Description

Zoom on the Genmax GM10500iETC

In a nutshell, the Genmax GM10500iETC is a powerful portable inverter generator mostly geared towards:

  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Camping and tailgating buffs looking to enhance their experience

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed.

Power & Run Time

The Genmax GM10500iETC in use

The Genmax GM10500iETC

The Genmax GM10500iETC delivers 120/240V and is equipped with a tri-fuel technology, enabling it to operate on gasoline, propane, or natural gas. When powered by gasoline, it achieves a running wattage of 8,500W and a peak wattage of 10,500W. Switching to propane provides 8,000 rated watts and 9,500 peak watts, while natural gas operation delivers 6,800W of rated wattage and 8,400W of starting wattage. Additionally, as the generator is parallel capable (GM9000PK parallel kit (opens in a new tab) not included), it can be linked to a second unit for more power.

The inverter generator, rated for a noise of 64 dBA (just slightly more noisy than an office), provides flexibility in starting, offering both a manual recoil starter system and a practical and straightforward electric starter (battery included). Additionally, the GM10500iETC may be remotely started, enhancing user convenience (key fob included).

Concerning its running time, the GM10500iETC, featuring a 6.9 gallons fuel tank, can continuously run for up to 14 hours with a full gasoline tank (consuming fuel at approximately 0.49 gallons per hour). Alternatively, when utilizing propane, it offers up to 7 hours (estimation based on a 20 lbs tank - propane consumption around 0.67 GPH) of runtime.

The <3% Total Harmonic Distortion (THD) of the GM10500iETC ensures a clean sine wave output, providing a secure power source for your sensitive electronics through its AC outlets.

Outlets

The control panel is equipped with the following 6 AC outlets:

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

Moreover, it comes equipped with 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle making battery charging a breeze.

With its twist-lock L14-30R receptacle, the GM10500iETC is configured to be transfer switch ready, allowing straightforward connection to your breaker box to supply backup power to your home during outages. The unit also features an ATS plug, which makes it compatible with automatic transfer switches.

Portability

With its enclosed inverter generator design (L30.9 x W22.6 x H29.3 in), the Genmax GM10500iETC offers superior aesthetics and operates with minimized noise levels, distinguishing itself from standard, open frame generators. The design follows the contemporary trends and is perfect for recreationally generating power.

Even at 244.7 lbs, the generator is categorized as 'portable,' suggesting its movability, although its weight impede its portability. Despite the restricted maneuverability, its set of 2 wheels and its folding handle provides a solution, allowing for convenient shifting once the generator is positioned on the ground.

Features

Panel of the Genmax GM10500iETC

The GM10500iETC's control panel

Embedded in the control panel of the GM10500iETC, a digital data center serves as a vital feature, offering comprehensive information on the voltage, power output, lifetime run hours and frequency to aid in monitoring activity and status. To offer you even more control and easy operation during nighttime, the panel is LED-lit.

In addition to this info, the generator's light indicators provide visual feedback when its oil levels are insufficient, the generator is on overload and the generator is ready.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the inverter generator.

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, 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.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Genmax GM10500iETC also comes with several accessories, including: key fob, battery charger, funnel, RV adapter, neutral bonding plug, natural gas hose with NPT adapter, tool kit, cover and propane hose.

The Genmax GM10500iETC versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Genmax GM10500iETC compare to multi-fuel generators of similar power (between 8000 and 9000 W).

  • With a weight of 244.7 lbs, the Genmax GM10500iETC is notably on the heavier side among multi-fuel generators in the 8000-9000 rated wattage range. If weight is an important consideration for you, the Pulsar PGL9000BCO stands out as one of the top contenders in this power category, with a dry weight of 149 pounds.
  • With a lowest noise rating of 64 dBA, the inverter generator is one of the more quiet of the generators of similar type and power. If noise emissions are one of your priorities, you may be interested in the DuroMax XP11000iH, one of the least noisy generators similarly powerful as this one, rated for 61 dBA.
  • In terms of autonomy, the GM10500iETC offers up to 14 hours at a 25% load, placing it at the lower range within its type and power range. If prolonged run time is essential to your needs, you could consider the DuroMax XP10000HX, which offers one of the highest autonomy among devices with similar power output, lasting up to 22 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank's capacity and thus, doesn't say much on its own unless we consider fuel consumption as well. This inverter generator doesn't excel in fuel efficiency when compared to others of its kind: it consumes approximately 0.49 GPH at a 25% load. If fuel consumption is your top priority, we suggest to check out the DuroMax XP10000HX, which has a fuel consumption of only 0.38 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 8000-9000W multi-fuel generators, the Genmax GM10500iETC is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
