Description
Zoom on the Genmax GM8000iETC
In a nutshell, the Genmax GM8000iETC is a compact portable inverter generator mostly geared towards:
- RV travellers looking for even more independence
- Occasional participants of outdoor events, competitions, concerts and festivals
- 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
- Professionals who want to ensure that a power failure will not prevent them from working
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 GM8000iETC 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 6,000W and a peak wattage of 8,000W. Switching to propane provides 5,500 rated watts and 7,200 peak watts, while natural gas operation delivers 4,800W of rated wattage and 6,500W of starting wattage. Furthermore, its parallel capability (parallel kit not included) allows for increasing of power output when connected to another similar or compatible unit, ensuring expanded energy capacity and reliability for various applications.
Enjoying a noise rating of 62 dBA (just slightly more noisy than background music), this inverter generator can be started thanks to a classic hand-operated recoil starting mechanism, but also to a hassle-free and practical electric starter (battery included). To increase convenience, the GM8000iETC offers remote starting functionality, allowing for easy operation from a distance (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.
The running time of the GM8000iETC, with its 3.6 gallons fuel capacity, can reach up to 10 hours on a full tank of gasoline (fuel consumption around 0.36 GPH). With propane, it can reach up to 9.5 hours (estimation based on a 20 lbs tank - propane consumption around 0.49 GPH).
Sensitive electronics can be safely plugged in the AC outlets, as the GM8000iETC produces a clean sine wave, with a <3% Total Harmonic Distortion (THD).
Outlets
The control panel features 4 AC outlets as follows:
Moreover, it boasts 2 DC outlets: there's two 5V USB ports (1 x USB-A and 1 x USB-C) designed for hassle-free charging of various electronic devices such as smartphones and tablets, ensuring uninterrupted usage.
With its 14-50R outlet, this Genmax unit is RV-ready for owners with a 50-amp service in their RVs.
Portability
Since the Genmax GM8000iETC is an inverter generator, its closed design (L24 x W18.5 x H21.1 in) not only provides an aesthetic advantage but also contributes to reduced noise levels compared to conventional, open frame devices. This modern design aims to provide an ideal power solution to recreational users.
Despite its 144.6 lbs, the generator falls under the category of 'portable,' signifying its movability, although its weight may hinder easy portability. Nonetheless, the limited maneuverability is compensated for by utilizing its set of 2 wheels and its telescopic handle, which facilitates shifting once the generator is set on the ground.
Features
For easy status and activity monitoring of the GM8000iETC, its control panel integrates a digital data center, offering insights into the fuel level, power output, frequency, voltage and lifetime run hours.
In addition to this info, the device's light indicators will illuminate to indicate if the oil level is too low, the generator is ready and the generator is on overload.
Regarding security, the generator comes with an automatic low oil shut-off and an overload protection (circuit breaker), providing 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.
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Genmax GM8000iETC also comes with some accessories: funnel, key fob and tool kit are included.
Genmax App
Genmax’s app lets you pair your smartphone with your GM8000iETC 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 GM8000iETC.
The Genmax GM8000iETC versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Genmax GM8000iETC compare to inverter generators of similar power (between 5500 and 6500 W).
- At 144.6 lbs dry, the Genmax GM8000iETC is consistent with the standard weight profile for inverters ranging from 5500 to 6500 rated watts. If weight is a key factor for your needs, the Genmax GM6250iET is noteworthy for being one of the top contenders in this power range, with a dry weight of 102.6 pounds.
- This inverter generator has a somewhat average expected noise for its type and power range, rated at 62 dBA. For those who are looking for a less noisy device, we suggest the Honda EU7000iS. With just 52 dBA, it is one of the most quiet devices in this power range.
- The GM8000iETC's autonomy is somewhat low end compared to devices of its type and power range, as it reaches only up to 10 hours at 25% load on a full tank. If run time is one of your main concerns, the DuroMax XP7000iHT could be worth looking at. It boasts one of the highest run times among units of comparable power, lasting up to 16 hours.
- Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. This inverter generator doesn't excel in fuel efficiency when compared to others of its kind: it consumes approximately 0.36 GPH at a 25% load. If gasoline efficiency is at the top of your list, you may want to have a look at the DuroMax XP7000iHT, which has great fuel efficiency, with a gas consumption of only 0.19 gallons per hour.
