I’m a little confused on what a victron auto transformer does. Does it only turn 120 into split phase 240 or does it also turn 12v into 240. Would I need a inverter to feed the auto transformer? If so it sounds like a lot of efficiency loss.
Thank you
First, the Autotransformer only deals with AC current. So yes, you will need an inverter - ideally for your whole rig.
Second, autotransformers are incredibly efficient - in the high 90s, up to 99%. You will find the overall system, with a quality inverter, far more efficient than the rooftop unit you are looking to replace.
Finally, it's by far the cleanest solution as it will allow you to run a 240V AC unit both disconnected, and when plugged in to single phase 120V electrical sources, directly from the source rather than always using your inverter.
