installers chump change to service the inverters and for most installers it's not worth their time.
So now you can't get them replaced. A 15-25 year warranty is worthless if you can't get them to honor it.
Enphase is just screwing their customers left and right, I'm surprised their still in business.... read more
I installed my own system comprised of 27 LG330E1C-A5 AC modules which are LG Neon 2 panels factory fitted with Enphase IQ6+ ACM microinverters.

My enphase system is a disaster! 6 weeks after install, I was informed by the middleman company I used that one of my microinvertors is bad. I wondered how that could be possible when I have a monitoring app....
WELL.... it turns out that the free app doesn't tell you much of anything at all....
If you want to know if you have bad parts, you have to pay EXTRA! Oh, and if you want to know if your system is producing more than you're consuming, you have to purchase and install ADDITIONAL components at an extra cost! That sounds completely honest, right?? NO!... read more
I installed my own 20kW 6-string Enphase solar system in 2013. Using M215 and M250 models, I have 87 microinverters, and have yet to have a single problem. It really matters that your installer knows what they are doing. A lot of system problems can be traced back to them. Enphase's M190 and M210 were problem models, but as far as I know, Enphase has an IQ7-based RMA fulfillment which can solve the problem. Solar systems with central string inverters can completely fail, but not with Enphase's solution. Even if a microinverter failure occurs, Enphase's solution will keep on working. It turns a crisis into a problem. Enphase is safer and has better longevity, also.... read more
The owner of 12.5 kw of Panasonic/Sanyo panels, 30 enphase and 20 ABB micro inverters. I only comment on my situation and if you don't believe me I'll give you the login info for ABB and Enphase on my personal sites so you can observe daily for yourself. 6 years and I'm not sure if I've ever strung 2 days together with all my Enphase inverters working at the same time. All the ABB inverters have done is work. Never failed even one time. Now Enphase is trying to lay off responsibility for their product failure on the professional installer. They don't even build repairs for a 6 year old inverter! If my installer wasn't fighting for me "tooth and nail" I'd be in real trouble. Enphase claimed because some of the inverters were moved by the installer to a new home that voided the 25 year warranty, even though nothing like that was ever stated on the contract. Buyer beware, at least that has been my experience.... read more
Be wary of fake reviews. Enphase products are superior and the competition knows this and is scared. Everything about the product is simpler and more efficient from installation to monitoring individual panels to the warranty process. Failure rate is very low. And there is an on/off grid product hitting the market in the first half of 2019. Call lots of installers to get ideas. Don't settle. Best deal is to install yourself.... read more
My installer said Enphase would notify me via email whenever there were any problems with my Enphase Envoy. I was told that Enphase monitors my 42 panels and would immediately notify me of problem. You can forget about even talking to someone at Enphase when problems happen. They kick you back to the installer whose knowledge is limited to installation. They have horrible customer service and refuse to help customers that own their inferior product. Stay away.... read more
Top of the Enphase line at the time of installation. Pros: Individual to each panel; Allows for panel by panel reporting; If 1 panel goes bad, allows others to operate normally; 25 Year Warranty CON: Maximum output capped at 290Watts, even when used with 350-375 Watt or higher rated panels; Not future proofed, as equipment has not kept up with technology & progress. Enphase microinverters should not be behind the power output of solar panels on the market today or in the near future. Enphase should offer products that can maximize the panels offered today and in the near future. Why should I loose 60 Watts in output PER PANEL that my LG-NeonR 350 panels can produce with an inverter clipping output at 290 Watts. Thats 60 Watts x 20 panels for a loss at peak efficiency of about 1,200 Watts in output. (Yes I am aware that there is some minimal loss in converting DC to AC, but not 60 Watts worth per panel.) I was not aware of the clipping until just before my system was installed. With state law regulatory changes, I was under a deadline to have the system installed.... read more
The Enphase inverter seems to be a good match with our LG 350 panels, and was recommended by Southard Solar company for their reliability and efficiency. So far no problems and the entire system is performing even better that we had anticipated!... read more
I had 21 panels installed in 2012 and 8 of the defective M 210 microinverters have failed. The company knows they are defective. My installer (E2 Solar, great company) has replaced 7 of the micro inverters free of charge but now Enphase will no longer reimburse them for the replacement costs. I still have 13 micro inverters which are destined to fail but will have to pay $99.00 per module replaced! another almost $1300.00 over and above the original cost. Yet Enphase claims a 15 year warranty but won't pay to have their defective product replaced. Class action suit in the making.... read more
4 of my 22 panels are no longer working. My installer has gone out of business and Enphase says there is nothing they can do to help me. They cannot help me find a new installer and cannot help me troubleshoot my system. This was a huge investment and is not worth the money.... read more

I can't say that the system has ever reached the 5 KW that it is supposed to.
Great brand approved by one of my closest dear friend who installs solar!
so far my experience with this brand is great.
The monitoring provided by Enphase is great to watch and see when your house is using electricity and when your panels are making electricity for you. I'm also able to see when a panel is having an issue which is a plus (snow covered panel alerts in the monitor so you can clear it off).... read more

Reliable energy production ready for our home or the grid.
I can only go by my experience as an electrician. These are the best out there and will last.

