Gentech 20 kVA Electric Start Petrol Generator – Reliable Power When You Need It! If the thought of another blackout has you muttering “Not again!”...
View full detailsWhen the job needs power the mains will not reach, Gentech generators are built for it. Open-frame petrol and diesel units for the site, the shed, and home backup, with welder options when you need to strike an arc as well as run the tools.
Read moreGentech is a worksite brand. The range runs from compact petrol generators you can throw in the ute, through larger electric-start machines, to diesel units that earn their keep on long days. Single phase and three phase options sit in the same lineup, so you can match the power to the job instead of forcing one machine to do everything.
Not sure where this brand sits against the rest of the range? Have a look at petrol generators and diesel generators, or read our guide to diesel generators for home backup if the blackout is the main job.
The core of the range. Compact framed units for tools and lights, mid-size machines for the ute and the shed, and larger electric-start Gentech petrol generators when the load includes air compressors, welders, or a house circuit during an outage. AVR models smooth the output for gear that does not like a wild voltage swing. RCD options are there when the site rules call for them.
Heavier, longer-running Gentech diesel generators for farms, yards, and jobs that sit on power all day. Diesel sips less fuel under a steady load, and the framed build is meant to be rolled to the work, not packed into a car boot. Mine-spec versions are built for sites that ask more of the frame, the controls, and the way the machine is protected. If the job is backup at the house rather than a site, start with generators for home backup and size from the circuits you actually need to keep alive.
Gentech generators for welding pair a welding output with standard power outlets, so you can run stick work and keep the rest of the kit live. Petrol welder generators suit mobile jobs. Diesel welder generators suit longer days and heavier duty. If welding is the whole brief, the wider generators for welding collection is worth a look, and generators for mining covers the mine-spec side when the site demands it.
Both. The range includes Gentech petrol generators and Gentech diesel generators, plus welder versions of each. Petrol is the usual pick for portable site work and easier cold starts. Diesel suits longer run times and a steady load. Check the product listing for fuel type before you buy, because the frame can look similar across the range.
Welder models are built to do both, but not at full chat on both at once. Use the welding output for the arc, and the 240V outlets for lights, a grinder, or a small compressor. Add up the running watts of everything that will be on together, then leave headroom for the welder's demand. If welding is occasional and the generator is mainly for tools, a standard Gentech petrol generator with enough spare capacity can run a separate inverter welder instead.
Size it to the circuits you will actually run, not the whole switchboard. Lights, a fridge, a modem, and a few power points often sit comfortably on a mid-size Gentech generator. Add an air conditioner, a bore pump, or an electric oven and you need a larger unit, and you should check starting surge as well as running watts. A transfer switch or inlet, fitted by a licensed electrician, is the safe way to feed the house. Never backfeed a socket.
Yes. Run a new Gentech generator at a light to moderate load for the first few hours, then change the oil so the bedding-in metal comes out with it. After that, follow the manual for oil, air filter, and fuel filter intervals. Check the oil before every start. Low oil will shut many of these engines down on purpose, and that is easier to deal with than a dry start.
Do not run it in direct rain. Water on the alternator and outlets is a shock risk, and it will damage the electrics. Use a proper canopy or shelter that keeps rain off and still lets the engine breathe and the exhaust clear. Never run a Gentech generator indoors, in a garage, or in a closed van, even with the door open. Carbon monoxide does not care how good the machine is.
Most of this range is open-frame worksite gear. It is quieter than an old construction set at a distance, but it is not a whisper-quiet inverter suitcase. Fine for a private block, a shed, or a work camp. A shared caravan park will hear it. If the brief is a quiet night in the van, look at a portable inverter generator instead and keep the Gentech unit for the jobs that need the grunt.
