Zoom on the Generac GP17500E

In summary, the Generac GP17500E is a powerful portable generator especially useful for:

  • Professionals who want to ensure that a power failure will not prevent them from working
  • Small homeowners in search of a full power backup solution

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 GP17500E in use

The Generac GP17500E

The Generac GP17500E houses a 992 cc Generac OHVI 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 17500W along with a peak wattage of 26250W.

This generator gets running thanks to a simple and elegant electric starter (battery included).

The fuel capacity of 16 gallons allows the GP17500E to operate for around 10 hours at 50% load with a full tank (fuel consumption around 1.6 GPH).

The GP17500E is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<20%).

Here are a few examples of what this generator could allow you to simultaneously power:Note: All of these devices might not start simultaneously. Provided examples are based on a maximum load of 75 % and estimated wattages. With the help of our wattage calculator you can find out if this product suits your requirements.

Outlets

The control panel features the upcoming 8 AC outlets:

Duplex 120V 20A (5-20R) GFCI
Duplex 120V 20A (5-20R)
Two 120V 30A (L5-30R) receptacles
120/240V 30A (L14-30R) receptacle
120/240V 50A (14-50R) receptacle

In addition, it provides 1 DC outlet: there's a 12V 10A receptacle with which charging your batteries is made easy.

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, since the GP17500E 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 Generac GP17500E has a conventional, open frame design, of the following dimensions: L48.5 x W31 x H39.5 in, which offers support and allows it to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

As the generator's weight is 390 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Never less, it can still be moved quite conveniently with the help of a wheel kit (⌀12.3") and a handle, once it is placed on the ground.

A lift hook, which is on the top of the frame, serves as an extra safety feature for the transport, unloading and loading of the device.

Features

The GP17500E's control panel

The control panel of the GP17500E includes an illuminated data center, which assists you in monitoring its status and activity, as it provides information on the lifetime run hours.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

Besides the usual set of documentation and user manual to get you promptly started, Generac also included a tool kit in the GP17500E's packaging.

Emissions

The Generac GP17500E is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

Moreover, it features a spark arrestor and therefore, can be used in forested areas.

The Generac GP17500E versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Generac GP17500E compare to generators of similar power (between 10000 and 17500 W).

  • Considering its dry weight of 390 pounds, the Generac GP17500E is one of the heavier generators producing between 10000 and 17500 running watts. If weight is your top priority, one of the champions in this power category is the A-iPower SUA13000EFI, weighing just 218 pounds.
  • With a run time of 10 hours at 50% load, the GP17500E has one of the higher run times, compared to its similarly powerful peers. 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 Cat RP12000 E, with 11.7 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. This generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 1.6 GPH at a 50% load. If you wish to further improve in the area of fuel efficiency, the A-iPower SUA13000EFI, which boasts with a gas consumption of only 0.78 GPH, may be the right generator for you.

Price comparison

As you can see from this dynamic chart, when compared to other 10000-17500W generators, the Generac GP17500E is on the average side of the price range.

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

The bottom line

STRENGTHS:
  • In the expected price range
  • Electric start
  • High run time
WEAKNESSES:
  • No recoil back-up
  • No remote start
  • Not CARB-compliant
  • On the heavy side (390 lbs)
  • Low fuel efficiency
