yes,
The 8010 or 002 would do fine, the pj would require some modding/deception to get it to run at a voltage other than designated.
Probably the 8010 would be the best, as it is easy to customise, and little to go wrong.Fair chance the normal governor would do fine for the job if just pure sine was the goal.... but if you want slow motor on low output, then yes a controller would need to be fashioned.
The older reliable cap field gennies need higher rpm... so they would not do unless you only wanted clean power.
Units with AVR would probably still need a fair rpm to keep them stable, as if you let the rpm drop too much, you may burn out the rotor or the rotor drive coils in the stator........
I don't know what sort they use for the normal units doing this.
For home brew, would probably go for a HV car alternator style of device in that case... ie the usual AVR type of 240v alternator......voltage does not matter so much then, so we can use the field for our purposes.
I could effect output by rpm and field winding. You would be surprised at how much current can be developed at reasonably low rpm with just a car alt and a controller .. ie at little more than an idle you can still get 40 amps if you drive the field on most cars hard..... so I would go that style ( 48v), and gear it up if no AVR sort handy, so that most times I was at low speed for most of the power range, and only ramp rpm up if I was pushing it hard.... then back off field as rpm rose.... so nano or similar so decisions can be made..... certainly doable via analog too.
With the transformer, drive voltage is just a side issue... what ever transformer we have and we can accommodate it.
By using field and rpm for power control, I expect it would be pretty stable.
Just off the top of my head anyway.
edit... actually. in my journals somewhere, there are descriptions of avr units I repaired/rewound, and also motor car alternator sets i built.... they both lend themselves to this project.... particularly the car alt sets. you can do without a controller for them, they run low speed anyway, and the govenor controls the motor as the regulator does it's thing.
In truth, I would not bother... more solar and no generator is my motto.... and I'm further south than you...... and for a genny, a 5hp honda and a few 48v alternators would do in a pinch.
Co-generating is pointless if your transformer is big enough, as keeping the fets cool is easy enough at high power from my experience so far.
