Zoom on the WEN GN875i

In a few words, the WEN GN875i is a powerful portable inverter generator perfectly suited 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
  • Camping and tailgating buffs looking to enhance their experience
  • RV travellers who wish to upgrade their experience to another level

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.

Power & Run Time

Featuring a 420 cc OHV 4-stroke engine, the WEN GN875i operates using gasoline, providing 120/240V, with a running wattage of 7,000W and a starting wattage of 8,750W.

Equipped with a simple traditional pull-start mechanism and a no-fuss and convenient electric starter (battery included), this inverter generator provides versatile starting capabilities.

The GN875i's fuel tank, with a capacity of 4.2 gallons, supports uninterrupted operation for around 6.7 hours at 50% load when fully fueled (fuel consumption at an estimated 0.63 gallons per hour).

As the GN875i produces a clean sine wave, with a <1.5% Total Harmonic Distortion (THD), sensitive electronics may be plugged in the AC outlets safely.

Outlets

The control panel includes the following 6 AC outlets:

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

Furthermore, it showcases 2 DC outlets: there's two 5V USB ports enabling convenient charging of devices like mobile phones and tablets.

With its TT-30R receptacle (TT as in 'Travel Trailer'), this WEN generator is RV Ready. In addition, with its twist-lock L14-30R receptacle, the GN875i is configured to be transfer switch ready, allowing straightforward connection to your breaker box to supply backup power to your home during outages.

Portability

At L26.8 x W26.4 x H23.2 in, the traditional open frame structure of the WEN GN875i ensures stability while facilitating convenient maintenance access to components and promoting air cooling. The featured design is ideal for the outdoors and all tough environments.

Even at 136.7 lbs, the generator is categorized as 'portable,' suggesting its movability, although its weight impede its portability. Despite the restricted maneuverability, its set of wheels and its folding handle provides a solution, allowing for convenient shifting once the generator is positioned on the ground.

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, offering voltage, frequency, and lifetime hours readings.

In addition to this info, the generator's light indicators provide visual feedback when the generator is on overload, the oil level is too low and the generator is ready.

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

As far as security is concerned, the generator comes with an automatic low oil shut-off and an overload protection (circuit breaker), providing peace of mind during use.

Apart from the standard documentation and an owner's manual (opens in a new tab) to facilitate setup, the WEN GN875i features extra 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).

  • 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. Weight-conscious users may find the Sportsman GEN85KIDF appealing, as it is one of the top contenders in this power range, weighing just 133 pounds.
  • As for its autonomy, the GN875i, with an autonomy of around 6.7 hours at a 50% load, is placed on the low end among the generators of its kind. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Predator 9000, as it provides around 13 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 is one of the more fuel-efficient options in its power range, consuming approximately 0.63 GPH (gallon per hour) at 50% load. If you wish to further improve in the area of fuel efficiency, the Cummins Onan P9500df, which boasts with a gas consumption of only 0.6 GPH, may be the right generator for you.

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
