- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Professionals who want to be able to deliver results, even during a power failure
In the upcoming sections, you'll discover its power characteristics, the array of outlets it presents, its overall portability, and the additional features it possesses.
Power & Run Time
With a 298 cc Generac OHV 4-stroke engine, the Generac GP5500E operates on gasoline, providing 120/240V, with a running wattage of 5,500W and a starting wattage of 6,875W.
This generator can be started using either a standard recoil pull-rope starting mechanism or a user-friendly and efficient 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.
With a fuel capacity of 5.4 gallons, the GP5500E can run for around 10.5 hours at 50% load when the tank is full (fuel consumption is approximately 0.51 gallons per hour).
Since the GP5500E has a high THD (<20%), it is advisable to not use it for the powering of sensitive electronic devices.
Outlets
The control panel is equipped with the following 5 AC outlets:
With its twist-lock L14-30R receptacle, the GP5500E is configured to be transfer switch ready, allowing straightforward connection to your breaker box to supply backup power to your home during outages.
Portability
At L30 x W27 x H25 in, the Generac GP5500E boasts a traditional open frame structure, ensuring stability and allowing for convenient maintenance access to components, promoting air circulation. The device has been designed for tough environments and demanding outdoor use.
As the generator's weight is 163 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Nevertheless, the restricted maneuverability is counteracted by its wheel kit (⌀9.5") and its folding handle, enabling easy shifting once the generator is set in place.
Features
For easy status and activity monitoring of the GP5500E, its control panel integrates a digital data center, offering insights into the lifetime run hours.
Thanks to its built-in fuel gauge, the generator allows you to quickly, conveniently, and easily check the gas level at a glance.
Considering security aspects, the generator boasts an overload protection (circuit breaker) and an automatic low oil shut-off, offering peace of mind throughout operation.
The GP5500E 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.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Generac GP5500E's package also includes these accessories: funnel, tool kit and oil.
The Generac GP5500E versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Generac GP5500E compare to generators of similar power (between 5000 and 6000 W).
- With a dry weight of 163 lbs, the Generac GP5500E sits comfortably within the expected weight range for devices generating 5000 to 6000 rated watts. If weight is an important consideration for you, the Pulsar PGX60BiSRCO stands out as one of the top contenders in this power category, with a dry weight of 93.5 pounds.
- At a 50% load, the GP5500E's around 10.5 hours of runtime on a full tank fall within the average autonomy range for similarly powerful generators. If you wish to prioritize autonomy, the Dewalt DXGN6000 shines as one of the top contenders, offering one of the highest run times among generators with similar power output, totaling around 14 hours.
- While the run time is an important parameter, it is dependent on the fuel tank's capacity and thus, doesn't say much on its own unless we consider fuel consumption as well. When operating at 50% load, the generator's fuel consumption is estimated at 0.51 GPH, placing it within the average range of gasoline usage among similarly powerful devices. To prioritize fuel savings, we advise considering the DuroMax XP7000iHT, which stands out for its gasoline efficiency, consuming just 0.38 gallons per hour.
Price comparison
As you can see from these interactive charts, when compared to other 5000-6000W generators, the Generac GP5500E is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
