Zoom on the Generac GP8000E
In a nutshell, the Generac GP8000E is a portable generator mostly geared towards:
- Food truck owners who do not wish to see their business interrupted under any circumstances
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Professionals who want to ensure that a power failure will not prevent them from working
Power & Run Time
The Generac GP8000E's engine, 420 cc Generac OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 8,000W and reaches a peak wattage of 10,000W.
Its starting mechanisms include a simple traditional pull-start mechanism and a convenient and easy-to-use electric starter (battery included).
With a full tank, the GP8000E can operate for around 11 hours at 50% load (fuel consumption around 0.72 GPH), thanks to its fuel capacity of 7.9 gallons.
The quite high THD (<20%) of the GP8000E makes it unsuitable for powering sensitive electronic devices.
The control panel includes the following 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.
The Generac GP8000E has the following dimensions: L27.2 x W27 x H26.5 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.
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, thanks to its wheel kit (⌀9.5") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.
Monitoring of the GP8000E'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.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.
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.
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, making it usable 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).
- As far as its dry weight is concerned, the Generac GP8000E weighs just 198 pounds and thus, it is one of the lighter 7500 to 8500 rated wattage generators. If weight matters to you, one of the champions in this power range is the Westinghouse ecoGen10000 with only 147.7 pounds.
- Since the GP8000E boasts with a run time of around 11 hours at 50% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 100416, reaching around 12.5 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. As this generator uses an estimated 0.72 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you wish to acquire one of the most gasoline efficient products of this power range, the Pulsar PG10000B16, with a fuel consumption of 0.55 GPH could be in your good books.
Here's a list of the most popular specific comparisons:
As you can see from these interactive charts, 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.
