MC-4 CONNECTOR
Description
The MC4 Connector (Multi-Contact 4 mm Connector) is a waterproof, UV-resistant electrical connector specifically designed for photovoltaic (PV) solar systems. It provides a secure and reliable connection between solar panels and DC cables, ensuring low power loss and long-term performance in outdoor environments.
MC4 connectors consist of male and female connectors with locking mechanisms that prevent accidental disconnection and provide excellent protection against dust and water.
