Solar Copper-Aluminum MC4 Connectors
Solar Copper-Aluminum MC4 Connectors are a new-generation connector solution for photovoltaic power systems. They are designed to replace the traditional copper-aluminum tube crimping and nut-locking method with a faster quick-installation structure, enabling direct and convenient copper-to-aluminum terminal connections.
These solar connectors are suitable for photovoltaic power stations and similar solar applications where reliable electrical performance, corrosion resistance, and fast installation are required. With PA66 insulation material, tin-plated copper-aluminum alloy contacts, 1500V DC rated voltage, and IP68/IP65 protection rating, they support stable performance in demanding outdoor PV environments.
