My new 1500 w solar system with 200ah Lifep04 batteries and 3000w inverter using an ATS tapping into grid power when the battery runs low, was working fine for about 5 days. Then early the other morning I suspect right after the ATS switched back to using the inverter, my wife put a large draw on the system and it failed. Specifically the inverter went into Overload and started beeping. It's fried as far as I can tell. It turns on but goes into OL everytime - but that is not my question. The strange thing was at the time the system failed and after I turned the inverter off - the ATS display indicated that it was using the batteries to power the load (the HVSW value was met) when the inverter was off when in actuality the load was being powered by grid power! This I couldn't understand. I'm getting a new inverter but I'm afraid to connect back up to the ATS - any suggestions? If the inverter is off when the ATS hits the HVSW would it know this and continue to supply power from the grid?
