Description

Zoom on the Westinghouse WGen12000DF

In a nutshell, the Westinghouse WGen12000DF is a powerful portable generator mostly geared towards:

  • Professionals who want to ensure that a power failure will not prevent them from working
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

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 Westinghouse WGen12000DF in use

The Westinghouse WGen12000DF

The dual-fuel technology of the Westinghouse WGen12000DF allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 12000W and a starting wattage of 15000W. If propane-powered, it gives 10800 rated watts and 13500 starting watts.

With a noise rating of 74 dBA (just slightly more noisy than a vacuum cleaner), the generator features a convenient and easy-to-use electric starter (battery included). To add further convenience, the WGen12000DF can be remotely started (key fob included).

The running time of the WGen12000DF, with its 10.5 gallons fuel capacity, can reach up to 16 hours on a full tank of gasoline (fuel consumption around 0.95 GPH). With propane, it can reach up to 10 hours (on a 20 lbs tank - propane consumption around 0.47 GPH).

Sensitive electronics can be safely plugged in the AC outlets, as the WGen12000DF produces a clean sine wave, with a <5% Total Harmonic Disruption (THD).

Outlets

The control panel features the upcoming 7 AC outlets:

Two Duplexes 120V 20A (5-20R)
120/240V 50A (14-50R) receptacle
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle

It also sports 2 DC outlets: there's two 5V USB ports with which you may charge electronics, for example mobile phones or tablets, conveniently.

While this Westinghouse generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor. Besides, since the WGen12000DF bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Westinghouse's ST Switch Outlet

Picture of the ST Switch outlet

The ST Switch outlet

The WGen12000DF is what Westinghouse calls Smart Switch Ready. This means that it features a special outlet that allows for an automatic transfer of power in case of a power outage.

To benefit from this feature, you'll need the Westinghouse ST Switch (opens in a new tab), which is not included with the generator.

Simply put, the ST Switch is a cost-effective and versatile portable automatic transfer switch, which can be installed quickly and easily, without an electrician.

Plug the ST Switch into one of your household 120V outlets, plug your appliances to the ST Switch, and connect the WGen12000DF to the ST Switch via the special outlet and a 120V cord. The generator will automatically turn on when the power goes out, and automatically turn off when the power returns.

Portability

The Westinghouse WGen12000DF has the following dimensions: L34 x W31 x H35 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough 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 352 lbs. However, this lack of maneuverability is compensated by its wheel kit and its folding handle, with which you can conveniently shift it, once it's on the ground.

Further safety during transport, loading and unloading of the device is provided by a lift hook, which is placed on the top of the generator's frame.

Features

The WGen12000DF's control panel

The WGen12000DF's control center features a convenient meter showing you voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

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

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Westinghouse WGen12000DF's package also includes these accessories: oil, tool kit, propane hose, key fob, funnel and battery charger.

Emissions

The Westinghouse WGen12000DF is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor, so it is adequate for use in forested areas.

The Westinghouse WGen12000DF versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Westinghouse WGen12000DF compare to generators of similar power (between 10000 and 14000 W).

  • A weight of 352 lbs makes the Westinghouse WGen12000DF one of the heavier devices in the 10000-14000 rated wattage range. Regarding dry weight, one of the champions in the same power range is the A-iPower SUA13000EFI, with a dry weight of only 218 lbs.
  • With a lowest possible noise of 74 dBA, this generator places itself amongst the more quiet of the products delivering similar power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the A-iPower SUA13000EFI, whose lowest noise levels reach just 69 dBA.
  • As the WGen12000DF offers around 11 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the generators of a similar power. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Powerhorse 13000ES, reaching around 15 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. At an estimated fuel consumption of 0.95 GPH (gallon per hour) at 50% load, this generator is a rather fuel efficient one within its wattage category. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.78 GPH, the A-iPower SUA13000EFI is a device you should look out for.

Price comparison

As you can see from this interactive chart, when compared to other 10000-14000W generators, the Westinghouse WGen12000DF is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

About Westinghouse

The US based Westinghouse Outdoor Power Equipment is a legacy subsidiary of the Westinghouse Electric Corporation, founded in 1886. While the company has been acquired and merged into the American CBS, the Westinghouse name remains as the brand name for many of their electrical solutions, which stretch across the scale from power plants to portable generators – which are the main product of the Outdoor Power Equipment branch of Westinghouse. Lawn equipment, such as trimmers and blowers, is also sold under the Westinghouse brand name. All of their products are designed in the US. However, several sources report that they are in many cases manufactured in China.
