Multiplus 2 Overload L1 Alarm - but nothing plugged in

I have a MultiPlus II in my Camper Van an i had it "on" to uncharge my battery a little over night an solar then charge it again over day.


I replaced my VE.Bus BMS with the V.2 model last week (could not get it completely to work, by now) to control the mode of the multi from remote.

Just some days later I got a "Overload L1 Alarm" over VRM. But the Multi is not connected to Shore power and nothing no device is using power from the Multi.

I restarted VE.Bus over the Cerbo and then also disconnect and reconnected everything from the batterie, but the alarm is still there.


Has anyone an idea what to do?

Warning or Alarm?

Nothing connected? Often a fridge/compressor or pump can trigger a warning due to high starting amps. The warning can be suppressed via settings.

Check cabling Warning should clear after 20 sec but can be acknowledged via console etc.

Could a refresh of the firmware help?

Could it cause damage to the multi to reload firmware while the error is still there?
