I have one of those chinese UPower split phase 18000w pure sine wave inverters. It'll do 3000w all day. I notice as you load it, the 60hz noise gets louder from the transformer vibrating.
If I load it and run a separate 100a charger though, I am noticing an irregular pulsing of transformer noise. I haven't plugged an oscilloscope on it while it is doing it. Is it because of harmonic interference? Likely the charger is just a switching dc power supply running at 100-300khz. Can it cause harm?