They also seem to be working but can't really say much more on them.
Daily information is always easily read on our computer or cell phone.
My previous installation used a single string inverter. The Enphase micro-inverters seem to be far superior, especially in the area of data. I can tell exactly what each panel is producing. This helps me troubleshoot any output issues such as shading, dirty panel, etc.... read more
Thus far, everything seems to be working quite well.
Can't see them they are under the panels that's why the install looks nice. I don't have a bunch of stuff on the side of my home. I can monitor each panel each inverter from my computer and see my production everyday and every month.... read more

I like that they individually power each panel so that shade on other panels isn't a factor. Also if their is ever an issue I can replace one inverter versus the inverter for the entire system. I also like the monitoring that comes with it.... read more
We expect the microinverters to be as durable as the panels.
The inverters log data on each individual panel and display the data on a nicely designed website. Since each panel gets its own micro-inverter, you would easily be able to tell if there's a problem with one individual panel or inverter.... read more

Bought my M250's in June/2017 for my project, at that time they were on the approved CEC list.
Now here in October/2017, I am trying to get my NEM agreement from SCE and they are no longer on the Approved list. Enphase is not even trying to work with the CEC because they have plans to discontinue
the M250 inverter. So here I sit with $2000 worth of inverters that I cannot use, and will have to spend another $3000 to get some that are approved.... read more
Latest generation of Enphase microinverter. From reading, their powerline signaling now occurs line to line instead of line to neutral which improves the noise performance and scan rate of the inverters by the Envoy. We went with micro-inverters instead of a centralized inverters since we do not have a good place to have a large centralized inverted. An centralized SMA inverter with the ability to have some power during a power failure would be something to think about though but we have a generator to handle grid power failures. We would also need optimizers since we have shading issues during various times of the day.... read more
Again, not being familiar with other brands, all I can say is I have been happy with their performance. As mentioned above, I had one (out of 30) fail. A quick call to Solar Power Pros, and Bill had a replacement unit installed in short order (no charge). Please don't focus on one failure; that can easily happen with any piece of electronic equipment. What I want to point out is the service Solar Power Pros provided in fixing the problem. This is what is nice about a small company; calling directly to the owner, no two week waiting list to have the problem checked out, having two of his installers out right away to take care of the problem.
As for inverters, I would highly recommend going with individual (micro) inverters (rather than one big central inverter). The individual inverters are more efficient, and have a longer life span than a central inverter.... read more
My system, 28 panels, has been in for 7 years now. The first 2-3 years was trouble free. Then the micro inverters started to fail. Enphase is VERY unresponsive and there customer helpline is terrible. On top of that, the Encore system and service I pay for, that is suppose to alert me to problems, does not. I only see a problem if look at my system on line. Not impressed at all. If I was to do it again, I would avoid the micro inverters and/or Enphase... read more

Heard that these are good inverters (at least from the reviews posted on the web).
had a 14.1 kw system installed in May 2011 using Sunpower panels and Enphase micro inverters M120.
the first year produced approx 9,000 kw/h of power, that was for 8 months. and using 6 hours of good sun daily 14 1 kw /hr x 6hrs sun x 240 days = 20,000., my 9,000kw/hr was less than 50/%
2012 , 2013 and 6 months of 2014 the yearly output gets worse and I am embarrassed to show you the numbers..
2015, 2016 and to date in 2017 it would appear that 60% of my ENPHASE MICRO INVERTERS M120 have some some type of failure issue and of the remaining 40% that indicate they are operational ,my production is showing 1kw / hr.
I am about to take action with my installer, who is aware of my issues, and at this point will wait and see what ENPHASE is going to do about my situation.
I roughly estimate that over the 6 yrs of operation I should have produced at a minimum 150,000
my utility meter shows that my total production is 26,000, I will be updating this review after I get feed back from ENPHASE.
FYI my installer has informed me that ENPHASE may or may not pay the labor costs to this warranty claim, I will also keep you posted on the outcome of this issue., you can contact me by e-mail email@example.com... read more
The micro inverters appear to be of high quality are working well.
Being able to get daily updates on each panel is a real plus.
Same sentiments apply as the ones expressed above.
They work well. I am able to follow the amount of output of each panel online. I have one tree that casts a shadow along the bottom row when the sun is low in the winter months. I can watch the shadow move online as the output for each panel dips.... read more
So far, the microinverters are producing 10 watts more than their rated 280VA maximum continuous output power, a welcome surprise. (The inverters have a 290VA peak power output, but they're able to maintain this peak for longer than I expected, i.e., more than 2 hours.)... read more

