Inverter Generators for Quiet, Reliable Backup Power

An inverter generator gives you clean, quiet power you can trust for sensitive electronics, backup during outages and life off the grid. This range features Cromtech, iTechWorld RedBack and Pramac models from a compact 2.4kW unit up to a 7kW machine with an automatic transfer switch, so you can match the output to everything from a weekend away to keeping the essentials running at home.

Inverter Generator vs Conventional Generator

Both make power from petrol, but they do it differently, and that changes what they are best suited to.

Inverter Generators

Produce clean, stable power that is safe for laptops, phones, TVs and other sensitive electronics. The engine adjusts its speed to match the load, so they are quieter, more fuel efficient and lighter to carry. The natural choice for camping, caravans, sensitive gear and quiet backup at home.

Conventional Generators

Run the engine at a constant speed to make power, which can be cheaper for the same output but tends to be louder and less refined. They suit worksite tools and pumps where raw output matters more than clean power or a quiet run.

How Much Generator Power Do I Need?

Add up the running watts of everything you want to power at once, then allow extra headroom for the surge that motors, fridges and pumps draw when they start. As a rough guide, a 2.4kW unit covers camping and a handful of essentials; 3.5kW runs several appliances at once; 4.5kW suits the essential circuits of most homes; and 6.5kW to 7kW handles heavier loads or a worksite. The Cromtech 7000IA also includes an automatic transfer switch for hands free changeover during an outage. Prices in this range currently start from $1,269. See each product page for exact running and peak watts.

Inverter Generator Features Worth Looking For

Not every job needs every feature, but these are the ones that matter most day to day.

  • ✓Clean sine wave powerStable output that is safe for laptops, phones, TVs and other sensitive electronics.
  • ✓Quiet operationAn enclosed design and a variable engine speed keep the noise down, so they are far easier to live with.
  • ✓Electric startStart at the push of a button rather than pulling a cord, which is handy in the cold or the dark.
  • ✓Automatic transfer switchSelect models switch to generator power automatically when the mains drops out, so backup is hands free.

How Do I Look After an Inverter Generator?

A little upkeep keeps a generator starting first time when you need it. Change the oil after the initial run in and then at the intervals in the manual, keep the air filter clean, and use fresh fuel with a stabiliser if it will sit for a while. Run the generator every so often between uses, and always store it somewhere dry. Follow the maintenance schedule in your model's manual for the details specific to that unit.

Frequently Asked Questions

What can an inverter generator run?

It depends on the output. Smaller units handle lights, chargers, a fridge and small tools, while larger 4.5kW to 7kW models can run the essential circuits of a home. Add up the running watts of what you want to power, and allow headroom for the surge when motors and fridges start.

Are inverter generators safe for sensitive electronics?

Yes. Inverter generators produce clean, stable power similar to mains supply, which makes them well suited to laptops, phones, TVs and other sensitive gear that can be damaged by rougher power.

Can I connect one to my house?

Powering the house wiring safely needs a proper changeover switch installed by a licensed electrician, and some models include an automatic transfer switch for this. Never plug a generator straight into a wall socket. See the product page or contact us to check what a specific model needs.
