The generator must deliver the starting current with the minimum variation of the voltage frequency and drop voltage.

So, the power of the generators depends also on the acceleration ramp and the current limitation set in the ATV.

The current harmonics overheat the generator windings because the RMS current is higher compared to a sinus current. Because of that, a line choke is helpful.

Generally for the generator, 2 times the motor power is generally enough.
