Description
Zoom on the Generac GP15000E
In summary, the Generac GP15000E is a powerful portable generator especially useful for:
- Professionals who want to be able to deliver results, even during a power failure
- 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 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 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.
This Generac generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through 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. This type of design is ideal for tough environments and heavy outdoor use.
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.
The generator comes with an additional safety feature, a lift hook on the top of its frame, which is helpful during its transport, loading and unloading.
Features
One of the many GP15000E's features is the data center, included in its control panel, which conveniently provides information on the lifetime run hours and thus, helps you monitor its activity and status.
Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.
From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.
With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Generac GP15000E also comes with several accessories, including: funnel and tool kit.
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).
- As far as its dry weight is concerned, the Generac GP15000E weighs just 363 pounds and thus, it is one of the lightest 14000 to 20000 rated wattage generators.
- 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. 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.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator reaches an estimated fuel consumption of 1.6 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If you wish to further improve in the area of fuel efficiency, the Generac GP15500EFI, which boasts with a gas consumption of only 1.29 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 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

- 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
