My Multiplus suddenly stopped charging the battery while connected to shore. VRM says ‘fault’, but I can’t find any more details than that. I tried to turn off the inverter and then start it again. It briefly switches on, goes to ‘bulk’ for a second and then switches off again. This pattern repeats 3 times and then the inverter goes to ‘fault’ state.
I checked shore quality. input voltage is 124.4V and frequency is 60.3Hz All that looks normal . Ve.bus doesn’t show an error. No error notifications and nothing in the logs .
How can I troubleshoot this further?
