2000 Watt Inverter Pure Sine Wave DC 12V to 110V AC Power Inverters with 3 AC Charger Outlets, Car Inverter Solar Power Inverters for Vehicles Home with LCD Display and 2.4A USB Charging Ports

I bought this inverter last December so it is about one year now. The first one I received works but somehow the idle power consumption was increasing after the initial power up. The display showed there is about 36W power consumption initially then went up all the way to more than 200W in 2 hours or so, even when I am not using the inverter to power anything. I contacted the seller then they responded quickly and worked with me closely to understand the issue. Somehow they cannot replace the unit directly and guided me to go through Amazon return process. I bought this with discount so it was little challenge but luckily I got another chance to purchase it with similar price so I returned the defective unit to Amazon. The replaced unit works perfectly in last one year now. Its idle time power consumption is excellent and probably one of the best in the market. I am using 600W solar panels with Victron 150/35 solar charge controller (SCC) along with some LFP batteries as my off grid solution. This inverter served me very well and overall efficiency is about 86% for the inverter while the solar to battery charging efficiency is about 96%. This gives me about 82.56% based on my Victron input solar power vs the inverter output power measured by Emporia smart plug in last 12 months. I am very happy for the result. The inverter pure sine wave is quite good as I measured in the attached picture. There was some complaints online that the output may not be perfect as the waveform will jump around on the scope. This might be related to the zero volt switching control issue on this design when the trigger level is set as zero voltage by default in the oscilloscope. When I adjusted my handheld scope trigger level to higher level then the waveform will not jump around anymore. I am normally using it for my off grid appliances such as hot water boiler, coffee grinder and drip coffee maker, as well as watching TV and listening music, etc. with about 450~800W peak usage. The inverter is very quiet in winter time if the power consumption is less than 1000W. Exceeding 1200W such as I am using water boiler while watching TV then it will trigger the fan continuously which is little noisy but not too bad. In summer time when the ambient temperature is 80F or higher then even using about 600~800W the fan will kick in like every 20min or so but it is very short period of time. Overall, I like this inverter especially with its good efficiency so it does not drain my battery overnight at all. I can keep my small refrigerator along with some other standby power usage with it 24/7 no problem for my batteries. I highly recommend this inverter if you are looking for low idle power one.

Recently bought a 1 kw litime inverter to go with my LiTime batteries. Sorry to say, their batteries are pretty good but their inverter is garbage. Returned that 1 lb paperweight and got this guy. (Included a video of my test setup btw) electric display info is pretty accurate, conversion efficiency rating is pretty spot on, right around 90%, cooling system seems to work very well. Ran at 800 Watts for around 7 minutes and never even heard the fans. Temperature held around 31C. The remote panel seems to work pretty well. FYI there is a 110/120 button on the panel. Press it and hold it down and the machine will throw an error code. Simply turn the machine off and then back on again and this will set it to 120 volt output instead of the factory 110 setting..... (Which is awesome btw)This is nowhere in the "instruction manual." (The manual is written in HongKongphooey English btw) video isn't narrated, but it shows one of my only two complaints. The wattage display does not work properly until it gets over about 40 watts. Other than that all the readings are pretty accurate. The soft start technology works flawlessly. It runs my high amperage tool just fine but brings on a space heater nice and slow. Also, not shown in video, I verified the temperatures with a thermal imaging camera. Only other real complaint is that the plugs are very loose. Is this normal or did I get a refurbished/returned product? I don't know.... I do know that it does seem to work great. Oh yeah, the power lugs on the back are kind of crummy too. But not that big a deal. Main concern is the loose plugs.

I purchased the 24v 3000w inverter in April of 2024 and used it sporadically at an off grid cabin. Worked great for about five weekend and then began erroring on startup with an over temp icon. Outside air temp was in the 40s and it ramped up without fans turning on. Likely the temperature probe or control board failed. No response to multiple messages to the seller. I now have a useless inverter and no money to show for it. Would highly recommend purchasing from a different seller/manufacturer. These guys are a joke.

