Description

Zoom on the Genmax GM6250iET

To sum up, the Genmax GM6250iET is a compact portable inverter generator tailored for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in outdoor fairs, festivals or events
  • Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals in need of safely powering high-intensity work or lighting equipment

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.

Power & Run Time

The Genmax GM6250iET delivers 120/240V and benefits from a tri-fuel technology that allows it to run on gasoline, propane, or natural gas. When gasoline-powered, it enjoys a running wattage of 5,500W and a peak wattage of 6,250W. When propane-powered, it benefits from 5,000 rated watts and 5,500 peak watts. Its natural gas operation offers 4,500W of rated wattage and 5,000W of starting wattage. In addition, the parallel capability (parallel kit not included) empowers increasing of power output when linked to another similar or compatible unit, ensuring expanded energy capacity and reliability for various applications.

The inverter generator, rated for a noise of 66 dBA (less noisy than a normal conversation), provides flexibility in starting, offering both a conventional pull-start mechanism and a hassle-free and practical electric starter (battery included). The GM6250iET can also be remotely started, offering further convenience (key fob included).

In terms of its run time capability, the GM6250iET, furnished with a 3 gallons fuel tank, can maintain operations for up to 10 hours on a full tank of gasoline (with fuel consumption averaging 0.3 gallons per hour). It also provides up to 11 hours (estimation based on a 20 lbs tank - propane consumption around 0.43 GPH) of operation with propane.

The GM6250iET produces a clean sine wave: thanks to a <3% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel is equipped with the following 4 AC outlets:

Duplex 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120/240V 50A (14-50R) receptacle

Furthermore, it has 2 DC outlets: there's two 5V USB ports (1 x USB-A and 1 x USB-C) with which charging of electronics like mobile phones and tablets is made convenient.

If you own an RV with a 50-amp service, you can consider this Genmax unit as RV-ready, as it features a 14-50R outlet. Its L5-30R receptacle can also be used for a simple RV connection with an L5-30P to TT-30R adaptor. In addition, the unit features an ATS plug, which makes it compatible with automatic transfer switches.

Portability

Thanks to its closed inverter generator design (L22.8 x W17.8 x H19.7 in), the Genmax GM6250iET not only offers superior aesthetics but also operates with reduced noise levels compared to a typical, open frame generator. The design follows the contemporary trends and is perfect for recreationally generating power.

Since the generator weighs 102.6 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Despite the restricted maneuverability, its set of 2 wheels and its telescopic handle provides a solution, allowing for convenient shifting once the generator is positioned on the ground.

The GM6250iET's control panel

Enhancing monitoring capabilities, the GM6250iET features a digital data center within its control panel, furnishing essential details on the frequency, power output, fuel level, lifetime run hours and voltage for tracking activity and status.

In addition to this info, several light indicators serve to show you when the generator is on overload, the generator is ready and the oil level is too low.

From a security standpoint, the generator is furnished with an automatic low oil shut-off and an overload protection (circuit breaker), ensuring peace of mind during operation.

It also benefits from Genmax's CO DETECT technology, which is designed to monitor the level of carbon monoxide present during the generator's operation. If the generator is positioned incorrectly and carbon monoxide levels rise to an unsafe level, the generator will automatically shut down.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Genmax GM6250iET, the following accessories are also included: cover, funnel, tool kit, battery charger and key fob.

Genmax App

Generator stats on the Genmax app

The app allows remote monitoring

Genmax’s app lets you pair your smartphone with your GM6250iET inverter generator. It allows you to always know exactly what is going on.

Using Bluetooth technology, the generator communicates with the app (available on iOS (opens in a new tab) devices) to conveniently monitor power consumption, fuel level, remaining runtime, and even remotely shut off your generator directly from your smartphone.

The information displayed within the app is identical to the information displayed on the LCD screen of the GM6250iET.

The Genmax GM6250iET versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Genmax GM6250iET compare to inverter generators of similar power (between 5000 and 6000 W).

  • Concerning weight, the Genmax GM6250iET weighs only just 102.6 pounds, distinguishing itself as one of the lighter inverter generators amidst the 5000 to 6000 rated wattage range. If weight matters to you, one of the champions in this power range is the Pulsar PGX60BiSRCO with only 93.5 pounds.
  • In comparison to generators with a similar running wattage, this inverter generator's lowest emitted noise of 66 dBA can be considered noisy. If you value reduced noise levels, the Honda EU7000iS could be worth considering. It's one of the quietest generators in its power range, rated at 52 dBA.
  • Regarding its autonomy, the GM6250iET can run for up to 10 hours at a 25% load, aligning it with the lower performers in its type and power range. If prolonged run time is essential to your needs, you could consider the Champion 201532, which offers one of the highest autonomy among devices with similar power output, lasting up to 18 hours.
  • Run time is a key metric, but it's dependent on the generator's fuel capacity. Therefore, discussing fuel efficiency is necessary to get the full picture. This inverter generator has an average fuel consumption among comparably powerful devices, as it reaches 0.3 GPH (gallon per hour) at a 25% load. To prioritize fuel savings, we advise considering the DuroMax XP7000iHT, which stands out for its gasoline efficiency, consuming just 0.19 gallons per hour.
