MC4 Connectors are included on most solar panels and can also be bought separately. MC4 Connectors have both a male MC4 and a female MC4 which are both needed for solar installations to connect together.

MC4 Connectors located on the solar panel will have a positive and negative wires attached to them. Generally speaking the male MC4 will be the positive wire and the female MC4 will be the negative. However, it is always recommended to test this first with an approved multimeter.

When connecting solar DC cable to the MC4s on your solar panel you will need to connect the male MC4 on the panel to a female MC4 you’ve bought separately. When connecting MC4 to MC4 you will need the metal connectors that come with your MC4s.

Our MC4 suppliers are leading manufacturers in the electrical connector industry. SMA and Elkay are both UK based manufacturers. Our MC4 connectors are all IP67 rated, UV stabilised, flame retardant and support 4mm and 6mm solar dc cable. Our MC4 connectors meet the requirement of IEC 62852.

TOP TIP: The metal connectors must be crimped on to your stripped DC cable using an approved crimping tool.