We can monitor our system production in real time which I think is a very nice feature.
No appliances or systems have failed since the installation 3 months ago.
Again - not my area of expertise - but they work
After researching on the internet these met our needs the best.
As construction professionals, we like this model for it's safety features.
They make it easy to trouble shoot and repair if there is ever a problem
I had Enphase microinverters installed for each of my 27 panels in 2010, after 4 or 5 years the inverters started failing, about 6 - 8 per year. Enphase sent new inverters and solar installer begrudingly installed them while complaining that Enphase didn't reimburse at a level that was worth their while. Now I have another 6 inverters that have gone bad this year and Enphase has told installers that they are no longer reimbursing for labor for inverters older than 2 years! This passes the cost for labor to me -$450 dollars. I am looking into other means of getting them to honor their original agreement.... read more
If you want plug and play, this inverter is the way to go. If you are a geek type and love to see stats and real time numbers, this inverter is not going to show you too much. They have their enlighten website that will show you data for your system, but it cost extra to get the enhanced data to see panel by panel data. This inverter also has NO user changeable settings on it so you get what you get. If the company goes out of business, I don't think you are going to be able to get any data off the inverter / panels anymore unless you have a stand alone energy management / monitoring system like a TED system for example.
To be honest, I would strongly suggest a monitoring system like The Energy Detective as a fine example if you really want to know what your panels / house / overall energy situation is. :
This system is stand alone so even if that company goes out of business, you still have access to your power data. For simplicity though, these inverters are the way to go.... read more
I was told that they are very good inverters and I have no reason to think otherwise.
Micro inverter with 25 year warranty to match the panels
Enphase lied about their warranty. I had my 22 panels with M190 installed mid 2010. One of the M190 failed in April/2017, I've been trying to contact Enphase supports. They kept redirecting me to my installer, who had gone out of business in 2014. Once I told them that, Enphase support ignored all further requests for warranty service.
I don't mind if they just send me a replacement unit. I can find someone to install/replace it for me.
But ignoring a customer and not honoring warranty seem to be bad ethics. I am considering filing complaints with BBB and the Consumer Protection Agency (both local and federal).... read more
I don't have enough knowledge of the product to properly evaluate it.
I love how I can see the performance of my panels online!
Not sure of the model, but they do a great job.
I have enjoyed the system and being able to track production of energy that is being produced.
I have had no problems. They are performing as expected.
It is working very well. The perk energy was generated at 4.4kWh. Overall, I am getting 34kWh a day which is higher than I anticipate. My daily usage is around 28kWh and I am going to get credit for the excessive energy provided by my system.... read more
We have had Enphase microinverters on residential roof PV systems for over 6 years. In our experience, over 10% of the microinverters fail per year! The real world MTBF is magnitudes worse than specified. To make things worse, the monitoring system fails to send email alerts when a microinverter fails, so we have to manually monitor the systems about every 2 weeks. To make things even worse, Enphase support is almost non-existent; the most they will do is mail a replacement module, although it is known that there is a design/manufacturing defect in the model; they take no responsibility for replacement, which involves considerable time and labor on residential roofs. Installers who had used Enphase in the past, won't touch Enphase for new installs; I certainly would not.... read more
Really advanced compared to everyone else and came with a 25 year warranty.
Work great, Happy that each panel has its own inverter.
With the Enphase microinverters we are able to see the production of our system in real-time. We can also see the historical production and the production of each panel. We really love these connectivity features. They work flawlessly, but we don't have to worry about issues because they have a 25 year warranty.... read more
So far so good, I haven't had any problems with the system.
The end phase inverter means that each panel has its own micro inverter, which allows it to function independently. So if one panel is not working or producing for any reason the other panels will continue to provide energy production.... read more
These seem to be working really well and we have enjoyed having them.
Best technology in the industry. Great interface in the app!
Efficiency top rated. Our experience would bear that out.
We used Enphase 215 watts on the earlier house, and M250 on the Canadian Solar panels. We have some shadowing issues on our roof, so micro inverters seemed best. The Envoy -S monitoring system gives us an excellent view into the workings of the system. Between the original 32-inverter system in 2013 and the present 24-inverter system installed in early 2016, we have had zero failures.... read more
Efficient inverter which has given me no problems thus far. I'd recommend the Enphase brand.
If your router password changes, for example if you get a new router, there is no way to update the password on their monitoring system. You get stuck in a perptetual loop of their app telling you to follow instructions that do not exist in the app. Someone should be fired.... read more

