I saw the fault "high ac input voltage" at least three times. I changed out the boards in the inverter TWICE, both times freebies from OutBack. I checked battery spec. grav., programmed it and re-programmed it, talked ad nauseum on the phone with tech support....nothing. It was OutBack tech support who originally suggested grid problems. The utility sent out a tech and they put a data logger on for a week. When they took it back I never heard from them until I called and said that I was sure it was the transformer as I had eliminated, twice, every possible possibility. My transformer was from the early 70's. Even today, a rainy day, I made 6.2 kwh, just about what I use in a typical day.
