I recently sold my old 1.8KW Latronics LF inverter (it was 24V version) but before the buyer came I looked at its waveform with my little kit oscilloscope and a 1200W load (fan heater) on the inverter.
Its output was pretty wobbly, a fair bit worse than the output of my home built 3KW inverter with the same load. My inverter showed little difference from the idle wave form, which I think is pretty good.
So, this commercial unit is not perfect either.
