Exotronic 6mm² Twin MC4 Compatible Solar Extension Cable - 1m, 3m, 5m, 10m

The Exotronic 6mm² Twin Solar Extension Cable provides a simple way to extend the distance between your solar panels and the rest of your solar system without needing to cut and terminate additional cable. Available in 1m, 3m, 5m and 10m lengths, each lead uses 6mm² tinned copper solar cable with pre-terminated MC4 compatible connectors, making it well suited to 4WDs, caravans, campers, boats and other off grid solar installations.

The twin cable keeps the positive and negative conductors together for a neater installation, while still allowing them to be separated where required for routing or connection. Shorter lengths are useful for extending roof mounted panels or repositioning an existing connection, while the longer 5m and 10m options are particularly handy for portable solar panels where you want the flexibility to move the panel into better sunlight while keeping the vehicle or camper in the shade.

6mm² Tinned Copper Cable

Each conductor uses 6mm² tinned copper cable, providing a low resistance connection suitable for higher current solar installations and longer cable runs.

Using an appropriately sized conductor helps reduce voltage drop between the solar array and regulator, but cable size should still be checked against the actual current and total cable length of your system.

For long low voltage solar runs, voltage drop can become significant even when the cable is safely within its current carrying capacity.

Pre-Terminated MC4 Compatible Connectors

Each extension lead is supplied ready to connect, with MC4 compatible solar connectors fitted to both ends. The snap locking connectors provide a secure connection and carry an IP67 protection rating when correctly mated.

This makes the leads convenient for extending existing solar panel cables, connecting portable panels or adding distance between a fixed array and regulator without needing to crimp new connectors.

Suitable for Fixed & Portable Solar

These extension leads are useful across a range of solar installations, including:

• fixed roof mounted solar panels

• portable and folding solar panels

• caravan and camper solar systems

• 4WD canopy installations

• marine solar systems

• remote and off grid installations

For portable systems, longer cable gives you more flexibility when positioning the panel, although increasing cable length also increases voltage drop.

Rated to 30A

The cable assemblies are rated to 30A and up to 1000V DC under the stated IEC specifications. The complete solar system should always be designed around the lowest rated component in the circuit, including the solar panels, connectors, extension cable, branch connectors, fuses and solar regulator.

MC4 Compatibility Note

These leads use MC4 compatible connectors rather than genuine Stäubli Original MC4 connectors. For permanent installations, it is best practice to avoid cross mating different solar connector brands unless the manufacturers specifically approve the combination. Connectors can physically fit while having different contact geometry, sealing tolerances or materials.
