And the paired 3kw units have an effective 50 amp service plug. Hell, my entire house runs on a 60 amp service. What are you talking about 'too small'?
I think your technology is dated and you need to study up on modern inverter tech.
A 12 or 24VDC genset feeding an inverter can make any kind, frequency, or phase AC that you care to specify. I can get 400hz, 3 phase, 480VAC out of inverters that stack nicely. At respectable power levels, like 30kW.
An inverter doesn't care about whether the power comes from solar panels, or an alternator.
And Honda married an alternator and a modern inverter.
No-one has used banks of capacitors for phase regulation in years. Or motor driven inductors for that matter. Or even sync-selsyn equipment.
The F-16 does still have a motor generator for some of the 400Hz ac stuff, but solid state is taking over.

Johnny, would you mind posting your crepe recipe using powdered eggs?