I had my system installed six years ago. I immediately started having problems that were most likely due to poor installation and/or grounding. Within the first couple of years, the Internet TP Links let out a puff of smoke and quit working. It was like pulling teeth to get a replacement from Enphase; their customer (lack of) service was abysmal at best.
About a year ago, the system started tripping the circuit breaker. At first it was just occasionally. It continued to worsen until it would trip the circuit breaker within minutes of re-setting it. Finally, one of the inverters failed and that solved the circuit-breaker issue. I've been waiting nearly a month for a replacement inverter; my contractor is slow to respond and claims Enphase is "working on" sending a replacement. In the meantime, another inverter has failed. I wonder how long it will take Enphase to supply a replacement for that one. I fully expect more inverter failures in the future based on the reviews I have read. It seems like many, many people have had multiple failures. It appears the inverters can be expected to have a six-year lifespan or less.
Enphase equipment is unreliable junk. I regret my decision to use their products.... read more
Enphase microinverters are considered the finest in the industy. A trusted name.

I own a 10 panel array with M190 inverters. I have had 4 replaced in 4 years. Another one has gone bad but the contractor that did the installation has gone out of business. Other contractors who install Enphase systems require payment for labor and diagnosis but not the micro-inverter. Yet the Enphase warranty says AT NO COST. This issue is not with the other contractors as they will honor warranties on systems they installed. But the warranty is with Enphase and they are not stepping up to honor it. I caution all potential buyers to go slowly. Try calling Enphase as a system owner and speak to someone. I have been unable to.... read more
With the M250, the DC circuit is isolated and insulated from the ground, so no ground electrode conductor (GEC) is required for the microinverter. A ground fault protection (GFP) is integrated into the microinverter. The M250 microinverter is located under each array of the Suniva solar panels. You can't see any cable lines because everything is run through the attic and out the side of the house to the electrical boxes. These have an "industry-leading warranty", up to 25 years.... read more
So far so good. They have only been turned on for about a month and i have no complaints.
I have a small solar system using 12 enphase microinverters. Seven of the inverters have failed during the 6 years the system has been operational. The 6th inverter failed on Dec. 18, 2016 and the replacement arrived today, Jan. 25, 2017. Ironically, microinverter number 7 failed today, the day replacement number six arrived. Replacing them is a pain, especially since the company that installed the system has been out of business for over 3 years. I have to get another company to replace an inverter when it fails and it is difficult for me as a homeowner to contact enphase as they only seem to want to speak with installers. I email them on their website and get no response. I get tired of having to deal with all the microinverter failures that I have had. If it was easy to contact enphase for a replacement inverter the failures would not be so bad.... read more

So far so good. Monitoring system shows all inverters operational and working as designed.
Only slight challenge with inverters is the signal appears to be weak as I have to share the outlet for my solar hub with that of my cable modem and wireless router.

I love the enphase monitoring system. Its very user friendly and easy to read.
Again, researched inverter, top of the line.
I would have given 0 stars if that was a selection
I like that there is one inverter on every panel, so I get the maximum production from each.
These inverters really help the systems efficiency!
These are excellent, monitoring each panel and updating web data every 15 minutes.
Too soon to tell about the quality of the inverter.
Sorry, cannot remember the model of the inverter. The Enphase system has been great. It allows us to check our production via their ap and it sends us a monthly production email as well. The entire system is Great!... read more
I spent right at 58k before tax incentives for around 12kw of solar. 50 panels. 30 use Enphase micro inverters. Installed 2012-2013.
The balance are all ABB micro inverters. All panels are Panasonic.
All worked well at first. Then the Enphase side just completely fell apart. Enphase won't even talk to me. They have no way to even call them. I have waited months and months for the system to be repaired but no luck. ABB has been better than perfect. Perfect customer support when I have called. Prompt and extremely helpful.
I will never ever purchase another Enphase product. SERVICE SUCKS TO NON EXISTENT.
Appears Enphase has become like so many other "Big" companies. Great till they are paid.
Avoid like the clap.

