what options have i got guys?

cant send it back.....

havnt got 3 phase

Looked at inverters and rang a few places but they keep saying i need to wire it do the motor, problem is it has a basic computer that gets power from somewhere so need that to work too. The computer has a note saying use 240v fuse but does that mean it will be single phase? so can wire seperate?

Every company i rang, i said "can i not have single phase in to your inverter,then the output of the inverter wire to the mains power socket of the machine", but they say no?????????
