Funny, I just looked at a whole series of pictures of your system showing rather detailed diagnosis was done and your claim they pulled out is just not true.
Like yours, mine didn't stop making power, they just stopped reporting it. So in the most important aspect, converting the output of the solar panels to electricity, they have continued to function.
I'm a bit annoyed with these AP Systems microinverters as well but STI's response has been prompt, thorough and a great deal better than is usual in this country. They didn't make these units, I believe they've done their best to verify reliability (which hasn't been fully realized) and they are doing their best to compensate for it and stand behind their installs.
I suspect they've spent most if not all of the profit they made on my original system providing backup for my microinverter problems.
Putting it bluntly, I think your claims and accusations are excessive. In any case, they have been addressed directly by STI so do not repeat them further here. This last bit is why I posted this as Mod 2 rather than Mainecoons.
