31kw back up generator, can be wired in and/or used as standalone power, set up w 2 240 outlets and 4 120 outlets. There is an option to have this put on a small trailer to make it a portable power unit for an additional charge which can be discussed. Currently it is configured in Single Phase 31kw, but it can very easily be switched to 3 phase 40kw with a switch on the AVR and switching a couple of wires.It was gone thru by Emerson & Matkin out of Pocatello as they specialize in Detroit Diesel Engines. After it was gone thru it never got installed, but Emerson came down and started it, but its sat so it will need fuel filters and belts. If I replace the price will go up as these units sell for over 20k. Have service manual and books associated with the unit that were $450 alone and have all the Service and Repair Information as well as parts list with part numers. $10000 obo. Partial trades possible but cash is king. Currently sitting on a trailer so delivery is possible but may be extra depending on mileage. Will need equipment capable of picking up atleast 2500lbs. Its on skids also. Call or text 208-591-0075
