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
- Homeowners who wish to power almost all appliances in their house under any circumstances
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 GP15000E houses a 992 cc Generac OHVI 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 15,000W along with a peak wattage of 22,500W.
The generator features a simple and elegant electric starter (battery included).
Thanks to a fuel capacity of 16 gallons, the GP15000E can operate for around 10 hours at 50% load with a full tank (fuel consumption around 1.6 GPH).
As the GP15000E has a high THD (<20%), it is not recommended to use it to power sensitive electronic devices.
Outlets
The control panel provides the upcoming 8 AC outlets:
It also sports 1 DC outlet: there's a 12V 10A receptacle with which charging your batteries is made easy.
Even if this Generac generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle. Besides, as it features a twist-lock L14-30R receptacle, the GP15000E is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.
Portability
The Generac GP15000E has a conventional, open frame design, of the following dimensions: L48.5 x W31 x H39.5 in, which offers support and allows it to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 363 lbs make it incredibly difficult to manually lift and transport. 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
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.
Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.
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, making it usable 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).
- Weight-wise, the Generac GP15000E has only 363 lbs, which renders it one of the lightest generators which produce 14000 to 20000 rated watts.
- 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. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Westinghouse WGen20000, as it provides around 11 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This generator has an estimated fuel consumption of roughly 1.6 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If fuel consumption is your top priority, we suggest to check out the Generac GP15500EFI, which has a fuel consumption of only 1.29 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 average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.

- GFCI Outlets
- 5 different AC outlet types
- Electric start
- Lightweight for its kind (363 lbs)
- Made in USA
- Decent run time
- Decent fuel efficiency
- No recoil back-up
- No remote start
- Not CARB-compliant
