Tri Fuel Inverter Generators
Tri Fuel Inverter Generators: Maximum Fuel Flexibility, Clean Power
A tri fuel inverter generator combines three fuel options, gasoline, propane, and natural gas, with the stable, clean output of inverter technology, giving you both flexibility and power quality in a single unit. This DuroMax lineup ranges from the XP7000iHT at 7,000 watts up to the XP28000IHT at 28,000 watts, covering everything from moderate home backup to serious whole-home or job site power, all with the fuel independence that matters most when a single supply chain becomes unreliable during an extended outage.
Why Three Fuel Options Matter
Unlike a dual fuel unit limited to gas and propane, a tri fuel inverter generator adds natural gas as a third source, which means that if you have a gas line at your property, you gain what's effectively an unlimited fuel supply as long as utility gas service continues. This matters most during the kind of extended outages that follow major storms, when gas stations run dry and propane suppliers can sell out days after landfall. Being able to fall back to a home's natural gas line removes that fuel-availability risk entirely.
Sizing from the XP7000iHT to the XP28000IHT
The XP7000iHT suits moderate home backup or job site use where 7,000 watts covers the expected load. The XP11000iHT steps up for larger households or heavier equipment demands. At the top of the range, the XP16000iHT and XP28000IHT deliver enough continuous output for whole-home coverage or demanding commercial and industrial applications, while still producing the clean, stable power inverter technology provides across the entire lineup.
Frequently Asked Questions
Is it worth paying more for tri fuel over dual fuel if I don't have natural gas at home?
If you don't have a natural gas line and have no plans to install one, the added cost of tri fuel capability may not deliver much practical benefit, since you'd realistically only ever use the gas and propane options anyway. Tri fuel makes the most sense specifically for buyers with existing natural gas service who want that fallback option available, rather than as a general upgrade for everyone regardless of their home's utility setup.
Does running on natural gas reduce output compared to gasoline?
Yes, most tri fuel generators, including this DuroMax lineup, produce somewhat less output on natural gas or propane compared to gasoline, typically a reduction in the range of 10 to 20 percent. This is worth factoring into your sizing decision, since a unit rated at 16,000 watts on gasoline may deliver noticeably less once switched to natural gas, so buyers planning to rely on natural gas as their primary fuel should generally size up rather than buying to the exact wattage they expect to need.
Can two of these tri fuel inverter units be connected together for more power?
Several DuroMax inverter models support parallel operation with a compatible parallel kit, allowing two units to combine output for more total power than either could deliver alone. This lets buyers start with a smaller, more portable unit like the XP7000iHT and add a second later rather than immediately committing to a larger single generator. Not every model in the lineup necessarily supports parallel connection, so confirming compatibility between two specific units before assuming they can be paired is worth doing.
