When you need a generator that can power tools, keep the campsite lit, or handle a home backup load, a 4kVA generator is the workhorse you're after. At Generators Australia, we've put together a strong lineup of proven 4kVA units — built for Aussie conditions and everyday use.

What Can a 4kVA Generator Power?

Home Backup and Essential Appliances

A 4kVA generator will comfortably run fridges, freezers, lighting, televisions, and basic power tools. It's a solid choice for keeping the essentials going during a blackout — without needing to invest in a larger, heavier unit.

Trade and Jobsite Use

4kVA is a popular size for tradies who need to run angle grinders, drills, and lighting on smaller job sites. It's portable enough to throw on the ute but powerful enough to handle a day's work without breaking a sweat.

Camping and Caravanning

For caravanners with a bit more gear — air conditioners, larger fridges, or multiple devices — a 4kVA unit provides the headroom you need. Inverter models at this size run quietly and efficiently, making them a great fit for camps and roadside stops.

Choosing the Right 4kVA Generator

Inverter vs Conventional 4kVA Generators

Inverter generators at 4kVA produce cleaner, steadier power — ideal for electronics and sensitive equipment. Conventional models at this size cost less and deliver raw output suited to tools and heavy loads. If noise is a concern, inverter is the way to go.

Key Specs to Compare

When comparing 4kVA units, look at continuous vs peak output, fuel tank size, run time per tank, and noise rating. Electric start is a handy addition for convenience, and AVR (automatic voltage regulation) protects your appliances.


4kva Generators FAQs

What will a 4kVA generator run?

A 4kVA generator gives you roughly 3,200-3,600 watts of usable power - enough to run a fridge, lights, power tools, and charge devices at the same time. On a job site it'll handle an angle grinder, drill, and site lighting no worries. Camping or in a caravan, you can run an air conditioner, microwave, and a few appliances simultaneously. Inverter models in this range are also safe for laptops and sensitive electronics.

How much does a 4kVA generator cost in Australia?

True Gear stocks 4kVA generators from around $1,100 up to $6,300 depending on the type and features. Open frame petrol models start from about $1,100-$1,300 and are solid workhorses for the job site. Enclosed inverter generators sit in the $1,600-$3,200 range - quieter and cleaner power for camping and RV use. Premium RV-spec units with advanced features can push past $6,000.

What brands of 4kVA generator does True Gear stock?

True Gear stocks 4kVA generators from Westinghouse, Champion, Hyundai, Welling and Crossley, and Macfarlane. Westinghouse inverter generators are a popular pick - reliable, well-priced, and backed by solid Australian support. Champion offers good value on both open frame and enclosed inverter models. Hyundai rounds out the range with quality inverter units and electric start.

What's the difference between an inverter generator and an open frame generator at 4kVA?

An open frame generator is your traditional workhorse - louder, heavier, but typically cheaper and built for continuous hard use on a job site. An inverter generator produces cleaner, stable power (safe for laptops, phones, and sensitive gear), runs quieter, and is more fuel-efficient at lower loads. If you're camping, caravanning, or running electronics, go inverter. If you need raw grunt for power tools and don't care about noise, open frame does the job.

Do 4kVA generators come with a warranty in Australia?

Yes - all generators sold through True Gear come with an Australian warranty. Coverage varies by brand: Westinghouse, Champion, and Hyundai models typically carry a 2-3 year domestic warranty. Because True Gear is an authorised Australian dealer, warranty claims are handled locally - you're not dealing with grey imports or overseas support lines.
