Don, I don't have a big enough inverter generator to give details of the sneeze. I can offer the following startup comparisons of a very strong shore power connection vs. the Onan, shore power first:
Even though this is a "big picture" shot there are a few details that can be gleaned. Notice how the sampled waveform is so much smoother with the shore power. That's because of the "kinda sorta" sine wave output of a small AVR generator. An inverter generator picture would be closer to the shore power picture. Also, even though the RMS voltage is the same for both, the Onan's peak voltage is higher due to the imperfect waveform, and also the RMS current is 22% higher. I conclude from this that without the good sine wave expected from an inverter generator, the air conditioner could draw 22% more power. But I'm digressing. The Onan's voltage drop looks really good, and the initial surge clears just as fast as it does on shore power.
