Description

Remember when you kept the lights on? 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. Our 420cc 4-stroke OHV engine produces up to 8750 surge watts and 7000 rated watts of power, making this the perfect backup generator in case of emergencies. Designed to mirror a pure sine wave, this unit limits total harmonic distortion to under 0.5 percent at no load and under 1.5 percent at full load, making it safe to run laptops, cellphones, monitors, tablets and other sensitive electronics. Our ultra-efficient 4.2-gallon tank provides up to 6.7 hours of half-load run time. The fully- packed panel comes equipped with two three-prong 120V NEMA 5-20R receptacles, two 5V USB ports, one 120V/240V transfer-switch-ready NEMA L14-30R twist lock receptacle, and one 120V RV-ready TT-30R receptacle. Maximize fuel economy and runtime by engaging the eco-mode switch. This allows the generator's engine to automatically adjust its fuel consumption as items are plugged into and unplugged from the panel, minimizing noise and fuel usage whenever possible. The lightweight body weighs 30% less than a traditional 8750-watt generator, while the included wheel and handle kit makes for easy transport and storage between uses. The panel’s data meter monitors the voltage, frequency, total runtime, and session runtime. Low-oil shutdown, combined with the built-in overload protection and indicator lights, safeguard both your generator and your electronics from damage. And because it’s a WEN product, your open frame inverter generator comes backed by a two-year warranty, a nationwide network of skilled service technicians, and a friendly customer help line, all to make sure you remember WEN.

    • Strong and reliable generator for mobile detailing
Style: 4500W Dual Fuel + CO Alarm + Electric Start

The media could not be loaded. We bought this generator for my husband’s mobile detailing setup, and it has been working great. It has strong, steady power and starts quickly with the electric start. The build quality feels solid, and the wheels make it easy to move when needed. Assembly was simple and everything was ready to use right away. I added photos and a video to show how it runs. The noise level is reasonable for this size, and the generator handles all of his detailing equipment without any issues. It feels durable, has good capacity, and the features are very straightforward. A dependable, well-made generator that works exactly as expected. ... show more

