Description

Zoom on the Genmax GM15000ET

To sum up, the Genmax GM15000ET is a powerful portable generator tailored for:

  • Professionals who want to be able to deliver results, even during a power failure
  • Homeowners in need of an emergency backup power for their essentials

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 Genmax GM15000ET in use

The Genmax GM15000ET

The Genmax GM15000ET delivers 120/240V and boasts with a tri-fuel technology enabling it to utilize gasoline, propane, or natural gas. When powered by gasoline, it achieves a running wattage of 11,000W and a peak wattage of 15,000W. Upon using propane, it gains 10,000 rated watts and 13,000 peak watts. Its operation with natural gas provides 8,800W of rated wattage and 12,000W of starting wattage.

Operating with a noise rating of 76 dBA (less noisy than a dishwasher), this generator offers two starting options: a standard recoil pull-rope starting mechanism and a simple and elegant electric starter (battery included). For additional convenience, the GM15000ET may also be remotely started (key fob included).

In terms of its run time capability, the GM15000ET, furnished with a 10.5 gallons fuel tank, can maintain operations for around 11 hours at 50% load on a full tank of gasoline (with fuel consumption averaging 0.95 gallons per hour). It also provides around 3.7 hours (on a 20 lbs tank - propane consumption around 1.27 GPH) of operation with propane.

The quite high THD (<23%) of the GM15000ET makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel features 8 AC outlets as follows:

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

It also sports 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle offering a convenient battery charging option.

Due to the featured twist-lock L14-30R receptacle, the GM15000ET is transfer switch ready: you may connect it to a breaker box to power your household during a power outage. The unit also features an ATS plug, which makes it compatible with automatic transfer switches.

Portability

At L28 x W31.6 x H28.7 in, the Genmax GM15000ET boasts a traditional open frame structure, ensuring stability and allowing for convenient maintenance access to components, promoting air circulation. The device has been designed for tough environments and demanding outdoor use.

As the generator's weight is 242 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, the constrained maneuverability is addressed with the assistance of its wheel kit and its folding handle, allowing for easy shifting once the generator is placed on the ground.

Features

Panel of the Genmax GM15000ET

The GM15000ET's control panel

Included in the control panel of the GM15000ET, a digital data center assists in tracking its status and activity by providing details on the voltage, power output, frequency and lifetime run hours. To offer you even more control and easy operation during nighttime, the panel is LED-lit.

In addition to this info, a light indicator on the device will signal if its oil levels are insufficient.

Benefiting from its built-in fuel gauge, the generator allows for easy and immediate gas level inspections.

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.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Genmax GM15000ET also comes with several accessories, including: battery charger, cover, key fob, natural gas hose with NPT adapter, neutral bonding plug, funnel, tool kit, propane hose and oil.

Product Video

The Genmax GM15000ET versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Genmax GM15000ET compare to multi-fuel generators of similar power (between 10000 and 14000 W).

  • Weight-wise, the Genmax GM15000ET has only 242 lbs, which renders it one of the lighter multi-fuel generators which produce 10000 to 14000 rated watts. If weight is an important consideration for you, the DuroStar DS13000MX stands out as one of the top contenders in this power category, with a dry weight of 209 pounds.
  • With noise emissions reaching as low as 76 dBA, this generator has a noise level typical for devices of its type and power category. If you wish to prioritize minimal noise, the Genmax GM17000iETC stands out as one of the quietest options among generators of similar power, with a rating of 63 dBA.
  • Thanks to an impressive running time of around 11 hours at 50% load, the GM15000ET benefits from a higher run time than many multi-fuel generators of a similar output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the WEN TF1450X, boasting with around 12 hours.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. At a 50% load, the generator consumes an estimated 0.95 gallons of gasoline per hour, falling within the average consumption range of units with similar output. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.68 GPH, the WEN TF1450X is a device you could look out for.
