Caravanning in Australia is all about freedom and comfort. But when you’re off-grid, keeping your fridge cold, your lights on, and your air conditioner running requires reliable power. Without it, your adventure can quickly become inconvenient.
That’s where inverter generators and pure sine wave inverters come in. This guide covers everything you need to know about choosing the best caravan generator in Australia. We’ll explain the differences between generators and inverters, highlight key features to look for, and review some of the best models — including trusted options from RV Online such as myCOOLMAN, Aussie Traveller, and ATEM Power.
Inverter Generator vs Pure Sine Wave Inverter: What’s the Difference?
Before buying, it’s important to understand how each option works.
-
Inverter Generator: Produces electricity by burning fuel (usually petrol) and then inverts it into a clean, stable current safe for sensitive electronics.
-
Pure Sine Wave Inverter: Doesn’t generate power — it converts stored DC power from a battery or solar setup into usable AC power.
Why They’re Best for Caravans and Camping
-
Quiet operation: Many run at 50–60 dB — quieter than a conversation.
-
Stable electricity: Safe for appliances like laptops, CPAP machines, and fridges.
-
Energy efficiency: Generators adjust output to demand, while inverters rely on solar and batteries for silent power.
-
Compact design: Easy to store and transport in caravans.
💡 Tip: If your setup includes a strong solar + battery system, a pure sine inverter may be enough. For higher loads like caravan air conditioners, an inverter generator is essential.
Key Features to Look For in a Caravan Generator or Inverter
When choosing the best inverter generator in Australia, consider these factors:
1. Power Output (Wattage)
-
Add up the total demand: fridge (150W), lights (50W), laptop (100W), air conditioner (2000W+).
-
Choose a generator that covers both running and starting wattage.
2. Portability
-
Under 25kg is easier to handle.
-
Look for wheels or ergonomic handles for transport.
3. Fuel Source & Efficiency
-
Petrol is standard, while dual-fuel adds flexibility.
-
Inverters rely on batteries and solar — clean and quiet but dependent on stored energy.
4. Noise Level
-
Many caravan parks restrict generators above 60 dBA.
5. Safety Features
-
Overload protection.
-
Low-oil shut-off.
-
Surge protection.
6. Budget
-
Premium generators cost between $1,000–$2,500.
-
Inverters are often cheaper but require a battery setup.
👉 Helpful Tool: Use a caravan wattage calculator to work out your exact power needs.
