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. Apparently having other electronics plugged into the solar hub's outlet reduces the signal strength - but it doesn't appear to be a problem for reading energy production.... read more
So far so good. They have only been turned on for about a month and i have no complaints.
Efficient inverter which has given me no problems thus far. I'd recommend the Enphase brand.
Efficiency top rated. Our experience would bear that out.
These seem to be working really well and we have enjoyed having them.
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
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
As construction professionals, we like this model for it's safety features.
Again - not my area of expertise - but they work
We can monitor our system production in real time which I think is a very nice feature.
Heard that these are good inverters (at least from the reviews posted on the web).
