Description

This compact yet durable generator offers premium quality power, ideal for emergency backup power and jobsites. (source: Generac (opens in a new tab))

Zoom on the Generac XT8000EFI

In a nutshell, the Generac XT8000EFI is a portable generator mostly geared towards:

  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Professionals who want to ensure that a power failure will not prevent them from working

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's engine, 459 cc Generac 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 8000W and reaches a peak wattage of 10000W.

This generator features a simple traditional pull-start mechanism and also 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.

The fuel capacity of 8 gallons allows the XT8000EFI to operate for around 9.5 hours at 50% load with a full tank (fuel consumption around 0.84 GPH).

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

Outlets

The control panel includes the following 5 AC outlets:

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

As it features a twist-lock L14-30R receptacle, the XT8000EFI is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

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. The generator is designed for ideal use outdoors and in rough environments.

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). However, this lack of maneuverability is compensated by its wheel kit (⌀10") and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the Generac XT8000EFI

The XT8000EFI's control panel

The control panel of the XT8000EFI includes a digital data center, which assists you in monitoring its status and activity, as it provides information on the lifetime run hours.

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Generac XT8000EFI, the following accessories are also included: battery charger, oil, tool kit and funnel.

Emissions

The Generac XT8000EFI is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used 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).

  • With a dry weight of 216.1 pounds, the Generac XT8000EFI finds itself in the expected weight range for generators able to produce between 7500 and 8500 rated watts. If weight is your top priority, one of the champions in this power category is the Dewalt DXGNR8000, weighing just 183 pounds.
  • 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. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Firman H08053, reaching around 12 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 you wish to further improve in the area of fuel efficiency, the Pulsar PG10000B16, which boasts with a gas consumption of only 0.55 GPH, may be the right generator for you.

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.
