We were at a festival in the camper the other night and was woken up to over voltage alarms, electrics going haywire. The 12v System had become 16v with Multiplus 12/1600/70-16
Multiplus was connected to the onsite hook-up - generator based. Unplugged the mains and everything returned to normal. I haven't connected to grid/shore again yet as I'm trying to identify likely cause or if fault with the Multiplus before I re-connect. Has anyone else experienced such events?
