Description
Zoom on the Generac GP15500EFI
In short, the Generac GP15500EFI is a powerful portable generator adequately designed for:
- Professionals in need of safely powering high-intensity work or lighting equipment
- Prudent homeowners who want a backup power source in case of a power outage
In the forthcoming sections, you'll delve into its power characteristics, the various outlets it offers, its overall portability, and the additional features it boasts.
Power & Run Time
Generac GP15500EFI is equipped with a 816 cc Generac G-Force OVHI 4-stroke engine, running on gasoline and providing 120/240V, boasting a running wattage of 15,500W alongside a starting wattage of 19,300W.
This generator is started via an intuitive and practical electric starter (battery included).
The Electronic Fuel Injection (EFI) system enhances the engine's reliability, lowers fuel consumption, improves startup, reduces servicing, boosts stale fuel resistance, and offers better altitude adaptability.
Featuring a 14.2 gallons fuel tank, the GP15500EFI can provide power for around 11 hours at 50% load on a full tank (with fuel consumption averaging 1.29 gallons per hour).
The <5% Total Harmonic Distortion (THD) of the GP15500EFI ensures a clean sine wave output, providing a secure power source for your sensitive electronics through its AC outlets.
Outlets
The control panel is equipped with the following 7 AC outlets:
This Generac generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready. Besides, since it boasts a twist-lock L14-30R receptacle, the GP15500EFI is engineered to be transfer switch ready, ensuring easy integration with your breaker box to provide backup power to your home during outages.
Portability
At L58.5 x W30.9 x H36.5 in, the standard open frame design of the Generac GP15500EFI delivers stability alongside easy maintenance access to components and good air cooling. The featured design is ideal for the outdoors and all tough environments.
As the generator's weight is 420 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, the constrained maneuverability is addressed with the assistance of its wheel kit (⌀12") and its folding handle, allowing for easy shifting once the generator is placed on the ground.
Features
Embedded in the control panel of the GP15500EFI, a digital data center serves as a vital feature, offering comprehensive information on the lifetime run hours to aid in monitoring activity and status.
Thanks to its built-in fuel gauge, the generator allows you to quickly, conveniently, and easily check the gas level at a glance.
Regarding security, the generator comes with an overload protection (circuit breaker) and an automatic low oil shut-off, providing peace of mind during operation.
The GP15500EFI also benefits from Generac’s COsense® carbon monoxide monitoring. This technology senses and manages CO output and shuts down the unit when necessary, to protect you from CO poisoning.
In addition to the standard documentation and the user manual for prompt setup, Generac has also included accessory] in the packaging of the GP15500EFI.
The Generac GP15500EFI versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Generac GP15500EFI compare to generators of similar power (between 14000 and 20000 W).
- With a dry weight of 420 pounds, the Generac GP15500EFI finds itself in the expected weight range for generators able to produce between 14000 and 20000 rated watts. If weight is your top priority, one of the champions in this power category is the Genmax GM17000iE, weighing just 308.6 pounds.
- The GP15500EFI provides one of the highest run time among similarly powerful devices, reaching around 11 hours at 50% load.
- Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. With an estimated gasoline consumption of 1.29 GPH (gallon per hour) at 50% load, this generator is among the more fuel-efficient of the products in the above-mentioned wattage range. If minimizing fuel usage is one of your key priorities, the Westinghouse WGen14500DFc is one of the most efficient devices with similar power output, with a gasoline consumption of only 0.95 gallons per hour.
Price comparison
As you can see from these interactive charts, when compared to other 14000-20000W generators, the Generac GP15500EFI is on the expensive side of the price range.
While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.
