Galaxy Solar MC4 Solar Panel Connectors

MC4 connectors are electrical connectors specifically designed for use in photovoltaic (PV) systems. They are used to connect PV panels to inverters, combiner boxes, and other electrical components in a PV system. These connectors are named after the company that developed them, Multi-Contact.

MC4 connectors are waterproof and designed to withstand harsh outdoor environments. They consist of a male and female component, with the male component having two pins that fit into the female component's sockets. The connectors are secured together with a locking mechanism, ensuring a secure and reliable connection.

MC4 connectors are widely used in PV systems due to their durability and ease of use. They are typically color-coded, with the male component being either black or red and the female component being either blue or white. This helps to ensure that the correct polarity is maintained in the PV system.
