MC4 FemaleMC4 Connectors

MC4 connectors are single-contact connectors commonly used for connecting photovoltaic panels. MC4 stands for the manufacturer Multi-Contact and a 4 mm2 contact assembly pin. The MC4 connector is UL rated at 20A and 1000V DC maximum, depending on the conductor size used.

While small solar panels used for battery charging for example, may not require special connectors, larger terrestrial arrays for power generation involve higher currents and voltages, and place special demands on both cables and connectors for safe operation. The MC4 connectors and leads incorporates a flexible watertight seal and is supplied as ‘male’ and ‘female’ type to minimise the chance of wrong connections.

For a proper seal, MC4s require the usage of a cable with the correct diameter. Normally double-insulated (insulation plus black sheath) and UV resistant (most cables deteriorate if used outdoors without protection from sunlight). Connection is made by use of a special crimping tool, alternatively by soldering.
