It's close, but there's a "fudge factor" which should be taken into account here. With any systems, you need to add a percentage for loss, slop, inefficiency, etc. An efficient inverter draws the load, plus whatever energy it takes to make it run (between 10% & 20% depending on the type). Any time you are figuring on wires, loads, current, use, etc. I would add about 25% for the "slop factor" in the system. Always better to have it & not need it than need it and not have it.
Conversions from one voltage to another always seem to draw a bit more than we think.
