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

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.

The media could not be loaded. 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.
