I have that end covered. Proper fuses right at the battery terminals. And the solar panel is tied to the controller, not the batteries themselves. But there is some 25' of cable from the panel to the controller and I always wonder if that part should be protected as well. The solar panel is only 50 W, so it cannot produce too much current (and too much heat). But I wonder what it the proper way to connect it and protect it.

So the fuse should be as close as possible to where the wires from the solar panels tie into larger wires or bus bars (or the batteries if wired direct to the battery bank). As close as 6 inches if possible. Ken H.

Where would you put it? Outside, next to the panel? Or inside, as soon as the wire goes through the deck? I bet there are some rules of thumb. Thanks Marek 1994 C270 Legato Ottawa ON
