Zoom on the Generac XT8000EFI

In summary, the Generac XT8000EFI is a portable generator especially useful for:

  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals in need of safely powering high-intensity work or lighting equipment

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Generac XT8000EFI in use

The Generac XT8000EFI

The Generac XT8000EFI houses a 459 cc Generac 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 8000W along with a peak wattage of 10000W.

This generator can be started via a conventional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included).

The Electronic Fuel Injection (EFI) system enhances the engine's reliability, lowers fuel consumption, improves startup, reduces servicing, boosts stale fuel resistance, and offers better altitude adaptability.

With a full tank, the XT8000EFI can operate for around 9.5 hours at 50% load (fuel consumption around 0.84 GPH), thanks to its fuel capacity of 8 gallons.

Sensitive electronics can be safely plugged in the AC outlets, as the XT8000EFI produces a clean sine wave, with a <5% Total Harmonic Disruption (THD).

Outlets

The control panel includes the following 5 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle

Since the XT8000EFI bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

The dimensions of the Generac XT8000EFI, which are L31.8 x W24.7 x H27.1 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.

Since the generator weighs 216.1 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Still, once it is on the ground, its wheel kit (⌀10") and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

The XT8000EFI's control panel

Monitoring of the XT8000EFI's status and activity is made possible by a digital data center, which provides information on the lifetime run hours and is one of the features of its control panel.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Generac XT8000EFI also comes with several accessories, including: tool kit, battery charger, oil and funnel.

Emissions

The Generac XT8000EFI is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor, making it usable in forested areas.

The Generac XT8000EFI versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Generac XT8000EFI compare to generators of similar power (between 7500 and 8500 W).

  • Having a dry weight of 216.1 lbs, the Generac XT8000EFI belongs in the expected weight range for generators which produce 7500 to 8500 rated watts. Regarding dry weight, one of the champions in the same power range is the Dewalt DXGNR8000, with a dry weight of only 183 lbs.
  • The XT8000EFI, offering a run time of around 9.5 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its peers. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Champion 100416, as it provides around 12.5 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. This generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.84 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse WPro8500, which has a fuel consumption of only 0.55 GPH and thus, is one of the most efficient devices in our database.

Here's a list of the most popular specific comparisons:

Price comparison

As you can see from this interactive chart, when compared to other 7500-8500W generators, the Generac XT8000EFI is on the average side of the price range.

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

What is the noise rating of the XT8000EFI?

Due to the lack of standardization in noise emission measurement, Generac does not provide their units' noise levels.

My question involves connecting the XT8000EFI into a manual transfer switch. I have been told and have read that the generator is required to have a "floating neutral". If this is correct how do I convert this generator from a bonded neutral to a floating neutral? Your review says that it is transfer switch ready and that the neutral is bonded to the frame. As you can tell I lack the specific knowledge to do it myself, I'll be better off leaving it to a professional but I do want to know how and what to look for when the electrician gets here to safely set it . (Asked September 25, 2020)

We invite you to read our article on the differences between bonded and floating neutral, as well as the one on neutral conversion.
