Description

The GP5500 has enough power for emergency use, when you’re not using it for outdoor recreation and DIY projects.

Zoom on the Generac GP5500

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

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in outdoor fairs, festivals or events
  • Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
  • Homeowners in need of an emergency backup power for their essentials

Over the following sections, you'll uncover its power characteristics, the selection of outlets it offers, its overall portability, and the supplementary features it includes.

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 5,500W and a peak wattage of 6,875W.

This generator features a conventional pull-start mechanism.

Equipped with a 7.2 gallons fuel tank, the GP5500 ensures continuous operation for around 10 hours at 50% load with a full tank (fuel usage approximately 0.72 gallons per hour).

As the GP5500 exhibits a THD of less than 20%, which is high, it is best avoided for powering sensitive electronic devices.

Outlets

The control panel features the upcoming 5 AC outlets:

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

Since it features a twist-lock L14-30R receptacle, the GP5500 is tailored to be transfer switch ready, making it easy to connect it to your breaker box for home power support during outages.

Portability

At L27.5 x W27 x H25 in, the Generac GP5500 boasts a traditional open frame structure, ensuring stability and allowing for convenient maintenance access to components, promoting air circulation. The design is ideal for rough environments and demanding outdoor use.

With a weight of 170.9 lbs, the generator is still labeled as 'portable,' denoting its ability to be moved, although its heaviness might restrict easy portability. 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

Embedded in the control panel of the GP5500, a digital data center serves as a vital feature, offering comprehensive information on the lifetime run hours to aid in monitoring 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 standpoint, the generator is furnished with an automatic low oil shut-off and an overload protection (circuit breaker), ensuring peace of mind during operation.

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.

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).

  • At a weight of 170.9 pounds, the Generac GP5500 places in the expected weight range of the generators in the 5000-6000 rated wattage range. If you are mindful of weight, the Champion 201238 is among the top contenders in this power range, with a dry weight of 101.4 pounds.
  • Regarding its autonomy, the autonomy of the GP5500, reaching around 10 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Predator 6500, with around 14.5 hours.
  • Though run time is a significant parameter, it's closely tied to the generator's fuel tank size. To get a comprehensive understanding, fuel efficiency must also be taken into account. This generator is not fuel-efficient compared to devices of similar output: its estimated fuel consumption stands at 0.72 GPH at a 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.36 GPH, the A-iPower SUA7000L is a device you could look out for.
According to our stats, the following comparison is pretty popular: Generac GP5500 vs Generac GP6500.

Price comparison

As you can see from these interactive charts, when compared to other 5000-6000W generators, the Generac GP5500 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

    We bought our Generac 5500 in approximately 2008 or 09. We use it at our home when the power goes out, which usually happens a couple of times a year, sometimes more. As I am typing this we have been out of power for several hours and the generator is working great. It has been a good investment overall with the exception of a problem I had with it because I was using regular gasoline instead of recreational gas. Since I switched it starts and runs flawlessly and serves our needs very well. Usually starts with a pull or two. I made a wooden framed lightweight vented cover for it, set it on a cement pad, and it stays outside year round here in Michigan. For our purposes it has been a really good buy.

    + PROS:
    • inexpensive (on sale when we bought it)
    • reliable starting, pulls a little hard but starts fine
    • dependable (overall it has been great when using recreational gas instead of regular)
    - CONS:
    • had to have it repaired once (but it is 11 years old)
    • according to your review, it uses more gas than others
