Zoom on the Generac GP8000E
In a nutshell, the Generac GP8000E is a portable generator mostly geared towards:
- 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 in need of safely powering high-intensity work or lighting equipment
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
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 via a conventional pull-start mechanism, or a simple and elegant electric starter (battery included).
Thanks to a fuel capacity of 7.9 gallons, the GP8000E can 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%).
The control panel provides 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.
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 device has been designed for tough 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 198 pounds. However, this lack of maneuverability is compensated by its wheel kit (⌀9.5") and its folding handle, with which you can conveniently shift it, once it's 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 far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).
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).
- 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:
As you can see from this interactive 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
- GFCI Outlets
- Electric start
- Lightweight for its kind (198 lbs)
- High run time
- Decent fuel efficiency
- No 50-amp output
- No remote start
- Not CARB-compliant
