Multiplus Compact 12/1600/70-16 goes in Alarm when connected to shore

Hello! :)

Hopefully you guys can help me up with the trouble shooting / config of my system.

It goes like this:

Shore -> multiplus -> 12V LIONTRON Lifepo

Also I am using a Smart shunt and a cerbo GX via VE.Bus. Firmware is 430.


The system is working fine, until I plug in the shore cable. Then the system shows the red alarm light an the following messages on the cerbo display.

Alarm - temperature high

Alarm - error temperature sensor

Alarm - battery low

The voltage is 13.11V, temp 29 C

When connecting the shore line, the voltage drops to 8.07V DC.

AC-line shows 95V due to the connected generator. Also it shows -1.3A, which I don’t understand.


Could you guys please put me on the right direction to solve the issue?

Thanks!

Are you using galvanic isolation (transformer) for your shore connection?

CCE - Breaker circuit - easyplus (multiplus with breakers)

No additional isolation other than the built in in the easyplus
