Caravans, Campers & Touring Power Solutions Built for real travel. Powered the right way.

At The 12V Lab, we design and install complete caravan and touring electrical systems that make off-grid travel simple, reliable, and stress-free. Whether you’re heading off for weekend getaways or long-term touring around Australia, your power system should just work — every time.

We specialise in caravan 12V systems, lithium upgrades, solar, DC-DC charging, and full off-grid setups, tailored to how you actually travel.

From fridge power and lighting through to full 240V inverter systems, we build solutions that keep you comfortable wherever you park up.

Caravan Electrical Systems Built for Australian Conditions

Caravans cop everything — heat, vibration, corrugations, long storage periods, and heavy power demands. That’s why a basic setup often isn’t enough.

We build systems that focus on:

• Reliable off-grid power for extended stays

• Safe and efficient lithium battery integration

• Proper charging from alternator, solar, and mains power

• Clean and professional installation (no messy DIY wiring)

• System monitoring so you know exactly what’s happening

Every install is designed to be safe, serviceable, and built to last.

Common Caravan Problems We Fix Every Week

If you’re experiencing any of the below, you’re not alone:

• Flat batteries after a night or two off-grid

• Fridge cutting out while travelling

• Solar not charging efficiently (or at all)

• Old lead-acid systems struggling with modern loads

• No idea how much power you’re actually using

• Overloaded wiring from DIY installs

• Fridges melting 12pin plugs

• incorrectly installed or setup DC-DC Chargers

We diagnose the system properly, find the weak points, and rebuild it so it works the way it should.

Caravan Systems We Install

We offer complete upgrades or targeted improvements depending on your setup and budget.

Lithium Battery Upgrades

Modern lithium systems give you more usable power, faster charging, and less maintenance compared to traditional batteries.

We supply and install complete lithium conversions including:

• Lithium batteries (sized to your setup)

• Battery management systems (BMS)

• Upgraded charging profiles for alternator + solar

• Safety fusing and isolation systems

DC-DC Charging Systems

Proper charging is critical for modern vehicles and caravans.

We install high-quality DC-DC systems to ensure:

• Correct charging from modern alternators

• Safe charging for lithium and AGM batteries

• Reliable power while driving

• Integration with solar systems

Solar Systems for Caravans

Stay off-grid longer with properly designed solar setups.

We design systems based on real usage, not guesswork:

• Roof-mounted solar panels

• Portable solar options

• MPPT solar regulators

• System matching to your battery capacity

240V Inverter Systems

Run household appliances while off-grid.

We install pure sine wave inverter systems for:

• Coffee machines

• Microwave ovens

• Chargers and tools

• Air fryer / appliances (where suitable)

All installed with proper protection and load management.

Caravan Power Management & Monitoring

Know exactly what your system is doing.

We can integrate:

No more guessing how much power you’ve got left.
