DuroMax XP11000iH 11,000 Watt Dual Fuel Portable Inverter Generator
Description
The DuroMax XP11000iH delivers 11,000 peak watts of clean, quiet inverter power from a single portable unit built for whole-home backup. Running on either gasoline or propane, it gives homeowners and professionals the fuel flexibility to stay powered through any outage or emergency. With less than 3% Total Harmonic Distortion (THD), this generator produces clean sine wave power that is safe for sensitive electronics like computers, medical equipment, and smart appliances. A 50-amp outlet makes it fully compatible with generator interlocks and transfer switches, so connecting it to your home's electrical panel is straightforward.
At just 61 dB at 25% load, the XP11000iH runs quietly enough to have a conversation nearby - a major advantage over conventional generators of similar capacity. Whether you're weathering a storm at home, powering a remote jobsite, or heading out in an RV, this generator is engineered to handle the demands of real-world use with reliability and ease.
Key Features
- 11,000 Peak Watts / 9,000 Running Watts (Gas): Enough power to run central air conditioning, a water heater, refrigerator, and more simultaneously during an outage.
- Dual Fuel Technology: Runs on gasoline or propane - switch fuels even while the generator is running. Propane offers a longer shelf life and cleaner burn than gasoline.
- Low THD (<3%): Clean sine wave inverter output protects sensitive electronics, computers, and medical devices from power fluctuations.
- 61 dB at 25% Load: Whisper-quiet operation compared to conventional generators - ideal for residential neighborhoods and campsites.
- 50-Amp Outlet (NEMA 14-50R): Home backup ready - compatible with interlock kits and transfer switches for whole-home power.
- Remote Start Included: Start your generator from inside your home during a storm without going outside.
- CO Sensor Shutdown: Automatically shuts the generator off when dangerous carbon monoxide levels are detected, keeping your family safe.
- AGM 12V Battery: Delivers longer lifespan and enhanced cold-weather starting performance compared to standard batteries.
- Parallel Capability: Pair with a second compatible DuroMax inverter (sold separately) to double your power output.
- DC Output (58V): Charge 48-56V battery banks including solar and Powersports batteries directly from the generator.
- 100% Copper Windings: More efficient power transfer and greater long-term durability than aluminum-wound alternatives.
- 5-Year Warranty: Backed by DuroMax's USA-based support team and nationwide network of service centers.

FAQ
Can this generator power my entire home during an outage?
Yes - the XP11000iH is specifically designed for whole-home backup power. With 9,000 running watts on gasoline and a 50-amp outlet compatible with interlock kits and transfer switches, it can handle central air conditioning, a water heater, refrigerator, lights, and more simultaneously. The exact load will depend on your specific appliances, so it's a good idea to add up your appliance wattages before connecting.
Is the power safe for sensitive electronics like TVs, computers, and medical equipment?
Yes. The XP11000iH is an inverter generator with less than 3% Total Harmonic Distortion (THD), which means it produces clean sine wave power equivalent to what comes from your home's wall outlets. This makes it safe to use with laptops, televisions, CPAP machines, and other sensitive electronics that can be damaged by the "dirty" power produced by conventional generators.
How does the dual fuel system work, and can I switch fuels while running?
Yes - the XP11000iH features a front-facing fuel selector switch that lets you change between gasoline and propane even while the generator is running. Simply connect your propane tank to the included 4-foot hose and regulator, or fill the 7.1-gallon gasoline tank. Propane is a great choice for long-term storage scenarios since it doesn't degrade on the shelf the way gasoline does.
How quiet is the XP11000iH compared to other generators?
At 61 dB at 25% load, the XP11000iH is significantly quieter than conventional open-frame generators of similar wattage, which typically run at 70-76 dB or higher. For reference, 61 dB is roughly the volume of a normal conversation. The demand-based variable idle feature also reduces engine speed - and noise - whenever the connected load is low.
Does this generator require assembly, and how is it shipped?
The XP11000iH ships via freight with free liftgate and curbside delivery - a delivery driver will bring it to the curb of your address. At 226 lbs, it includes a wheel and handle kit to help you maneuver it into position. Minimal setup is required: add the included oil, connect the battery tender if needed, and you're ready to start. Full instructions are in the included Owner's Manual.
What is the CO Sensor Shutdown feature and why does it matter?
The built-in CO (carbon monoxide) sensor continuously monitors CO levels around the generator. If dangerous concentrations are detected - which can happen if the unit is placed too close to a structure or in a partially enclosed space - the generator will automatically shut itself off before harmful levels accumulate. This is a critical safety feature, as CO is odorless and colorless and can be lethal. Always operate the generator outdoors, away from windows and doors.
Can I connect two of these generators together for more power?
Yes. The XP11000iH includes a parallel connector port on the front panel. With a compatible parallel kit (sold separately), you can connect two XP11000iH units together to combine their output for significantly more power. This is a great option if your needs grow or if you want a redundant power setup.
