Zoom on the Generac GP8000E
In a nutshell, the Generac GP8000E is a portable generator mostly geared towards:
- Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
- Professionals who want to be able to deliver results, even during a power failure
Power & Run Time
The Generac GP8000E houses a 420 cc Generac OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 8000W along with a peak wattage of 10000W.
Its starting mechanisms include a simple traditional pull-start mechanism and a convenient and easy-to-use electric starter (battery included).
With a fuel capacity of 7.9 gallons, the GP8000E may run for around 11 hours at 50% load with a full tank (fuel consumption around 0.72 GPH).
The powering of sensitive electronic devices with the GP8000E is not recommended due to its relatively high THD (<20%).
The control panel features the upcoming 5 AC outlets:
As the GP8000E holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.
With its dimensions of L27.2 x W27 x H26.5 in, the conventional, open frame design of the Generac GP8000E offers stability and allows the generator to be raised above ground level. This type of design is ideal for tough environments and heavy 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). However, its challenging mobility is solved by its wheel kit (⌀9.5") and its folding handle, which will ease its displacement, once it is on the floor.
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.
The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.
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 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).
- 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 you are concerned by weight, one of the champions in the above mentioned power range is the Lifan LF8750iEPL, with a dry weight of just 185 pounds.
- The GP8000E provides a higher run time than similarly powerful devices, reaching around 11 hours at 50% load. 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.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator reaches an estimated fuel consumption of 0.72 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.55 GPH, the Pulsar PG10000B16 is a device you should look out for.
Here's a list of the most popular specific comparisons:
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.
The bottom line
- In the expected price range
- GFCI Outlets
- Electric start
- Lightweight for its kind (198 lbs)
- High run time
- Decent fuel efficiency
- No remote start
- Not CARB-compliant
