Pair of MC4 3-To-1 connectors with terminals. Commonly used for connecting 3 solar panels in parallel before connecting to a solar controller, but can also be used for making triple-junction connections in more complex solar systems.

Consists of 1 male to 3 female, and 1 female to 3 male.

MC4 connectors are the industry-standard method for providing a waterpoof connection to solar panels and between solar cables. They suit cable of 2.5, 4.0 & 6.0mm² cross section and can be terminated either by crimping or soldering. A cable gland at the end of each connector ensures a waterproof seal when tightened around the cable insulation. Will connect to any other MC4 connectors.

Note: Never connect or disconnect MC4 connectors whilst they are under electrical load as this can cause arcing which can damage the contacts.


  • Voltage rating: 600VDC
  • Nominal current rating: 20A
  • Cable fitment: 2.5, 4 & 6mm²

Further information

The 'gender' of each connector is determined by looking at the terminal that is housed within it. The 'male' connector looks like a socket but houses the male terminal and the 'female' connector looks like a plug but houses the female terminal.
