Diesel Inverter Generators FAQs
What's the difference between a diesel inverter generator and a regular diesel generator?
A regular diesel generator puts out raw AC power that can fluctuate - fine for power tools and pumps, but risky for sensitive electronics. A diesel inverter generator converts the power to DC and back to clean AC, giving you stable voltage and frequency. That makes it safe for laptops, phones, medical equipment, and modern appliances. You also get quieter operation and better fuel efficiency at part load, which matters a lot on a long trip or at a remote worksite.
What are diesel inverter generators best used for in Australia?
They're a solid choice anywhere you need reliable power away from the grid and want something that'll run all day without burning through fuel. Popular applications include remote worksites, caravan and RV setups, 4WD touring, farm backup power, and off-grid cabins. The fuel efficiency and clean output make them especially good for extended trips where you're running a fridge, CPAP, or other sensitive gear around the clock.
How much does a diesel inverter generator cost in Australia?
Expect to pay more for diesel inverter than petrol inverter - the technology and fuel system cost more to build. True Gear stocks diesel inverter generators starting around $16,999 for a quality 6kVA unit suited to RV and remote applications. The higher upfront cost is often offset by lower running costs, since diesel is more fuel-efficient and the engines tend to have longer service lives.
What size diesel inverter generator do I need?
Add up the wattage of everything you plan to run at the same time - that's your baseline. A 3-4kVA unit covers most camping and small caravan setups. A 6kVA handles a larger RV or light worksite loads. If you're running air conditioning, multiple power tools, or a whole-home backup setup, you're looking at 8kVA or more. When in doubt, size up - running a generator at 70-80% capacity is better than flogging it at full load all day.
Do diesel inverter generators come with a warranty in Australia?
Yes - the units True Gear stocks come with manufacturer warranties backed by Australian dealers. Warranty terms vary by brand and model, so check the individual product listing for specifics. When you're buying a generator at this price point, it's worth confirming that parts and service are available locally - ask True Gear if you're unsure about support in your area.
