Features & Benefits of Generac XT8000EFI

The Generac XT8000EFI is a high-end generator. Its performance is suitable for job sites or use as a backup generator.

Power Output, Run Time

The Generac XT8000EFI uses a 459cc engine that produces 8,000W of power. A built-in digital feature called TruePower regulates the power output to prevent surges and protect electronics and other sensitive tools or appliances.

You can get up to 10,000W in short bursts to power an appliance or tool while it starts and draws more power.

The run time of the generator is 9.5 hours on a 50% load. There is an eight-gallon tank that will keep the generator running for hours.

You can get a better idea of the kind of performance to expect in this test performed on a similar model.

Outlets, Hook Up Provisions, and Possibilities

The Generac XT8000EFI has a total of three outlets to hook up to your house: two 120V GFCI and a 120/240V. The generator uses covered outlets for safety as well as built-in circuit breakers.

As the XT8000EFI model isn’t an inverter generator, you won’t be able to wire it in parallel with other generators.

This generator uses gasoline, but a YouTube user was able to convert it to use other fuel sources. You can find out more in the video he created.

Starting, Remote Start

While the Generac XT8000EFI doesn’t come with a remote start option, you will find a convenient push-button start on the control panel. There is no need to pull on a cable or rope to get the generator to start.

The downside of the push-button start is that you won’t get a choke mode that helps the generator start in cold weather.

Portability, Dimensions, Weight

This Generac generator is a large appliance. It might not be your best choice if you’re shopping for a portable generator, but keep in mind that you won’t get the same performance if you opt for a smaller and lighter unit.

The Generac XT8000EFI weighs around 216lb and measures 31.8×27.4×27.1. It’s a heavy generator, but there are two sturdy 10” wheels with deep lugs so you can transport the generator on any surface. You’ll also find some sturdy handles attached to the frame to make the generator more portable.

Other Features

There are other noteworthy features to discuss for the Generac XT8000EFI.

Paralleling With Other Generators

The XT8000EFI is a standard portable generator. It doesn’t have a built-in power inverter, which means you won’t be able to connect it to other generators to increase the power output.

Control Panel Features

This generator comes with a user-friendly control panel. You’ll find three outlets, an electric start push-button, and an idle control switch to save fuel when you don’t need to use the generator.

The control panel has different LED indicators that show you the current power usage, the outlets powered, and the fuse status. A small display also tells you when the generator will need maintenance again.

Security, Alarms, Accessories

There are a few features that improve security, such as the auto-shutdown that will kick in when oil gets low. In addition, the generator uses TruePower technology to deliver constant voltage and prevent surges.

The PowerBar displayed on the control panel can help you keep an eye on the current load. What’s more, the GFCI covered outlets are another of the generator’s safety measures. The GFCI outlets are a must-have feature if you need an OSHA-compliant portable generator.

There are no alarms or accessories.


The Generac XT8000EFI is EPA and CARB-compliant when it comes to emissions. However, you’ll need to perform maintenance regularly to keep emissions below these standards.


Generac offers a two-year limited warranty for residential use. You’ll get a one-year limited warranty for commercial use.

There are a few additional things you should know about the Generac XT8000EFI.

What is the fuel injection feature on the Generac XT8000EFI?

This generator comes with a built-in fuel injection feature. Besides reducing fuel usage, this helps you start the generator easily. It’s ideal for long-term storage and reduces the risk of fuel going bad during storage.

The electronic fuel-injected engine also delivers a more reliable power output with fewer surges. You can learn more about the EFI feature in this video.

Is there a recall on the Generac XT8000EFI?

Generac announced a recall for some XT8000EFI models in July 2021. There are no issues with the generator itself, but there is a risk of having the handle snap shut when moving the generator, which can cause injuries.

It’s not a problem if you’re shopping for a brand new generator, but you need to be aware of this problem if you’re looking at used generators.

Things to Consider Before Buying the Generac XT8000EFI

This generator is best suited for contractors and businesses. Still, it’s a good option for homeowners who need a reliable source of power. However, most homeowners can settle for a more affordable generator with a lower running watt rating since 8,000W is probably more than you’ll need.

We recommend the Generac XT8000EFI because of the performance of the fuel-injected engine, the built-in safety features, and the overall standard of the product. It costs more than most generators, but it’s a durable investment that delivers reliable performance.

While the Generac XT8000EFI is a great option for contractors and homeowners in need of a powerful generator, few alternatives are to consider.

Generac GP8000E

The Generac GP8000E is an alternative worth considering in a similar price range. It also delivers 8,000W as standard and up to 10,000W in short bursts. The noise level is also similar.

It lacks the EFI and idle feature you’ll find on the XT8000EFI model. However, it’s lighter by around 20lbs. and has a better run time since you get up to 11 hours of use on a 50% load.

Another reason to consider the GP8000E model is the PowerRush feature that makes the motor easier to start. This feature could make the GP8000E model the better choice for those who live in cold climates.

It’s a tri-fuel generator, which means you can use gasoline, propane, or natural gas to power it. You can typically save money and reduce emissions by using propane or natural gas instead of gasoline.

The noise level of 72dBA is similar to the XT8000EFI, and so is the weight. There is also a CO shield feature that monitors carbon monoxide levels and shuts down the generator if these levels get too high.

Predator 8,750W Inverter Generator

This 8,750W Predator generator is another alternative to consider if you need an inverter generator. It costs more than the Generac XT8000EFI, but you can get two units and wire them in parallel to double the power output.

You’ll get more outlets compared to the XT8000EFI as well as two USB plugs. It’s slightly louder than the XT8000EFI at 75dBA but is much lighter at around 150lbs.

There is a built-in feature that monitors CO levels and automatically shuts down the generator.


The Generac XT8000EFI represents a significant investment, but it’s a durable and reliable option if you need a portable power system for job sites or a performing backup generator.
