I just got of the phone a couple times with my installer contact. And because of the great info folks were able to post here, I was ready.
Meaning, when he told me the lead engineer and COO both looked at my setup and said I had to get a third inverter, and I needed to trust them,
I just said but, and gave all the stuff I got off here. So, I asked him to get in writing what the issue is. He then called back 10 minutes, later, after talking to
the installation supervisor who has been to my job, and said yep, what I have said is totally right and adding like 50 more panels is no big deal and no extra
inverter is needed since he knew I have put in another 11.4K SE to be ready for this. Always ask the 7 but why
I then said great, now I would expect the price for the new panels would be much cheaper since the inverter and all the wiring is already done.. He is now going to get a new quote written up. I then said but will PGE approve adding this. I just sent him my last PGE bill for the info. I guess it is up to them if then can work magic since no way would my last year support any size increase. If so, great, I can save a LOT of money.
