The DuroMax XP11000iHT Delivers 11,000 Peak Watts of Quiet Tri-Fuel Inverter Power
The DuroMax XP11000iHT Tri-Fuel Portable Inverter Generator gives you clean sine wave power on gasoline, propane or natural gas. Its 459cc DuroMax engine produces 9,000 running and 11,000 peak watts on gasoline, 8,550 running and 10,450 peak watts on propane and 7,700 running and 9,500 peak watts on natural gas.
It runs at 61 dB at 25% load with less than 3% total harmonic distortion, and includes a 50A outlet for generator interlocks and transfer switches. Remote start, CO Alert shutdown, parallel capability, DC output and a 5-year DuroMax warranty round it out.


DuroMax XP11000iHT Features
Tri Fuel Technology
Run on gasoline, propane or natural gas. A 15-foot, 1/2-inch natural gas hose with quick-connect fittings and a 4-foot propane hose with regulator are included. Natural gas operation requires 6.0 to 9.0 inches of water column and up to 204,000 BTU at full load.
Quiet, Clean Sine Wave Power
Total harmonic distortion under 3% protects computers, TVs and appliance electronics. Demand-based variable idle keeps it at 61 dB at 25% load.
Home Backup Ready
A 14-50R 50A outlet and an L14-30R 30A outlet connect to interlocks and transfer switches. Four 5-20R GFCI household outlets cover everyday loads.
Remote and Push Button Start
Start with the included remote control or the push button, with a recoil starter as a backup. The AGM battery and included battery tender keep it ready.
CO Alert Shutdown
A built-in sensor shuts the generator down if carbon monoxide builds to unsafe levels around the unit.
Parallel Capability and DC Output
Pair it with another compatible DuroMax inverter (sold separately) for more power. DuroMax also lists DC output for charging 48V and 52V battery banks.
Long Runtime
The 7.1-gallon tank delivers about 18 hours at 25% load and 9 hours at 50% load on gasoline. On propane at 50% load, DuroMax rates about 8, 12 and 20 hours on 40, 60 and 100 lb tanks.
Real-World Applications
Home backup on natural gas. Connected to a gas line, run essential circuits through long outages without refueling.
Homes with sensitive electronics. Clean power protects computers, routers and HVAC controls.
Battery bank charging. Use the DC output to recharge compatible 48V or 52V battery systems.
RVs. Quiet operation suits campgrounds, and the outlets connect to RV service with the right cord or adapter.
How It Compares to Common Alternatives
Versus the DuroMax XP11000iH. The iH has the same gasoline and propane output without natural gas operation.
Versus the DuroMax XP13500iHT. The XP13500iHT adds 1,500 running watts on gasoline and a larger 8-gallon tank.
Versus open-frame tri-fuel generators. The XP11000iHT runs quieter with cleaner power, at a higher price per watt.
Is the XP11000iHT the Right Fit
-
California. It is EPA certified but not CARB certified, so it is not available for sale in California.
-
Natural gas output. Running output drops to 7,700 watts on natural gas, so size your loads for the fuel you plan to use.
-
Weight. At 216 lbs dry, it rolls on its wheel kit.
-
Connections. Use a licensed electrician for the interlock or transfer switch and a qualified gas professional for natural gas.
This may be a good fit if
- You have a natural gas line and want quiet backup power
- You want clean power for electronics
- You want remote start and a 50A outlet
Common Questions
