    The spec says 110V single phase for the input, so I should be okay.
    It does also say 50Hz, and I am in the USA and use 60Hz, but the supplier said it was compatible.

    That is what is advertised, is it on the Nameplate of the VFD Drive

    50Hz or 60Hz is just the default of the VFD Drive it has nothing to do with your power supply frequency

    If you check a 220v 3Kw VFD you will see it has the same 13A rating for your 110v to be 3Kw it would have to be 26A so what you will be getting is a 220v VFD Drive which may be labeled 110v