We had a 30 panel array installed in Athens, GA on Dec 2011. We now have four microinverters to install to replace dead ones. These will make ten microinverters we have had to replace. Enphase does provide replacement microinverters but I have to find someone to replace them. Original installers are in Atlanta and charge quite a premium to drive out and replace. There are local solar companys but it ain't cheap. I'm thinking I may get some financial benefit from this system yet but I doubt it. From all the one star reviews seems like we could mount a class action suit if anyone knows how!... read more
Pacific Palisades, CA
We have been installing Enphase micro inverters for the past five years with 1 failure. we have installed the M215 to the S280. They are the bellwether of the micro-inverter movement and have been a steady work horse for us. We like the fact we get module level monitoring and we don't have to worry about string shut down with shading or a malfunctioning module.
As mentioned, we have had 1 failure in all the time we have installed them and they immediately sent us a replacement and paid us for the service call. We have found them to be a quality product and I'm hopeful their new product line will bring them back to the forefront of the industry.... read more
I have tried to contact Enphase through email and phone with no success. I had replaced a inverter in 2013 and it has failed again. I have the old M190 inverter. I work in the electrical field and know something about solar systems.The inverters are a plug and play. For people that have given enphase five stars they must not have had a problem recently. A couple of years ago I would have give them five stars also.... read more
A couple of weeks ago I received a mass email that was sent out to over
300 people that said, Enphase will no longer support the home owner to fix any problem that may come up. I have sent three email to Enphase because one of my M190 microinverters has stopped communicating with the envoy. I work in the electrical field and know something of what is going on with my solar system.
The microinverters are a plug and play, not complicated. A couple of years ago I would have given Enphase a five star review but now after every thing I have now reviewed I can not. So for the people that have given them a five star review, you have not had a problem recently.... read more
Their software is lousy. There is no way for an customer to call and get help with their poorly-designed monitoring software!
They actively refuse to help homeowners, and seem to think that they can take our money for their product and not be responsible for how well it works or doesn't work!
If I had known this was the kind of 'support' we'd get, I would never have purchased a system using their equipment!
Also, they don't understand the difference between sending a blast email to over 300 people using 'TO' vs 'BCC'!!!... read more
My solar panel installer went out of business 3 years ago and now I am having trouble viewing my panels on line and the installer did not tell me that the monitoring would stop, so I tried to contact Enphase to find out what was wrong.No response from them after repeated emails to them. Then after the last email I got a response of Case Closed and no answer to any of my questions. I guess I will contact other installers to find out who they use for monitoring their panels. At this point I do not know which panels are working and which ones are not. Never again!... read more
I was very happy with my system until it needed its first repair. I have been waiting since June and the communication is terrible along with no action to get the part sent to my local installer. this is very frustrating... read more
These people apparently sell their monitoring systems to contractors, and then will not give technical support or service the monitoring systems once the contractors are finished. If you go on their website there is absolutely no way to contact them except for an e-mail address and the only response you will get is "go see your installer". Well, like many I have found that my installer is no longer in business. Enphase Energy just told me to find another installer to help me. They won't... read more
My array is composed of 16 Canadian Solar panels and 8 D-380 Enphase micro-inverters. The D-380 is a single package of two D-190 inverters.
Over my 5 years of system ownership, I've had a total of 7 inverter failures.
When I now try to contact Enphase, they will not allow me to talk to anyone at their company. My email was replied to by a common email message to 380 customers, saying that Enphase will NO LONGER communicate with their customers. Customers must go through the installer. Many people are complaining that their installers have gone out of business or that they themselves installed their own system.
I'm starting to think that there is something amiss at Enphase? Their stock has plummeted towards being a penny stock.... read more
I had an excellent installer put in 19 panels with m250 inverters. The installation was excellent, in a difficult location in the city. In every way I am very pleased with the installer. I have the technical knowledge and experience in electric and electronic equipment to make this statement. NOTHING wrong with the installer or his installation.
The installer has since cancelled his account with Enphase because of so many failures(they were working just fine for him, then suddenly he had failures all over the place). One "customer service" tech was extremely rude to him over a customer who simply could not get internet service by any method and that was the final straw for the installer.
I am entirely qualified to be a self maintainer. Changing a microinverter is a 5 minute job with my ground mounted rack. Getting the Enphase technician to change the inverter serial number in their monitoring equipment is a huge headache. about 5 days trying to get ahold of them with NO results.
In 4 years 4 inverters failed, 2 this year alone.
Between NO customer support, and a product that fails so often, this is a product no one needs to purchase.
If this fails on your roof, you have to pay a installer to change it out. Yes, the inverter has a 25 year warranty, but you still have to pay a installer to change it out.
Putting electronics out in the weather, particularly in cold climates and on roofs or other expensive to get to locations is the last place you want them. Increased failure rate and expensive to get to in order to replace them.
As long as I can get these inverters replaced by Enphase, I will continue using them. My future plan is to throw them away and go to a central inverter when I can afford it, and am forced to.
Go to the Edison Electric Institute site, and on their documents section look for "disruptivechallenges.pdf". This document describes the absolute intolerance of electric utilities for grid tied solar.
The future of solar electric is NOT grid tied. Which also means that the Enphase microinverter is a dead duck. Look at all the ways utilities are now attacking anything to do with net metering and distributed generation. The above document lays out their manifesto in graphic detail.
Again DO NOT BUY Enphase microinverters. Unreliable, rotten customer service and a product that is already obsolete.... read more
I have 73 Enphase microinverters spread out over 6 solar strings giving me almost 100,000-Watt-hours daily here in the Sunshine State (Florida). I have installed quite a few Enphase systems — at SEI in Paonia, Colorado, with GridAlternatives.org in Colorado, and here in Florida under private contracts. I have never seen an Enphase microinverter failure. Enphase is simple and offers 100% fault-tolerant systems without any 1 single point of failure. Enphase is the superior solution over the older, central string inverter-based solar PV systems.... read more
