Problem Fixed

We had two microinverters that weren't reporting so we contacted Enphase to send a technician out to check into them. The technician arrived when they said he would and was able to repair the problem immediately. Very professional and communicated the issue. We will use them again and again. Thank you!

Great job!

The Enphase Customer Service Representative went above and beyond in assisting me. He was very knowledgeable, responsive, thoughtful and had all the answers to fulfill my request. It is a pleasure doing business with your company.

Inverter Failure Rate is wild

I've had a 19 panel system on my roof since 2011. Currently 8 of the original MIs (M190) are still on the roof and only 2 are functional without error messages. Only one other MI (M190IG) reports online - making my system about 80% dead weight. Enphase will replace the inverters, but no one covers the labor anymore - so what's the point? Total junk.

They apparently have ONE technician to solve issues for the whole of midwest

It is not clear why the company has very little resources to handle services. I have tried multiple times to call them, but it is difficult to get some one on the phone. Earliest service availability is more than a month because there is only ONE technician available for the whole of the midwest who only comes out once a month. I am still waiting for some one to come a fix an inverter that has stopped working for months.

Are all Enphase solar and battery systems as dysfuntional as mine?

My system was installed a year ago, and it worked fine up until February when I noticed that the batteries (2 of) were not charging evenly or charging to the settings I had set. This progressively got worst, so what started as a minor difference started to get more extream, resulting in a "BMU Low voltage warning". I reported a problem and after a couple of weeks of complete inaction, I discovered that Enphase had cancelled the problem ticket, because they had not found any error. They didnt look very hard because I sent them screen prints, and I still had the problem. Enphase tried to open a new ticket for the problem, but I insisted that they reopen my initial ticket which they did. My batteries still do not charge evenly, or to the settings I have set, and have on occasion, failed to charge altogether. Enphase are still trying to resolve the issues I reported months ago, and to make matters worse, I have now been told not to use Power Match functionality because it exaserbates the problems, and today I noticed that the battery charging settings for my system have been changed, but not by me. Enphase are insisting that these are firmware problems and should be resolved with new releases (still months away). It like I have been sold a prototype system, to help Enphase develop something that may work correctly at some point in the future. I have solar with enphase inverters, an envoy gateway, and 2 x 5P batteries. If my problems are because of firmware, every similar system to mine must be experiencing the same problems right now? I am currently using the HIES arbitration service, UK trading standards, etc, to get my money back from Bliss Eco Energy (installers) to obtain a solution that actually works as it should. My advice. Avoid.
