MC4 connector is typically made from copper, with a tin plating to enhance their conductivity and corrosion resistance, it is specialized electrical connectors designed specifically for solar panels, inverters, DC combiner boxes, and other components in a photovoltaic (PV) system. MC4 connectors have become the industry standard due to their reliability, weather resistance, compatibility, cost-effectiveness, and easy installation and maintenance.
