Description

Remember when you had clean and quiet portable power? The WEN 4,000-Watt Inverter Generator provides clean energy, free of voltage spikes and drops for safe use with laptops, phones, and other sensitive electronics. Our 212cc 4-stroke OHV engine produces up to 4000 surge watts and 3500 rated watts of power. Designed to mirror a pure sine wave, this generator limits total harmonic distortion to under 0.3 percent at no load and under 1.2 percent at full load, making it safe to run sensitive electronics. Our ultra-efficient 1.85-gallon tank provides over 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, and one 120V RV-ready TT-30R receptacle. Maximize fuel economy 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, preventing the unnecessary usage of gasoline. Need more energy? Easily link up two generators using a WEN Parallel Connection Kit (sold separately) in order to share wattage amongst multiple units. Low-oil and low-fuel automatic shutdown combine with the built-in overload protection and indicator lights to safeguard both your generator and your electronics from damage. And because its 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.

  • A gem of a Inverter Generator
Style: 4000W Inverter
I was looking for a emergency home generator and looked high and low for one that used inverter technology. I was concerned as a neighbor bought a generator without a inverter and ruined a refrigerator and TV beyond repair. His generator was a 4000 watt unit at the same price point as the WEN. While I can’t speak for the construction the WEN appears better finished and more solid. Both weigh about the same. Both are open framed. The setup is like any new engine, read the manual. I did use Pennzoil Ultra 10/30 Synthetic oil, Premium gas with one ounce of Lucas Oil Treatment as I had good luck with the combo in my lawnmower, car and motorcycle. Absolutely no problems with set up and breaking in the WEN. There is a grounding wire tap on the control panel which I did attach to ground the generator as it was close to our main water inlet. Grounding the generator makes sense as electronics are extremely sensitive! An ounce of prevention now can save hundreds or thousands latter. My installation is in a home. I know nothing about use in RV’s or campers, but would think a ground makes sense there too. For me the WEN is an affordable and so far reliable Inverter generator! I think it’s a steal! Thinking of buying another so as not to stress out a single unit in long periods of use. Addendum: It’s been over a year and half now and the WEN is still doing its thing without problem. I installed an Hour Meter and accumulated 247 hours. I’ve changed the oil every 48 hours, installed a magnetic drain plug and a new spark plug if it look fouled. I still use Lucas Oil Treatment one ounce at each oil change. I bought a second WEN and now run them in parallel without any problems. The pair can run a 12,000btu a/c, full size refrigerator and a 1000 what microwave. I do turn the a/c to fan when using the microwave as not to stress the generators. No failures, starts with one or two pulls, very little smoke and have not noticed any change in noise levels. It’s easier to move two 60+ pound generators than one 8,000 watt unit. My volt meter shows a steady output. With load shows 6,700 watts steady and peak of 7,250 watts in parallel and 3,320 watts as a single unit steady state. ... show more

  • Easy setup and seems to be reliable
Style: 4000W Inverter
Easy setup, instructions were very clear and detailed. Generator is about 60-pounds, factory packaging was balanced and easy to move around. Open frame design makes it more convenient to move around, but I still had a friend or trustworthy foe on-call in case I needed it. Generator comes with 3 carb jets for different altitude ranges. The jet for sea-level to 3k ft is installed, 3k-6k and 6k-8k are in little zip-lock bags in the tools/parts bag. A small label is on the little zip-lock that says the altitude range for the jet, I'd recommend putting something in the zip-lock to show the altitude range. Instructions for changing the jets are included in the generator manual and in the little bags for the jets. Everything was included except fuel, oil, and the grounding equipment. Fuel is unleaded, 87 octane, holds about 2 gallons. Oil is .5L (a little over 2 cups or 1 pint). For grounding, I used a set of jumper cables and a piece of rebar for mobility. It started on the 2nd pull, ran smoothly. I didn't notice exhaust, although it was running outside on a windy day. It was louder than I expected, I couldn't have a normal conversation next to it. About the same noise as a gas lawnmower. Good generator, lots of available power. I'd get another if I need it. ... show more

  • Best value anywhere for inverter generator
Style: 4000W Inverter
Living in rural PG&E territory, unfortunately, so a generator is now a good thing to have in case of emergencies. I was looking quite awhile for a 4000-ish peak watt generator and stumbled across this incredible deal and purchased right away. One good tip for generator noobs: read the manual and follow the proper maintenance, startup and shutdown procedures. If you don't, you'll run into issues in the future. Once you know the tips, startup and shutdown is a cinch. One nice thing is it comes with a sparkplug socket, a wrench, a funnel, and high elevation carb kits. You can tell they took care in ensuring people use their products properly to get the most value out of them. I have not used this for an actual power outage, but I tested it on a couple things. I hooked up a chest freezer, a window AC unit, and our gas furnace all at once. Noticed no bog down whatsoever. It seems this will work great in a pinch. I would recommend you buy the RV adapter with a split that way you have more plugs to distribute the amps being pulled. They add up quickly. The weight of this is great. You can carry it by the frame for short distances or could put it on a hand truck no problem since it's pretty small. It is heavy enough where my wife would not be able to carry though and if it's hot you probably don't wanna move with for awhile. Cons: I don't think this is as quiet as advertised. With the Eco mode it becomes a little quieter, but with a lot of watts running it's nearly as loud as a traditional generator. I wish the fuel tank were a little larger as well to be able to get 10 hours out of it. I have seen reviews of people getting more than 7 hours though, so we'll see. A smaller tank does make it lighter though. Conclusion: no, this is not as nice as a Honda generator which would cost 4x what this one costs. If that's your expectation, buy a Honda. You know what you want. It does seem well built though, and if you take of it, it will take care of you. It's the best value for an inverter generator I have seen anywhere! Buy it, and if you hate it, empty your savings account on a Honda so you can brag to your buddies around the beer keg.🤣 ... show more
