Paul, I found Virtaucompany [which google] on e-bay US, selling a 13kw unit with PTO drive and gear-box, giving 50A x 240v, @ about £800+ ship. taxes etc. The problem is the PTO's 540 rpm, requiring a g/box of 3-1 on a 1500 rpm alternator or 6-1 on a 3000rpm unit, making a home-build very difficult.
