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 do not wish to see their business interrupted under any circumstances
  • Homeowners in need of an emergency backup power for their essentials
  • 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 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 simple traditional pull-start mechanism and a simple and elegant 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 provides the upcoming 5 AC outlets:

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

Due to the featured twist-lock L14-30R receptacle, the RS8000E is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

The dimensions of the Generac RS8000E, which are L30 x W27.1 x H25.7 in, and its typical, open frame design provides stability and enables the generator to be raised 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. However, this lack of maneuverability is compensated by its wheel kit (⌀9.5") and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the Generac RS8000E

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.

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

Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Generac RS8000E also comes with several accessories, including: battery charger, extension cord and oil.

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.

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 Dewalt DXGNR8000, weighing just 183 pounds.
  • The RS8000E, falls within the average autonomy range compared to generators of a roughly same power, with a run time of around 10.5 hours at a 50% load and a full tank. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Champion 100416, which is able to run for around 12.5 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 not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Pulsar PG10000B16. With a fuel consumption of as little as 0.55 GPH, it is one of the most efficient generators currently on the market.

    (( Generac RS8000E )) Bought 08/22/2020 Great price considering it includes a 25′ Three Way Extension Cord & Oil for the crankcase. I start the Generator every month for 30 min. The Rapid Starter has worked great every time & is simply to operate. The charger that comes with the generator has an Out-Put of 14 volt so it’s more of a battery maintainer. If you are using it as a charger, it will take a couple days to recharge your battery. I use my regular Battery Charger & it only takes an hour to charge it. The included charger is nice for those that don’t have a standard battery charger. I haven’t used my generator since the Mid-West Derecho but it’s ready to go at all times..

    + PROS:
    • The Generac RS8000E is compact and the right size to run your house essentials in an emergency. It Starts & runs great. If you have any question about your Generac Generator. Their Help number is printed on the generator.
    - CONS:
    • Some Generac Generators come with a Fuel Shut-Off. This model does not so I had to add my own. That way I can shut the gas off from the tank and drain the Carburetor for storage so I don't have to start it every month. Also I wish it would have came with a dust cover.

    I bought the rs8000e after a 30 hour outage in 20 degree temperatures. I took initially could not start. The problem was that I didn’t wire the fully charged battery. After that senior moment was discovered, it started up right away. I
    wanted too avoid the gasoline/carburetor problem so I bought a propane conversion kit made for the rs8000e. Installs easily and no maintenance emptying the gasoline for storage.

    + PROS:
    • Very well built, reliable and easy to set up.
    - CONS:
    • None
