Why REDARC Is Worth It
REDARC isn't the cheapest power gear you can buy — and there's a good reason we fit so much of it. Here's what sets it apart.
45+ Years, Australian Made
Founded in South Australia in 1979, REDARC has spent over 45 years designing, building and testing power electronics — still made at its Lonsdale facility and exported to more than 35 countries.
Tested in the Extreme
Every product is built to handle harsh conditions because REDARC tests them in it — simulating dust, vibration, heat and electrical stress well beyond normal use. Ideal for NZ's varied roads and climate.
One Integrated System
Chargers, battery management, inverters and RedVision control are designed to work together — so your whole power setup behaves as one system, not a box of mismatched parts.
Proven & Backed
Trusted by 4x4, touring and industry users the world over, with a strong warranty behind it. When you're a long way from help, gear you can rely on matters more than a few dollars saved.
REDARC's range extends well beyond what's shown here — including smart battery isolators, brake controllers, gauges and more. If you're after something REDARC makes that isn't listed, just ask us.
