Zoom on the Generac GP15000E
In a nutshell, the Generac GP15000E is a powerful portable generator mostly geared towards professionals who want to be able to deliver results, even during a power failure.
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's design includes a gasoline-fueled 992 cc Generac OHVI 4-stroke engine. With a 120/240V output, it gives a running wattage of 15000W and also a peak wattage of 22500W.
Its starting mechanism is based on a simple and elegant electric starter (battery included).
With a full tank, the GP15000E can operate for around 10 hours at 50% load (fuel consumption around 1.6 GPH), thanks to its fuel capacity of 16 gallons.
As the GP15000E has a relatively high THD (<20%), it is not recommended to use it to power sensitive electronic devices.
The control panel features the upcoming 8 AC outlets:
In addition, it provides 1 DC outlet: there's a 12V 10A receptacle with which you may charge your batteries with ease.
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, since the GP15000E bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.
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. The featured design is ideal for the outdoors and all tough environments.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 363 pounds. 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.
A lift hook, which is on the top of the frame, serves as an extra safety feature for the transport, unloading and loading of the device.
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 fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.
As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.
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: tool kit and funnel.
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.
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 18000 W).
- As for its weight, the Generac GP15000E weighs only 363 pounds, making it one of the lightest generators in the 14000-18000 rated wattage category.
- Thanks to an impressive running time of around 10 hours at 50% load, the GP15000E benefits from one of the highest run times among generators of a similar output
- 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 is one of the most fuel efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 1.6 GPH (gallon per hour) at 50% load.
As you can see from this interactive chart, when compared to other 14000-18000W 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.