SUMMARY: - Good price for the quality. - Positive reports of customer satisfaction as compared with many other inverters — and I did a LOT of research. - I’m happy with its performance in my solar system. - Excellent customer support. - I think it has at least a one-year warranty, but, if that concerns you, you should contact the seller in advance to check. - You can switch between 110v and 120v output voltage. In recent years, I’ve come to the frustrating conclusion that — no matter how much money you’re willing to spend on a product — sometimes you simply can’t find something of decent quality. This was most definitely the case with my search for an inverter for our solar system. On many occasions, over the course of several months, I spent hours at a time scouring the internet for that elusive inverter that would have overwhelmingly consistent and positive reviews. I was looking for something in a “reasonable” price range, but — out of curiosity — I extended my search to some of the top brands. I found that even some of those highly reputable brands have begun selling sub-par products in recent years. So, the only thing that really keeps some of those businesses afloat is their “name.” At some point during my months of searching, I stumbled across LCYMW inverters. I gave them serious consideration because the ratio of “positive” reviews to “negative” reviews was … well … positive. There weren’t many reviews to read at the time of purchase, so I was a little bit leery to make a decision based on only a handful of legitimate reviews. (Being a steady Amazon shopper, I’ve gotten pretty good at discerning valid reviews.) After deliberating for another month or two, I finally made a decision to purchase the 3,000-watt, 12-volt model. This model comes with a remote device which includes a button to switch between 110v and 120v. For me, this was an important feature, but, for you, it might not be. I’ve now been using this inverter for a month or two. I use it to power my tiny home, using a 600 amp-hour. 12-volt bank of LiFePO4 batteries. (Of course, being that it’s only a 3,000-watt inverter, I have to be wise about how many appliances I use at once.) Does the fan abruptly turn on sometimes? Yes, but it’s far less alarming than our dehumidifier and air conditioner, so I don’t see this as a big deal. Is it large? Well, yes. It’s pretty hefty, but it’s a power inverter. What do you expect? It’s a giant, aluminum heatsink with a lot of open space inside for air circulation. This provides lots of heat dissipation. That’s a good thing. Does it parasitically consume power from my battery bank? Honestly, I cannot attest to that with specificity. Of course, it uses power because it’s filled with electronic components that are doing their jobs. Still, I have no reason to believe that it’s using a ridiculous amount of energy. If you get one that does this, exchange it. You probably got a lemon, have incorrect expectations for an inverter in this price range, or else your testing methods are incorrect. Going back to what I said at the beginning: it’s difficult even to pay a lot of money for quality inverters these days. So, whatever inverter you decide to purchase, you ought to have the ability to test it within the return / exchange period anyway. Don’t assume that, just because you’re buying a “big name” brand, it’ll work properly (or last for a long time). For me, in the end, the choice was simple. The LCYMW inverter had the highest proportion of legitimate, positive user reviews, and the price is so fair that — even if it only lasts for a few years — it’s a better value than purchasing an $800-$3,000 inverter that might only last for five to seven years. Adding to my positive recommendation: I reached out to the seller with some questions and found out that they are directly connected with the manufacturer of these inverters. They were extremely helpful and provided clear, professional responses to my questions. Of course, I was cordial with them. If you jump on them with a bunch of accusations and frustrations, I can’t make any promises as to how — or if — they’ll respond … but I’m guessing they’ll do their best to be kind. A lot of well known inverter manufacturers have warranties and "free support,” but I frequently read reviews written by people who reached out for support from some of these companies and received shoddy support or no response at all. That’s not “support..” As of now, I’m completely satisfied with my purchase, the support, the seller, and the manufacturer itself.

Bought this several months ago, and it has worked flawlessly. Handles high loads like a champ and is quiet. The remote screen flickers more than I would like but it is still a nice feature. Time will tell how it holds out

This inverter is solid and reliable, works very well. The price is reasonable. The power is pure sine wave, can provide power to all kinds of electronics, appliances, and sensitive equipment's with motors. The display is very nice and shows all the performance measurements. I highly recommend this inverter. Just to update this 3000w Inverter, I have been using it for the past 6 months, it works very well, I use it for move the Genie Lift up & down, required 2000w of power, no issue, extremly happy with the performance, don't need to carry a generator anymore, no more disturbaning noise, and use this inverter for back up power at home as well during power outage.

Bought this a couple of years ago but never really used it until last winter and it worked great. The other day I powered it up and there was nothing on the screen and no fans. I'm really disappointed that Will Prowse recommended this inverter because basically I now have a boat anchor. No way to contact customer support. Listen to other's suggestions and purchase something else!

At first glance, the LCYMW 3000 Watt inverter is of a surprising size and weight, but this product is perfect for its use in my RV. Drawing its energy from 2 deep cycle batteries, it has no problems supplying power to my TV, DVD player, a small fridge, even my electric drill. With the display, I am sure not to exceed its capabilities. The manual shows its installation on a floor, but after checking with the seller, the inverter is suitable for wall mounting, bolted horizontally for safety and stability. I completed the installation of the inverter without any problems and even though I had to use longer cables (36in - Gage 4), it is functioning perfectly.
