Erayak 2000W Pure Sine Wave Inverter 12V DC to 110V 120V AC Converter for Home, RV, Truck, Off-Grid Solar Power Inverter with 18W USB-C, Fast Charger, LCD Monitor, 6m Remote Controller

This is a well made inverter. It is a high frequency inverter that uses only one large High frequency Toroidal transformer for stepping up the 12V dc to 170V dc for feeding the DC to AC inverter output stage, most high frequency inverter uses multiple small transformers instead.
Power consumption when inverter is on but no AC Load connected is only 0.4A x 13.6V = 5.44W which is very impressive for 2000W inverter, most are higher than 10W.
This unit can easily start and run my 1996 25 cu.ft Whirlpool without hesitation, I use this fridge for testing inverter surge capability, it has at least 3600W of power surge which most of the 2000W inverters that I have tested fail to start and run this fridge. 2000W AIMS and BougRV can run my fridge OK, but other brands have failed to do so.

Now the bad part:
The Voltmeter calibration is way off, it shows 115V ac on the display but my Fluke and Kill-A-Watt meter show 120V ac, this is will also cause the Watt display to be off also.
The cables that come with the unit are too small, you should use 2/0 wire gauge for this unit for the DC input wires. 2000W AC output/12V = 167A, 167A/0.85 = 196A on the DC input side due to 85% inverter efficiency.
According to the tech support, you cannot bond Neutral and Ground together otherwise it will damage the unit.
It only has 2 AC outlets.

We run this inverter while driving our SUV to charge Lithium ion batteries for our camper. It works flawlessly and I couldn't be happier with it. This inverter is somewhat big and very heavy but with the remote control, it's easy to start it. I can recommend it.

I absolutely love how well this inverter is constructed . I hooked this to a 12.8v 200ah Lifepo4 battery with 2 awg cables. I plugged in a 600 watt parabolic heater. The inverter functioned perfectly for this high load . No fan kicked on and the heater powered on nice and hot . I let it run for a good 20 minutes and no problem . The inverter never got hot with 600 watt continous load. I hooked up the remote power switch that was very nice. I could turn the inverter on and off when I was done using the heater . I am excited to use this inverter in my solar power system. I am going to use the inverter to power a mini fridge. I like how it can be shelved or mounted to a wall . The voltage on the lcd reading seems to be off by 2v but that is fine completely normal for most inverters . I am very happy with this inverter . Awesome professional product . Even came with some 4 Guage cables 4 of them total and ground wire kit .

The inverter functioned very well. I noticed a few things that keeps this from being best-in-class. The cables supplied are far to light gauge for something that has the potential of drawing 4kW. I tested the inverter using 2 AWG and I suggest anyone buying this to do the same, even for a short run.

I tested the output and it's definitely providing pure sine AC power. It was a little noisy, but not bad, at all. It would be nice if it provided 120V, it hover around 116VAC. It ran a 1600W heater without issues, as well as a hair drier that drew 1450W. The USB outlets work, and I even saw my S22 Ultra was charging at Super Fast, which is a definite plus. The LCD display isn't the brightest display, but it's acceptable. Just two AC outlets is a bit limiting for what is a fairly standard size unit.

This inverter is one of the best options for summer or winter emergency use. If you plan to use it continuously, you'll need the right capacitor. Double the 8awg capacitor to get 4awg, which is actually comparable to the inverter's output power. Don't count on the digital display, though. It's a rough estimate, but there's a 4-5V error depending on the input power. I powered it with a Lipo battery pack I built myself, and it got 15.43V.

It's currently selling for $249. Honestly, for a pure sine wave power source that can power a 500-watt refrigerator, a 1000-watt microwave, a 43-inch/75-inch TV, an internet modem, and prevent all my LED bulbs from humming or flickering for hours on end, it's a good deal (I connected it to my house during a lightning-struck utility pole that caused a power outage).

You can buy a ground fault circuit interrupter (GFCI) to plug into or connect to the inverter's output. It has a built-in fuse for protection, just like a car stereo amplifier. You can also add a 160A fuse to the positive battery terminal for extra protection.

Wanted a pure sine wave investor for my backup project and this fit the bill in all aspects that I wanted.

This is a really good inverter. It's spot on with the conversion and energy output and is so fined tune it works within specs perfectly. With 2000 watts, it can convert power for anything I need without issue. The pure sine wave attribute is critical to me. It prevents certain things from potentially being damaged or destroyed.

It has an 18 watt USB port which is great for fast-charge capable devices. I used it for several days camping not too long ago and it worked like a champ. I had no problems at all. The LCD screen provides current information and is nice a clear and easy to read.

It's a great inverter and I would recommend it.

Wow, this is one top quality inverter for my emergency backup system! I live in a hurricane impacted state and am using this unit with a solar panel, charge controller, and deep cycle battery as a way to provide power in case my electricity is out for a long period of time due to the lines at the road being down. In all the tests so far, it has performed beautifully and should be good for this purpose. I like that the unit has both 110 volt power outlets and USB outlets. I also like the status display on the top of the unit. In addition, the remote control is a nice feature although I will not need it. Only time will tell, but so far I am impressed with this product's performance. With that being said, I am ranking this unit at the top with five stars for sure!

I was able to hook this thing up to some of my industrial test equipment an analyze the output and the sine wave and it’s pretty spot on with what you’d be looking for in a pure sine wave inverter. I did further testing and it has run my microwave and my air conditioner without faulting out which only a sine wave inverter can do. The ground fault resets on the individual outlets are a really nice touch, as are the built in fast charging ports (tested to 20w). I like this inverter so much that I have decided that if it lasts another few months without fan or inverter failure, I’ll be adding a second one to my system.

Very happy with purchase, preaty heavy, sturdy aluminum body and quality made! I hope it last.
