Enphase
My biggest complaint is that they charge $2 per inverter per year to see the output of the inverters. I have 21 inverters, so $42 per year, and the system only generates $500 per year in electricity per year. Thats almost 10% per year just to see the output.
I tried to search their web site to find out what they charge before I bought the things, but they had no info on what they charge. It was only until after I had installed the inverters that Enphase called me to register the inverter interface, and only after I asked what they charge did I get an answer. Unfortunately, with these inverters installed under the panels on my 2 story house, it would be very difficult to change inverter manufactures. So now if I want to know the output, I have to pay them $42 per year!
If I had known this I would not have bought this product!
