Fuse size?
I need to put a fuse in the positive line between battery and solar controller. I currently have 100 watts but may go to 200. Will a 30 amp fuse be enough? Thanks.............DJ

My decision was I dont want controller (or the wire) to see what the battery might supply/carry untill it melts if an issue? What the scenerio might be to allow that I havent a clue. Fuses are cheap and easly replaced.
Ours 135 watt~7.6 amp panle, 30amp controller, 10ga wire. Used 15amp fuses on both positive and negative legs. 5 amp fuses on the 18ga sensor wires. 10 amp on the 16ga positive lead for load output. Fuses are cheap, needed or not I use on both sides. Electrically try to build in some over kill, but fuses I always go opposite (underkill?) less I need to see full potential of components. IE auxillary 10ga charge line is fused at 30amp. But from controller to battery, I dont know why fused beyond its output? Restriction/resistance?
