Solar combiner box
Anyone made there own combiner box if so how and what did you use. Am solar has one for $80 but I am sure it can be built for a lot less.

I don't see a reason for a fuse at the box. Unless there is something I am not aware of. I have a 50 amp circuit breaker between the panels and the controller.
The 50 amp breaker will do nothing for a panel failure or a wire short for that matter. Do you REALLY believe a 30 amp source would EVER trip a 50 amp breaker? I agree that you need a switch there and it will serve OK for that. Electricity will ALWAYS take the path of least resistance. If a panel short's out ALL of the 28 amps will go to that panel. Even if it doesn't start a fire, melted EVA could cost you a new membrane roof. I would also rather have 3/4 of a array then NO array while camping. But other then that I see no reason to fuse there. :R
