LVYUAN 1000 Watt Pure Sine Wave Inverter 12V to 110V 120V DC to AC with U.S. Outlet, USB Charger Ports, Car Power Inverter for Vehicles, RV, Outdoor, Home

Nov. 30, 2019. Dont like the fact that there is still power draw when the unit is off, just have to install a 12v 50 amp breaker switch to cut all power off to the unit. But it is 1000 watt power that and a pure sine wave is a plus. This is for a backup power off grid setup and for my RC hobby trailer. Dec. 12, 2019. An update. I have bought electric blankets to use on inverter but the one I had kept burning the blanket out. I got this 1000watt inverter with sine wave technology and used a new electric blanket on it. Worked flawlessly. So...to sum it up, I'm happy with it.

Works great! I have this powering my 1 terabyte DVR and 4 cameras in my enclosed trailer. I have had it for a couple weeks now and it stays on all day. It gets warm but not hot. Monitor has a better picture quality than the cheaper one I had.

I got this today. But when I took it out of the box, I immediately noticed something was rattling around inside it. Sounded like a screw or something, falling from one end of the case to the other. I put it back in the box, submitted a return request, and ordered another. On the plus side, this thing is really compact. That was a big factor in my purchase, because it's destined for a fairly small place under the hood of my Ram truck. I use an inverter to provide AC to both my camper and my trailered boat, keeping the batteries in both charged and running the camper's fridge on AC instead of LP. I've been using a 750W Powerdrive for years, but wanted to upgrade to 1000W and pure sine wave. This unit is one of very few I was able to find that's small enough to work for me. I'll update the review after I get the new one and put it into service. Edit 6/25/22: Got the new one. It doesn't rattle. I installed in on my truck and tested it and all is well, it works perfect. The loads are happy to have a true sine wave, the modified sine wave from my previous inverter caused some buzzing from certain devices and those devices are now quiet. Upgrading to four stars. Will update if anything changes.

This is an excellent company to do business with. Even though my inverter was over a year old they worked with me to get the correct one. The one I had purchased wasn’t a pure sine wave and wouldn’t run my CPAP machine. Rin worked with me over several days and emails to determine that I needed a pure sine wave to run a medical device and even offered a discount on a new one.

I'm trying to capacity test 2 new LifePo4 batteries and was trying to use a small space heater to provide a constant draw. I plugged a Watt Meter into this inverter and then plugged the heater into the meter so I could adjust the thermostat accordingly for the draw needed, and account for the 85% efficiency loss as well. Unfortunately, even keeping the heater set so as not to draw more than 800W (~750W on meter while bluetooth battery stats showed ~60A @ 13.2V = 792W, [closer to 95% inverter efficiency]), the inverter cuts off intermittently until it cools enough to cycle back on; lather, rinse, repeat. Yes, the internal cooling fan IS turning on and running like the dickens until the moment the inverter quits/shuts down. The inverter casing (heat sink) and alligator clip cables became too hot to touch after about 10 minutes total use. Because it does have some utility at a lower wattage draw (I'll trust it to maybe 500W) AND seems to truly be pure sine wave, I'll give a rating of 2 stars. However, if you must have continuous 1000W operability, buy something else.

Yeah I highly recommend this You're not going to go wrong especially for the price.

The power output is clean and fits my needs. I have it connected in a 12v lead-acid system with 195W solar panel. I will test further, but the unit (in garage out of sun) gets warm even with nothing plugged in, let alone drawing a load. Specifications state an idle draw of less than 0.8 amps...but the noticeable warmth seems suspicious for that to be true. It is warm as if under a light load. Like I said, I will test further and update. Update, February 2021, after our Texas winter storm emergency. Unit failed under bigger load. It's rated for 1000w continuous but failed after 15 minutes running a 700w space heater. Unit started smoking and smelled horrific. Failure during a natural disaster is horrible. You get what you pay for. Shame on me.

It powered my 1500 watt induction cooktop! Also my toaster (750 watts) and coffee maker (850 watts) The fan only comes on under a heavy load and is very quiet. I would definitely buy it! Carl

good sine wave output

Work well! My pump needed 500W and this converter does the job without problem. I use it to pump my big inflatable boat. It's a bit expensive though.
