Description

Zoom on the Generac GP8000E

In a nutshell, the Generac GP8000E is a portable generator mostly geared towards:

  • Food truck owners and people participating in outdoor fairs, festivals or events
  • 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 parameters.

Power & Run Time

The Generac GP8000E in use

The Generac GP8000E

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 8000W as well as a peak wattage of 10000W.

This generator features a simple traditional pull-start mechanism and also a simple and elegant electric starter (battery included).

The GP8000E can operate for around 9.5 hours at 50% load with a full tank (fuel consumption around 0.79 GPH), due to its fuel capacity of 7.5 gallons.

The powering of sensitive electronic devices with the GP8000E is not recommended due to its relatively high THD (<20%).

The following are examples of possible devices which the generator will allow you to power simultaneously:Note: The examples above are based on a maximum load of 75% and estimated wattages. The devices also may not be able to start at the same time. For a more accurate estimation, use our wattage calculator.

Outlets

The control panel features the upcoming 5 AC outlets:

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

Since the GP8000E 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 Generac GP8000E has the following dimensions: L28.8 x W27.25 x H25.75 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 197 pounds. However, this lack of maneuverability is compensated by a wheel kit (⌀9.5") and a folding handle, with which you can conveniently displace it, once it's on the ground.

Features

The GP8000E's control panel

To help you monitor the GP8000E's status and activity, its control panel is equipped with an illuminated data center, giving you information on the lifetime run hours.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.

Besides the usual set of documentation and user manual to get you promptly started, Generac also included some oil in the GP8000E's packaging.

Emissions

The Generac GP8000E is neither EPA approved nor CARB-compliant..

However, it features a spark arrestor and therefore, can 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 197 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 Lifan LF8750iEPL, standing at just 185 lbs.
  • As the GP8000E offers 9.5 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the generators of a similar power. 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 Firman H08053, with 12 hours .
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. Standing at an estimated 0.79 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse WPro8500. With a fuel consumption of as little as 0.55 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this dynamic chart, when compared to other 7500-8500W generators, the Generac GP8000E is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.

The bottom line
