How would you make a "dump circuit"?
I don't use much power from my system either and most of the time my cc indicates over current. I'm looking for a way to automatically divert power from the panel to a separate circuit to run a ventilation fan to cool down the house.
My idea is for the fan to run only when my batteries are full. I would use the fan to circulate cool air from the basement without draining the batteries. If it's cloudy out the fan would not run but the house would not heat up as much either so it wouldn't be needed.
