Probably your waveform is nothing like sinusoidal.

Why would you expect this ? A generator is an electromagnetic machine
with a great big iron core. There's little in there to cause harmonics
and there's a great bit LR filter to damp them out. Inverters are your
culprits for angular waveforms, not electrical machines.

In my almost negligible experience, flicker from generators has usually
been caused by switching in crude electromechanical regulators.
