Zoom on the Generac GP15000E
In summary, the Generac GP15000E is a powerful portable generator especially useful for 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 core is the 992 cc Generac OHVI 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 15000W and a peak wattage of 22500W.
This generator gets running thanks to a simple and elegant electric starter (battery included).
With a fuel capacity of 16 gallons, the GP15000E may run for around 10 hours at 50% load with a full tank (fuel consumption around 1.6 GPH).
The quite high THD (<20%) of the GP15000E makes it unsuitable for powering sensitive electronic devices.
The control panel includes the following 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, 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. 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. 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.
In addition, the device is equipped with a lift hook on the top of its frame, which provides extra safety during the loading, unloading and transport of the generator.
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.
Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.
From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.
While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Generac GP15000E, the following accessories are also included: funnel and tool kit.
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, which makes it suitable for use 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.
- 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. This generator can be considered as one of the most fuel efficient, due to its low estimated fuel consumption of only 1.6 GPH (gallon per hour) at 50% load, within the aforementioned 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.
