Description
Zoom on the Generac GP15000E
In summary, the Generac GP15000E is a powerful portable generator especially useful for:
- Professionals in need of safely powering high-intensity work or lighting equipment
- Small homeowners in search of a full power backup solution
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Generac GP15000E
The Generac GP15000E's core is the 992 cc Generac OHVI 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 15000W and a peak wattage of 22500W.
This generator features a simple and elegant electric starter (battery included).
The GP15000E can operate for around 10 hours at 50% load with a full tank (fuel consumption around 1.6 GPH), due to its fuel capacity of 16 gallons.
The GP15000E is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<20%).
Outlets
The control panel provides the upcoming 8 AC outlets:
Additionally, it features 1 DC outlet: there's a 12V 10A receptacle with which charging your batteries is made easy.
While this Generac generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor. Besides, because the GP15000E is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.
Portability
The design of the Generac GP15000E is a typical, open frame, with the dimensions of L48.5 x W31 x H39.5 in, offering support and stability and enabling the possibility of raising it above ground level. The design is ideal for rough environments and demanding outdoor use.
As the generator's weight is 363 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 (⌀12.3") and its handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.
Further safety during transport, loading and unloading of the device is provided by a lift hook, which is placed on the top of the generator's frame.
Features
The GP15000E's control panel
Monitoring of the GP15000E'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.
From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.
While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Generac GP15000E, the following accessories are also included: tool kit and funnel.
Emissions
The Generac GP15000E 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.
Product Video
The Generac GP15000E versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Generac GP15000E compare to generators of similar power (between 14000 and 20000 W).
- Regarding its weight, the Generac GP15000E only weighs in at 363 pounds, which means it's one of the lightest generators in the 14000-20000 rated wattage range.
- As the GP15000E offers around 10 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. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Westinghouse WGen20000, which is able to run for around 11 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. With an estimated gasoline consumption of 1.6 GPH (gallon per hour) at 50% load, this generator is among the more fuel efficient of the products in the above-mentioned wattage range. If fuel consumption is your top priority, we suggest to check out the Westinghouse WGen20000, which has a fuel consumption of only 1.56 GPH and thus, is one of the most efficient devices in our database.
Price comparison
As you can see from this interactive chart, when compared to other 14000-20000W generators, the Generac GP15000E 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.

- Several accessories included
- GFCI Outlets
- Electric start
- Lightweight for its kind (363 lbs)

What is the noise rating of the GP15000E?
Due to the lack of standardization in noise emission measurement, Generac does not provide their units' noise levels.
Oil capacity? (Asked February 15, 2020)
With filter change, 54.4 fl. oz. Without filter change 44.8 fl. oz.
I read something about it not being good for electonic devices like computer maybe i read something wrong? (Asked February 08, 2022)
The unit is not suitable for powering equipment that contains sensitive electronic components. You may want to consider an inverter generator or a generator with a low THD. You may also want to read more about Total Harmonic Distortion (THD).
