Where a fuse will not protect...

If one of the tiny traces or wires in the solar cell/panel conductive paths gets open, by fatigue, flaw, bad design, overcurrent somehow, the diarrhea hits the fan.

Pick any...

Keep in mind a blown fuse or blown path still presents a gap that spark can jump across. Even better if there is conductive/carbon residues deposited from when it blew. THAT is the core of the thing. Has nothing to do with vulgar street talk "shorted".

I may need to investigate if my inverter has built-in AFCI... and if such animal would be of any use. :(

Tis is why there are fuses with different voltage ratings, and likewise switches and relays. 600 volt fuses are much longer than 250 volt fuses, and fuses for 24 volts DC are shorter yet. And a 12 volt car fuse will keep arcing in a 120 volt application.
