DuroStar Diesel generator.
I think it was 6000w continuous and 7200 peak at least.
OK, a link:
I think DuroStar is out of the diesel business, too many failures?
I almost bought a used military surplus unit for $2,000 that would have ran the entire neighborhood
It was rated 25,000 watts nominal, meaning it can go lots higher!
It had a user-adjustable governor, meaning it could be over-revved and make more power at a higher frequency. Or go “canadian” at 3000 RPM (50 hz) if you wish!
The main drawback to that unit is that it weighed 1500 pounds.
But the fuel usage was about ½ of a portable diesel uses to produce a KW. Well worth it if you want to have a permanently installed unit.
