OK, this is really on topic.
I have a chance to obtain a 20 KW AC generator 'head' at a cool price.
Specs read 120/240 60 Hz 1 phase
Speed is 1800 rpm
Also it is NIB! (and $150)
I have 2 options, trailer mount it and run from my PTO or set it up in a dedicated fashion.
It so happens that I own a 16HP Wisconsin that is idle so that would be my option. (has starter and 12 generator built in)
What I don't know is the accepted HP to KW ratio generally accepted
Either set up will need some reduction* but that I can handle.
Actually both my PTO and Stationary engine are close in HP ratings.
*would reduction not also improve functionality as torque would increase.
Presently I use a 6000 watt genset and it is installed up to code so I'd be partially done, plus that is in a small shed adjacent to my service entrance.
Sure would be nice to have heaters and hot water during outages, and we average more than normal being in the boonies at the end of the road.
(LOL, shucks 8 years ago I was donated an ONAN diesel that would have been the perfect match but that got traded away for something more useful at the time.)
