Description
From emergency home backup to DIY projects to the jobsite, the Generac GP15500EFI portable generator provides high wattage, dependable portable power.
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
- Small homeowners in search of a full power backup solution
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
The Generac GP15500EFI
Running on gasoline, the Generac GP15500EFI utilizes a 816 cc Generac G-Force OVHI 4-stroke engine to deliver 120/240V, offering a running wattage of 15,500W and a starting wattage of 19,300W. The impressive running wattage makes this unit the 3rd biggest portable generator currently on the market.
Its starting mechanism is based on a practical and straightforward 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.
The GP15500EFI's fuel tank, boasting 14.2 gallons, allows it to operate for around 11 hours at 50% load with a full tank (with an estimated fuel consumption of 1.29 GPH).
With a <5% Total Harmonic Distortion (THD), the GP15500EFI delivers a clean sine wave—essential for safeguarding your delicate electronics when plugged into its AC outlets.
Outlets
The control panel provides the upcoming 7 AC outlets:
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 GP15500EFI is engineered to be transfer switch ready, enabling simple hookup to your breaker box to provide backup power for your home during blackouts.
Portability
Measuring L58.5 x W30.9 x H36.5 in, the classic open frame build of the Generac GP15500EFI delivers stability and easy maintenance access to components, facilitating air circulation. The design is ideal for rough environments and demanding outdoor use.
With a weight of 420 lbs, the generator is still labeled as 'portable,' denoting its ability to be moved, although its heaviness might restrict easy portability. Nevertheless, the restricted maneuverability is counteracted by its wheel kit (⌀12") and its folding handle, enabling easy shifting once the generator is set in place.
Features
The GP15500EFI's control panel
The control panel of the GP15500EFI includes a digital data center, which assists you in monitoring its status and activity, as it provides information on the lifetime run hours.
The built-in fuel gauge of the generator ensures simple and quick gas level assessments.
Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.
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.
Alongside the typical set of documentation and owner's manual (opens in a new tab) to assist with setup, Generac has included some oil 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).
- As far as its dry weight is concerned, the Generac GP15500EFI weighs just 420 pounds and thus, it is one of the lighter 14000 to 20000 rated wattage generators. If weight is an important consideration for you, the Westinghouse WGen14500TFc stands out as one of the top contenders in this power category, with a dry weight of 348.3 pounds.
- Among its devices with similar power, the GP15500EFI offers one of the highest run times, running for around 11 hours at 50% load.
- While run time is vital, it hinges on the fuel capacity. To grasp the full picture, we must also factor in fuel efficiency. Among generators of similar power, this generator stands out with a better fuel efficiency than most, with consumption rates around 1.29 GPH (gallon per hour) at 50% load. If you're placing a high priority on fuel consumption, the Westinghouse WGen14500DFc, with a low fuel consumption rate of 0.95 GPH, could be an option to consider.
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.
