So I was looking through plans online for combiner boxes and the way these things are being wired from an electrical standpoint just doesnt make sense to me.
So if I built four panels that output 10 amps at 24v's and I wanted to put a 15 amp breaker on each panel - this is how I am seeing it done:

This doesnt make any sense to me because fuses and breakers (most) are bi directional. So when the current passes through the first set of 15a breakers it could easily just feed back up the line and blow the breaker or fuse next to it.
Am I missing something? How are people wiring these boxes so they input into a single slot on a charge controller? It seems like there would have to be an isolator or a diode for each panel between the 15a fuse and the 50a fuse.
Thanks for the help
