MC4 stands for the manufacturer Multi-Contact and a Ø4 mm contact assembly pin. MC4s 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 original MC4 connector has been installed over 1 billion times worldwide reaching an installed production capacity of over 100 GW.
