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 few words, the Generac GP15000E is a powerful portable generator perfectly suited for:
- Professionals who want to ensure that a power failure will not prevent them from working
- 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, and the extra features it benefits from.
Power & Run Time
The Generac GP15000E
Running on gasoline, the Generac GP15000E utilizes a 992 cc Generac OHVI 4-stroke engine to deliver 120/240V, offering a running wattage of 15,000W and a starting wattage of 22,500W.
This generator gets running thanks to a hassle-free and practical 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 high THD (<20%).
Outlets
The control panel features 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 though this Generac generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor. Besides, equipped with a twist-lock L14-30R receptacle, the GP15000E is engineered to be transfer switch ready, enabling simple hookup to your breaker box to provide backup power for your home during blackouts.
Portability
At L48.5 x W31 x H39.5 in, the standard open frame design of the Generac GP15000E delivers stability alongside easy maintenance access to components and good air cooling. The device has been designed for tough environments and demanding outdoor use.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 363 lbs make may make it challenging to manually lift and transport. Still, once it is on the ground, its wheel kit (⌀12.3") and its handle can easily solve the issue of low mobility and allow for easy relocation of the device.
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.
Features
The GP15000E's control panel
The control panel of the GP15000E includes a digital data center, which assists you in monitoring its status and activity, as it provides information on the lifetime run hours.
The inclusion of a built-in fuel gauge in the generator streamlines gas level checks for quick and convenient assessments.
Regarding security, the generator comes with an overload protection (circuit breaker) and an automatic low oil shut-off, providing peace of mind during operation.
Alongside the standard documentation and an owner's manual (opens in a new tab) for quick setup, the Generac GP15000E is bundled with additional accessories: tool kit and funnel.
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).
- Regarding its weight, the Generac GP15000E only weighs in at 363 pounds, which means it's one of the lighter generators in the 14000-20000 rated wattage range. Regarding dry weight, one of the champions in the same power range is the Westinghouse WGen14500TFc, with a dry weight of only 348.3 lbs.
- 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 WGen20000 could be worth looking at. It boasts one of the highest run times among units of comparable power, lasting 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. Among generators of similar output, this generator ranks somewhat poorly in fuel efficiency, with an estimated consumption of 1.6 GPH at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse WGen14500DFc. With a fuel consumption of as little as 0.95 GPH, it is one of the most efficient generators currently on the market.
The bottom line
