Shop Petrol Generators for Site Work and Backup Power

Petrol generators are the workhorses when you have a big job, a sudden blackout, or a site to power and you do not want to muck around. They crank up fast and deliver the juice for tools, lights and machinery.

Read more

They are built tough for real-world use, easy to load in the ute, and ready to fire when you need power on tap. If the job is a quiet night in a caravan park, or electronics that want cleaner power, look at portable inverter generators instead. Not sure how big to go? Start with our guide to what size generator you need.

What to Look for in Petrol Generators

Output that matches the job

Add up the tools, lights or machinery that have to run at once, then allow for the extra kick on start-up. A smaller petrol generator is enough for lights and a few tools. A site or a house backup wants more. Do not buy on the biggest number alone.

How you start it

Recoil start is fine on a smaller unit you use now and then. Electric start is worth having on a larger petrol generator you will fire often, or when you do not want to pull a cord on a cold morning.

Open frame, and what you plug in

Most of this range is an open-frame portable petrol generator: easy to load, easy to service, built for the job rather than for a campground. Check the outlets on the product page, including whether you need single phase or three phase, before you compare prices.

Petrol Generators by the Job

Tools and a day on site

This is the usual job. A portable petrol generator runs grinders, lights and the rest of the kit, then goes back in the ute. Size it to what is actually on at the same time.

House backup in a blackout

A petrol generator can cover a fridge, lights and a few circuits while the mains is down. Run it outside, clear of the house. If you want a unit that stays beside the house, see generators for home backup.

Welding and heavier plant

Some petrol generators are built to run a welder as well as ordinary power. If that is the job, match the unit to the welder, not just to a general worksite load. Check the product page before you assume any petrol generator will do it.

Frequently Asked Questions About Petrol Generators

Can I use a petrol generator as a camping generator?

Open-frame petrol can run a private block, but it’s rarely quiet or clean enough for a caravan park. For camping and van electronics, grab a portable inverter generator instead.

Which petrol 3 phase generator suits a workshop?

Match kVA to the motors that run together. Mid-size Honda three-phase sets cover lighter workshop plant; larger Gentech three-phase units step up when the load list grows. Confirm outlets and phase on the product page, or call us with the motor nameplates.

Can petrol generators charge my solar batteries?

Yep, a petrol set can power a proper AC charger or inverter-charger to top up the bank when you need it. Match the charger to the outlets and continuous watts, leave surge headroom, and never feed AC straight into the batteries. For quieter, cleaner charging power see portable inverter generators.

How do I choose the size of petrol generator?

Add up everything that has to run at once, then allow for tool or fridge start-up. A smaller unit covers lights and a few tools; a site or house backup wants more.

Do I need electric start?

Worth it on a larger set you’ll fire often, or if you don’t want to pull a cord. Recoil is fine on a smaller unit you only use now and then. Check out the product page for model specific info.

Can a petrol generator run a welder or three-phase gear?

Some can. A welder wants a unit built for that load, see generators for welding. Three-phase gear wants a petrol 3 phase generator matched to the motors. Don’t assume every unit will do either; check the product page or call us with what you need to run.
