All their rates have to be approved but the give big money to everyone in the Gov and they get a good return on their investment. I guess that is why they keep doing it.
I have not had any issues with my Enphase 215 microinverters but a solar installer sold new unused extra one on ebay. It was a decent deal so I picked up an extra one. I have 54 microinverters one will go bad at some point. They have a 25 year warranty but it will take some time to get a replacement. So now if one goes bad I can just swap it out with the spare microinverter.
