Description
Zoom on the Genmax GM13500iETC
In a nutshell, the Genmax GM13500iETC is a powerful portable inverter generator mostly geared towards:
- 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 forthcoming sections, you'll delve into its power characteristics, the various outlets it offers, its overall portability, and the additional features it boasts.
Power & Run Time
The Genmax GM13500iETC 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 11,500W and a peak wattage of 13,500W. Upon switching to propane, it benefits from 10,500 rated watts and 12,500 peak watts. Transitioning to natural gas operation provides 9,500W of rated wattage and 10,500W of starting wattage. The impressive running wattage makes this unit one of the biggest inverter generators currently on the market.
Operating with a noise rating of 62 dBA (just slightly more noisy than a normal conversation), this inverter generator offers two starting options: a classic hand-operated recoil starting mechanism and an intuitive and practical electric starter (battery included). For additional convenience, the GM13500iETC may also be remotely started (key fob included).
Regarding its running time, the GM13500iETC, with a 6.9 gallons fuel capacity, can operate for up to 11.2 hours with a full tank of gasoline (fuel consumption around 0.62 GPH). When using propane, it can run for up to 5.5 hours (estimation based on a 20 lbs tank - propane consumption around 0.85 GPH).
Delicate electronics can be plugged in the AC outlets safely, as the GM13500iETC generates a clean sine wave, reaching a <3% Total Harmonic Distortion (THD).
Outlets
The control panel provides the upcoming 6 AC outlets:
In addition, it provides 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle with which you may charge your batteries with ease.
While this Genmax generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor. Besides, the unit features an ATS plug, which makes it compatible with automatic transfer switches.
Portability
With its enclosed inverter generator design (L30.7 x W24 x H29.5 in), the Genmax GM13500iETC offers superior aesthetics and operates with minimized noise levels, distinguishing itself from standard, open frame generators. The featured design follows the latest trends and is ideal for easy and recreational use.
Though weighing 276 lbs, the generator remains classified as 'portable,' indicating its capability to be moved, though its weight could pose transport challenges. Nevertheless, the restricted maneuverability is counteracted by its set of 4 wheels and its folding handle, enabling easy shifting once the generator is set in place.
Features
The GM13500iETC's control panel
With a digital data center integrated into its control panel, the GM13500iETC provides real-time insights into the lifetime run hours, power output, voltage and frequency, enabling easy monitoring of its status and activity. To offer you even more control and easy operation during nighttime, the panel is LED-lit.
In addition to this info, the device’s light indicators will display if its oil levels are insufficient, the generator is on overload and the generator is ready.
Benefiting from its built-in fuel gauge, the inverter 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 GM13500iETC also comes with several accessories, including: battery charger, funnel, tool kit, key fob, natural gas hose with NPT adapter and propane hose.
Genmax App
The app allows remote monitoring
Genmax’s app lets you pair your smartphone with your GM13500iETC inverter generator. It allows you to always know exactly what is going on.
Using Bluetooth technology, the generator communicates with the app (available on iOS (opens in a new tab) and Android (opens in a new tab) devices) to conveniently monitor power consumption, fuel level, remaining runtime, and even remotely shut off your generator directly from your smartphone.
The information displayed within the app is identical to the information displayed on the LCD screen of the GM13500iETC.
Product Video
The Genmax GM13500iETC versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Genmax GM13500iETC compare to multi-fuel generators of similar power (between 10000 and 14000 W).
- With a dry weight of 276 lbs, the Genmax GM13500iETC sits comfortably within the expected weight range for multi-fuel devices generating 10000 to 14000 rated watts. If weight is a key factor for your needs, the DuroStar DS13000MX is noteworthy for being one of the top contenders in this power range, with a dry weight of 209 pounds.
- Rated at a lowest possible noise level of 62 dBA, this inverter generator positions itself amongst the most quiet of the products of similar type and power.
- In terms of autonomy, the GM13500iETC offers up to 11.2 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 Westinghouse WGen11500TFc, which offers one of the highest autonomy among devices with similar power output, lasting up to 19 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This inverter generator is somewhat less fuel-efficient than devices of comparable output: its estimated fuel consumption reaches 0.62 GPH at a 25% load. If you wish to acquire one of the most gasoline efficient products of this power range, the DuroMax XP15000HXT+, with a fuel consumption of 0.46 GPH could be in your good books.
