MC4 connector is a type of electrical connector commonly used in photovoltaic (PV) systems, particularly in solar panels. It is named after Multi-Contact, a Swiss company that developed the connector. The MC4 connector is designed to provide a secure and weatherproof connection for the wiring of solar panels. It is known for its reliability, durability, and ease of installation.
MC4 connectors consist of two main parts: a male connector (with pins) and a female connector (with sockets). They are designed to snap together easily and securely, creating a watertight seal to protect the electrical connections from moisture and other environmental factors.
MC4 connectors are widely used in both residential and commercial solar installations due to their compatibility with standard PV cables and their ability to withstand harsh outdoor conditions. They have become a standard in the solar industry for connecting solar panels to the electrical wiring of a solar system.
