Custom 12V & 24V Power Systems Built For Your Vehicle
We are 12V & 24V power specialists servicing the Southern Downs and Toowoomba regions. Designing and installing custom 12V & 24V systems for 4WDs, caravans, motorhomes, vans and utes using quality components including Victron and Australian-made batteries. Every system is designed around what you want to run, how long you will be away and the vehicle you’re driving. Our customers have completed four-month remote trips across Australia without plugging into mains power once. We are also authorised suppliers and installers of Bushman 12V fridges.
Off-Grid Power
4WD and Caravan Off-Grid Power Setups for Remote Trips
When you are spending weeks away from the grid, a power system that has been properly designed from the start makes all the difference. We build complete off-grid setups with solar panels, a dual battery system and DC-DC charging so your fridge stays cold, your lights stay on and you stay out as long as you want. Our customers have run air conditioners and induction cooktops completely off-grid on four-month remote trips without touching mains power. We size every system correctly for what you are running, so nothing is undersized and nothing is wasted. Whether you are in a 4WD, caravan, or motorhome, we will design a setup that works for you.
OUR APPROACH
Quality Comes First, Every Single Time
We stick to high-end gear like Victron and Australian-made batteries because they actually last. Our focus is on clean, professional wiring and setups that are done right the first time. You get a reliable system without the guesswork, built to handle exactly what you need it to do.
