Description
Zoom on the DuroMax XP28000iH
In a few words, the DuroMax XP28000iH is a powerful portable inverter generator perfectly suited for:
- Professionals who want to ensure that a power failure will not prevent them from working
- Small homeowners in search of a full power backup solution
Over the following sections, you'll uncover its power characteristics, the selection of outlets it offers, its overall portability, and the supplementary features it includes.
Power & Run Time
The DuroMax XP28000iH
Featuring dual-fuel technology, the DuroMax XP28000iH provides 120/240V, and offers both power and versatility. Running on gasoline, it delivers a running wattage of 22,000W and a starting wattage of 28,000W. When propane-powered, it offers 20,000 running watts and 25,000 starting watts. The impressive running wattage makes this unit one of the biggest inverter generators currently on the market.
The inverter generator features a straightforward and intuitive electric starter (battery included). It is rated for a noise of 70 dBA (just as noisy as a vacuum cleaner). Additionally, the XP28000iH may be remotely started, enhancing user convenience (key fob included).
The generator also supports 2-wire start, enabling integration with compatible automatic transfer switches (ATS), solar battery systems, or hybrid inverter setups via a low-voltage contact-closure control circuit.
The running time of the XP28000iH, with its 12.7 gallons fuel capacity, can reach around 9 hours at 50% load on a full tank of gasoline (fuel consumption around 1.41 GPH). With propane, it can reach around 3.3 hours (on a 20 lbs tank - propane consumption around 1.42 GPH).
The XP28000iH generates a clean sine wave with <5% Total Harmonic Distortion (THD), ensuring minimal electrical noise and fluctuations. This feature makes it ideal for powering sensitive electronics, providing stable and reliable AC power through the outlets.
Outlets
The control panel features the upcoming 7 AC outlets:
It also sports 1 DC outlet: there's a 48-58V 10A output to charge your home backup Li-ion batteries.
Because the XP28000iH is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.
Portability
With an inverter generator design, the DuroMax XP28000iH features a closed construction (L39.3 x W31 x H34.5 in), enhancing aesthetics and ensuring reduced noise levels, offering a distinct advantage over standard, open frame generators. The generator has a contemporary design, convenient for recreationally generating power.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 466 lbs make may make it challenging to manually lift and transport. However, its challenging mobility is solved by its set of 4 wheels and its folding handle, which will ease its displacement, once it is on the floor.
Features
The XP28000iH's control panel
With a digital data center integrated into its control panel, the XP28000iH provides real-time insights into the frequency, voltage, power output and lifetime run hours, enabling easy monitoring of its status and activity.
In addition to this info, several light indicators serve to show you when the generator is on overload, the generator is ready and its oil levels are insufficient.
With its built-in fuel gauge, the inverter generator provides quick and convenient gas level checks.
From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.
The XP28000iH also benefits from DuroMax’s CO Alert carbon monoxide shutdown. If CO levels become unsafe or rapidly increase, the generator will automatically shut down, an indicator will light red, and the engine will not restart for 5 minutes.
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the DuroMax XP28000iH also comes with some accessories: key fob, battery charger, propane hose, battery charging cables, funnel and tool kit are included.
The DuroMax XP28000iH versus other generators
The following charts are provided to give you an idea of how some of the key specs of the DuroMax XP28000iH compare to generators of similar power (between 14000 and 22000 W).
- Weighing 466 lbs, the DuroMax XP28000iH is one of the heavier generators within the 14000-22000 rated wattage bracket. Weight-conscious users may find the Pulsar PGD170TiSRCO appealing, as it is one of the top contenders in this power range, weighing just 313 pounds.
- With a lowest noise rating of 70 dBA, the inverter generator is one of the more quiet of the generators of similar power. For those who are looking for a less noisy device, we suggest the Pulsar PGD170TiSRCO. With just 66 dBA, it is one of the most quiet devices in this power range.
- Regarding its autonomy, the XP28000iH can run for around 9 hours at a 50% load, aligning it with the lower performers in its power range. If runtime is a priority for you, the Westinghouse WGen14500DFc stands out as one of the generators with the longest run time in its power range, providing around 11 hours of continuous use.
- Run time is a key metric, but it's dependent on the generator's fuel tank capacity. Therefore, discussing fuel efficiency is necessary for a complete understanding. The inverter generator utilizes approximately 1.41 GPH of gasoline at a 50% load, placing it within the typical range of fuel consumption seen in products of comparable wattage. If fuel consumption is your top priority, we suggest to check out the Westinghouse WGen14500DFc, which has a fuel consumption of only 0.95 GPH and thus, is one of the most efficient devices in our database.
Price comparison
As you can see from these interactive charts, when compared to other 14000-22000W generators, the DuroMax XP28000iH is on the expensive side of the price range.
While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.
