Fusing REQUIRED?
consider 6A Isc panels with 10g wire parallel 3, 1.56 x 6A x 2 = 19A parallel 4, 1.56 x 6A x 3 = 28A with lower amp panels, one does not need to fuse until 10g rating is exceeded by the numbe...
Forum Discussion
I'd suggest to install a manual trip circuit breaker between panels and charge controller. You may need to interrupt power from the panels at some time and a breaker with manual trip is made for that.
