ALVOLTA 10M 4MM Extension MC4 Solar Cables

Alvolta Twin extension leads:

Genuine Alvolta MC4 Twin extension leads are handy for extending the cables from the back of solar panels for grid or off grid, RV, 4x4 solar installations. These are available in 5M & 10M lengths & in either 4 or 6mm diameter. I.e If cut in half the 10M lead would give you twin 5 metre. The cable is 4-6mm2 (depending on model) you'll need to keep voltage drop to a minimum when selecting the appropriate length.

Alvolta MC4 PV connector from the Alvolta range which has become one of the most popular connector in the RV world. The MC4 plug connector is designed to accept 4-6mm2 solar cable. and is proven MC Multilam technology with high long term stability.  

MC4 connectors are single-contact electrical connectors commonly used for connecting solar panels. The MC in MC4 stands for the manufacturer Multi-Contact  and the 4 for the 4-mm diameter contact pin. MC4s allow strings of panels to be easily constructed by pushing the connectors from adjacent panels together by hand, but require a tool to disconnect them to ensure they do not accidentally disconnect when the cables are pulled. The MC4 and compatible products are universal in the solar market today.

The MC4 system consists of a plug and socket design. Oddly, the plugs and sockets are placed inside plastic shells that appear to be the opposite gender - the plug is inside a cylindrical shell that looks like a female connector but is referred to as male, and the socket is inside a square probe that looks male but is electrically female. The female connector has two plastic fingers that have to be pressed toward the central probe slightly to insert into holes in the front of the male connector. When the two are pushed together, the fingers slide down the holes until they reach a notch cut into the side of the male connector, where they pop outward to lock the two together.

For a proper seal, MC4s require the usage of a cable with the correct diameter. Normally double-insulated (insulation plus black sheath) and UV resistant (most cables deteriorate if used outdoors without protection from sunlight). Connection is made by use of a special crimping tool, alternatively by soldering.