    • First unit defective. Replacement unit sent. Performs as expected. I would purchase again.
Style: 8750W + Electric Start
WEN GN875i open frame inverter generator Unit is loud. WEN technical/customer service support is available in The States via an 800 telephone number from the owner’s manual though wait queue on my four calls averaged twenty minutes. No ticket number was assigned. However, that didn’t seem to be a problem on subsequent calls. Perhaps my telephone number was logged and used to identify me and access my previous conversations. NOTE: WEN uses an automated system to field your call offering the option of holding, noting the number of people queued in front of you, or leaving your telephone number for a call back. The convenience of leaving a call back number could be outweighed by the slower response of the call back, which in my case was well over 24 hours, depending on your circumstances. Product and return knowledge varied from excellent to poor depending on the representative I spoke to. The first unit arrived on time enclosed in a plastic bag inside of a single walled corrugated cardboard carton lined on all six sides with ¾” foam. The carton had a puncture and resulting 2” tear. Total wt. of the shipment was 147 lbs. per the FedEx label. I found the packaging to be inadequate. The tubular frame was bent near a wheel axle mount point resulting in the axle tracking about 15° off center. I used a couple of 4x4’s two screws and a bottle jack to return the frame to its original position, leaving only a dent and scuff mark from the impact that caused the damage. I found tipping the unit on its side facilitated the removal of the shipping brackets. Final assembly, i.e., axles, wheels, feet, handle and connecting the ground terminal wire to the battery was straight forward using only the supplied tools and owner's manual. After engine break in – 30W oil, no load, one hour run time: The engine coughed and died each time a larger load demand was called for, e.g., well pump and miter saw, though it had no problem with the fridge compressor or lights, tv, ceiling fans, etc. After diagnosing the trouble as a potentially bad carburetor stepper motor, WEN support told me to contact Amazon to make return arraignments. However, when I pulled up my order on Amazon I found requests for return directed me to the seller, WEN, as Amazon does not allow product with oil and/or gasoline to be sent to them (even residual amounts). A call back to WEN had me going back and forth with one of their tech/svc people. He telling me he had no way of helping with a return since Amazon made the sale. Me telling him that Amazon clearly states they do not allow items with gas and or oil in them to be sent to any of their facilities and to contact the seller. He telling me Amazon puts that up to deter returns, but if I actually spoke to an Amazon representative they’d give me a return code to use. Me telling him (again) Amazon clearly states, for safety reasons, they do not allow this type of product sent to them. He putting me on hold. He coming back on the line and offering me the option of sending the unit to WEN outside of Chicago or to carry it to a local -to me- authorized WEN repair outfit. I chose the former. He emailed me a return label. Unfortunately, I did not realize that I needed to contact the carrier for pickup, thinking that the creation of the label notified the carrier (FedEx Ground) of the need for a pickup. Another call to WEN cleared this up for me. Exactly one week later, WEN tech/svc called telling me they did not have the parts necessary to repair the unit I had sent them, but offered to either cannibalize a new unit to make the repairs or to simply send a new unit. I chose the latter. A week later, the replacement unit arrived. Again, there was a puncture through the carton, but only minor cosmetic damage was the result. The oil fill plug was not threaded back into the engine tightly enough at the factory, causing residual oil to coat a good portion of the unit. Although the handle is shipped inside of bubble wrap it is put in an opening between the engine and inverter. I’m assuming, sharp edges inside of the unit cut the foam on the handle in two places. The same damage occurred in the original shipment as well. Two cuts on the foam handle. This time I tested the generator after engine break in but before putting the wheel kit, feet and handle on by spinning up a miter saw that draws 18 AMPS at start up. The engine and generator performed flawlessly. I subsequently put the wheels and handle on, grounded the unit and plugged it into a Reliance 10 circuit 7500W transfer switch (excellent product btw) and have run the fridge, well pump, three ceiling fans, a blender, basement, kitchen and bedroom lights and an air fryer simultaneously. When demand is called for the engine and generator immediately respond. I couldn’t be more pleased. The unit is loud, reading 82dB at 20’ using an uncalibrated freeware app on my iPhone. As to packaging, UPS Small Parcel and FedEx Ground have a 150 lb. weight limit which suggests more robust packaging is not an option (GNi875 shipping weight +/- 147 lbs) for WEN, unless they ship via a more expensive mode. The tech/svc person I dealt with said that one in ten of the GN875i units were being damaged in transit; so chronic a problem that they were offering credits up to $100.00 on units that arrived damaged. I’m on the East Coast in the USA the unit shipped from California, so my units probably experienced more transfers than most do. ... show more

    • Great generator but loud

Review Image by Brad Kuhn Brad Kuhn
I bought this after losing my river cabin to a tornado. I was able to wire up my deck and bunkhouse to a generator who demolition and construction happened. For 5 days, I ran this Wen open frame inverter generator, powering my mini-split, lights and water pump to my make shift cabin. The generator ran flawless, only powering it down once a day to check oil and refuel. With a 30-50%load, it would run 8-9 hours on a tank of gas. At night, temps got down into the 30’s so I ran my 12,000 mini split for heat and got 11 hours out of a tank. When I gassed it up at 7AM, it’s was nearly empty! My only complaint was noise, I planned to keep the genny under the deck while I worked and slept but due to exhaust noice, I grabbed a new 100’ extension cord and moved it as far away from the cabin as possible. When I’m done rebuilding, this generator will work construction for the rest of its life. Would I buy again? Probably not, I’d spend $150 more and get an enclosed inverter generator which operates 10-15 db quieter than this set up. But if low cost is what your after, this is a great candidate for price and reliability!! Update! This generator not has about 500-hrs on it and is a work horse! While I stand by my words about noise, I’ve been using it 24-hrs a day to run power tools, compressor, and a mobile AC unit in my new cabin I’m building. Just got home from a 7-day build and I only shut it off twice. ... show more
