Solar Switch
Hi All - When I installed my solar setup I put an in-line fuse between the panels and the charge controller, but unfortunately, it's on the roof. Never occurred to me I might want an easy way to shut...

why are some of you going with such big switches? I feel mine is over kill at 30 amps?
And the OP has 130 Watts more and 8 amps more. yeah, I can see going with a 185 amp disconnect.
have had my install for almost four years now,, Picked up the trailer Thursday and installed batteries,switched on the solar. That darn teeny tiny switch worked! Guess in hind sight I should have installed a 36V 250 amp service cut out with that line of thinking!
I do agree that my little switch probably isnt man enough for my system, But at what ratio should I have followed? Everything I looked at in a switch I found with the one I installed, IE: wire size,maximum amperage draw,Interior/exterior,ease of installation etc.
So even if the OP decides to Double his panel size, he is still under 40 amps and still at 12v. Why such a large switch/disconnect? Wouldn't you size it for the intended job?
When I called my solar supplier and asked him for advise, he told me to go to an auto store and pick up a 12v switch and try to get at least something with double the amperage. So in theory, for me a 20 amp 12v switch would work. OP would be looking at like a 40 amp switch??
Or Am I not seeing the big picture here?
