What this video covers
Installing a 100-watt solar panel requires a fuse between the solar controller and the battery bank to protect the circuit. A 10-amp fuse is appropriate for a 100-watt panel, which typically outputs a maximum of 5 to 6 amps.1:55 ATO or ATC automotive blade fuses are preferred over glass fuses because they are color-coded for easy identification and allow for quick visual inspection of the filament.0:53 Some blade fuses include integrated LEDs that illuminate when the fuse blows, simplifying troubleshooting.0:59 When selecting a fuse holder, ensure it is rated to handle the continuous amperage of the solar array, especially as system size increases to 400 or 500 watts.1:56 Always carry a complete set of spare fuses on board to address potential nuisance tripping or unexpected failures.3:10
