Attaching the MC4 Connectors to the Solar Panel Extension Cable
After you have determined how the solar panels will be wired together (12 or 24 volt) and you have consulted
the appropriate wiring diagram in Appendix A, you will need to attach the MC4 Connectors to the solar panel
extension cable. The MC4 connectors provide a reliable and water resistant way for conveniently making
electrical connections between solar panels and the extension cable. Figure 4 and Figure 5 below outline
how to attach the MC4 Connectors to solar panel cable.
