This is a single core solar extension cable 4.0mm cross section which is specially designed for solar panels to carry high current and have negligible power loss. It comes with waterproof MC4 connectors (“male” on one end, “female” on the other) which can be easily connected to similar MC4-type connectors coming with most solar panels, including Photonic Universe 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.
The cable can be cut in half if required to make two 2.5m tails.
