Quality of AC power output

Has anyone tested an EB200 or similar with an oscilloscope to determine how clean the AC output is?

I have tested the output from my EB3A (with no load) and it looks like a perfect sine wave on the scope. better then grind Power.

I know not very scientific.

From what I’ve read, it seems that the waveform distorts to some extent as the load is increased to near the limits of the device. Makes me wonder how it looks during a high amp start up (a fridge or AC compressor, for example).

Thanks for the reply.

Thanks for the video. Do I have this correct: the better waveform on top is from the Bluetti and the irregular one on the bottom is from the mains? If so it looks like the Bluetti handles the 10A load quite well.
