Hi Brett,
I operate an opal mine north of Lightning Ridge.
I use a 7000 watt diesel generator for my setup. It is a twin cylinder Ruggerini motor with a Dunlite alternator. It is air cooled and weighs around 100kg.
I would recommend you go to the Dunlite webpage and have a look.
I have had a cheep Chinese generator before and I would not have one ever again.
My Generator cost around $7000 give or take a few hundred. I figured it is worth paying for something reliable especially when you are out in the bush.
It has not missed a beat.
One thing to be mindful of, make sure the generator has a minimum 30% loading when it is running. If you run a diesel generator without load, the cylinders will glaze and the unit will not last very long.
If I am not using the generators full capacity, I run a 2000 watt motor to load it up.
Cheers
Phil
