A quality portable generator can provide reliable backup power for caravanners who need extra capacity beyond solar and batteries — especially for high-demand appliances.
While solar and lithium systems handle most off-grid needs, generators still play an important role for many caravan travellers — particularly when running high-load appliances, camping in poor weather, or staying off-grid for extended periods.
The key is choosing a generator that’s quiet, efficient, reliable, and suitable for caravan use — not just the cheapest option available.
This guide compares five of the best caravan generators for off-grid power in Australia and explains when a generator actually makes sense.
Do You Still Need a Generator with Solar?
For many travellers, generators are used:
- As a backup during cloudy weather
- To run high-draw appliances (air con, induction cooktops)
- When staying off-grid for long periods
- In shaded camps where solar output is limited
Generators are no longer a primary power source for most caravans — but they can be a valuable safety net.
What to Look for in a Caravan Generator
Before choosing a generator, consider:
Noise Levels
Look for:
- Inverter-style generators
- Low dB ratings (important for campsites)
Quiet operation matters more than raw power.
Output Capacity
Common sizes:
- 1.8kVA–2.2kVA: Light to moderate loads
- 2.4kVA–3.0kVA: Higher draw appliances
Bigger isn’t always better — oversized generators are heavier and noisier.
Fuel Type
- Petrol: Most common, easy to source
- Dual fuel (petrol/LPG): Flexible and cleaner
- Diesel: Less common for portable units
Portability & Weight
Generators should be:
- Easy to lift or wheel
- Compact enough for storage
- Stable on uneven ground
Top 5 Caravan Generators for Off-Grid Power
1. Honda EU22i
Best for: Reliability and ultra-quiet operation
The Honda EU22i is widely regarded as the gold standard for portable caravan generators. It’s quiet, fuel-efficient, and extremely reliable.
Why it’s popular:
- Very low noise output
- Excellent build quality
- Stable power for sensitive electronics
It’s expensive — but built to last.
2. Yamaha EF2200iS
Best for: Smooth power delivery and durability
Yamaha’s EF2200iS offers strong performance with a reputation for smooth, reliable output.
Strengths:
- Quiet inverter technology
- Long service life
- Consistent performance
A solid alternative to Honda for long-term touring.
3. Redarc GoBlock + Generator Integration
Best for: Hybrid generator + battery systems
While not a generator itself, Redarc systems integrate well with generators to intelligently manage charging and load distribution.
Best suited to travellers running:
- Large lithium systems
- Occasional generator top-ups
4. Kings 2000W Inverter Generator
Best for: Budget-conscious travellers
Kings generators offer an accessible entry point for caravanners who want backup power without premium pricing.
Pros:
- Affordable
- Compact and portable
- Adequate for light loads
Not as refined or durable as premium brands — but workable for occasional use.
5. Briggs & Stratton P2200
Best for: Balance of price and reliability
Briggs & Stratton offers a good middle-ground option with reasonable noise levels and solid performance.
Good for:
- Backup power
- Moderate off-grid use
- Value-focused buyers
Generator vs Solar & Batteries: When Does It Make Sense?
Generators make sense when:
- You need short bursts of high power
- Weather limits solar generation
- You want redundancy
They make less sense when:
- You prefer silent camps
- You rarely exceed solar capacity
- You rely mostly on powered sites
Common Generator Mistakes
- Buying non-inverter generators (too noisy, unstable power)
- Oversizing and carrying unnecessary weight
- Running generators during restricted hours
- Using generators as a primary power source
Generators work best as support, not the centre of your system.
Planning an Off-Grid Power Setup?
Generators, solar, batteries, and charging systems all play different roles in an off-grid setup. The best systems balance capacity, noise, efficiency, and reliability.
