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...

And the OP has 130 Watts more and 8 amps more. yeah, I can see going with a 185 amp disconnect.
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?
He doesn't have 8 amps more, his panels are in series. Nobody recommended a 185amp disconnect. He's not at 12v.
Which large switch are you talking about?
In my particular case, I run 100+ volts, which can arc when switched. I presented what I use, period. I didn't mean the OP must use that big of a switch, I presented it as a choice, not because it's the "correct" size, but because it's a robust, solid, well-built mountable switch that will work when he decides to enlarge his array. Pianotuna also mentioned that. Right-sizing is nice, and minimum, but going a bit more means you can upsize your systems without having to replace everything in them. And, if a switch is used often enough, you want the darn thing to actually be able to switch 100s of times without breaking. So it's not just the electrical rating that counts.
Besides, he asked what we use.
