Features for the Generac GP15000E

The Generac GP15000E generator combines more power with the convenience of portability. 15,000 running watts and 22,500 starting watts are ideal for larger applications, either at home or on the jobsite. Equipped with low-oil shutdown keeps your engine safe, while the hardened steel tube cradle protects the machine in rougher environments. Plus with a 10 hour run time at 50% load, you'll have plenty of power all night long.

  • Generac OHV Engine: A long-life Generac OHV engine with full pressure lubrication lasts 3-4 times longer than competitive generator engines.
  • Electric Start: The electric start option gets you up and running, fast.
  • Idle Control: Lowers noise levels and increases fuel efficiency for long run-times.
  • Low-Oil Shutdown: Monitors oil pressure and automatically shuts down the engine if low oil is detected.
  • Large Fuel Tank: 16 gallon fuel tank with built-in fuel gauge gives you up to 10 hours of run time at 50% load.
  • Hardened-Steel Tube Cradle: Durable and rugged cradle frame prevents the generator from damage.
  • Circuit Breaker Protected Outlets: Protects your generator against a circuit overload.
  • Portability: Wheel kit, lifting eye, fixed handles, and pneumatic tires make transporting easy in the most rugged conditions.

My second machine. 1st one lasted 15 years. I ordered the new one from Jack’s. I figured it would take a week or so to get to me since I live in South Florida. Two days later I was being contacted for the delivery by the freight company. The product showed up with no damage, on a wooden pallet, with the cardboard packaging all intact. could not have asked for a better or easier purchase.

Staff very helpful (Linda Brannon) and professional. Very large and heavy item (Generac GP15000e generator) arrived in perfect condition. Delivery made easy because of Ms. Brannon's assistance. Delivery driver brought the item via hand truck down my driveway and put it where we wanted it. This is the second item purchased from Mowers at Jacks and the first very large item. Would recommend them for all your needs.
