1500 Watt Inverter Pure Sine Wave DC 12V to 110V AC Power Inverters with 2 AC Charger Outlets, Car Inverter Solar Power Inverters for Vehicles Home with LCD Display and 2.4A USB Charging Ports

The media could not be loaded. 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.

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 failureThis 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.

LCYMW 2000w 12vdc Inverter 9.23.24 Read Attached ThoroughlyInverter +/- Studs are 5/16” dia., the nut that secures the stud to inverter is Ferrous Steel (that’s bad). The open-end wrench provided is Useless because there are NO Hex Nuts for the +/- Studs on the inverter. Stud Nut caps can only be hand tightened and WILL NOT hold cable securely due to inadequate torque.35mm/2 (2 AWG) Cable provided has 3/8” ID Lug ends and not sized correctly with 5/16” inverter studs and does not have adequate contact between stud and cable lug.This is a SERIOUS Issue that can create Arcing, Fires, inverter failure and destroy all components connected. In addition, No spare Fuses were included as listed and No Information on Fuse Amps or How To Replace.The following items would need to be purchased In order to use this inverter: Qty. 2) @ AWG All Copper Cables with 5/16’ Lug ends ($30 to $40) • Qty. 2) 5/16” Stainless Steel Stud Nuts, lock washers & flat washers ($10) • Qty. 3?) Fuses Amps Unknown because No information listed and None were provided ($10?).Conclusion: At least $50 would need to be spent to purchase the items required to use this inverter which is already $190 + Tax. That make the LCYMW 2000w 12vdc Inverter the most expensive of it’s type on Amazon. There are more cost effective options. It is Truly Pathetic that Amazon & Sellers have declined so despicably in overall quality and are willing to have Zero Accountability for Integrity of products offered.
