I have never seen a vfd that you connect up to a 240v single phase supply to 415v three phase, I am a industrial engineer and have never come across one, I am sometimes wrong though! The only thing I have come across to power up single phase to 415v three phase is a phase converter, there are two types, a static variety which is not a true three phase supply, or a rotary variety which uses motors to generate a three phase supply.
But a vfd? I don't think they exist.
