solar system connector

MC4 connectors are a popular type of electrical connector commonly used to connect solar panels. The term "MC" stands for Multi-Contact, the original manufacturer (now Stäubli Electrical Connectors), and "4" refers to the 4 mm diameter of the contact pin. These connectors allow for easy, tool-free connection of solar panel strings by simply pushing the connectors of adjacent panels together. However, a specialized tool is needed to disconnect them, providing a secure connection that prevents accidental disconnection if the cables are pulled.

These connectors make it simple to join solar panel strings by hand, as adjacent panels' connectors can be easily pushed together. However, a specialized tool is required to disconnect them, ensuring they remain secure and don’t accidentally come apart if the cables are tugged.