I have sold over 850 solar systems over ten years. I sold the first gen of Enphase and they worked well, but there were issues occasionally. My company stopped selling them about six years ago. When I see bad reviews, a common theme I read is the installer let them down; not Enphase. Enphase has always supported their products. I now work for a different company who sells/installs the latest Enphase systems and they appear to be bulletproof. My company has installed them for five years without any issues.... read more
We have 44 microinverters part 800-00065-r03(M190) and have had 12 fail within 4 years. Waiting almost 2 months for a replacement during summer. Customer Service is bad, they won't consider a bad lot of inverters until a home experiences a 50% failure rate !!! Why wasn't THAT statement printered in their warrenty.... read more
Our system was installed in late 2011. We have 20 panels originally installed with M190 Enphase inverters. Seven of the M190 inverters have failed. Customer service was originally top notch. Enphase replaced the inverters promptly when problems were reported. More recently, they sent us the replacement inverters and I switched them out. Now, Enphase won't talk to me directly. I have to go through my installer.
The monitoring via Envoy is very nice. I know exactly where the problems are and when they started. The inverters themselves are fairly easy to switch out. But, it's clear that the M190 failure rate is very high. And it seems like Enphase is backing away from their warranty promises.... read more
When I first read of these they sounded like a do-it your self er dream all UL up to the point of termination no single point of failure 95% efficiency 25 year warranty all grate unless its BS, I only have a 21 panel system that I installed my self all done by code even installed a hole house surge protector, the first one failed about two years ago, called they verified the failure and they shipped a new one no problem, now a second one has failed and when you call its a recording stating something along the lines of if your not a pro they don't want to talk to you and then promptly hangs up, there's also an email system but after a week and two emails with no response, there seems to be a problem with the company heading in a downward direction, so if your buying based on 25 year clams and warranty Id keep looking.... read more
45 Market St, Mashpee MA 02649, MA
I purchased a 10 kW ground mount system with no shading issues.
I had 24 - D380's installed in 2011. 8 failed in the first two years. The installed stopped swapping them out after 2 years, despite their 5 year warranty.
Today I have an 11th failed unit, contacted Enphase support over a month ago and have yet to receive a response. I have even had one warranty replacement fail.
There are grid-tie string inverters on the market, some will supply emergency power (as long as the sun is shinning) locally when the grid is down.
I gave them one star only because the site would not accept anything lower !!! :o(... read more
I have had 25 M190 inverters installed since 2011 with 7 failures to date, 2 in the last couple of months. Enphase has now gone to not dealing with the owners, just the installers. Unfortunately my installers went out of business, so I have been doing the replacements myself. The first 5 inverters were replaced within a week of contacting support. I finally received the shipping notification today to replace the last one that failed at the end of March, terrible service now. Another one just failed this week, I wonder how long it will take to replace that!... read more
I've had 15 M190 microinverters fail in the last 5 years. The system was bought from Real Good Solar who changed there name to RGSEnergy and moved to NY from CA two years ago. Since RGS took over customer service has suffered terribly. It takes me a minimum of 5 emails and 1 1/2 months to get RGS to replace the bad M190.
They are in denial that there is a problem with the Enphase M190. Every time I report a failure they tell me this is highly unusual and offer to have a tech examine my solar array. But no examination will show a problem since a device gives no indication its going to fail.
Its a really bad situation and I'm thinking my only recourse is to go to court and get a judge to rule they need to replace my remaining M190s with M215s.... read more
There is no support for these microinverters it is a sham company that has very little reason for being. They have gradually degenerated to zero technical help and refuse to stand behind their product when there are problems.... read more
I have a 9KV 36 panel ground array system using PH 255 Conergy panels and M215 microinverters installed December 2013. I have had 10 of the 36 inverters fail so far (2nd year). Being able to monitor production of each individual panel is great with the Envoy system. Enphase so far has replaced 7 inverters after several months of waiting (partly due to the installer) and has approved replacement of the other three---still waiting on installer a couple months now. These failures were not picked up on the Enlighten software settings. I picked them up myself since I monitor the system regularly. One was a complete failure. The other 9 were producing at a fraction of the fully functioning inverters, usually in the 50-70% range. I have not been able to get an explanation for such a high failure rate.... read more
Over the last five years, 14 of 42 M190 micro inverters have gone bad. Enphase will no longer talk to me, the "customer who purchased directly" despite the fact that the Warranty terms provide for replacement specifically from the CUSTOMER! Buying these micro inverters was the biggest mistake I have ever made in terms of investment. Enphase should recall all of these turkeys and provide replacements that are reliable.... read more
SPARTANBURG , SC
I had mine installed 2 years ago, called Enphase they will not talk to customer only Installer he tells me nothing he can do
The only way to monitor our Enphase microinverters is an Envoy box. Our box stopped working after 2 years. We found out it only has a 1 year warranty. New box costs $500. Nice scam to charge $500/ 2 years (if you are lucky) to monitor output of microinverters with a 25 year warranty. If you can't monitor, you can't prove they are defective. Would never recommend this company or it's unreliable products.... read more
I installed 45 inverters on my home installation Dec 2010, Have replaced 14 in 5 years. Enphase now have changed their policy and won't pay the labor to replace any more inverters and no longer wants to deal with the customers, only installers, Gee, Make pay to install, then make me pay to replace their defects. Win, win for them. I know I am not the only one having problems with Enphase. If I could find other Enphase customers who are having similar problems maybe we could somehow force Enphase to listen.... read more
I had 18 panels with the M190 microinverters installed in January 2010 in our vacation home in Berkeley Springs, West Virginia. Beginning in October 2014 one of the inverters began clipping at 140W instead of the nominal 190 W. The second had the same problem beginning in April 2015. In September 2015, the third one failed in the same way and in October 2015 the fourth one started clipping at 140W. With this failure rate, I am surprised that there have not been more reports of the problem. To date I have not had any response from Enphase.

