Weird battery power problem
Hi all. I have a 2012 Arctic Fox 1150 with two group 29 batteries. Also have a 240 w solar panel. Have always had weird problems, like not being able to run all 4 jacks at the same time - a relay (or ...

Jacks use significant amps which in turn lowers the battery voltage when they are used when dry camping (should not be a issue with gen or shore power). Lower voltage adds more stress to motors and they run slower. So it's possible that the smaller auto reset breaker is intentional to limit you to 2 jacks at the same time. It could also be related to the wire size to the jacks which could be to small to allow 4 jacks to operate at the same time.
Plus after a night of dry camping the battery voltage is lower in the morning.
I would starting with a fully charged battery (12.7V), shore and solar off, measure the voltage as 2 jacks are lifting the camper. At that point get a good AF technical person to discuss your situation.
For example let's say you measure 11.7V with the jacks lifting. Then if the battery was 50% SOC (12.1V) then you would expect about 11.1V with 2 jacks. With 4 jacks lifting the voltage would be even lower.
