The general rule to remember is that a frequency inverter can convert single phase into three phase power but, it cannot provide a higher voltage out than what you put in. Therefore if you only have a 220V 1phase power supply input, you cannot get three phase 415V output. It will only provide 220V 3 phase output. If you have a 480V power supply you can output three phase 415V a lower voltage.
