Recs for Solar Cut Off Switch?
Looking for help finding some sort of cut off switch that I can mount on the wall inside my coach next to where the charge controller is currently mounted. Side note: I'm pretty much hemmed into p...

Ok, so which is the higher potential????
Follow the PV array-to-Controller circuit and the Controller-to-Batteries circuit through the 4 breakers.
Thanks! OK, so the MNEPV-15s have their double pos such that the panels are higher than the controller, and the controller is higher than the batteries.
This would support the panels as a current source to charge the batteries, with the panels having a higher voltage than the batteries.
I don't understand the arrows on the controller drawing, where pos and neg are pointing the same way. What are the circuits here?
EDIT--the battery cell while being charged, has electrons flowing through an external circuit to the battery's negative plate from the positive plate. (Reversed for when being discharged)
So you put the pos to pos and the neg to neg with the charger (panel)and battery, and you have the charger being discharged (neg to pos) and the battery being charged (pos to neg)
