Product Description

Get the advantage of reliable, economical power around your worksite. With a legendary Honda V Twin GX630 engine, this generator delivers 12.5 kVA 3-phase in a portable package with a handy electric start. As soon as you start the generator, you’ll know you’ve made the best choice for your farm or worksite.

The 27-litre fuel tank promises 7.11 hours of operation at 80% load. And with only 3.8 litres per hour fuel consumption, you get more power for your buck. This generator can provide 1-phase (third of the load) or full capacity 3-phase power with all the grunt you need for welders, compressors and other heavy duty equipment.

Designed for maximum performance, you can add on a remote start and wheel kit to create the perfect trade generator package.

Please note that the single phase (230-240V) outlet produces one third of the generator's power capacity.

The package is complete with a 2 year generator warranty backed by a national service network. The Honda engine comes with a 3 year warranty.

This product is ‘Honda Australia Approved’ - meaning that the Honda engine used in an Original Equipment Manufacturers (OEM) product, has been engine match tested by Honda Australia, is a genuine Honda engine and meets their strict quality and operational standards, and is backed by their national service agent network. The following table outlines the new extended warranty for the different Honda engine types:

Product Q&A

Ask Us a Question
  • Hi, there are two generators listed, one is a Gentech, one is a Dunlite - They look similar, but slightly different pricing. What is the difference in the generators? Regards, Neville

    Hi Neville, great question. Dunlite & Gentech are both built / distributed by an Australian company called Welling & Crossley. They have been Australian owned and operated since 1926, and are recognised as an Australian leader in the manufacture and supply of petrol & diesel power equipment and generating sets for industrial, commercial and domestic applications.

    Welling & Crossley's range of portable generators has always been Gentech. Then around 20 years ago, they acquired a similar portable generator brand in Dunlite. Each brand has excellent recognition throughout Australia. So both brands now come out of the same Welling & Crossley factory and so the models are not just similar, but the same – either branded ‘Gentech’ or ‘Dunlite’.

    In the instance where the price is slightly different, this just relates to stock levels and availability of that particular model. In any case, there are Dunlite/Gentech portable petrol generators from around 2kVA to 16kVA in size, mostly powered by genuine Honda engines and are the trusted option for tradesmen, farmers, industrial applications, domestic requirements, small businesses and much more... similarly, the Dunlite/Gentech diesel portable generator models up to around 9kVA in size are powered by the likes of Lister Petter and Kohler engines and used for all matter of commercial, industrial and rural power requirements.

    All Gentech/Dunlite products are backed by comprehensive warranties from the manufacturer (Welling & Crossley) and come with national service agent and spare parts support. Thanks. 

  • Do the Gentech Generators use Genuine Honda Engines?

    Hi Glen, thanks for your question. The answer is a definite yes! The Gentech Petrol Generators use 100% authentic Honda engines purchased from Honda Australia. The engines come with a full 4 year commercial warranty on their GX model engines, along with a 2 year generator warranty for frame, alternator etc. You can have the engine serviced or inspected by any approved Honda service agent around the country - there are more than 400 accredited service agents.

    We are aware of some cheaper brands using imported "Honda" engines in generators and other power equipment which are not authentic engines from Honda Australia. We do not stock any products that use non-verified Honda engines. Gentech have over 20 years of Australian Generator experience and along with Dunlite and Powerlite, they are one of our best-selling portable trade generator brands. They are built in Australia and designed for longevity and to handle demanding working environments.

    Cheers, Steve



  • Do you have a link to the wheel kit for the 3 phase 12.5KVA and the 16 KVA Gentech? If I buy the wheel kit, do you fit it? Does the genny have a handle? How much for Delivery?

    Hi - here is a link to the manufacturer's page for the wheel kit: Gentech DGX06 Large Wheel Transportation Kit 

    The generator cant be shipped with the wheel kit attached, it will come separately but there are pre-drilled holes for easy fixing to the generator. 

    This unit does not come with a handle. Some manufacturers have health and safety restrictions on such fittings for units over a certain size. With the wheels fitted, these units are easy to  maneuver.

    For delivery, simply enter your postcode into the Shipping Calculator located on the product page. You can choose from home delivery or local depot pick up.

    Thanks, Steve

  • Will this run Inverter Welders?

    Depending on the size of the welder you wish to run, then yes.  The fact the welder is an "Inverter" wont affect this generator or your welder.

    The inverter welder means it will regulate the power it receives, plus they don't make inverter style generators in 3 phase or in the larger 8kva+ style generators.

    They do make smaller inverter generators for camping/recreation, but you won't be able to run a welder off them, as they are too small in power out put.

  • What size 3 phase motor could this unit continually drive?

    Hi - you'd just need to know how much power (in Watts) your motor draws at start up and when running. This generator produces 12,500 watts at start-up and 9,600 watts continuously. Thanks
