AVR Generator vs Inverter Generator

Both are excellent, but they are built for different jobs.

AVR Generators

Use automatic voltage regulation to hold a steady voltage as the load changes, which suits power tools, pumps, motors and higher output backup. Available in petrol and diesel from around 5kVA up to nearly 14kVA, they are the workhorses for farms, worksites and whole property backup.

Inverter Generators

Produce clean, quiet power that is ideal for sensitive electronics and lighter loads, and they are more portable. If you mainly need to run laptops, phones and a few essentials quietly, see our inverter generators range instead.

How Much Power Do I Need? Understanding kVA

AVR generators are usually rated in kVA, and the usable output in kilowatts is a little lower, so a 5kVA unit delivers roughly 4kW of real power. Add up the running watts of everything you want to power at once, then allow headroom for the surge that motors, pumps and compressors draw when they start. As a rough guide, 5kVA suits essential circuits and tools; around 7kVA suits a busy home or small worksite; and 11kVA to 13.9kVA handles a farm shed, multiple large loads or whole property backup. Note that the S12000 11.9kVA is a single phase unit. Prices in this range currently start from $1,775. See each product page for exact running and peak output.

AVR Generator Features Worth Looking For

Not every job needs every feature, but these are the ones that matter most for output and reliability.

  • ✓Automatic voltage regulationHolds a steady voltage as the load changes, which protects tools, motors and appliances from voltage swings.
  • ✓Petrol or diesel optionsChoose petrol for a lower purchase price, or diesel for better fuel economy and durability on long, heavy runs.
  • ✓Honda powered enginesSelect models run a Honda engine, known for reliable starting and strong parts and service support.
  • ✓Electric startStart at the push of a button rather than pulling a cord, which is welcome on the larger units.

Petrol or Diesel: Which Should I Choose?

Petrol generators cost less to buy, tend to be lighter, and are a solid choice for occasional or backup use. Diesel generators cost more upfront but use less fuel, run cooler under sustained load and generally last longer, which makes them the pick for farms, frequent use and long running jobs. If you expect to run the generator hard and often, diesel usually pays off over time; if it is mainly for occasional backup, petrol is the easier entry point.

Frequently Asked Questions

What does AVR mean?

AVR stands for automatic voltage regulation. It keeps the generator's output voltage stable as the load changes, which protects connected tools and appliances from the voltage swings that can occur on an unregulated generator.

Can an AVR generator power my house?

Yes, with a proper changeover switch installed by a licensed electrician. Larger single phase and three phase units have specific requirements, so it is important to have the connection set up correctly. Never plug a generator straight into a wall socket. Contact us to check what a specific model needs.

Are these suitable for power tools and motors?

Yes. Steady regulated voltage and higher output make AVR generators well suited to power tools, pumps and motors. Just check the surge rating against the startup draw of the largest motor you plan to run.

Do you offer a price match guarantee?

Yes. Found it cheaper elsewhere? Let us know and we will do our best to beat it.

Delivery Information

AVR generators are heavy items, and the larger units travel as bulkier freight, so delivery is quoted individually to get you the best price. Timing depends on your location and the size of the unit. Get in touch with your postcode for a shipping quote.
