The Best Caravan Power Setup for Full-Time Travel

Planning the Big Lap? You're in good company. Australians took 15.2 million caravan and camping trips in the year to 2024, with over 901,000 caravans and campervans now registered across the country. A good chunk of those are full-timers: grey nomads, semi-retirees, and serious adventurers who've swapped the mortgage stress for red dirt roads and star-filled skies.

But here's the thing that catches most new full-timers off guard. What works brilliantly for a fortnight away doesn't cut it when you're living on the road full-time. Power becomes your single biggest logistical challenge, and getting it wrong means warm beer, dead phones, and a fridge full of regret somewhere past Longreach.

Here's what a proper full-time caravan power setup actually looks like.

Quick Takeaways

• Full-time travel demands significantly more power capacity than occasional camping, so size for bad days, not good ones
• Lithium (LiFePO4) batteries are the go-to for full-timers: more usable capacity, longer lifespan, less weight
• Aim for 400–800W of solar and 300–600Ah of battery storage as a baseline for full-time use
• A DC-DC charger keeps your batteries topped up every time you drive 
• A quality inverter (2,000–3,000W) handles your 240V appliances: coffee machine, microwave, induction cooktop

Full-Time Power Is a Different Beast

Weekend campers can get away with a single AGM battery and a couple of solar panels. Full-timers can't. You're running a fridge 24/7, charging laptops and phones daily, watching TV at night, possibly running Starlink, and in hot months, firing up an air conditioner. A Starlink setup alone can draw as much power as a running fridge.

The key shift in thinking is this: stop sizing your system for a good day, and start sizing it for a bad one.

The Four Pillars of a Full-Time Setup

1. Lithium Batteries 

Lithium (specifically LiFePO4) is the standard for full-time travel. You get more usable capacity, faster charging, a longer lifespan, and significantly less weight than AGM. For full-time use, aim for a minimum of 200–300Ah, but most serious travellers run 300–600Ah or more when you factor in air conditioning and home-style appliances. Outback SafeTrack stocks a solid range of lithium camping batteries, from compact options through to high-capacity banks built for long stints off-grid.

2. Solar 

For full-time travel, aim for 400–800W of solar panels paired with 200–400Ah of battery storage. Roof-mounted panels are the workhorse; portable solar panels give you the flexibility to angle towards the sun when you're parked under a tree or in an awkward spot. Having both is ideal.

3. A DC-DC Charger

When travelling full-time, solar alone isn't always enough, especially on cloudy days or when parked in shade. A DC-DC charger is a game-changer, topping up your batteries every time you drive. Even a short run between camps makes a real difference to your state of charge.

4. An Inverter

For running 240V appliances, you need a quality camping inverter sized to handle your peak loads. A 2,000–3,000W pure sine wave inverter comfortably covers most full-time setups.

The Easiest Way to Sort It

If you'd rather not piece it all together yourself, off-grid power systems and caravan power stations bundle the key components (batteries, inverter, and monitoring) into a single solution. It takes the guesswork out of compatibility and sizing, which is a big deal when you're new to full-time travel.
