Yanmar 6.5kVA Portable Diesel Generator, Reliable as Anything! Tired of generators that crack the sads the minute things get a bit rough? The Yanma...
View full detailsWhen the job needs diesel that starts and stays on, Yanmar generators are framed machines for the site, the shed, and a proper backup load. Long run times, without the fuss of a petrol top-up every few hours.
Read moreThis range is diesel, not a suitcase inverter. Yanmar engines are built to hold a steady load and sip fuel while they do it. Compact framed units cover tools and a light backup circuit. Larger ones take pumps, lighting, and a heavier site day. Single phase covers the usual outlets. Three phase covers workshop and pump gear. Mine-spec versions add the protection a mine site asks for. Heavy-duty frames are there when the machine lives in the weather and on the move.
If diesel is the whole brief, the wider category is diesel generators. For site work that has to meet a mine spec, see generators for mining. If the house is the job, read our guide to diesel generators for home backup.
The compact end of diesel generators from Yanmar. Enough for grinders, lights, a small pump, and a few power points. Easy to move, diesel economy when the day runs long, and electric start so you are not standing over a cold engine.
The heavy end of Yanmar generators. More outlets, more starting capacity, and three phase where the workshop or the pump needs it. Heavy-duty units are the ones you leave on the job. Mine-spec versions are for sites that ask more of the frame, the controls, and the way the machine is protected. If the brief is keeping the house alive rather than running the site, start with generators for home backup and size from the circuits you will actually run. A transfer switch or inlet, fitted by a licensed electrician, is the safe way to feed the board. Never backfeed a socket.
A mine-spec unit is built for sites that ask more of the frame, the shutdowns, and the way the machine is protected than a standard worksite generator. It is still a Yanmar diesel generator. It is not automatically the right pick for a shed or a house. If the site has a written spec, match the listing to that spec, or call us and we will check it with you.
Both use a Yanmar diesel engine. A standard unit is the framed machine for tools, a pump, and a normal site day. A heavy-duty Yanmar generator is the one you leave on the job, moved often, and run harder. If the generator lives in the weather or gets thrown in the ute every week, take the heavy-duty frame. If it sits in a shed and comes out for outages, the standard unit is usually enough.
Only if the gear you are running is three phase. Workshop machines, some bore pumps, and some welders need it. Lights, a fridge, and ordinary power tools do not. A single phase Yanmar generator will not run three phase equipment, no matter how many watts it has. If you are not sure what the pump or the machine wants, check the data plate before you buy.
Diesel is the better engine when the load stays on. A Yanmar diesel generator sips less fuel under a steady load than a petrol unit doing the same job, and it is happier sitting on power for hours. Petrol is easier for short, stop-start work and a quiet campsite. If the day is lights, a pump, or site gear from morning to knock-off, diesel is the point of this range.
Yes, if the generator can cover the starting surge, not just the running watts. Pumps and compressors draw a lot more for a few seconds than they use once they are going. Write down the motor size and whether it is single phase or three phase, then match a Yanmar diesel generator with headroom. A unit that only matches the running watts will bog down on start and may shut down.
Size a Yanmar diesel generator to what will actually be on at once, and to the starting surge of the pump, not the running watts alone. Lights, a fridge, and a few power points often sit on a mid-size single phase unit. Add a bore pump, an air conditioner, or three phase workshop gear and you need the listing that covers that motor and that phase. A transfer switch or inlet, fitted by a licensed electrician, is the safe way to feed the house. Never backfeed a socket.
Check the oil before every start. After the first few hours on a new Yanmar diesel, change the oil, then follow the manual for oil, air filter, and fuel filter intervals. Use clean diesel and do not leave old fuel sitting for months, or the next start is a filter job. Keep the battery charged on the electric-start units. Do not leave it idling for hours with almost no load. A diesel likes a real load, and light load all day can glaze the bore.
