Off-Grid Vehicle Power Systems Warwick
Run your fridge, lights, and accessories without a power point in sight. Coast Customs 12 Volt builds complete off-grid power systems for 4WDs, caravans, utes, camper trailers, and work vehicles across Warwick and the Southern Downs.
Power Your Vehicle Anywhere, Without the Grid
An off-grid vehicle power system lets you run everything you need, whether you are camping for a week in the bush, working on a remote job site, or travelling long distances between towns. Without the right setup, you are relying on your starter battery, which is not designed for that kind of sustained load. Coast Customs 12 Volt designs and installs vehicle off-grid systems that combine solar, auxiliary batteries, and smart charging so your vehicle is fully self-sufficient, no caravan park or power point required.
- Rooftop solar panels for 4WDs, utes, caravans, and camper trailers
- Auxiliary and lithium battery installation for deep-cycle power storage
- DCDC chargers to harvest alternator power efficiently while driving
- 240V inverters to run mains appliances from your vehicle battery
- 12V fridge, lighting, water pump, and device charging circuits
- Battery monitors so you always know your state of charge
Vehicle Solar Systems
We mount and wire solar panels directly to your vehicle roof, ute tray, or caravan, connecting them through a quality MPPT charge controller that maximises output and protects your battery. Free power from the sun, every day you are out there.
Auxiliary Battery Systems
A dedicated auxiliary battery keeps your fridge, lights, and accessories running without touching your starter battery. We size and install the right battery for your load, AGM or lithium, and wire it safely with proper fusing and isolation.
DCDC Charging & Inverters
DCDC chargers top up your auxiliary battery from your alternator every time you drive. Add a 240V inverter and you can run power tools, laptops, or appliances directly from your vehicle battery when you reach the destination.
How We Build Your Off-Grid Setup
Every system is designed around your vehicle and how you use it.
Understand Your Needs
We find out what you need to run, how long you are away from power, and what vehicle you have. This drives every decision in the design.
Design the System
We select the right solar wattage, battery capacity, DCDC charger, and inverter so the system is neither underpowered nor unnecessarily expensive.
Professional Installation
Every component is fitted securely, with cables correctly sized and routed, fuses at the source, and a finish that looks and works like it belongs in the vehicle.
Test & Hand Over
We run the full system through its paces, confirm everything is performing correctly, and walk you through how to monitor and manage your power on the road.
