MC4 connector, formally known as Multi-Contact 4mm connectors, play a pivotal role in solar energy systems. These electrical connectors are specially designed for connecting photovoltaic solar panels.

MC4 connector consist of a male and a female connector, which lock together to form a secure and stable electrical connection. The connectors are designed with a single-contact point surrounded by a robust and waterproof housing. This design is crucial for outdoor environments where solar panels are typically installed.

The “MC” in MC4 stands for Multi-Contact, and the “4” refers to the 4mm diameter of the contact pin, which is the standard size. These connectors are manufactured to comply with several international standards for solar connectors, ensuring compatibility and reliability across different solar systems.
