About Photovoltaic panel mc4 plug

MC4 connectors are electrical connectors commonly used for connecting solar panels. The MC in MC4 stands for the manufacturer Multi-Contact (now Stäubli Electrical Connectors) and the 4 for the 4 mm diameter contact pin. MC4s allow strings of panels to be easily constructed by pushing the compatible connectors.

MC4 connectors are successors of the MC3 Connectors, which were developed by Multi-Contact in 1996. MC3 is the abbreviation of Multi-Contact and its size 3mm PV connector with 3 mm contact pin. MC3 had certification.

The MC4 system consists of a plug and socket design. The metal contacts of the plugs and sockets are inside plastic insulators; the plug's metal contact is inside a cylindrical insulator that looks like a socket, and the socket metal contact is inside a square probe.
