Meanwell sine inverter--information needed

It's a TS-1000-124A, a "true sine", 120VAC 1000W output, 24VDC input:

I'm looking for a schematic of this or other Meanwell sine inverter.



Anyone familiar with how similar these Meanwell sine inverter input voltage stages are (rectification & input to the "chopper")? Would a 24VDC unit work on 12VDC? Or might these boards be made for several DC voltages and populate (or not) certain components?



I don't have the unit but am contemplating that it may somehow be useful on



12v, maybe derated.

Thanks.

The data sheet states that the under-voltage shutdown for the 24V model is at 21V +/- 4%. The de-rating graph indicates that the maximum load is reduced by 20% at 21V. So it is very unlikely that it will be useful at 12V, even if modified to bypass the under-voltage shutdown.

Why not buy one of the 12V models?
