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.
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's engine, 992 cc Generac OHVI 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 15000W and reaches a peak wattage of 22500W.
The generator features a simple and elegant electric starter (battery included).
The fuel capacity of 16 gallons allows the GP15000E to operate for around 10 hours at 50% load with a full tank (fuel consumption around 1.6 GPH).
The powering of sensitive electronic devices with the GP15000E is not recommended due to its relatively high THD (<20%).
The control panel includes the following 8 AC outlets:
Furthermore, it has 1 DC outlet: there's a 12V 10A receptacle allowing you to easily charge your batteries.
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, 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.
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 featured design is ideal for the outdoors and all tough environments.
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.
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.
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.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.
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
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. 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.
