Description

Generac’s Rapid Start portable generators with PowerDial, provides back up power with the turn of a dial. The PowerDial streamlines the start-up process by putting all the controls on one convenient dial, so no more separate switches for turning on the engine, opening the fuel valve, or to adjust the choke.

Zoom on the Generac RS8000E

In a nutshell, the Generac RS8000E is a portable generator mostly geared towards:

  • Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
  • Professionals who want to ensure that a power failure will not prevent them from working

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Generac RS8000E's core is the 420 cc OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 8000W and a peak wattage of 10000W.

Its starting mechanisms include a conventional pull-start mechanism and a convenient and easy-to-use electric starter (battery included). It features Generac's PowerDial™, an easy-to-use dial with three operation settings.

With a full tank, the RS8000E can operate for around 10.5 hours at 50% load (fuel consumption around 0.71 GPH), thanks to its fuel capacity of 7.5 gallons.

Outlets

The control panel provides the upcoming 5 AC outlets:

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

As it features a twist-lock L14-30R receptacle, the RS8000E is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

Portability

The design of the Generac RS8000E is a typical, open frame, with the dimensions of L30 x W27.1 x H25.7 in, offering support and stability and enabling the possibility of raising it above ground level. The generator is designed for ideal use outdoors and in rough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 213.8 pounds. 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

The RS8000E's control panel

The control panel of the RS8000E includes a digital data center, which assists you in monitoring its status and activity, as it provides information on the lifetime run hours.

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

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Generac RS8000E, the following accessories are also included: oil, extension cord and battery charger.

Emissions

The Generac RS8000E 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 RS8000E versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Generac RS8000E compare to generators of similar power (between 7500 and 8500 W).

  • Since the generator weighs in at a dry weight of 213.8 lbs, the Generac RS8000E belongs in the expected weight range for devices which can produce between 7500 and 8500 rated watts. In terms of weight, one of the champions in their power range is the Lifan LF8750iEPL, standing at just 185 lbs.
  • Since the RS8000E boasts with a run time of around 10.5 hours at 50% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. 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 Firman H08053, with around 12 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This generator reaches an estimated fuel consumption of 0.71 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If you wish to further improve in the area of fuel efficiency, the Pulsar PG10000B16, which boasts with a gas consumption of only 0.55 GPH, may be the right generator for you.
According to our stats, the following comparison is pretty popular: Generac RS8000E vs Generac GP8000E.
