MC4 Connectors Solar PV Panels

MC4 Solar PV Connectors

MC4 Connectors are single-contact electrical connectors commonly used for connecting solar panels.

MC4 Connectors stand for the manufacturer Multi-Contact and a 4 for the 4mm (diameter) contact pin pin. MC4s allow strings of panels to be easily constructed by pushing the connectors from adjacent panels together by hand. They require a tool to disconnect them to ensure they do not accidentally disconnect when the cables are pulled.
