I'm about to connect my 600W solar system (wired in series/parallel = 60V at 10A) to my 40A charge controller. I've determined a 15A fuse should be inserted between panels and CC. I'm wondering if a better option would be a DC 15A breaker that I could manually turn off if I wanted to shut the solar input off. Alternatively, I could insert 15A fuse in the line and add a DC disconnect switch. I'd like to put the switch or breaker box on the outside of my cabin near the panels if I go that route. Suggestions and sources for parts much appreciated as this is holding me up! Thanks.
