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 houses a 389 cc Generac OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 6500W along with a peak wattage of 8125W.

This generator features 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 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

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 design of the Generac GP6500 is a typical, open frame, with the dimensions of L27.2 x W27 x H26.5 in, offering support and stability and enabling the possibility of raising it above ground level. This type of design is ideal for tough environments and heavy outdoor use.

As the generator's weight is 172 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 GP6500

The GP6500's control panel

A digital data center, one of the features of the GP6500's control panel, gives you information on the lifetime run hours, and thus, is helpful for the monitoring of its activity and status.

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

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).

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: 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).

  • As for its weight, the Generac GP6500 weighs only 172 pounds, making it one of the lighter generators in 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.
  • Given that the GP6500 reaches an autonomy of around 10.5 hours with a full tank and at 50% load, it is placed within the average autonomy range of similarly powerful generators. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Generac XC6500, reaching around 14 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 has an average fuel consumption among comparably powerful devices, as it reaches 0.66 GPH (gallon per hour) at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Lifan ESI 7000iER-EFI. With a fuel consumption of as little as 0.38 GPH, it is one of the most efficient generators currently on the market.

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.
