Solar Panel Fue

A wide range of voltage ratings and ampere ratings determine the solar panel fuse size.

Commercially made solar panels over 50 watts have 10 gauge wires capable of handling up to 30 amps of current flow. A solar fuse is a special purpose fuse used in photovoltaic pv or solar power systems. May 18 2020 1 this might be a dumb question but if i have 3 10 5a short circuit amperage solar panels in series do i need a fuse going from my panels to my charge controller. The second fuse between your solar panels and charge controller is a little bit different to figure out.

The cable is rated for 15a for the distance traveled. Maxi fuses are typically used for charge controllers or smaller inverters. Atc fuses are used for dc loads. This means each series needs a fuse breaker placed in the combiner box as shown here.

In this case the battery wires and ac dc inverter will be safely disabled by the fuse. Why use a fuse. No fuse needed in the solar pv loop generally till you get to 3 parallel panels strings. If you connect these panels in series there will be no increase in current flow so fusing is not required for this string.

It is essential to fuse the wiring between a solar panel set up and the battery bank for safety.

If the panels are connected in series the voltage of each panel is added but the amperage stays the same. With the positive and negative cables securely fastened to the battery terminals and the solar panel outside and exposed to the elements any cable connection failure is most likely to happen near the solar panel rather than at the battery.

A spare fuse is recommended with with the purchase of a fuse holder. At the battery install the fuse breaker at the terminal and then attach the charge loads to the other side of the fuse. 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.
