Description

Zoom on the Generac GP6500

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

  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • 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

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 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 6,500W and reaches a peak wattage of 8,125W.

This generator gets running thanks to a classic hand-operated recoil starting mechanism.

With its 6.9 gallons fuel tank, the GP6500 can operate for around 10.5 hours at 50% load when fully fueled (with fuel usage averaging around 0.66 GPH).

The quite high THD (<20%) of the GP6500 makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel is equipped with the following 5 AC outlets:

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

With its twist-lock L14-30R receptacle, the GP6500 is designed to be transfer switch ready, allowing easy connection to your breaker box for powering your home during a blackout.

Portability

Measuring L27.2 x W27 x H26.5 in, the classic open frame construction of the Generac GP6500 provides stability while enabling convenient maintenance access to components and adequate air cooling. The device has been designed for tough environments and demanding outdoor use.

Despite its 172 lbs, the generator falls under the category of 'portable,' signifying its movability, although its weight may hinder easy portability. 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

To help you monitor the GP6500's status and activity, its control panel is equipped with a digital data center, giving you information on the lifetime run hours.

Featuring a built-in fuel gauge, the generator offers quick, convenient, and easy gas level checks at a glance.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you 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.

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.

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).

  • Weighing in at 172 lbs, the Generac GP6500 fits within the expected weight range for devices producing 6000 to 7000 rated watts. If weight matters to you, one of the champions in this power range is the Pulsar PGDA70BiSCO with only 118 pounds.
  • The GP6500's runtime of around 10.5 hours at a 50% load on a full tank positions it within the average autonomy range compared to other generators with similar power. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Westinghouse WGen6000, reaching around 13 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. When it comes to fuel efficiency among generators with similar wattage, this generator lags behind, with a consumption rate of 0.66 GPH at a 50% load. If you're placing a high priority on fuel consumption, the A-iPower SUA7000L, with a low fuel consumption rate of 0.36 GPH, could be an option to consider.

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

Price comparison

As you can see from these interactive charts, 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.
