FAQ
Can the XP11000iHT power my entire house?
The XP11000iHT provides 11,000 peak and 9,000 running watts, which is enough to power refrigerators, central air conditioning, a water heater, lights, and other essential appliances simultaneously. For whole-home backup, you'll want to calculate your total power needs and connect via a transfer switch or interlock kit installed by a licensed electrician. The included 50 Amp NEMA 14-50R outlet makes this straightforward with most standard home backup setups.
What fuels does it run on, and is natural gas hookup easy?
The XP11000iHT runs on gasoline, propane, or natural gas - you can switch between them using the front-panel fuel switch. Natural gas hookup is made easy with the included 15-foot x 1/2-inch natural gas hose with Quick Connect fittings. For propane, the included regulator and standard flare fitting connection works with most propane tanks (40 lb minimum recommended). Simply select your fuel source on the panel and you're ready to go.
Is this generator safe for sensitive electronics like laptops and TVs?
Yes. The XP11000iHT is an inverter generator, which means it produces a pure sine wave output with Total Harmonic Distortion (THD) under 3%. This is cleaner power than most household utility connections and is safe for laptops, smart TVs, medical equipment, and other sensitive devices. Traditional open-frame generators produce "dirty" power with much higher THD that can damage sensitive electronics over time.
How loud is the XP11000iHT?
At 25% load, the XP11000iHT operates at approximately 61 dB - roughly equivalent to a normal conversation. The demand-based variable idle control also lowers the engine speed automatically when the load decreases, so it gets even quieter when you're not drawing full power. This makes it significantly quieter than open-frame generators of similar wattage, and suitable for use in residential areas and campgrounds.
Does it require assembly? How is it shipped?
The generator arrives mostly assembled - the wheel and handle kit is included and attaches easily. It ships via freight with free liftgate and curbside delivery included. Due to its 258-lb shipping weight, you'll need assistance moving it from the delivery point into your home or storage area. Adding oil before first use is required, and the included oil funnel makes this simple. Full setup instructions are in the owner's manual included in the box.
Can I connect two XP11000iHT units together for more power?
Yes - the XP11000iHT supports parallel capability, allowing you to pair it with another compatible DuroMax inverter generator (sold separately) to double your available power output. This is ideal for applications where you need more than 11,000 watts but want the portability and fuel efficiency of inverter technology rather than a single large open-frame unit.
