The DuroMax XP13500iHT Delivers 13,500 Peak Watts of Clean Tri-Fuel Inverter Power
The DuroMax XP13500iHT Tri-Fuel Portable Inverter Generator gives you flexible backup power on gasoline, propane or natural gas. Its 550cc DuroMax engine produces 10,500 running and 13,500 peak watts on gasoline, 10,000 running and 12,750 peak watts on propane and 9,000 running and 11,500 peak watts on natural gas.
Clean sine wave power with less than 3% total harmonic distortion, a 50A outlet for interlocks and transfer switches, remote start, CO Alert shutdown and DC output make it a well-rounded home backup generator. It is backed by a 5-year DuroMax warranty.
DuroMax XP13500iHT Features
Tri Fuel Technology
Run on gasoline, propane or natural gas. A 20-foot, 1/2-inch natural gas hose with quick connect and a 4-foot propane hose with regulator are included. Natural gas operation requires 6 to 9 inches of water column and up to 225,000 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 66 dB at 25% load and saves fuel at light loads.
Home Backup Ready
A 14-50R 50A outlet and an L14-30R 30A outlet connect to interlocks and transfer switches. Two 5-20R GFCI 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.
DC Output
DuroMax lists DC output for charging 48V and 52V battery banks, and DC output wires are included.
Long Runtime
The 8-gallon tank delivers about 19.9 hours at 25% load and 10.8 hours at 50% load on gasoline. On a 40 lb propane tank, DuroMax rates about 16.9 hours at 25% load and 9.2 hours at 50% load.
Real-World Applications
Home backup on natural gas. Connected to a gas line, run essential circuits and in many homes, central air, through long outages.
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 and job sites. Connect to 50A RV service, or run tools with stable power.
How It Compares to Common Alternatives
Versus the DuroMax XP13500iH. The iH has the same gasoline and propane output without natural gas operation.
Versus the DuroMax XP11000iHT. The XP13500iHT adds 1,500 running watts on gasoline and a larger tank.
Versus the DuroMax XP13000HXT. The open-frame HXT costs less. The XP13500iHT runs quieter with cleaner power.
Is the XP13500iHT the Right Fit
-
California. It is EPA certified but not CARB certified, so it is not available for sale in California.
-
Outlets. It has two 5-20R outlets, fewer than some larger DuroMax models, so plan cords for plug-in loads.
-
Weight. At 234 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 want clean tri-fuel inverter power for home backup
- You have a natural gas line and want long runtimes
- You want remote start and a 50A outlet
