I've got a Hatz Diesel 2KW generator
set I brought back from Germany
when I was there. It was built for the German Army. It's all self contained and in a box that sound proofs it pretty well, about as loud as a motor
home generator. It's 2KW at 220V so I think that with a step down transformer it's a 4KW. It starts like an old Model T car, with a hand crank, a compression
release is used until you get it spinning and them the exhaust
valve is allowed to function, without the compression
release it would be a real bear to start. All the small Diesels are a bear to start in real cold weather
as there are no glow plugs. Great little generator, only problem is with the box and all, it weighs I think 100kg, 220 lbs.
