Description

Zoom on the Generac GP6500

In a nutshell, the Generac GP6500 is a portable generator mostly geared towards:

  • 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
  • Professionals who want to ensure that a power failure will not prevent them from working

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 GP6500 in use

The Generac GP6500

The Generac GP6500'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 6,500W and a peak wattage of 8,125W.

This generator is started via a simple traditional pull-start mechanism.

With a full tank, the GP6500 can operate for around 10.5 hours at 50% load (fuel consumption around 0.66 GPH), thanks to its fuel capacity of 6.9 gallons.

The powering of sensitive electronic devices with the GP6500 is not recommended due to its high THD (<20%).

Outlets

The control panel includes the following 5 AC outlets:

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

As the GP6500 holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.

Portability

The Generac GP6500 has the following dimensions: L27.2 x W27 x H26.5 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 172 lbs. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀9.5") and its folding handle, once it is placed on the ground.

Features

Panel of the Generac GP6500

The GP6500's control panel

One of the many GP6500's features is the data center, included in its control panel, which conveniently provides information on the lifetime run hours and thus, helps you monitor its activity and status.

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

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

The GP6500 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.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Generac GP6500 also is packed along with the following accessories: funnel and oil.

Emissions

The Generac GP6500 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.

The Generac GP6500 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Generac GP6500 compare to generators of similar power (between 6000 and 7000 W).

  • At a weight of 172 pounds, the Generac GP6500 places in the expected weight range of the generators in the 6000-7000 rated wattage range. If weight is your top priority, one of the champions in this power category is the A-iPower SUA7600iED, weighing just 130 pounds.
  • The GP6500, offering a run time of around 10.5 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its peers. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Westinghouse WGen6000, as it provides around 13 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. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.66 GPH at a 50% load. If you wish to further improve in the area of fuel efficiency, the A-iPower SUA7000L, which boasts with a gas consumption of only 0.36 GPH, may be the right generator for you.

Here's a list of the most popular specific comparisons:

Price comparison

As you can see from this interactive chart, when compared to other 6000-7000W generators, the Generac GP6500 is on the average side of the price range.

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