Description
A portable unit ideal for applications requiring a large amount of power without being permanent. Ideal for job sites and emergency applications.
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
- Homeowners who wish to power almost all appliances in their house under any circumstances
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.
Power & Run Time
The Generac GP15000E
The Generac GP15000E's engine, 992 cc Generac OHVI 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 15,000W and reaches a peak wattage of 22,500W.
This generator utilizes a user-friendly and efficient electric starter (battery included) for startup.
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 features the following 8 AC outlets:
Furthermore, it showcases 1 DC outlet: there's a 12V 10A receptacle allowing you to easily charge your batteries.
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, thanks to its twist-lock L14-30R receptacle, the GP15000E is transfer switch ready, facilitating easy hookup to your breaker box to provide backup power for your home during blackouts.
Portability
Measuring L48.5 x W31 x H39.5 in, the Generac GP15000E showcases a classic open frame layout, guaranteeing stability and simple maintenance access to components, while facilitating air circulation. The device has been designed for tough environments and demanding outdoor use.
While technically classified as 'portable' due to its ability to be moved, the 363 lbs of this generator make manual lifting and transportation incredibly difficult. However, the constrained maneuverability is addressed with the assistance of its wheel kit (⌀12.3") and its handle, allowing for easy shifting once the generator is placed 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
The GP15000E's control panel
Designed with a digital data center, the control panel of the GP15000E grants you access to crucial data on the lifetime run hours, ensuring practical monitoring of its status and activity.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
From a security standpoint, the generator is furnished with an automatic low oil shut-off and an overload protection (circuit breaker), ensuring peace of mind during operation.
Beyond the standard documentation and an owner's manual (opens in a new tab) to assist with setup, the Generac GP15000E ships with supplementary accessories: funnel and tool kit.
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 lighter 14000 to 20000 rated wattage generators. If you are concerned by weight, one of the champions in the above-mentioned power range is the Genmax GM17000iE, with a dry weight of just 308.6 pounds.
- With a runtime of around 10 hours under a 50% load on a full tank, the GP15000E falls within the average autonomy range among the generators of a similar power. If run time is one of your main concerns, the Westinghouse WGen14500DFc could be worth looking at. It boasts one of the highest run times among units of comparable power, lasting around 11 hours.
- While run time matters, it's heavily influenced by the fuel tank's capacity. Hence, it's important to consider fuel efficiency alongside. In terms of fuel efficiency within its wattage range, this generator falls short: it consumes approximately 1.6 GPH at a 50% load. If gasoline efficiency is at the top of your list, you may want to have a look at the Westinghouse WGen14500DFc, which has great fuel efficiency, with a gas consumption of only 0.95 gallons per hour.
