Cummins Onan P11000iTF 11,000W Tri-Fuel Inverter Generator

Cummins Onan P11000iTF 11,000-Watt Tri-Fuel Inverter Generator

The Cummins Onan P11000iTF gives you the fuel flexibility people actually need when the power is out. Run it on gasoline, propane, or a properly sized natural gas supply, then switch fuels with the front-mounted selector. You get 120/240-volt power, a 50-amp receptacle, clean inverter output, and three starting methods in one enclosed portable generator.

This is a strong fit for home backup, large RVs, mobile work, and storm preparation. It has enough gasoline output to cover serious loads, but it is still designed to be moved with an integrated wheel kit and lockable folding handle. The remote key fob is especially useful when the generator is positioned safely outside and away from doors, windows, and vents.

Why the P11000iTF stands out

• Three fuel choices: gasoline, propane, or natural gas
• Up to 11,000 peak watts: substantial output for home, RV, and jobsite loads
• Clean inverter power: total harmonic distortion of 3% or less
• 120/240V capability: includes 30A and 50A receptacles
• Remote, electric, and recoil start: start it the way that works best for the situation
• 64 dBA rated sound level: enclosed inverter design for quieter operation
• CO safety shutoff: carbon-monoxide detection automatically stops the engine when unsafe levels are detected
• Onboard information display: monitor output, voltage, fuel level, remaining runtime, and lifetime hours
• Transfer-switch ready: suitable for connection through properly installed manual transfer equipment

Power output by fuel

Best uses

• Home outage backup: refrigerators, freezers, lights, pumps, communications, and selected household circuits through approved transfer equipment
• Large RVs and fifth wheels: 50-amp 120/240V connection and enough output for demanding camping loads
• Hurricane and storm preparation: choose the fuel that is available instead of depending on gasoline alone
• Remote properties: useful where propane storage or an existing natural gas connection makes more sense than frequent refueling
• Jobsites and mobile service: 120V and 240V receptacles for tools, equipment, chargers, and temporary power

Frequently asked questions

Can the P11000iTF run on natural gas?

Yes. Natural gas is one of its three factory-supported fuels. Natural-gas output is 8,800 peak watts and 7,200 running watts. The fuel supply and hose must be correctly sized for the installation.

Does it produce 240-volt power?

Yes. The generator provides 120/240V output through both a 30A L14-30R receptacle and a 50A 14-50R receptacle.

Is the power safe for electronics?

The inverter system is rated at 3% total harmonic distortion or less, making it suitable for many modern electronics and appliances when used within the generator's capacity.

Can it back up a house?

It can supply selected home circuits when connected through code-compliant manual transfer equipment installed for the application. Never connect a portable generator directly to household wiring or a utility service without approved transfer equipment.

Will it start remotely?

Yes. A remote key fob is included, with a rated operating distance of up to 98 feet. Push-button electric start and recoil start are also provided.

Can I use it at high altitude?

Operation above 2,000 feet requires the appropriate Cummins high-altitude carburetor and fuel-switch kits. Engine output normally decreases as elevation increases.

Is this model CARB compliant?

No. This is an EPA 49-state model and is not for sale in California.

Safety note: Operate outdoors only, far from doors, windows, vents, and occupied spaces. Follow the Cummins manual and local electrical, fuel-gas, and fire codes. A licensed professional should size natural-gas piping and install any home transfer equipment.
