Zoom on the Generac GP8000E
In summary, the Generac GP8000E is a portable generator especially useful for:
- Food van owners who know that just a short power outage could lose them hundreds of dollars
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Professionals who want to be able to deliver results, even during a power failure
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Generac GP8000E is powered by a 420 cc Generac OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 8,000W as well as a peak wattage of 10,000W.
This generator can be started thanks to a conventional pull-start mechanism, but also to a simple and elegant electric starter (battery included).
The fuel capacity of 7.9 gallons allows the GP8000E to operate for around 11 hours at 50% load with a full tank (fuel consumption around 0.72 GPH).
The GP8000E is unsuitable for the powering of sensitive electronic devices due to its high THD (<20%).
Outlets
The control panel features the upcoming 5 AC outlets:
As it features a twist-lock L14-30R receptacle, the GP8000E 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 design of the Generac GP8000E is a typical, open frame, with the dimensions of L27.2 x W27 x H26.5 in, offering support and stability and enabling the possibility of raising it above ground level. The design is ideal for rough environments and demanding outdoor use.
As the generator's weight is 198 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀9.5") and its folding handle, once it is placed on the ground.
Features
The GP8000E's control panel
A digital data center, one of the features of the GP8000E's control panel, gives you information on the lifetime run hours, and thus, is helpful for the monitoring of its activity and status.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.
Besides the usual set of documentation and owner's manual (opens in a new tab) to get you promptly started, Generac also included some oil in the GP8000E's packaging.
Emissions
The Generac GP8000E is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
However, it features a spark arrestor and thus, may be used in forested areas.
The Generac GP8000E versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Generac GP8000E compare to generators of similar power (between 7500 and 8500 W).
- Weight-wise, the Generac GP8000E has only 198 lbs, which renders it one of the lighter generators which produce 7500 to 8500 rated watts. In terms of weight, one of the champions in their power range is the Dewalt DXGNR8000, standing at just 183 lbs.
- Thanks to an impressive running time of around 11 hours at 50% load, the GP8000E benefits from a higher run time than many generators of a similar output. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Champion 100416, with around 12.5 hours.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This generator has an average fuel consumption among comparably powerful devices, as it reaches 0.72 GPH (gallon per hour) at a 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.55 GPH, the Pulsar PG10000B16 is a device you could look out for.
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 GP8000E is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.

User Reviews
I’ve had this generator a little over 5 years. Have ran it 115 hours without a single issue. even the original battery is still holding up. Iget about 12 hours per tank while it’s connected to my house. Idle control and a 50 amp outlet would be nice added features. Overall very happy with this purchase and will buy Generac again in the future.
I could not disagree more with the review below. My GP8000e has run without any problems for several years. The electric start is great. I added a solar recharge for my battery and a over temperature kill switch in case the system overheats.
I just purchased a GP8000e 49 state version. It is made in Vietnam and nit the USA. very cheaply made and it shows. If Generac cut cost on the things that are visible, what did they do with the critical components? Very disappointed in this unit.
