Description

The GP5500 has enough power for emergency use, when you’re not using it for outdoor recreation and DIY projects. (source: Generac (opens in a new tab))

Zoom on the Generac GP5500

In summary, the Generac GP5500 is a portable generator especially useful for:

  • RV travellers looking for even more independence
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners in need of an emergency backup power for their essentials

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 GP5500 in use

The Generac GP5500

The Generac GP5500's core is the 389 cc Generac OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 5500W and a peak wattage of 6875W.

Its starting mechanism is based on a conventional pull-start mechanism.

The GP5500 can operate for around 10 hours at 50% load with a full tank (fuel consumption around 0.72 GPH), due to its fuel capacity of 7.2 gallons.

Since the GP5500 has a somewhat high THD (<20%), it is advisable to not use it for the powering of sensitive electronic devices.

Outlets

The control panel includes the following 5 AC outlets:

Two Duplexes 120V 20A (5-20R)
120/240V 30A (L14-30R) receptacle

Since the GP5500 bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

The design of the Generac GP5500 is a typical, open frame, with the dimensions of L27.5 x W27 x H25 in, offering support and stability and enabling the possibility of raising it above ground level. The featured design is ideal for the outdoors and all tough environments.

As the generator's weight is 170.9 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, its challenging mobility is solved by its wheel kit (⌀9.5") and its folding handle, which will ease its displacement, once it is on the floor.

Features

Panel of the Generac GP5500

The GP5500's control panel

A digital data center, one of the features of the GP5500’s control panel, gives you information on the lifetime run hours, and thus, is helpful for the monitoring of its activity and status.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

Besides the usual set of documentation and owner's manual (opens in a new tab) to get you promptly started, Generac also included some oil in the GP5500's packaging.

Emissions

The Generac GP5500 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor and thus, may be used in forested areas.

Product Video

The Generac GP5500 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Generac GP5500 compare to generators of similar power (between 5000 and 6000 W).

  • As its weight is 170.9 pounds, the Generac GP5500 falls in the expected weight range of the devices in the 5000-6000 rated wattage category. If weight matters to you, one of the champions in this power range is the Westinghouse WGen5300v with only 107 pounds.
  • As far as autonomy is concerned, providing around 10 hours of runtime with a full tank at a 50% load, the GP5500 falls into the low end in comparison with other devices of a comparable power output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Cat RP5500, boasting with around 15 hours.
  • 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 is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.72 GPH at a 50% load. If you wish to further improve in the area of fuel efficiency, the Westinghouse WGen5300v, which boasts with a gas consumption of only 0.35 GPH, may be the right generator for you.
According to our stats, the following comparison is pretty popular: Generac GP5500 vs Generac GP6500.

Price comparison

As you can see from this interactive chart, when compared to other 5000-6000W generators, the Generac GP5500 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.
