Description

Zoom on the Genmax GM9000iE

In a nutshell, the Genmax GM9000iE is a powerful portable inverter generator mostly geared towards:

  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Camping and tailgating hobbyists looking for a portable power source
  • Professionals who want to ensure that a power failure will not prevent them from working

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Genmax GM9000iE in use

The Genmax GM9000iE

The Genmax GM9000iE houses a 458 cc Dinking OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 7,600W along with a peak wattage of 9,000W. Moreover, since it is parallel capable (GM9000PK (opens in a new tab) not included), its power may be increased if linked to a second compatible unit.

The inverter generator features a simple traditional pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 62 dBA (just slightly more noisy than background music). The GM9000iE can also be remotely started, offering further convenience (key fob included).

The fuel capacity of 6.9 gallons allows the GM9000iE to operate for up to 14.5 hours with a full tank (fuel consumption around 0.48 GPH).

The GM9000iE 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 features the upcoming 6 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle
120/240V 50A (14-50R) receptacle

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

Because the GM9000iE 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

The Genmax GM9000iE is an inverter generator and has an encased design of the following dimensions: L30.9 x W22.6 x H29.3 in. Thus, it is more aesthetical than conventional, open frame products. This modern design aims to provide an ideal power solution to recreational users.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 233.7 lbs make it incredibly difficult to manually lift and transport. However, its challenging mobility is solved by its set of 2 wheels (⌀7") and its folding handle, which will ease its displacement, once it is on the floor.

Features

The GM9000iE's control panel

One of the many GM9000iE's features is the data center, included in its control panel, which conveniently provides information on the voltage, frequency, power output and lifetime run hours and thus, helps you monitor its activity and status.

In addition to this info, some light indicators allow you to instantly see if the generator is overloaded, its oil levels are insufficient and the generator is ready.

The fuel level of the inverter generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

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. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Genmax GM9000iE also comes with some accessories: funnel, key fob and tool kit are included.

Emissions

The Genmax GM9000iE is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor, so it is adequate for use in forested areas.

In addition, the unit meets the ANSI/PGMA G300-2018 safety and performance requirements.

The Genmax GM9000iE versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Genmax GM9000iE compare to generators of similar power (between 7500 and 8500 W).

  • A weight of 233.7 lbs makes the Genmax GM9000iE one of the heavier devices in the 7500-8500 rated wattage range. In terms of weight, one of the champions in their power range is the Dewalt DXGNR8000, standing at just 183 lbs.
  • As its lowest possible noise is rated at 62 dBA, this inverter generator qualifies as one of the most quiet of the products of similar power.
  • As for its autonomy, the GM9000iE, with an autonomy of up to 14.5 hours at a 25% load, is placed on the low end among the generators of its kind. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the DuroMax XP9000iH, with up to 20 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This inverter generator is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.48 GPH at a 25% load. If you wish to further improve in the area of fuel efficiency, the DuroMax XP9000iH, which boasts with a gas consumption of only 0.35 GPH, may be the right generator for you.

Price comparison

As you can see from this interactive chart, when compared to other 7500-8500W generators, the Genmax GM9000iE 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.

    I love everything about this generator but….it keeps shutting down when the load on the indicator gets up to 4k watts. It’s advertised to be 9000 peak 7600 running, but that’s not happening for me….Would appreciate any help here…

    + PROS:
    • Price,
    - CONS:
    • keeps shutting down when the load on the indicator gets up to 4k watts
