A pair of solar-specific, UV-resistant cables with a 4mm² conductor cross-section. Supplied as 2 x 5m lengths with one end of each cable terminated with an MC4 connector (male and female) and the other end left un-terminated.

Ideally suited to connecting between a solar panel, equiped with MC4 connectors, and a solar charge controller.

As a guide, 4mm² cable is recommended for panels of 150W or more having a panel-to-controller cable length of 5m or more. If less than this, use 2.5mm² cable.

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