Description

Zoom on the Genmax GM10500XiT

In summary, the Genmax GM10500XiT is a powerful portable inverter generator especially useful for:

  • Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • RV travellers wishing to enhance their freedom and nomad lifestyle

The subsequent sections will explore in detail its power characteristics, the diverse outlets it provides, its overall portability, and the supplementary features it offers.

Power & Run Time

The Genmax GM10500XiT in use

The Genmax GM10500XiT

The Genmax GM10500XiT 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 7,800W and a peak wattage of 10,500W. Switching to propane provides 7,000 rated watts and 9,500 peak watts, while natural gas operation delivers 6,250W of rated wattage and 8,500W of starting wattage. Furthermore, its parallel capability (parallel kit not included) allows power output to increase when connected to another similar or compatible unit, ensuring expanded energy capacity and reliability for various applications.

The inverter generator, rated for a noise of 74 dBA (just slightly more noisy than a shower), provides flexibility in starting, offering both a conventional pull-start mechanism and a user-friendly and efficient electric starter (battery included). For additional convenience, the GM10500XiT may also be remotely started (key fob included).

Regarding its running time, the GM10500XiT, with a 5.8 gallons fuel tank, can operate for up to 13.5 hours with a full gasoline tank (with fuel consumption estimated at around 0.43 gallons per hour). It also offers up to 8 hours (estimation based on a 20 lbs tank - propane consumption around 0.59 GPH) of operation when using propane.

As the GM10500XiT produces a clean sine wave, with a <3% Total Harmonic Distortion (THD), sensitive electronics may be plugged in the AC outlets safely.

Outlets

The control panel features the upcoming 4 AC outlets:

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

Furthermore, it has 3 DC outlets: there's a 12V 8A (cigarette lighter style) receptacle providing easy battery charging capabilities and two 5V USB ports (1 x USB-A and 1 x USB-C) ideal for charging various electronic devices such as smartphones and tablets.

With its 14-50R outlet, this Genmax unit is RV-ready for owners with a 50-amp service in their RVs. In addition, because the GM10500XiT is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household. The unit also features an ATS plug, which makes it compatible with automatic transfer switches.

Portability

With dimensions of L25.2 x W19.8 x H21.3 in, the traditional open frame design of the Genmax GM10500XiT ensures stability while allowing easy maintenance access to components and promoting effective air cooling. The device has been designed for tough environments and demanding outdoor use.

Since the generator weighs 123.5 lbs, it could be potentially be difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). 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.

Features

The GM10500XiT's control panel

A digital data center, one of the features of the GM10500XiT's control panel, gives you information on the power output, voltage, frequency and lifetime run hours, and thus, is helpful for the monitoring of its activity and status.

In addition to this info, light indicators on the device will notify you if the oil level is too low, the generator is on overload and the generator is ready.

Equipped with a built-in fuel gauge, the inverter generator facilitates swift gas level checks.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

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.

In addition to the traditional documentation and an owner's manual (opens in a new tab) to help you get started promptly, the Genmax GM10500XiT also includes several accessories: natural gas hose with NPT adapter, funnel, cover, tool kit, propane hose, key fob and neutral bonding plug.

The Genmax GM10500XiT versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Genmax GM10500XiT compare to multi-fuel generators of similar power (between 7500 and 8500 W).

  • Regarding its weight, the Genmax GM10500XiT only weighs in at 123.5 pounds, which means it's one of the lightest multi-fuel generators in the 7500-8500 rated wattage range.
  • Since the inverter generator's noise is rated at 74 dBA, it has the roughly average expected noise for a device of similar type and power. If noise emissions are important to you, one of the least noisy generators of this power range is the DuroMax XP9500iH with only 61 dBA.
  • As for its runtime, the GM10500XiT runs for up to 13.5 hours at a 25% load, placing it towards the low end among comparable multi-fuel products. If extended autonomy is what matters most to you, the DuroMax XP10000EH could be an excellent choice, offering one of the longest run times among units in its power category, reaching 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. Compared to similar devices, this inverter generator is less fuel-efficient than most: it burns around 0.43 gallons of gasoline per hour at a 25% load. If you're placing a high priority on fuel consumption, the DuroMax XP9500iH, with a low fuel consumption rate of 0.34 GPH, could be an option to consider.
