When the grid fails and the SOC is on 89% the inverter switches off. I am using average 600W from the system when the grid is off and seldomly get more than 100 minutes from the system before it disconnects. I have tried all the different ESS settings, but it does not seem to have an affect. Still stops at about 90% SOC.
I have disconnected the batteries and tested them individually. Does not seems as if one is faulty. Am I missing something? Is this normal?
