Extension Leads

If you've ever parked your solar panels in the sun only to realise your battery's just out of reach, you'll know exactly why extension leads are essential. Whether you're stretching from rooftop panels to an auxiliary battery or positioning a solar blanket in the best light while keeping your setup in the shade, extension leads give you the flexibility to make the most of your power system.

Our extension leads are built with thick copper wiring and fitted with quick-connect plugs, so they're ready to plug straight into your existing setup without mucking around. Heat, water, and abrasion-resistant outer sheaths mean they'll handle dusty tracks, summer scorchers, and the odd accidental tug without drama. Available in various lengths and wire gauges, they're designed to minimise voltage drop and keep your charge flowing efficiently.

Whether you're running solar panels, portable lights, or connecting other 12V accessories, having the right extension lead makes the difference between a frustrating setup and one that just works. Pair yours with our quick-connect accessories for a complete plug-and-play system, or check out our 50A wiring kits if you're building out a more permanent installation.

And if you're putting together a full 12V system from scratch, our wiring and connectors range has everything you need to wire it up properly the first time.
