As stated above what’s going on? Before yesterday, there would be positive charging going into the house bank when returning to my marina slip, replacing amp hrs that had beenused while anchored. Only a 115w discharge while motoring back to the slip this day. The monitor showed 52%.
Back at the slip on shore power, charging the house bank progressed normaly as expected. The house bank charged to 100% overnight.

Today, as soon as I disconnected shore power, even with the house main switch off the the house breaker off a -7.5amp hr rate showed on the Victron house bank monitor. I believe the dc to dc charger was also running as I could hear the fan running. It was showing FUL.
I need help!

If the batteries are full, there's no place to put the power, so solar and engine charging won't register as the DC to DC charger and solar can't charge to a full battery.
 
Thanks for your reply.
My house bank was needing charged after running ac and the electric grill. I expected running the outboard back to the slip with ac and grill off. Still showing no charging and even a negative discharge! I’ve previously enjoyed significant positive charging en route back to the slip. Shore power then resulted in the expected positive charging.
 
After waiting a few days for suggestions to remedy my problem, I disconnected the negative side of my house bank overnight. The following day reconnection yielded a cure for the solar side recharging! I’ve yet to relaunch to discover if my engine now shows charging but am confident it will.
Hoping the problem doesn’t reoccur.
