Pair of 5m single core extension cable leads 4.0mm for solar panels and solar charging kits
Pair of single core solar extension cables is specially designed for solar panels to carry high current and have negligible power loss. It comes with waterproof MC4 connectors ("male" on one lead, "female" on the other lead) which can be easily connected to similar MC4-type connectors coming with most solar panels.
This cable is suitable for all weather conditions including cold and hot temperatures.
4.0mm cross section is usually enough for off-grid 12V solar panels and systems up to 160W, or on-grid panels (typical voltage 30-60V) with higher power rating.
