My inverter is shutting down when the battery is fully charged (98%+) and the GX display shows "ESS 3" above the battery.
I have a Multiplus II inverter, a Smart Solar MPPT, a Cerbo GX, and a 100AH 48V battery with CAN-bus BMS communication (Trophy Battery). This is an offgrid system with no ESS assistants programmed. Everything was working fine until my battery reached full charge today and then it started shutting down my inverter repeatedly.
I have the battery controlling the charging with DVCC settings in the Cerbo. Is there some reason the battery would tell the inverter to shut down when it is fully charged? The inverter is only seeing 50-100W load so it is not being overloaded.
I'm happy to provide more info but don't know what is needed at this point so let me know. Thanks
