Solar Panel Fuse Rating
If you connect these panels in series there will be no increase in current flow so fusing is not required for this string.

What you need to know helping you understand what solar panel ratings are and why they are important to you. A wide range of voltage ratings and ampere ratings determine the solar panel fuse size. The class r fuse size operates at 600 vdc and from 20 to 400 amps.
For instance if you have one of our 40amp charge controllers we would recommend using an 40amp fuse. The midget fuse sizes operate from 600 to 1500 vdc and are available in 1 to 32 amps. The class j fuse size operates from 600 to 1000 vdc and from 70 to 600 amps. To determine the fuse size needed between the charge controller and battery bank you simply match the amperage rating on the charge controller.
Solar panel fusing commercially made solar panels over 50 watts have 10 gauge wires capable of handling up to 30 amps of current flow.
