This course includes video demonstrations on how to form a reliable MC4 connector, and how to form a split-bolt connection for high current carrying capacity split-bolt wires. Video demonstration of solar cables and heavy gauge wire lugs soldering connection forming techniques This course includes ...
Ahard ground faultis a sustained, low-resistance connection between the current-carrying wire and the metal part. This connection remains unbroken over time. Anintermittent faultis more challenging to locate. It happens when the current-carrying wire occasionally connects to the metal part. A connec...
If you’re an installer, the module you’re using was probably made to use this connector to attach to the junction box on the back of the panel. The junction box will contain two wires. The female MC4 connector does usually connect to the solar DC wiring using one wire, the DC ...

remove the negative conductor of the first string from the negative busbar and connect it to the negative lead from the meter. (If the combiner has fuses on the negative side, you can open the fuse holders instead of removing the wire. Close one fuse holder at a time to test that strin...
