My Multiplus Compact 1600vA does not charge or invert anymore. It used to work fine until I gave it a large current to digest (2kw, I know it only handles 1.2 kw). When I gave it this large current, the shore power was not connected, I had 13.5V in my 400Ah Lifepo4's. As expected I saw the alarm light blinking and within 15 seconds the inverter shut down. After this, the inverter only showed signs of life (passing shore power through) when I plugged in the shore power. I tried and checked some things and eventually decided to delete the Ve.bus bms assistant in Ve.config, to reset it. After this, the inverter doesn't want to turn on anymore. It only shows life when I connect the AC in. For 1 second all three LED's turn on (inverter, charger and alarm LED).
Multiplus compact 1600vA
Ve.bus bms with the mains detector (already tried it without the mains detector in between, no results)
Victron 400Ah Lifepo4
What I tried:
1. I checked all my fuses. Cables to the multiplus read 13V+
2. Disconnected AC in and AC out.
3. Check the VE.Config, charging mode is enabled. Ac input current is 16A
4. Delete VE.Bus bms assistant in VE.Config.
What could it be?
