LCYMW 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.

This is for the 48v, 5000W inverter. Update 12/27/24 - after using this for a while I still like this inverter, BUT- it's a power suck. When this is on it will CONSTANTLY pull about .82-.86A from the battery 24/7. I have a fridge plugged into this, so I can't just turn off the inverter, because.. fridge. Things have to stay cold/frozen. But when the fridge is running there's a 1.75-1.85A draw. When the fridge isn't running there's a .83-.86A draw. That adds up to a lot of lost power that does nothing except drain the battery. I'm hoping the seller will see this and get back to me with a solution. I sent 2 other inverters back because they didn't perform as claimed. I set this up for testing and it did great, just as a reliable unit should. This is a big, beefy inverter, a little under 21" long. I have a small professional woodworking shop, so I used tools for the tests. So, the bench test.. I set this up using a 48v 100Ah battery from my power station to provide power for the test. I plugged in a small heater (~1200W), a larger heater (~1600W), an orbital sander with the vacuum connected to it, and an air compressor (1.8HP vertical floor standing unit). I turned on all of these, one at a time to watch the progress on both my battery monitor and the readout on the inverter. With all of these running the inverter reported 4916W. This number went up and down a little, but there ya go.. I also found out that when using the remote I can change the output on this from 110/115V to 120/125V. Apparently this is only possible with the remote, which is connected to the inverter with a cable (provided). When I changed the output voltage to 120/125V I ran the same test, this time the readout was showing 5554W, which is 10% above the rated output. It kept doing this for about 10 seconds before it shut down.. I think that's pretty good, going that far above the rated output for that long. The other inverters I tried was the 2000W KRXNY, which kept shutting down at about 1750-1800W. The other was a 3000W aeliussine, which kept shutting down in the 2750-2800W range. Hope this was helpful.

I’m very happy with my purchase of 2000w power inverter. Needed it for small solar power project for my camper. Watched hundreds of videos of people who understood inverters and explained this model in detail and opened it up to show quality made and heavy duty. Most claimed it was large and heavy for 2000w model I found, but space wasn’t an issue for me. It was mainly price point for a pure and not modified wave unit. I learned to switch it to 120 from another review to hold down button on remote, it will then switch to zero and throw a code, then switch off unit and turn back on and it will switch to 120. Vice versa to change back to 110. I’m very satisfied as it powers my 700w microwave and coffee maker as I need for my camper. Thank you for what seems to be a good product at a good price. Longevity will be my next come back review in a few months! Mike 12/11/24 update I have since purchased the 24v 3000watt model. I changed my 12v system to a 24v system and was so happy with the 12v inverter I decided to give there 24v 3000watt model a shot and am definitely happy with it. Especially price influenced my purchase, however I had a question for the manufacturer which I posted on 12/1 through amazon and still haven’t received a response. I see others have gotten responses from them, however it’s now the 11th and still nothing even after resending my question again on the 6th. I’ll give them another week and will update. 6/10/25 Update Been running this inverter off 2 12-200amph batteries in series for 24v. Been running microwave approx 1450 watts, A/C unit at 790 watts with compressor and around 300 without. The inverter has also run both(by accident, didn’t mean to push it) but at same time with no problem. Fan comes on around 45*c for about 45 seconds every once in a while when running A/C continuously. Runs coffee maker as well at around 12-1400 watts. My original 2000 watt model also still works fantastic. I use it on a smaller 12v system to power my portable fridge freezer and some power tools out of the back if ny van as I need them on the road. I didn’t know who this company was when I got started a couple years ago but have bought a 12v 2000 watt model and a 24v 3000watt model and they have both served me well and still do. I would definitely recommend and order from them again. Life is good and both inverters have worked flawlessly !

Let me be perfectly clear. This 48v 5000w inverter EXCEEDS my expectations and I recommend it. I did not expect it to be this good in view of the price and the fact that it is a high frequency inverter. It has surprised me and surpassed my expectations. It runs 24 hours a day, 7 days a week without so much as a hint of failure or issue since I purchased it. Background and more detail: I have a WZ... 3000w inverter that cannot do 2000w of air conditioning without blowing fuses. I increased the inverter cooling and replaced the fuses with breakers. It stabilized the WZ... inverter at 2000w but then the 30a panel started melting at less than 25a. That first inverter was a failure This LCYMW Inverter does well over my typical 3000w load and can likely do much more. Air Conditioners are hard on inverters but this one doesn't flinch. I am impressed that it puts out 123v with a light load and 121v with over 3000w The standard specification for standard house AC outlets is 110v to 125v but rarely do you find an inverter that goes over 120v. The single fan all aluminum case design does VERY well at keeping the inverter cool. I would prefer a low frequency inverter with large or massive coils. I am amazed at how well this high frequency inverter works. MOST power supplies (inverters are a type of power supply) will burn out at a constant use above 80% of rated capacity. I would not expect this inverter to be reliable above 4000w though I have no proof that it would not be. That would just be another "exceeds expectations" if it is stable past 4000w. I did perform one test where it ran for over 3500w for 5 minutes and it worked perfectly. For the price, this is hard to beat. The only downside that I found was with disassembly. It is exceedingly hard to get the two sides of the "clamshell" case to line up correctly. The next time I take it apart, I will replace the screws with studs or grub screws so the aluminum heatsink case halves will line up with the front and back plates with less effort. I consider this a minor issue that only matters if you overtax it and blow a fuse. I only opened it up to examine the construction of the unit and verify the fuse locations. Cooling fans are a big concern on inverters. I specifically bought this inverter because it came with a heavy duty 120mm x 38mm fan. I will never buy another inverter that comes with 60mm fans. They just aren't big enough to cool a serious inverter. I bought this as a stop-gap inverter until I can purchase a 10,000w or 15,000w high-end low frequency inverter. Now i want to keep using it to see how long it lasts.

We decided to buy the 5000w 24v because we have been using their 2000w 12v for several years now and have been very satisfied. Set it up and was very excited. There was a low quiet but noticeable click almost like water drips, drops that seemed to disappear once there was a load on the inverter. Everything seemed fine and I loaded it with the coffee maker and the house electrics. I never got the fan to kick on and got busy with something else and noticed that the inverter had just stopped after only two hours of turning it on. No beeps nothing. Screen was dead. The remote still displayed and showed no current but did show error codes E05, E06 and E08 which the manual didn't give enough information for me to troubleshoot. I immediately emailed the support email. I took it apart and tested all the fuses, all tested ok. The company has yet to respond. So I've started a return with Amazon. It's a shame, I was looking forward to this upgrade.

Works efficiently....easily install...noiseless It was reasonable priced low consumption