I have had nothing but problems with the M190's and just in the past year have experienced a 10% failure rate on a large residential array. Although Enphase does honor its warranty it takes forever to get the replacement parts. The latest Enphase microinverters may be reliable but the M190 is proving to be a lemon. Enphase either has to increase their support of these units so that failures are addressed and corrected in a timely and efficient manner or withdraw them from the market and replace with a more reliable unit.... read more
These microinverters are a reliability time bomb - or more accurately, a bunch of time bombs on your roof waiting to go off. No way will they last the 25 years Enphase claims they will. I just serviced a customer that had a 33 panel system installed 5 years ago (by a now defunct installer). So far this system has had 22 microinverters conk out. Oh but, he could tell right away that they failed... Give me a break - can we just be satisfied with a really reliable inverter and forget the band aids?... read more
We've a 4.7 kW system made up of 20 235w panels with M215 microinverters and went active in June 2011.
One of the microinverters failed and our installer, SwitchtoSolarnow, received a replacement from Enphase and swapped it right out.
A second microinverters is starting to fail and Switch already contacted Enphase for a replacement.
In both cased I was monitoring and called attention to the problem. No idea if Enphase would have noticed but once they knew, there were no problems getting the replacement.... read more

I run a small solar installer company, and until I used Enphase, the installation and maintenance process was much more complicated. Before understanding the whole micro inverter, Envoy, Enlighten relationship, I did not really know Enphase, but after using their products for 4 years now, I would never switch back to a central inverter or any 'dumb' micro inverter because it is cheaper in cost. Troubleshooting a solar PV installation issue is super-easy with Enphase, but not with other competitor products. Many installers are patiently awaiting the AC battery in 2016, for it will open the NetMetering strategy to a much wider audience, allowing for more customers to get onto the solar bandwagon. I believe that by increasing their O&M business through their purchase of NextPhase and their entry into the battery business, Enphase will diversify enough to increase their bottom line and overall company value. Having Eliiy from Japan and Midnight Solar as partners assisting them with this AC battery venture makes me very confident that Enphase will roll out a great product. I am hoping that the AC battery will take a bite out of the low-end fossil fuel-based generators and allow people to run their lights, refrigerators, freezers and other critical electrical devices during a grid outage. The AC battery has been part of Enphase Energy's core concept since day #1, hence the name 'Energy' and not 'Solar'; their long range goal is to be a serious energy company and not just a solar component provider company. Furthermore, if you look at the loyal customer base they have built selling their M-250, M-215 and other micro inverter products, then you can surmise that those customers might be willing to jump on the AC battery bandwagon if the price is right. I know a number of my customers, including myself, who are anxiously awaiting Enphase's AC battery product. I am long on Enphase, and believe they are truly the Apple of the micro inverter market.... read more

