I'm still not getting it...
So, your motor and generator can provide 2000 W...
This 2000 W is available to power the inverter and charge the batteries...
The inverter is 90% efficient...
If it is consuming the entire 2000 W available then at 90% efficiency it is only making 1800 W for the mining rig.
the generators power output is rpm dependent basically the faster you spin it the more the power it produces.
so at peak rpm at 24 volts it would produce 2000 watts if you convert watts to amps that would give approximately 83 amps of output power.
if you ran 2 generators in parallel you would produce the same 24 volts but now 2 times the amperage or 2000 + 2000 is 4000 watts / 24 volts
=about 166 amps. we would then have 166 amps of charge power at 24 volts to charge the battery bank the battery bank is used to power the power inverter.
without going into detail about my knowledge or what i do for a living i can tell you this does and will work.
