Hot to touch fuse (solar) UPDATE
I've installed my solar charging system myself. I have it fused both from panels to controller and also from controller to batteries. Wire gauge used was 8awg. I've just recently noticed both fuses...

Unless you're really enamored of having fuses from PV to controller, they're not needed. Likely a poor connection, kinda like having clip-on jumper cables...not really much surface area there.
