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 who want to be able to use the most necessary devices in their household, even during a blackout
- Professionals who want to be able to deliver results, even during a power failure
Power & Run Time
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.
Its starting mechanism is based on a conventional pull-start mechanism.
The GP6500 can operate for around 10.5 hours at 50% load with a full tank (fuel consumption around 0.66 GPH), due to its fuel capacity of 6.9 gallons.
The quite high THD (<20%) of the GP6500 makes it unsuitable for powering sensitive electronic devices.
The control panel features the upcoming 5 AC outlets:
Since the GP6500 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.
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 device has been designed for tough environments and demanding outdoor use.
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, thanks to its wheel kit (⌀9.5") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.
Monitoring of the GP6500's status and activity is made possible by a digital data center, which provides information on the lifetime run hours and is one of the features of its control panel.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.
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 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
However, it features a spark arrestor and therefore, can 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).
- Having a dry weight of 172 lbs, the Generac GP6500 belongs in the expected weight range for generators which produce 6000 to 7000 rated watts. In terms of weight, one of the champions in their power range is the Pulsar PGDA70BiSCO, standing at just 118 lbs.
- As the GP6500 offers around 10.5 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the generators of a similar power. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Pulsar PG7500, as it provides around 13 hours.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. In fact, this generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 50% load is around 0.66 GPH. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.36 GPH, the A-iPower SUA7000L is a device you could look out for.
Here's a list of the most popular specific comparisons:
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.
