Today, most solar panels come with approximately 3 ft. of Positive (‘+’) and Negative (‘-‘) wire. One end of each wire is connected to the junction box of the panel. In most solar panels, the other end of each wire is terminated with an MC4 connector. The Positive (‘+’) wire has a Female MC4 Connector and the Negative (‘-‘) wire has a Male MC4 Connector.
To extend the length of the wires of these solar panels for connection to a charge controller, combiner box or grid-connected inverter, an extension wire is required with corresponding Male and Female MC4 Connectors.
This product contains 1 male and 1 female MC4 solar panel connector. This type of connector system is easy to install and uses “snap-in” safety locking tabs to lock two mating connectors, thereby avoiding unintentional disconnection.
Once the connectors locked, the mating contacts are sealed against ingress of dust and water.
The MC4 connectors provided are compatible for use with AWG #10 or AWG #12 wire with outer insulation diameter 3.
