Hi Chris I have had a similar experience. This was an off-grid home, built in 2003, the generator a Honda construction generator rated 6.5 kW. The batteries were Rolls 350 AH, 6-volt, L-16. The inverter Outback FX3024. The batteries lasted only 7 years, then replaced with a second set similar Rolls, they lasted only 7 years. ( I believe the short life was due to the insulated battery box) Shortly after the third set of batteries were installed the inverter started to "kick off" the mate said it shut down (disconnected on overvoltage). I replaced with a new FX3024, exactly the same overvoltage. The generator had not done this for it first 14 years of service. I put a load electric heater on for ballast, the same overvoltage occurred. My peak hold voltmeter said it was hitting 176 volts. This is connected to one 120 volt receptacle on the generator. I then concluded it was the generator AVR that was causing the problem because with only the milkhouse 1500 watt heater connected the Generator would voltage spike.
