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...

So if it is all about the voltage for the amps rating within the watts limit, then:
2700w/12 = 225 amps rating, but in the RV at 14.8v, it is 2700/14.8 = 182 amps?
On polarity "direction" I don't see the way that is marked on a switch, so how to get it right way around if on the battery neg wire or pos wire? Would want an arrow toward the battery (or solar panel) positive post in the States (or negative post in Canada?)
With the solar controller in the middle and the array as the "current source", which way is "positive"? You have the battery circuit direction and the array circuit direction, but the PWM controller passes the battery voltage to the array. How can it do that if they are in opposite directions?
