Megawatt Inrush And Small Generators
In the interests of accuracy I have copied John Marles, comments verbatim and they appear below "Inrush is 50A/115VAC 50A/230VAC for a few milliseconds on the S-400 and S-350. Its controlled by due...

But it sure do affect power draw. Small generators are really touchy about horsepower/watt curves meaning horsepower implies speed. Hah! If a Harbor Freight 700 watt generator had a three pound flywheel* this wouldn't even be an issue :)
*In addition to the rotor.
I fitted a 108 lbs flywheel to my Kubota for exactly that reason. When I visited Transamericad delaval in Oakland, their 8-cylinder 17,000 hp engines spun a 6-1/2 ton flywheel. I was around 19-years of age accompanying my father. The engineer spoke words of inertial mass kinetics vs engine speed slump and recovery time. Old radar-ears here, sucked it up.
Wide-eyed I watched another massive engine reverse rotation. The engine spun down to 0 RPM pneumatic servos pushed (or pulled) twin camshafts, the engine continued for 3 cycles then reversed. Not the generator engine. If it has a catwalk, it is a big engine.
