Zoom on the Generac GP15000E
In summary, the Generac GP15000E is a powerful portable generator especially useful for professionals in need of safely powering high-intensity work or lighting equipment.
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 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).
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.
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:
Additionally, it features 1 DC outlet: there's a 12V 10A receptacle with which charging your batteries is made easy.
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, because the GP15000E is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.
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. This type of design is ideal for tough environments and heavy outdoor use.
As the generator's weight is 363 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (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.
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.
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.
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 automatic low oil shut-off and an overload protection (circuit breaker), 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 therefore, can 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).
- Weight-wise, the Generac GP15000E has only 363 lbs, which renders it one of the lightest generators which produce 14000 to 18000 rated watts.
- As the GP15000E features an autonomy of around 10 hours at 50% load, it has one of the highest run times in comparison to the other generators of its power range.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This generator, with an estimated fuel consumption of just 1.6 GPH (gallon per hour) at 50% load, is one of the most fuel efficient generators, for the previously mentioned wattage range.
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.
