Zoom on the Genmax GM9000iED
In summary, the Genmax GM9000iED is a powerful portable inverter generator especially useful for:
- Food truck owners who do not wish to see their business interrupted under any circumstances
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Camping and tailgating hobbyists looking for a portable power source
- Professionals in need of safely powering high-intensity work or lighting equipment
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
Power & Run Time
With its dual-fuel technology, the powerful and versatile Genmax GM9000iED provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 7,600W along with a peak wattage of 9,000W. While propane-powered, it provides 7,200 rated watts and 8,550 starting watts. In addition, as it is parallel capable (GM9000PK (opens in a new tab) not included), this power can be increased when linked to another similar or compatible unit.
Enjoying a noise rating of 62 dBA (just slightly more noisy than background music), this inverter generator can be started thanks to a simple traditional pull-start mechanism, but also to a convenient and easy-to-use electric starter (battery included). Moreover, to offer you even more convenience, the GM9000iED can also be remotely started (key fob included).
The GM9000iED, with a fuel capacity of 6.9 gallons, reaches a run time of up to 14.5 hours utilizing gasoline (fuel consumption around 0.48 GPH). Alternatively, it can reach a run time of up to 7 hours (estimation based on a 20 lbs tank - propane consumption around 0.67 GPH) with propane.
Sensitive electronics can be safely plugged in the AC outlets, as the GM9000iED produces a clean sine wave, with a <3% Total Harmonic Distortion (THD).
The control panel features the following 6 AC outlets:
Additionally, it features 2 DC outlets: there's two 5V USB ports (USB-A) allowing you to conveniently charge electronics such as mobile phones and tablets.
Since the GM9000iED bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.
The Genmax GM9000iED 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.
Since the generator weighs 243.6 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). 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.
A digital data center, one of the features of the GM9000iED's control panel, gives you information on the power output, voltage, frequency and lifetime run hours, and thus, is helpful for the monitoring of its activity and status.
In addition to this info, some light indicators allow you to instantly see if the generator is ready, its oil levels are insufficient and the generator is on overload.
The inverter generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.
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.
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Genmax GM9000iED also comes with some accessories: key fob, funnel, propane hose and tool kit are included.
The Genmax GM9000iED is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
However, it features a spark arrestor and therefore, can be used in forested areas.
In addition, the unit meets the ANSI/PGMA G300-2018 safety and performance requirements.
The Genmax GM9000iED versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Genmax GM9000iED compare to dual fuel generators of similar power (between 7500 and 8500 W).
- As its dry weight is 243.6 pounds, the Genmax GM9000iED is one of the heavier of the dual fuel products which can generate 7500 to 8500 running watts. If weight is your top priority, one of the champions in this power category is the Cummins Onan P9500df, weighing just 194 pounds.
- 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 type and power.
- Autonomy-wise, with up to 14.5 hours on a full tank at a 25% load, the GM9000iED is on the low end when compared to other dual fuel generators of a similar power output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the DuroMax XP10000HX, boasting with up to 22 hours.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. 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 fuel consumption is your top priority, we suggest to check out the DuroMax XP9000iH, which has a fuel consumption of only 0.35 GPH and thus, is one of the most efficient devices in our database.
As you can see from these interactive charts, when compared to other 7500-8500W generators, the Genmax GM9000iED 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.

Trying to understand whether I am going to have an issue running home backup when I don't know whether I need bonded or floating ground. I have read that either will work as long as the house plug (15-50) is not GFCI protected. Can you confirm the 14-50 plug is not GFCI protected? Any other relevant info would be helpful. (Asked July 12, 2022)
Only the 5-20R receptacles are GFCI protected.
