Description
Zoom on the DuroMax XP28000iH
In a few words, the DuroMax XP28000iH is a powerful portable inverter generator perfectly suited for:
- Professionals in need of safely powering high-intensity work or lighting equipment
- Small homeowners in search of a full power backup solution
In the upcoming sections, you'll discover its power characteristics, the array of outlets it presents, its overall portability, and the additional features it possesses.
Power & Run Time
The DuroMax XP28000iH
The dual-fuel technology of the DuroMax XP28000iH allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 22,000W and a starting wattage of 28,000W. If propane-powered, it gives 20,000 rated watts and 25,000 starting watts. The impressive running wattage makes this unit one of the biggest inverter generators currently on the market.
Rated for 70 dBA (just as noisy as a shower), the inverter generator's starting mechanism relies on a practical and straightforward electric starter (battery included). Additionally, the XP28000iH features remote starting, offering users increased convenience (key fob included).
The unit also features 2-wire start capability, allowing connection to compatible automatic transfer switches (ATS), solar battery systems, or hybrid inverter setups through a low-voltage contact-closure control interface.
As for its running time, the XP28000iH, along with its 12.7 gallons fuel capacity, can run for around 9 hours at 50% load with a full tank filled with gasoline (fuel consumption around 1.41 GPH). If propane is used, it can operate for around 3.3 hours (on a 20 lbs tank - propane consumption around 1.42 GPH).
Featuring a <5% Total Harmonic Distortion (THD), the XP28000iH delivers a clean sine wave, guaranteeing the safety of your sensitive electronics plugged into its AC outlets.
Outlets
The control panel features the upcoming 7 AC outlets:
In addition, it provides 1 DC outlet: there's a 48-58V 10A output to charge your home backup Li-ion batteries.
Since it features a twist-lock L14-30R receptacle, the XP28000iH is tailored to be transfer switch ready, making it easy to connect it to your breaker box for home power support during outages.
Portability
With its enclosed inverter generator design (L39.3 x W31 x H34.5 in), the DuroMax XP28000iH offers superior aesthetics and operates with minimized noise levels, distinguishing itself from standard, open frame generators. This modern design aims to provide an ideal power solution to recreational users.
With a weight of 466 lbs, the generator is still labeled as 'portable,' denoting its ability to be moved, although its heaviness might restrict easy portability. Nevertheless, the restricted maneuverability is counteracted by its set of 4 wheels and its folding handle, enabling easy shifting once the generator is set in place.
Features
The XP28000iH's control panel
The XP28000iH's control panel is equipped with a digital data center, furnishing detailed information on the frequency, lifetime run hours, voltage and power output for you to easily track its activity and status.
In addition to this info, light indicators on the device will signal if the oil level is too low, the generator is overloaded and the generator is ready.
The built-in fuel gauge of the inverter generator ensures simple and quick gas level assessments.
In terms of security, the generator features an overload protection (circuit breaker) and an automatic low oil shut-off, ensuring peace of mind during its 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.
In addition to the traditional documentation and an owner's manual (opens in a new tab) to help you get started promptly, the DuroMax XP28000iH also includes several accessories: funnel, battery charging cables, propane hose, tool kit, key fob and battery charger.
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 in at 466 lbs, the DuroMax XP28000iH fits within the expected weight range for devices producing 14000 to 22000 rated watts. If weight is a key factor for your needs, the Pulsar PGD170TiSRCO is noteworthy for being one of the top contenders in this power range, with a dry weight of 313 pounds.
- This inverter generator offers a rated noise level of 70 dBA, placing it among the quieter alternatives in its power category. If you are concerned with noise, check out the Pulsar PGD170TiSRCO, which is one of the least noisy generators in its power range, with a noise rating of just 66 dBA.
- The XP28000iH's autonomy is somewhat low end compared to devices of its power range, as it reaches only around 9 hours at 50% load on a full tank. If prolonged run time is essential to your needs, you could consider the Westinghouse WGen20000, which offers one of the highest autonomy among devices with similar power output, lasting around 11 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This inverter generator has an estimated fuel consumption of roughly 1.41 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. 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.
