WEN DF451i - 3500/4500W Dual Fuel Inverter Generator

In a nutshell, the WEN DF451i is a quiet and compact portable inverter generator mostly geared towards:

• RV travellers looking for even more independence
• People occasionally participating in sporting competitions, open-air performances and outdoor festivals
• Handcrafting enthusiasts who wish to work on-the-go
• Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
• Tailgating and campground aficionados with the desire of enjoying power anywhere they go

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 dual-fuel technology of the WEN DF451i allows for an output of 120V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 3,500W and a starting wattage of 4,500W. If propane-powered, it gives 3,150 rated watts and 4,500 starting watts. Additionally, as the generator is parallel capable (parallel kit not included), it can be linked to a second unit for more power.

WEN’s Auto Fuel Selection technology automatically selects the fuel source (LPG or gasoline) depending on availability and prioritizes LPG. Thus, if a propane tank with enough LPG is connected, the generator will automatically use LPG. If no propane tank is connected, or if there is not enough LPG remaining in the tank, the generator will use gasoline.

The inverter generator is rated for a noise of 58 dBA (less noisy than a conversation at home). Its starting mechanisms include a simple traditional pull-start mechanism and a simple and elegant electric starter (battery included).

With a fuel capacity of 2.2 gallons, the DF451i can operate for around 8.5 hours at 50% load using gasoline (fuel consumption around 0.26 GPH), or for around 9 hours (on a 20 lbs tank - propane consumption around 0.52 GPH) using propane.

Sensitive electronics can be safely plugged in the AC outlets, as the DF451i produces a clean sine wave, with a <1.2% Total Harmonic Distortion (THD).

Outlets

The control panel includes the following 3 AC outlets:

Additionally, it features 3 DC outlets: there's a 12V 8A (cigarette lighter style) receptacle allowing you to easily charge your batteries and two 5V USB ports (USB-A) with which charging of electronics like mobile phones and tablets is made convenient.

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this WEN generator is RV Ready.

Portability

The WEN DF451i's characteristic encased inverter generator design (L23.2 x W18 x H20.1 in), provides an esthetical advantage over any ordinary, open frame product. The design follows the contemporary trends and is perfect for recreationally generating power.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 100 pounds. However, this lack of maneuverability is compensated by its set of 2 wheels and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

The DF451i's control panel

One of the many DF451i's features is the data center, included in its control panel, which conveniently provides information on the frequency, fuel level, voltage, lifetime run hours and power output and thus, helps you monitor its activity and status.

In addition to this info, the device’s light indicators will display if the oil level is too low, the generator is ready and the generator is on overload.

The fuel shutoff feature turns off the flow of fuel, allowing for the DF451i to use up the remaining fuel from the carburetor before automatically shutting down. This helps fight the build-up and blockages caused by stagnant fuel inside the carburetor, minimizing maintenance while prolonging the unit’s lifespan.

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

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the WEN DF451i also comes with several accessories, including: tool kit, propane hose and funnel.

Emissions

The WEN DF451i is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor, which makes it suitable for use in forested areas.
