Description

Zoom on the Genmax GM12000XiT

In a few words, the Genmax GM12000XiT is a powerful portable inverter generator perfectly suited for:

  • Professionals who want to ensure that a power failure will not prevent them from working
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • RV travellers who wish to upgrade their experience to another level

Over the following sections, you'll uncover its power characteristics, the selection of outlets it offers, its overall portability, and the supplementary features it includes.

Power & Run Time

The Genmax GM12000XiT delivers 120/240V and features a tri-fuel technology, granting it the capability to utilize gasoline, propane, or natural gas. When utilizing gasoline, it achieves a running wattage of 10,000W and a peak wattage of 12,000W. Upon switching to propane, it benefits from 9,000 rated watts and 10,800 peak watts. Transitioning to natural gas operation provides 8,000W of rated wattage and 9,600W of starting wattage.

Enjoying a noise rating of 73 dBA (just slightly more noisy than a dishwasher), this inverter generator offers the versatility of starting with either a conventional pull-start mechanism or a convenient and efficient electric starter (battery included). Moreover, to offer you even more convenience, the GM12000XiT can also be remotely started (key fob included).

The generator also supports 2-wire start, enabling integration with compatible automatic transfer switches (ATS), solar battery systems, or hybrid inverter setups via a low-voltage contact-closure control circuit.

As for its running time, the GM12000XiT, along with its 10.5 gallons fuel capacity, can run for up to 16 hours with a full tank filled with gasoline (fuel consumption around 0.66 GPH). If propane is used, it can operate for up to 5 hours (estimation based on a 20 lbs tank - propane consumption around 0.94 GPH).

The GM12000XiT 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 3 DC outlets: there's a 12V 8A (cigarette lighter style) receptacle offering a convenient battery charging option and two 5V USB ports (USB-A) designed for hassle-free charging of various electronic devices such as smartphones and tablets, ensuring uninterrupted usage.

For RV owners with a 50-amp service, this Genmax unit is RV-ready, boasting a 14-50R outlet. In addition, with its twist-lock L14-30R receptacle, the GM12000XiT is designed to be transfer switch ready, allowing easy connection to your breaker box for powering your home during a blackout.

Portability

With dimensions of L30 x W27.4 x H27.7 in, the standard open frame design of the Genmax GM12000XiT provides stability and easy maintenance access to components, as well as good air circulation. This type of design is ideal for tough environments and heavy outdoor use.

Despite its 194 lbs, the generator falls under the category of 'portable,' signifying its movability, although its weight may hinder easy portability. However, the constrained maneuverability is addressed with the assistance of its set of wheels and its folding handle, allowing for easy shifting once the generator is placed on the ground.

The GM12000XiT's control panel

The GM12000XiT's status and activity may be monitored conveniently via the control panel, as it features a convenient meter, providing voltage, frequency, and lifetime hours data.

In addition to this info, the generator's light indicators provide visual feedback when the generator is ready, the oil level is too low and the generator is overloaded.

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

In terms of security, the generator features an overload protection (circuit breaker) and an automatic low oil shut-off, ensuring peace of mind during its use.

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 GM12000XiT also comes with several accessories, including: tool kit, battery charging cables, propane hose, funnel, key fob, natural gas hose with NPT adapter and oil.

The Genmax GM12000XiT versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Genmax GM12000XiT compare to multi-fuel generators of similar power (between 9500 and 10500 W).

  • In terms of its dry weight, the Genmax GM12000XiT stands at only 194 lbs, meaning that is one of the lightest multi-fuel devices of the 9500-10500 rated wattage category
  • With noise emissions rated as low as 73 dBA, this inverter generator falls within the typical noise range expected for devices of similar type and power. If noise emissions are important to you, one of the least noisy generators of this power range is the Genmax GM12500iET with only 62 dBA.
  • At a 25% load, the GM12000XiT's up to 16 hours of runtime on a full tank fall within the average autonomy range for similarly powerful multi-fuel generators. 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 Westinghouse WGen10500TFc, with up to 19 hours.
  • While run time is vital, it hinges on the fuel capacity. To grasp the full picture, we must also factor in fuel efficiency. When it comes to fuel efficiency among generators with similar wattage, this inverter generator lags behind, with a consumption rate of 0.66 GPH at a 25% load. If you wish to further improve in the area of fuel efficiency, the DuroMax XP12000EH, which boasts with a gas consumption of only 0.44 GPH, may be the right generator for you.

Price comparison

As you can see from these interactive charts, when compared to other 9500-10500W multi-fuel generators, the Genmax GM12000XiT is on the average side of the price range.

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