Description

Keep your family safe during power outages and natural disasters with the WEN 8,750-Watt RV and Transfer-Switch Ready Inverter Generator. The onboard inverter provides clean energy, free of voltage spikes and drops. (source: WEN (opens in a new tab))

Zoom on the WEN GN875i

In a nutshell, the WEN GN875i is a powerful portable inverter 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
  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go
  • RV travellers wishing to enhance their freedom and nomad lifestyle

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 WEN GN875i houses a 420 cc OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 7,000W along with a peak wattage of 8,750W.

This inverter generator can be started via a simple traditional pull-start mechanism, or a simple and elegant electric starter (battery included).

The fuel capacity of 4.2 gallons allows the GN875i to operate for around 6.7 hours at 50% load with a full tank (fuel consumption around 0.63 GPH).

The GN875i generates a clean sine wave: providing <1.5% Total Harmonic Distortion (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel features the following 6 AC outlets:

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

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

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this WEN generator is RV Ready. In addition, as the GN875i holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.

Portability

The WEN GN875i has a conventional, open frame design, of the following dimensions: L26.8 x W26.4 x H23.2 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.

Since the generator weighs 136.7 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Still, once it is on the ground, its set of wheels and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

Panel of the WEN GN875i

The GN875i's control panel

To help you monitor the GN875i's status and activity, its control panel is equipped with a convenient meter, which displays voltage, frequency and lifetime hours.

In addition to this info, the light indicators show you if the generator is overloaded, its oil levels are insufficient and the generator is ready.

The fuel level of the inverter generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the WEN GN875i also comes with several accessories, including: 2 altitude kits and tool kit. An official storage cover is also available, as a separate purchase.

Emissions

The WEN GN875i is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

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

The WEN GN875i versus other generators

The following charts are provided to give you an idea of how some of the key specs of the WEN GN875i compare to generators of similar power (between 6500 and 7500 W).

  • Weight-wise, the WEN GN875i has only 136.7 lbs, which renders it one of the lighter generators which produce 6500 to 7500 rated watts. If weight matters to you, one of the champions in this power range is the Sportsman GEN85KIDF with only 133 pounds.
  • Autonomy-wise, with around 6.7 hours on a full tank at a 50% load, the GN875i is on the low end when compared to other generators of a similar power 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 Generac XC6500E, with around 14 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 inverter generator reaches an estimated fuel consumption of 0.63 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If fuel consumption is your top priority, we suggest to check out the Energizer eZV7500, which has a fuel consumption of only 0.45 GPH and thus, is one of the most efficient devices in our database.

Can you retrofit a larger fuel tank or add an extended tank. I like the unit but for extended emergency operations it is a very short full tank run time. Didn't see any other options on the Wen site (Asked January 24, 2022)

It could be possible to add an extended tank, but keep in mind that gasoline is gravity-fed.

    First; Generator Bible is a fantastic site for comparing generators to fit your needs. Have owned the WEN GN875i for over a year and have used it several times during power outages lasting hours not days. Performance was great. Purchased it since my old generator is NOT and inverter and does NOT provide clean power for electronics. I decided on the WEN for the value, wattage and clean power. I have both generators in a power vented shed over 30 feet from our home so CO and noise is not a factor. The 4 year old Westinghouse is connected ONLY to our 4 ton air conditioner condensing unit through a transfer switch located by the AC. The WEN is connected to our home load center using an interlock to meet local and national codes. With this arrangement we’re able to power our whole house by limiting total watts of appliances being used simultaneously, since our range and oven are both electric. We do not have any problems with sensitive electronics while cooking as the WEN has handled the load very easily. I created a chart for us to maintain the watts below the stated run max and it isn’t difficult. I CAUTION anyone connecting generators directly to your load center or AC to follow all local and NEC codes to ensure you are legal and safe for you as well as your electric power provider repairmen. I also received approval from our electric provider on the equipment and wiring to be used during outages including 1-line electrical drawings. This takes some time and is absolutely needed in my opinion to be safe and legal. This is all a manual transfer for power during an outage but is far less expensive than an auto standby whole house generator saving us over $11,000. Another benefit is if one generator breaks, we still have one running to power some of our home and the cost to replace the broken is cheap compared to repairing or replacing a whole house generator and being in the dark until that’s completed. Customer service from WEN has been excellent, very easy to connect to the department you need and have always be given the answer or service requested. Buying direct from WEN is available, cheaper with free shipping.

    + PROS:
    • Affordable w/electric start
    • Inverter - Very low THD
    • Fuel economy VS older generator
    • Noise VS older generator
    • Weight VS older generator
    • Wire connection options
    • Customer Service
    - CONS:
    • Oil fill location
    • No GFCI outlets
    • 4.2 gallon gas tank
