DuroMax XP28000iHT 28,000W Tri Fuel Portable Inverter Generator with CO Alert


Description

The DuroMax XP28000iHT is a powerhouse tri fuel inverter generator delivering up to 28,000 peak watts and 22,000 running watts - enough to back up an entire home with ease. Engineered for homeowners, contractors, and anyone who needs serious, reliable power, this generator runs on gasoline, propane, or natural gas, giving you the flexibility to use whatever fuel is available. Its inverter technology produces clean sine wave power with less than 3% total harmonic distortion, making it safe for sensitive electronics like laptops, smart TVs, and medical equipment.

The XP28000iHT is built for convenience as much as capability. Variable speed demand-based idle control keeps noise down and fuel consumption efficient at partial loads, while push-button and remote start mean you never have to struggle to get it running. With dual 50-amp outlets, a 2-wire solar start interface, and a 48V/52V DC output for charging battery banks, this generator bridges the gap between portable power and a permanent home backup system.


Key Features

  • 28,000 Peak / 22,000 Running Watts (Gasoline): Enough power for whole-home backup including A/C, refrigerators, lights, and more simultaneously.

Manuals & Guides

FAQ

Can the XP28000iHT power my entire house?

The XP28000iHT provides 28,000 peak watts and 22,000 running watts on gasoline - enough for most whole-home backup needs including refrigerators, air conditioning, lighting, and other appliances simultaneously. For whole-home connection, you will need a transfer switch or interlock kit (sold separately). DuroMax recommends hiring a licensed electrician for installation. Check the combined wattage of your essential appliances before purchasing to confirm compatibility.

How does the tri fuel system work - can I switch fuels while it's running?

The XP28000iHT features a front-panel fuel selector switch with GAS, LPG, and NG positions. While it is best practice to switch fuels while the generator is off or at idle to avoid stalling, the selector makes transitioning between fuel types straightforward. The generator includes a propane hose and regulator as well as a 15-foot natural gas hose with quick connect fittings so you can hook up to either fuel source right out of the box.

Is this generator safe to use with sensitive electronics like computers and TVs?

Yes. As an inverter generator, the XP28000iHT produces a clean sine wave with total harmonic distortion (THD) of less than 3%. This is comparable to - or better than - the power from your home's utility grid, making it completely safe for laptops, desktop computers, televisions, medical equipment, and other sensitive devices.

What is the 2-Wire Start feature and how does it work?

The 2-Wire Start allows the generator to connect directly to a solar inverter's dry contact terminals. When your battery bank drops below a set threshold, the solar inverter sends a signal through the dry contacts that automatically starts the XP28000iHT. Once the batteries are charged, the inverter signals the generator to shut off. This creates a seamless, automated backup charging system without any manual intervention.

How is this generator delivered, and does it require assembly?

The XP28000iHT ships via freight with free liftgate and curbside delivery to the 48 contiguous U.S. states - it will be placed at your driveway or curb. At 466 lbs, you will need assistance moving it into position. Assembly is minimal: add the recommended oil (10W-30), connect your fuel source, and it is ready to start. The included Owner's Manual walks through the initial setup process step by step.

Does the CO alert actually shut the generator off automatically?

Yes. The built-in CO sensor continuously monitors carbon monoxide levels in the generator's vicinity. If CO accumulates to a dangerous threshold, the generator automatically shuts itself off and alerts you - no manual intervention required. This is an important safety feature, though it does not replace the fundamental rule of always operating any generator outdoors and away from windows, doors, and vents.
