MC4 connectors are single-contact electrical connectors. They are commonly used for connecting solar panels. MC4 stands for “Multi-Contact, 4 millimetre”. It is a standard in the renewable energy industry. An MC4 connector enables the easy construction of strings of panels. In today’s solar market, both MC4 connectors and their compatible products are used across the board. For the most part, larger solar panels will already come equipped with MC4 connectors. Solar panels are plastic-based round housings with single conductors in paired male/female configurations. With the help of a notched interlock, MC4 connectors are able to terminate to each other and avoid being unintentionally pulled apart.
