MC4 Male and Female IP67 Solar connector
MC 4 connectors are single-contact electrical connectors commonly used for connecting solar panels. The MC in MC 4 stands for the manufacturer Multi-Contact and the 4 for the 4 mm diameter contact pin. MC 4s allow strings of panels to be easily constructed by pushing the connectors from adjacent panels together by hand, but require a tool to disconnect them to ensure they do not accidentally disconnect when the cables are pulled. The MC 4 and compatible products are universal in the solar market today, equipping almost all solar panels produced since about 2011. Originally rated for 600 V, newer versions are rated at 1500 V, which allows longer strings to be created.
