Our take on the DuroMax XP28000iHT Tri-Fuel 22000W/28000W Portable Inverter Generator

The DuroMax XP28000iHT is a tri-fuel portable inverter generator built for whole-home backup. Its 999cc engine makes 22,000 running and 28,000 peak watts on gasoline, dropping to 20,000/25,000 watts on propane and 16,000/20,000 watts on natural gas. Total harmonic distortion stays under 3%, so it can feed sensitive electronics and central air, and 2-wire start lets a compatible solar inverter run it automatically. It is one of the few inverter generators at this output, and it costs far more and weighs far more than the 10-12 kW tri-fuel portables most homeowners buy.

About the DuroMax XP28000iHT Tri-Fuel 22000W/28000W Portable Inverter Generator

The DuroMax XP28000iHT is a portable inverter generator that runs on gasoline, propane or natural gas. Its 999cc engine produces 22,000 running and 28,000 peak watts on gasoline. On propane it produces 20,000 running and 25,000 peak watts, and on natural gas 16,000 running and 20,000 peak watts. Total harmonic distortion stays under 3%.

It has two 14-50R 50A outlets, an L14-30R outlet and four 5-20R GFCI outlets. The 50A outlets can be used with interlocks or transfer switches. DC output charges 48V and 52V battery banks, and 2-wire start lets a compatible solar inverter start and stop the generator automatically through its dry contacts.

You can start it with the included remote or the push button. A built-in sensor shuts the generator down if carbon monoxide builds to unsafe levels. An AGM battery and an included battery tender keep it ready to start. It has a bonded neutral, so check compatibility with your transfer switch with an electrician. A qualified gas professional should confirm that your meter and line can supply the natural gas it needs at full load.

Questions and answers

How much power does it make on each fuel?
Gasoline gives 22,000 running and 28,000 peak watts. Propane gives 20,000 running and 25,000 peak. Natural gas gives 16,000 running and 20,000 peak.
Can it run my central air conditioner?
On gasoline, 22,000 running watts is enough for central air plus a water heater and well pump in many homes. On natural gas the 16,000 running watts leaves less headroom, so add up your surge loads first.
What does 2-wire start do?
It connects to the dry contacts on a compatible solar inverter, which can start and stop the generator on its own when battery power runs low.
What comes in the box?
A 15-foot 3/4-inch natural gas hose with quick-connect fittings and a 6-foot propane hose with regulator are included, along with remote start.
Is it safe for electronics?
Yes. Total harmonic distortion stays under 3%, which is clean enough for computers, TVs and other sensitive devices.
Is it really portable?
It has wheels and a handle, but at this output class it is a heavy unit. Plan on a permanent spot with a transfer switch rather than moving it often.
