Erayak Onduleur à onde sinusoïdale pure 2000 W 3000 W, convertisseur 12 V DC à 120 V AC – Idéal pour camping-car solaire, camping-car, maison, camion

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.
This unit can easily start and run my 1996 25 cu.ft Whirlpool without hesitation, I 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.

Needed to find a 3000 watt inverter because my 1500 watt pure sine wave inverter could not handle my 600 watt microwave in my Freightliner truck. The 1500 watt inverter worked perfectly fine in a Volvo so I thought it would work in the Freightliner. Well, I could not run the microwave for long in my Freightliner truck before the fuse breaker switch would pop. So I had to do my research. I found this 3000 watt pure sound wave inverter by Erayak. Purchased a new one and it came packaged with all the bells and whistles. Everything was in the box, the set up with a snap, and my microwave works as it should, and no popping the breaker fuse. Happy with this purchase and the extra power. The only criticism is that I do wish it were smaller. But fortunately it still fit in the spot where my smaller inverter was, but barely.

I have a few 2000 Watt Pure Sine wave inverters and this is the largest. I am not sure if that is because it has heavier duty components or is using older tech which is typically larger. But either way, this performs great. I live out in the country and my power goes off frequently. The pure sine wave is necessary for my computer UPS and systems. The external remote switch is very nice and the whole unit would be great addition in an RV. A 2000 watt inverter is not enough to run your house, but could run probably run an RV depending on what you have plugged in. You would need several for a house. Just double check the Wattage of the devices you are using. IMO, you never want to run an inverter at 100% load for very long and like to keep it around 80% load for any length of time. I will update if anything changes good or bad.

I ordered this for an off-grid pavilion with solar panels and a battery bank. It has a nice remote 'on/off' switch and the wiring to control it. The packaging is good. I haven't hooks up an oscilloscope but everything seems to work like it was on line power.

This would be great for a small home with minimal power requirements. This will require a pretty good sized battery if you want to use it with stuff like a microwave (small) or a hair dryer (1500W) I am pretty impressed with this.
