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.

For the Wen GN875i - As of Nov. 2024 they seem to have resolved packaging issue and mine arrived undamaged. The manual is pretty good. I added one quart of 5W-30 Synthetic and that seemed to fill it up. The manual said the starting battery needed to be connected and it was at the terminals but there is a plug tie-wrapped and tucked up inside that I missed so when the electric start didn't work I thought it was because the battery was dead. Later, when I looked closer, getting ready to charge it I saw the plug. Once connected it worked. The generator is very easy to start if you follow the procedures printed on the card attached to the unit. After filling with non-ethanol gas, opening fuel flow, turning on the run switch and giving it choke, it almost started the first pull. It started and ran non-stop on the second pull. Not sure how they made it so easy to pull-start. I didn't really need the electric start. I have never broken in a small gas engine on any other gas-powered equipment but I followed break-in procedures for this 13 HP 420cc engine using two space heaters, a box fan and an electric charcoal starter. No load the first hour, then small loads the second hour, then varied loads totaling less than half the rated power. During the first hour there were regular pops/sputters that I think was caused by fuel blowing past the piston rings and backfiring in the exhaust. The backfires subsided in the second hour and it was running very smooth after 4 hours. The purpose of the break-in is to properly seat the piston rings. I am glad I ordered the WEN magnetic oil dip-stick for $10 to use for the break-in. It collected a blob of fine metal powder during the 8-hour first run. Eco-Mode was good for smaller loads but the engine ran at full rpm with Eco on or off with a 40%+ load. A full tank of gas (4.2 gallons?) lasted more than 7 hours with light-medium loads. Changing the oil was easy but I had to set it up on wood blocks to get it high enough to flow into a small container. At 135 pounds it is very heavy but the wheels and handle that you attach to the generator (assembly required) allow it to be moved around without any problem even going up a step at a doorway. There is no way one average person could dead lift this into a truck or trunk of a car but a ramp would work for a pickup. I compared this unit to the same size inverter generator at Harbor Frt. and they appear VERY similar in overall construction and features. Maybe the same factory? The WEN was $300 less and I feel like it was a great value. You can tell that it was designed and manufactured with quality in mind. Haven't tried near maximum loads yet but I am optimistic.

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.

This will be a somewhat longer review... We are in Oregon and lost power for 6.5 days during the ice storm a few weeks ago.... I have a unique setup at my house, and have multiple dwellings. And my water pump feeds from a different panel... So I already own 4 generators before I bought this one... One Honda, 6000surge, 5000 rated. A predator(harbor freight) 4000/3500, Honda eu2000 inverter, and Yamaha 2000 inverter... My Honda 5000 would run my hot water heater and freezer, and that was it. The Honda 2000 was plugged into the tv, and ran all the other sensitive electronics.... I always worry about using a non inverter generator for the expensive TV and stuff... So when I saw this thing I was SUPER impressed with its stats... 8750 peak, 7000 running on an inverter generator... I already have an interlock kit and 30 amp breaker... 7000/240 comes out to 29 amps. Perfect.... This thing will run my pellet stove, fridge, and freezer, lights, and the hot water heater. All at the same time I think.... So I will go into my thoughts on the generator. So I got this after the power was back on, so I will be ready for next time... It has not been hooked up to the house yet... Pros. Seems well built, voltage and freq dead on...60hz. Measured with my fluke meter.. Came with battery, electric start is pretty sweet. nice big tires to roll it around, its heavy. All the outlets you need, 4 prong, and 3 prong for camper. Inverter, so good for your TV, expensive fridge, laptop, cable box, etc... Oil drain has a hose attached, so oil changes will be EASY. Also came with a funnel with flex tube on it. Cons... Didn't come with a bottle of oil...That would have been nice. Not a huge deal. After it was set up, I rolled it outside and ran it for a few hours with a light load on it. Then when I went to roll it back in the bracket for the pull handle broke off... This really bummed me out, but I called WEN customer service and got someone on the phone pretty fast, and he set me up with the new part. Very easy, and good customer service... Its not here yet, but I will update if it doesn't show up... Its not quiet... Its like a regular generator, so dont expect this thing to be like quiet for camping. But thats not what I bought it for. I would buy again, and I will update this review as I go along. Also, I popped for the extended 4 year warranty from amazon... It was just over 100 bucks, and I think its worth it. Feel free to ask questions, and I will answer honestly. I paid full price for this generator, I'm not one of those guys who gets paid to write good reviews. :) UPDATE--- The first bracket that Wen sent me got lost in the mail.(not their fault), called them up and they said no problem, and sent a new one. It got here pretty quick. Then after another month, the original one got found and showed up. So I have a backup now. LOL. I have not used this generator to run the house yet because we have not had another storm. But I start it once a month and let it run for a little while, and it always starts up and runs like a top... Good voltage, good frequency...

