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 summary, the Generac RS8000E is a portable generator especially useful for:

  • Food van owners and people participating in sporting competitions, open-air performances and outdoor festivals
  • Professionals who want to be able to deliver results, even during a power failure

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 RS8000E's build contains a gasoline-fueled 420 cc OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 8000W and also a peak wattage of 10000W.

This generator can be started thanks to a simple traditional pull-start mechanism, but also to a convenient and easy-to-use electric starter (battery included). It features Generac's PowerDial™, an easy-to-use dial with three operation settings.

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

Outlets

The control panel features the upcoming 5 AC outlets:

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

As the RS8000E 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 Generac RS8000E has the following dimensions: L30 x W27.1 x H25.7 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 213.8 lbs. However, its challenging mobility is solved by a wheel kit (⌀9.5") and a folding handle, which will ease its displacement, once it is on the floor.

Features

The RS8000E's control panel

A digital data center, one of the features of the RS8000E’s control panel, gives you information on the lifetime run hours, and thus, is helpful for the monitoring of its activity and status.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

While the standard documentation and an owner's manual, 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.

Moreover, it features a spark arrestor, which makes it suitable for use 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).

  • At a weight of 213.8 pounds, the Generac RS8000E places in the expected weight range of the generators in the 7500-8500 rated wattage range. If weight is your top priority, one of the champions in this power category is the Lifan LF8750iEPL, weighing just 185 pounds.
  • With a run time of around 10.5 hours at 50% load, the RS8000E has one of the higher run times, compared to its similarly powerful peers. 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 has an average fuel consumption among comparably powerful devices, as it reaches 0.71 GPH (gallon per hour) at a 50% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse WPro8500, with a fuel consumption of 0.55 GPH could be in your good books.
