Fuses are not required for series PV installations, as mine is. Go ahead, tear me apart.

NEC only requires fuses when you have 3 or more parallel strings. That's a minimum of 6 panels wired series/parallel. Anyone here have that kind of setup? When I get my solar setup, there will be no fuses on the panels to controller side. A hint on why: solar panels are designed to be shorted. You're not protecting those, you are protecting the wire and only when you have X number of panels connected will you ever stand a chance of going over a wires current limit.
