Hi wanting to know from practical experience, what the minimum power is to drive an ST 10 type gen head, and get decent output? (at least 7-8kw)
I have seen you tube videos with s195 type engines but most are rated at 13.2 hp @2000 rpm, and i wondered if this was sufficient.
One my be available at a very reasonable price, in stead of a 5k version. That 13hp would most definitely drive.
By my math 742 watts per horse power, 10000watt generator 742 watts per horsepower about 13.4 hp.
Or do i have this completely wrong.

Hi OSM, yes they should be a fair match. It is always better to have an alternator head that will stall an engine than to have an engine that would keep going and burn out a smaller head. Just be careful with the difference between run current on equipment and start up current. A motor may pull only 1 amp while running but could pull ten while starting up.
