Need help for powering skoolie
So I bought a partial conversion. 40 ft Thompson. The guy I bought it from has sureline set up, going into 2 12v marine batteries. From there into a 4000 watt inverter(I believe this goes into the outlets for fridge, chargers, etc). Then a separate battery bank runs the water pump(dc) etc...
So I may be completely ignorant, I’m a new Skoolie guy, but when I plugged in my sureline, I assumed I could just run my outlets off of my buddies house power. But, the battery monitor kept tripping to a fault protector saying the batteries were low. Is this because the sureline May only be set up to charge the batteries?
If so what is a good solution to fix this?
(E.g. sureline straight to the outlets, or more batteries?)
What have you guys done for power systems?
In my head I was hoping to have a sureline set up so I can plug into outside power sources when available.
And solar power set up going into a battery bank for boondocking. Is this unrealistic?
