What size fuse or circuit breaker for a solar panel string? To determine the normal fuse or breaker size use this equation: String circuit ampacity = Short Circuit Current (Isc) X 1.56=Fuse Size.

What size fuse or circuit breaker for a solar panel string? To determine the normal fuse or breaker size use this equation: String circuit ampacity = Short Circuit Current (Isc) X 1.56=Fuse Size.

In the case of panels in parallel, a 30-amp fuse is required for each panel. If your panels are smaller than 50 watts, and use only 12 gauge wires, and 20 amp fuses are required.

The lowest fuse we can use is: 10A*1.56=15.6A The highest fuse size we can use is 40A because the maximum current for a 10AWG wire at 90° insulation temperature is 40Amps.

The solar fuse can be chosen based on several factors such as physical size and shape, amperage rating, breaking capacity, and many more.

Once you have this number, you can calculate the size of fuse you need using this formula: Fuse Size (in amps) = Maximum Current Output (in amps) x 1.25 For example, if your solar panel has a maxim.
