TV on Inverter 2000w VS 300w Draws
Tested for this with each inverter clamped to battery bank in turn, 32" TV, and Trimetric for volts and amps. 300w- off: 12.6v, 00.2a on: 12.6v, 00.5a TV on: 12.5v , 9.2a (climbing slowly with "...

The msw inverters will generally be more efficient on some loads as there is just a lot less components. To get an apple to apple comparison both inverters should be of the same type. I would also rerun the test with a 100 watt light bulb. Tvs can draw different currents depending on the picture being displayed.

Yes, TV draw depends on the picture brightness selected--the brighter the higher the draw. In the OP test, the TV stayed the same.
If the MSW would be more efficient, that just makes the PSW 2000w inverter in the OP look better I think.
I do have a 3000w MSW in the attic somewhere I could try. It has a display panel though, showing watts draw and battery volts, so that would add a little to the "on" draw I suppose. Might get at that later
