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 get very warm when charging say 10-16 amps. Fuses I have installed are 35 amp fuses. I have ordered car audio fuse holders and hoping maybe that will fix the heat issue. Wires themselves are not even warm. Anyone have this problem?

    Sounds to me like you likely have a poor connection at the fuseholder. Possibly removing and reinserting the fuse a few times would clear it up, at least temporarily. It may also be a wire connection to the fuse holder that needs attention.

    Using a better quality fuse holder (or perhaps just one more appropriately specified for the environment) could, at least in some cases, give a more permanent solution. Whether the replacements you've ordered are better or not is of course impossible for me to deduce without further information (and maybe not even then).
