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 who know that just a short power outage could lose them hundreds of dollars
  • Professionals who want to ensure that a power failure will not prevent them from working

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 houses a 420 cc OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 8000W along with a peak wattage of 10000W.

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

With a fuel capacity of 7.5 gallons, the RS8000E may run for around 10.5 hours at 50% load with a full tank (fuel consumption around 0.71 GPH).

Outlets

The control panel includes the following 5 AC outlets:

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

Because the RS8000E is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.

Portability

The Generac RS8000E has a conventional, open frame design, of the following dimensions: L30 x W27.1 x H25.7 in, which offers support and allows it to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

As the generator's weight is 213.8 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 RS8000E

The RS8000E's control panel

Monitoring of the RS8000E'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.

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

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.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Generac RS8000E's package also includes these accessories: battery charger, oil and extension cord.

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, so it is adequate for use in forested areas.

Product Video

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 matters to you, one of the champions in this power range is the Lifan LF8750iEPL with only 185 pounds.
  • 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.
  • 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. This generator has an estimated fuel consumption of roughly 0.71 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If you wish to acquire one of the most gasoline efficient products of this power range, the Pulsar PG10000B16, with a fuel consumption of 0.55 GPH could be in your good books.
According to our stats, the following comparison is pretty popular: Generac RS8000E vs Generac GP8000E.

As you can see from this interactive chart, when compared to other 7500-8500W generators, the Generac RS8000E is on the average side of the price range.