This generator has been a life saver when living out in the woods where the local electric co-op goes down "due to maintenance" for periods of 8-24hr periods 1-2 times a month and the ever present threats of hurricanes. After following the break in procedures, it's proved itself very reliable where it'll start right up all the time, every time. It's easy to use and the versatility of it being a whole home generator/inverter along with the ability to load it on a trailer for power tools out in the fields makes it a winner. When using as a whole home generator, it powers an old not energy efficient fridge, 2 mini-split air conditioners (one 240v dual head and one 120v), a heat pump water heater, well pump, microwave, coffee maker, tv and various electronic gadgets. On eco-mode, it stays on low rpm's with the ac's, fridge and water heater running. I can hear the engine rev up when the coffee maker, microwave or the well pump flip on but only for a short while. Probably due to the electrical surge but it revs back down pretty quickly afterwards. Also on eco-mode, I've ran it continuously for 6-8 hour intervals on a full tank of gas with all of the aforementioned running. Two things I wish it had are 4 wheels instead of just two in the back to make it easier to move around as it can be pretty heavy with a full tank of gas. And I wish it had a remote start or at least the option to add one to it. Other than those, the generator has been very reliable, powerful and the best feature is the inverter design where it provides clean electricity to the house. I've had it for about a year and it hasn't let me down once. Hope it stays that way!

UPDATE: See Below………. Purchased last January. Hard to find a generator that isn’t made in China, or has parts made in China. Was recommended by my electrician who has a WEN and loves it. WEN is a midwestern comoany that’s been around since the 1950s. Their generators are engineered in the US but built in China under WEN’s supervision. This generator’s price was excellent as I paid $899 delivered. This has both pull and electric start. The battery is not connected, so I’ll have to connect and charge it. Manual directions are just adequate. Oil fill is in a very awkward position so they provide you with a funnel and clear tube. Many instruction steps do not include pictures. Gas valve needs to be turned into the “ON” position for several minutes before starting. She ran well and steady and there was no flicker when I tested. Running furnace, hot water heater, well pump, microwave, lights in the kitchen and living room. I did call their customer service line with a question, waited about 10 minutes and a pleasant person from the mid-west answered all my questions.. A week after purchasing it was 17 degrees (F) outside and went to start the generator by pull start. Tried several times after waiting 5 minutes from opening up the fuel line. No luck. Waited. tried several more times and finally got it going. Real pain in the ass. Glad I got electric start. Ran 45 minutes to charge the new battery. Shut down then tried the electric start. Started right up. I like it for the price, plenty powerful, but she should start up by pull a lot easier in cold weather. It’s now a year later and while the pull cord is smooth she won’t start in cold weather, even with electric start. Each time I have to remove the spark plug, put a little gas in the carburetor, then reconnect the spark plug. Then she starts right up. Callled WEN again and they said to take it to an authorized dealer in New Hampshire, both names they gave me were 2 hours away. I called and one business is shut down and the other never called back and I think they’re out of business too. It’s probably a defective carburetor, and they said they’d replace it, but now I have to take it somewhere locally where I’ll have to pay the labor costs even though it’s still under warranty. We’ll see…. Update 1/23/26: WEN recommended I take to a local local small engine shop to diagnose and fix. $121.00 later they said it was a missing spring in the choke, and now it starts right up. Great. But now the ECO switch under the choke switch doesn’t work so I have to take it back again. Because there is NO authorized deals to work on this under their warranty I have to pay out of pocket. I took a chance on WEN, and I’ve been patient, but I’ll never buy a WEN product again. I’ll suck it up and spend the extra for a Honda.

Thought the reviews with the bent frame were anomalies, but sure enough, I got a slightly bent frame, otherwise everything else looks good. I contacted WEN to tell them their factory is bending frames then boxing the generator. They told me to contact Amazon about either a return or a possible discount. I did and they were fantastic. Offered a very generous discount or a return with a pickup at the house, I would not have to cart it back to UPS. I opted for the discount. I haven't even turned it on yet, but I can say the machine is sleek and compact. Looking forward to putting it through it's paces of engine breaking in to finally back feeding my house panel to see it I can support a whole house operation. I will edit this review as I get more info. Amazon CS rocks. Update, I put the unit through a 5 hour break in. Replaced the break in oil with 5-30 full synthetic. Put in an NGK iridium spark plug. Then I powered the house and tried to start the 4 ton AC unit and it would not bring it up to speed. The generator overload kick out after about 10 seconds. I really wanted this to work, so with the bent frame issue I considered returning it because of this to get a bigger unit. Amazon said that if you put oil and fuel in it they could not take a return. Warranty through the company was an option. So I decided with the discount I received for the bent frame, I bought and installed a soft start for the AC compressor. The generator easily started and ran the AC unit on top of an already base load of about 2000 watts. I had it loaded to about 6800 watts and it ran flawlessly. I love the compact footprint. Fits under my workbench with a cover on it. I also decided to get a propane conversion kit. Runs on propane without a hitch, also to 6800 watts. All in all this unit is a great buy compared to other inverter units of the same size, and if you get a bent frame, if it's not too bad you can work the bend out with a pry bar and have extra cash from a discount for gas or a nice cover. The cover I got for this is very well made with great customer support.

The box arrived fine and appeared secure. I carefully opened the box and noted several sheets of foam packing were surrounding the generator. Assembly of the handle, support feet and wheels was straightforward. I noticed the left side wheel seemed crooked. Further inspection shows the axle bracket was welded crooked to the frame. Not a huge deal, but frustrating nonetheless. While adding oil, I noticed the plastic trim piece in the upper right corner of the control panel was broken in two places. Neither of these issues will alter how the generator performs but it sucks having something new out of the box that is already damaged. I went ahead with a test run and it performed fine. The engine cranked right up and ran without issue. It's loud, but this model was never marketed as a quiet generator. I hooked it up to my house using the L14-30 plug and it supported a 6000 watt load just fine. The crooked axle bracket is a QC issue for sure. Uncertain if the cracked plastic is QC or shipping damage. Time will tell if Amazon does anything to remedy this situation.
