1750 VA - that's not very big. That will only supply about 3A at your
rated 575V. By the time you derate and other losses in your VFD you
will only be able to drive about a 1hp motor continuous. 100%
efficiency you would be at 2 1/4 hp motor, but you are going to have a
lot of losses, plus I wouldn't want to be driving the transformer and
VFD that hard anyways. Not sure what startup currents would do to this
system.
