Jeeze 2oldman settle down!
Ok, my mistake, 24 volts, puts him in a little different bracket.
In other responses it was referd to the OP as running 18-20 Amps thru those panels, but I am not sure if that is in series?
So when I referd to the 8 amps more, I meant 8 amps more than my 10 amps (comparing OP to My self 10+8 being 18).
A large Battery cut off switch as apposed to a properly rated rocker switch is what I am referring to as a Large switch!
Yeah I can see the need for a robust Switch/ cutout as yours, But OP is not running 800 watts at 100 volts! Either am I. As you stated he's probably only gonna get 250 watts@24V, A step up is always better but he asked for what is appropriate for his set up?
So I am sorry if ME with a small 200 watt system throwing in my 2cents on an appropriate SWITCH from panel to CC didn't meet your specs, But we are not in your league!
Maybe re read his question? HE already has an In line fuse set up, all he needs is a simple switch before CC!
So what is appropriate? You haven't thrown that out there, just pissin in the sand! At least I said my solar guy told me double the amps and your good! SO is something 24 V 20 Amps in a switch appropriate for him or not? Or should a Nuclear Fusion device be better!!
In reality, OP could go to HOME DEPOT and buy a 110V 15amp home rocker switch as long as it is indoors and that will work!
