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

Same complaint as Plumley Farms. Very expensive 133 panel/microinverter installation by Astrum. The Enphase m190's installed are not reliable; its been a constant drip, drip, drip of failures. I have to constantly monitor my array. Emails to customer service are seldom answered. It can be months before replacements are installed (currently have one microinverter which have been down since mid September and another since mid October PLUS I now have at least one additional microinverter which is severely under producing). Not counting these current three microinverters which are currently having issues I have had to have at least 10 replaced in the past year. Needless to say at the moment I am not happy and would not recommend.
Unhappy in Derwood. Follow-up to my post of 11/17/2015. Promises but nada. Still waiting for replacements on units which failed back in September. High failure rates on the M190 microinverters used on my system. No responses to emails.... read more
