Poor service, incomplete installation

Had a Generac pwrcell system installed with battery's March of 2022. Everything was fine until September when we had a power outage and the main inverter failed. Took over a month to get someone out to look at it and longer to get it fixed. I asked for the pv map and they installed 6 strings on 2 inverters for a total of 10.8kw. Completely unnecessary considering that each inverter can handle 15kw of pv power. This is where the incomplete installation comes in. Only 5 strings were ever working at any one point. When they removed the Snaprs they connected to a different pv optimizer and it finally showed up on the Dashboard view but the other one that was previously connected shows that it's deactivated. Their technician seems to be hung up on my utility voltage being 252v saying it's too high. However, I have one inverter that has never failed plus the installation manual says the inverters can go up to 260v. They clearly don't know the product they were selling and then never finished installation or did any timely repairs. I just made my 1st payment on this system and it's only worked properly for 6 months. If I could go back I'd avoid this company.
