Description

Zoom on the Generac GP6500

In summary, the Generac GP6500 is a portable generator especially useful for:

  • Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Professionals in need of safely powering high-intensity work or lighting equipment

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 engine, 389 cc Generac OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 6500W and reaches a peak wattage of 8125W.

This generator features a conventional 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 GP6500 is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<20%).

Outlets

The control panel features the following 5 AC outlets:

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

Because the GP6500 is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.

Portability

With its dimensions of L27.2 x W27 x H26.5 in, the conventional, open frame design of the Generac GP6500 offers stability and allows the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

Since the generator weighs 172 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). 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.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

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

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 minitgate CO poisoning. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Generac GP6500 also comes with several accessories, including: oil and funnel.

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, so it is adequate for use in forested areas.

Product Videos

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).

  • In terms of its dry weight, the Generac GP6500 stands at only 172 lbs, meaning that is one of the lighter devices of the 6000-7000 rated wattage category In terms of weight, one of the champions in their power range is the Sportsman GEN85KIDF, standing at just 133 lbs.
  • Offering around 10.5 hours of running time on a full tank at 50% load, the GP6500 is within the average autonomy range of similarly powerful generators. 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 Generac XC6500, with around 14 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. As this generator uses an estimated 0.66 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.38 GPH, the Lifan ESI 7000iER-EFI is a device you should look out for.

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 cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.
