Im shortly going to fit a 200w Solar Panel and would like some wiring advice. I have looked at diagrams clearly showing the method, panel to MPPT controller and to batteries, all quite straightforward. However, I have also seen mentioned perhaps a switch to isolate the panel, and possibly fuses. Could someone who knows point me in the right direction with the best wiring solution, belt and braces, for function and safety, perhaps a simple diagram, thanks.
