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
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • 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 design includes a gasoline-fueled 420 cc OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 8,000W and also a peak wattage of 10,000W.

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

The fuel capacity of 7.5 gallons allows the RS8000E to 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

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 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. This type of design is ideal for tough environments and heavy outdoor use.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 213.8 lbs make it incredibly difficult to manually lift and transport. Still, once it is on the ground, its wheel kit (⌀9.5") and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

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.

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Generac RS8000E also is packed along with the following accessories: oil, battery charger 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, 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).

  • Having a dry weight of 213.8 lbs, the Generac RS8000E belongs in the expected weight range for generators which produce 7500 to 8500 rated watts. In terms of weight, one of the champions in their power range is the Dewalt DXGNR8000, standing at just 183 lbs.
  • The RS8000E, offering a run time of around 10.5 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its 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 Champion 100416, with around 12.5 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. As this generator uses an estimated 0.71 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. 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.

    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

    (( 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.
