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.

Zoom on the WEN GN875i

In short, the WEN GN875i is a powerful portable inverter generator adequately designed for:

  • 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
  • RV travellers looking for even more independence

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, and the extra features it benefits from.

Power & Run Time

The WEN GN875i's design includes a gasoline-fueled 420 cc OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 7,000W and also a peak wattage of 8,750W.

Its starting mechanisms include a standard recoil pull-rope starting mechanism and a convenient and efficient electric starter (battery included).

The GN875i boasts a fuel tank capable of holding 4.2 gallons, allowing it to run continuously for around 6.7 hours at 50% load (with fuel usage averaging around 0.63 gallons per hour).

The GN875i produces a clean sine wave: thanks to a <1.5% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel is equipped with the following 6 AC outlets:

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

Furthermore, it has 2 DC outlets: there's two 5V USB ports providing convenient charging capabilities for mobile phones, tablets, and other electronic devices.

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this WEN generator is RV Ready. In addition, since the GN875i 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.

Portability

At L26.8 x W26.4 x H23.2 in, the WEN GN875i boasts a traditional open frame structure, ensuring stability and allowing for convenient maintenance access to components, promoting air circulation. The device has been designed for tough environments and demanding outdoor use.

Since the generator weighs 136.7 lbs, it could be potentially be difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). However, the constrained maneuverability is addressed with the assistance of its set of wheels and its folding handle, allowing for easy shifting once the generator is placed on the ground.

Features

Panel of the WEN GN875i

The GN875i's control panel

The GN875i's status and activity may be monitored conveniently via the control panel, as it features a convenient meter showing you voltage, frequency and lifetime hours.

In addition to this info, when the generator is overloaded, its oil levels are insufficient and the generator is ready, you will be informed by the featured light indicators.

Featuring a built-in fuel gauge, the inverter generator offers quick, convenient, and easy gas level checks at a glance.

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

Beyond the standard documentation and an owner's manual (opens in a new tab) to assist with setup, the WEN GN875i ships with supplementary accessories: 2 altitude kits and tool kit. An official storage cover is also available, as a separate purchase.

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).

  • As far as its dry weight is concerned, the WEN GN875i weighs just 136.7 pounds and thus, it is one of the lighter 6500 to 7500 rated wattage generators. If you are concerned by weight, one of the champions in the above-mentioned power range is the Champion 201515, with a dry weight of just 121.3 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. For those prioritizing autonomy, the Firman H07553 could be considered, as it offers one of the longest run times among generators with similar power output, reaching around 12 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. With a fuel consumption rate around 0.63 GPH (gallon per hour) at 50% load, this inverter generator is one of the more fuel-efficient models within the aforementioned wattage range. If you wish to further improve in the area of fuel efficiency, the Ford FG7750BiSRCO, which boasts with a gas consumption of only 0.5 GPH, may be the right generator for you.
According to our stats, the following comparison is pretty popular: WEN GN875i vs Champion 100520.

Price comparison

As you can see from these interactive charts, when compared to other 6500-7500W inverter generators, the WEN GN875i is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.

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.

    This inverter generator is a great option for those who want clean power for appliances and electronics. It’s 120/240 30 amp twist lock plug is used with a 30 amp to 50 amp adapter into an old 50 amp Spa tub circuit. Back fed to main panel and isolated circuits as needed. It’s easily runs all lights, electronics, refrigerator, and well pump. Long term power outages, I can isolate circuits to operate, electric water heater, 3 ton heat pump, range oven as needed but not at the same time. I chose to back feed to main panel so that I can operate any main panel circuit as needed. Make sure if you back feed you know what you are doing to keep power line workers safe from injury and that you don’t overload your generator. I also have a grid tie solar system that you must manually shut off its breaker while operating your generator. Make yourself a thorough check list for operation and use it. This generator does the job at a reasonable price and is not to heavy to move around.

    + PROS:
    • Good price point.
    • Inverter, low THD.
    • Runs everything on my all electric home including well but you must isolate breakers as needed.
    • Fuel shut off is a great bonus to run carburetor dry.
    • Oil tube for oil changes is convenient.
    - CONS:
    • Runs on gasoline only.
    • No oil filter.

    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
