Description
Zoom on the Generac GP15000E
In a nutshell, the Generac GP15000E is a powerful portable generator mostly geared towards:
- Professionals who want to ensure that a power failure will not prevent them from working
- Small homeowners in search of a full power backup solution
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.
Power & Run Time
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.
Its starting mechanism is based on a convenient and easy-to-use 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:
Furthermore, it has 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, due to the featured twist-lock L14-30R receptacle, the GP15000E is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.
Portability
With its dimensions of L48.5 x W31 x H39.5 in, the conventional, open frame design of the Generac GP15000E offers stability and allows the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.
Since the generator weighs 363 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). However, this lack of maneuverability is compensated by its wheel kit (⌀12.3") and its handle, with which you can conveniently shift it, once it's on the ground.
A lift hook located on the top of the frame offers an additional safety feature while facilitating the transport, loading and unloading of the generator.
Features
To help you monitor the GP15000E's status and activity, its control panel is equipped with a digital data center, giving you information on the lifetime run hours.
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 standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Generac GP15000E's package also includes these accessories: 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, so it is adequate for use 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).
- In terms of its dry weight, the Generac GP15000E stands at only 363 lbs, meaning that is one of the lighter devices of the 14000-20000 rated wattage category In terms of weight, one of the champions in their power range is the Lifan LF15000-EPL, standing at just 358 lbs.
- Given that the GP15000E reaches an autonomy of around 10 hours with a full tank and at 50% load, it is placed within the average autonomy range of similarly powerful generators. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Lifan LF15000-EPL, 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. As this generator uses an estimated 1.6 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you wish to further improve in the area of fuel efficiency, the Lifan LF15000-EPL, which boasts with a gas consumption of only 1.17 GPH, may be the right generator for you.
Price comparison
As you can see from this interactive chart, when compared to other 14000-20000W generators, the Generac GP15000E 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
- Several accessories included
- GFCI Outlets
- Electric start
- Lightweight for its kind (363 lbs)
- Decent run time
- Decent fuel efficiency
- No recoil back-up
- No remote start
- Not CARB-compliant

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).
