Some manufacturers will suggest a de-rating factor, I have used the Mitsubishi 1.5kw for 2hp motors for some time and not had a problem, the VFD also controls the accel/decel so the the inrush is different than starting a motor across the line, the VFD parameters limit things like maximum current etc, DC braking etc.
