I have a 3000w multiplus 120v, cerbo gx, 3x100ah lithium battery, 4/0 wire and a bmv712 battery monitor.
When I plug it to Shore power it ramdomly shutdown even with small load (less than 500w) and then restart by it self. Limit curent set to 30amp on 30amp outlet. It tried an other 15amp plug curent Limit set to 15amp or 10amp. No difference. Shutdown often.
Battery full, 20deg C, well ventilated area. All connections tight.
It works fine on battery inverter mode(no Shore power)
Charger only mode no shutdown at all.
Any idea? Thanks
