Double insulated single core cable together with polarised weatherproof DC connectors.
These allow fast, easy connection of solar modules, speeding installation time and eliminating wiring errors. Standard fitting on many PV modules and grid-connect inverters.
Special tools are required for crimping the connectors to the cable.

Note: Plug and socket connectors mated together in a PV system should be of the same type from the same manufacturer. Different brands may only be interconnected where a test report has been provided confirming compatibility of the two types to the requirements of BS EN 50521.
