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
- 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.
This generator can be started thanks to a conventional pull-start mechanism, but also to a convenient and easy-to-use 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).
Since the GP8000E has a somewhat high THD (<20%), it is advisable to not use it for the powering of sensitive electronic devices.
The control panel features the following 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.
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 generator is designed for ideal use outdoors and in rough environments.
Since the generator weighs 198 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is 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.
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.
Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.
As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), 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).
- Regarding its weight, the Generac GP8000E only weighs in at 198 pounds, which means it's one of the lighter generators in the 7500-8500 rated wattage range. If weight matters to you, one of the champions in this power range is the Dewalt DXGNR8000 with only 183 pounds.
- With a run time of around 11 hours at 50% load, the GP8000E has one of the higher run times, compared to its similarly powerful peers. 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.
- While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. Standing at an estimated 0.72 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 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 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
