11 reviews for SG7500K – 7500/9375 Watt Tri Fuel Portable Generator with Kohler Engine

  1. Mark – Greensboro NC

    The TriFuel SG7500 is a great generator, with an unlimited supply of fuel from my natural gas meter! The generator and accessories shipped promptly, and set up was straight forward with no surprises. This generator supplies more than enough power to run my HVAC , refrigerator and house lights. It runs very clean and I literally cannot smell any exhaust. From inside the house, I can notice it running, but it is not intrusive. The GenTent allows low cost all-weather portability.”