The biggest advantage of Enphase is problem identification and isolation. My system of 34 panels and microinverters has been up for three years. Unfortunately, the company that made my panels, and the one that installed them, went out of business.
I have had four microinverters go bad in the three years that I have had my system. Three in the period of about a month and the fourth a few months later about a year ago. They are under warranty. The technicians at Enphase and I discussed the situation and they told me what had to be checked. I had another local company check the first three, I notified Enphase, and they sent out repacements. The local company then installed the replacements. I replaced the fourth one myself to save some money. During that time the other panels and microinverters still worked fine.
With microinverters, I basically have 34 individual PV systems. If my system had only one inverter, the entire system would have been down if the inverter went down. In my case, I lose 1/34 of my output if I lose one microinverter or one panel.
I currently have one panel that is only putting out about 2/3 the amount of power that it should. If this was a conventional system, it would have degraded, or dropped, the entire system. Then I would have had to troubleshoot the entire string to determine which panel was bad. With microinverters, I have the ability to see which panel / microinverter combination has a problem. The only physical troubleshooting necessary was to swap that panel with another panel to verify if the problem was the panel or the microinverter.
Having microinverters on your system instead of one inverter is like having gauges on your car, so that you can determine WHAT is wrong, as opposed to an idiot light that will just tell you that "something" is wrong.
Enphase does not make panels or install systems. If you have a problem with a panel, the installation or your installation company, don't blame Enphase. Enphase's monitoring unit, the Envoy, receives the microinverter communications signals via the power lines. They recommend that it be as close to your power panel as possible. It "CAN" work farther away, but that depends on your location. If you don't have an outlet close enough to your panel that you can spare... you can always install another one.... read more
We have Enphase inverters on our house that were professionally installed 3 years ago. The connectors used by Enphase began getting brittle and falling open. Enphase says it's environmental issue and offered 00000000 support. On top of that the higher support rep was the type of person I can't describe in this post. I would NEVER DO BUSINESS WITH THIS COMPANY!!!!... read more

Paid $23,000 for 18 panels in Jul 2011. I will never see that in recovery costs. Since 2012 I have never had 18 panels working. Thus far 8 panels have failed Solar Universe, the contractor, only makes matters worse by refusing to repair inop panels. My entire solar panel experience has been nothing but a series of lies. I asked Enphase for help and was referred to Solar Universe.
There has to be a good Solar Panel company out there somewhere. This is not it! Richard... read more
There a dozens of inverters on the market and each one has a niche. Some play price, others play voltage ranges, other play temperature ranges. Each one serves a purpose for each individual customer. Enphase plays the design flexibility aspect very well. We use Enphase for customers who either don't need a large system where a string inverter would be ideal, or systems with broken arrays facing multiple directions. They are safe to work with because the energy is inverted at the array (DC to AC). They have an excellent warranty and dealing with their customer service is a breeze. Becuase they use powerline communications, sometimes communication and transmitting data from the array to the internet is problematic, but solveable nonetheless. Great product overall.... read more
This is a pretty cool concept when it works. This is the device that allows the owner to see system performance on the internet. However, the Enphase setup is pretty lame. You have to find an outlet somewhere in your home (the closer to the modem the better) that will be DEDICATED to the power line adapter that the Enphase unit is plugged into. Nothing else is supposed to be plugged into this outlet, including the modem or router. You cannot use a power strip either, otherwise the signal it gets from the panels will be degraded to the point it won't work. I tried four different outlets before I could get a reasonably good signal (3 out of 5 which is the minimum workable).
What you have is a pair of power line adapters. One plugs into a socket that is close enough to the modem to run an Ethernet cable from the adapter to the modem. The other adapter must be plugged into a dedicated outlet as described above, then the Enphase is connected to that via Ethernet cable and plugged into the outlet. The adapters allow the Ethernet signal to run on the electrical wires.
What I find flakey about this is the Enphase ends up in a random area. Mine is in the garage, plugged into an outlet I would rather be able to use for other things.
It has been my experience already that this is not that reliable of an arrangement. I had a hell of a time getting it to work the first time. Now it is not working again. It has been installed for not quite three weeks. This is not a good start.
For the amount invested in this system ($70K+)I can't help but think this should have been installed in a more professional matter. Instead of running all over the house, hoping to find a good enough dedicated outlet. My Enphase is stuck somewhere random and running (or not) in an unreliable way.... read more
We have a 5.5kw system using Enphase M215 inverters. This made the solar system extremely reliable and easy to install, and the Enphase internet access is awesome. I use my iPhone to look at the panels and check on my daily, monthly, and yearly production output. Of course, the separate power meter and combo meter from the power company is great, but when you just want to see how things are going, the Enphase wireless access is really cool. I plan to add some more panels at some point, and will continue with the same products. Two thumbs up!... read more
Tom Norrell, my solar provider and installer, indicated that I would achieve superior performance from my solar panel design. Indeed, they have performed better than expected, and my house is now a "Net-Zero" house, with buy-back of excess energy from local city-provided electric utility. The inverters are monitored by the manufacture, who provides me a monthly report on production, in addition to that provided by utility electric bill.... read more
I would go with Enphase every time. We installed the M215s when the first came out and they have been a really good match for my panels. They just work, no problems with them at all. Plus the monitoring is quite nice.

They have been operating fine. No problem as of 9/25/2013.
We can monitor the output of every individual panel at any given time. Very cool.
Model is M210 (not certain about suffix). Given how snow kept some panels covered longer than others, I was happy that I had micro-inverters.

I think the inverters are all working fine. I get email alerts about every other day that at least one panel is not generating any power even on sunny days.
