Copper-Aluminum Solar Cable MC4 Connectors 1500V
Copper-Aluminum Solar Cable MC4 Connectors 1500V are a new-generation photovoltaic connector solution designed for direct copper-to-aluminum solar cable connections. They replace the traditional copper-aluminum tube crimping followed by nut locking with a more convenient quick-installation structure, helping improve installation efficiency in photovoltaic power stations and similar solar applications.
These solar cable MC4 connectors are engineered for reliable outdoor PV system performance. With PA66 insulation material, tin-plated copper-aluminum alloy contacts, 1500V DC rated voltage, IP68/IP65 protection, UL94V-0 flame retardancy, and low contact resistance, they provide secure connection and stable electrical performance in demanding solar environments.
