This time I used the inverter cut off switch, shut off the water heater and pump. Same thing. Dead. 3rd night. Monitored the batteries charging using the Victron app to confirm 100% charged. Shut off everything except the fridge. Same thing. I did notice that the app showed a 7 amp draw at the time I went to bed. Returned home today and batteries are full. shut off everything, no shore power and no fridge. Still showed a 2.5 amp draw. Going to assess tomorrow. I may have allowed the batteries to go below threshold too many times. I might be upgrading to lithium....
I would appreciate input from anyone that has substantial knowledge of the Victron shunt and solar app. Not 100% sure what I'm looking for. Thanks in advance!

What is the size of your battery bank? Your draw with everything off seems a little high but not way out of line.

Battery was at 95% charge with everything off this morning. I'll turn on the fridge tonight and check tomorrow.

Tony,

Assuming they are 100 ah batteries that give you 200 ah of which 100 is useable. They should run for 10 hours at a 10 amp draw.

The rig has been off grid and sitting all day. Batteries at 98% charged in the rain. Less then an amp draw. Humm tomorrow I'll turn on the fridge and recheck.
