how

This will cause the wires leading to that panel to far exceed 30 amps causing that wire-pair to potentially catch fire. 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. Parallel/Combiner Box fusing

Fusing Solar Panel Arrays wired in Parallel. Now, in the case of 3 panels in series and 4 strings in parallel, if one string shorts, the max amperage to short is 39.12, which exceeds the 30 amp max current rating of the 10 AWG wire. This means each series needs a fuse/breaker placed in the combiner box as shown here:

Solar Panel Wiring Diagrams. Use the wiring diagrams below as a guide to putting together your DIY solar panel system. There are a few different ways to arrange panels, batteries, and connectors. These diagrams are designed to be understood by a beginner for a safe and effective install with readily accessible components.

For instance, if you have one of our 40Amp charge controllers, we would recommend using an 40Amp fuse. The second fuse between your solar panels and charge controller is a little bit different to figure out. The size of this fuse is dependent on how many solar panels you have and how they are connected (series, parallel, or series/parallel).

- Solar Panel to SCC should have a breaker or fuse, breaker is preferable as it can be used as a disconnect. -- 15A DC breaker would be sufficient for each set. BlueSea and others have high quality reasonably priced breakers. - SCC's out should also have a breaker, DC rated to the maximum amps output by the SCC.
