Cummins 11kW Portable Generator The Cummins 11kW portable generator delivers reliable power when you need it most. The tri-fuel capability and inverter technology provides clean, efficient power for your home, RV, or jobsite. The Onan P11000iTF runs on gasoline, propane, or natural gas, offering maximum fuel flexibility to meet your specific needs. Powerful Cummins Onan Engine The powerful 457cc Cummins Onan OHV four-stroke engine provides reliable power with flexible fuel options. This extensive engine runs at 9kW on gasoline, 8.1kW on propane, and 7.2kW on natural gas. Surge capacities of 11kW, 10kW, and 8.8kW make it possible to start large items like A/C units while the generator continues powering other items. The variable-speed engine automatically adjusts to match the current power demands, optimizing fuel efficiency and running the generator as quietly as 64dBA. Tri-Fuel Flexibility An incorporated dial makes it easy to switch between the three different fuel types. This flexibility allows you to fuel your lifestyle with the most economical option. When running on gasoline, the 7.4 gallon tank provides up to 16.5 hours at 25% load. The same load provides up to 6.7 hours when connected to a 20lb propane tank or up to 50 hours when connected to a natural gas line. Simply stop the generator at 50 hours for maintenance and then continue powering your devices with natural gas. Clean Power for Sensitive Electronics As an inverter generator, the P11000iTF produces clean, stable power with less than 3% total harmonic distortion, a measurement of voltage and frequency fluctuations. This makes it perfect for sensitive electronics like computers, medical equipment, and modern appliances. Digital Data Center Enables Easy Monitoring The integrated Digital Data Center displays essential information like remaining runtime, power output, voltage, frequency, fuel level, and lifetime run hours. This user-friendly diagnostics system helps you monitor generator performance and plan refueling, ensuring uninterrupted power for your home or jobsite. Multiple Starting Options Start the generator three ways: with the push button start, with the included remote keyfob, or with the backup pull cord. The electric start and remote capability make operation convenient, while the recoil backup ensures you can always start the generator when needed. Safety Features Safety is paramount with all Cummins products, and this includes the P11000iTF. The built-in carbon monoxide detector continuously monitors CO levels and automatically shuts down the generator if it detects dangerous levels. Low oil shutdown protects the engine, while circuit breaker overload protection safeguards your connected equipment. A spark arrestor enables safe operation in fire-prone areas. Portable Design Despite its power, this generator remains easily portable. The foldable, locking handle and included 8-inch wheel kit simplify transportation. At 219lbs dry weight, the cantilevered handle allows two people to easily move the generator. Operation and Maintenance The P11000iTF functions without additional components at elevations below 2,000ft. Elevations above 2,000ft require an additional High Altitude Carburetor Kit and Fuel Switch Kit. The Cummins generator ships with additional tools for easy maintenance. Upkeep is straightforward with items from your local hardware store like SAE 10W30 oil. Warranty and Support Backed by a 3-year limited residential warranty (1-year commercial), the Cummins Onan P11000iTF is EPA certified and built to professional standards. Cummins’ extensive engine expertise and manufacturing quality ensure reliable operation for years. Choose the Cummins 11kW portable generator for versatile, reliable power that adapts to your specific fuel availability and power requirements.
