I don't think that would produce the consisent voltage that he would require. Now for an outdoor application you can get an old lawnmower and rig it up to an alternator. It would be very loud but that will work.
It won't run 2000W on that psu. You can get a portion of that but not 2000W RMS. Do you know how to wire it up? Ground the light green wire. Get another black and I think yellow for 12v.
