Overlanding isn’t just about getting from A to B—it’s about the journey. And if you’re heading off-grid for days or weeks at a time, powering your gear becomes essential to comfort, safety, and independence.
At All 12 Volt, we’ve helped thousands of 4WDers set up robust 12V power systems that stand up to Aussie conditions. In this guide, we’ll show you how to build a reliable, scalable 12V setup for your next overland adventure—so you can explore further, stay longer, and travel smarter.
When you’re hundreds of kilometres from the nearest town, you need power you can count on. A complete 12V setup allows you to:
Keep food cold
Light up your camp
Charge devices and tools
Run air compressors, fridges, or even small appliances
Stay off-grid indefinitely with solar
No noisy generators. No worrying about running out of charge. Just silent, dependable power.
A dual battery system separates your starter battery from your auxiliary power, so your vehicle always starts—no matter how long you’ve been camped.
ZENOT 135Ah Lithium Battery
ZENOT or Redarc DC-DC Charger (40A)
Battery Box or fixed tray install
Fuses on all major lines
Lithium is lighter, charges faster, and lasts longer—perfect for 4WD rigs.
Solar keeps you powered even when your wheels aren’t turning.
200W–300W folding solar panels
Blanket panels for roofrack flexibility
Built-in solar input via your DC-DC charger
A good solar setup means you can stay off-grid indefinitely—even without driving.
What should your system power? Here’s a typical overland loadout:
12V Fridge/Freezer (ZENOT 45L–75L)
LED Strip Lights (awning, tailgate, canopy)
12V Sockets & USB Ports (charging)
Inverter (for laptops or drone batteries)
Water pump (for showers or drinking water)
Air compressor (tyre inflation)
Use a battery monitor to track draw and voltage in real-time.
Use a smart distribution hub or battery box with:
Inline fuses
Anderson plug connectors
USB, cig, and 50A ports
Built-in voltmeter or Bluetooth monitoring
We recommend the ZENOT Extreme Battery Box for its rugged design and multiple power outputs.
Overlanding setups work best when they’re:
Modular: Easy to swap or expand
Accessible: Clear wiring and labelled circuits
Safe: Fused, insulated, and protected from vibration
Use cable ties, split tubing, and waterproof connectors throughout.

ZENOT 135Ah Lithium Battery

200W Folding Solar Panel
ZENOT Battery Box
