Multiplus 12/3000/120 Will Not Turn On Unless Plugged into Shore

Multiplus was functioning for about a month.

Now, it won't turn on when switch is turned to "on"

When I plug into shore power, it will switch on but it turns it self on and off randomly and doesn't seem to be charging. Battery won't rise above ~13.6v even when plugged in. Also, smells very hot/melty.


Disconnected everything

checked batteries, both 100ah 12v lithium batteries were ~13.4v

wired just the multiplus, still nothing

double checked all connections connections

measured voltage coming from shore - steady 110v

checked 400 amp fuse between battery and inverter

Any ideas?


Thanks!

@daveeeeee Maybe time to open it up or take it to a dealer to check for you if you smell plastic burning. Do you have a bms?
