I bought two 3000w inverters with my own money. Admittedly, I destroyed them both due to storing them inside an enclosed space - perhaps even some other factors I created as well. The inverter(s) worked well and came highly recommended by YouTube sensations John "The Headsamsher" Daniels and his daughter, Keira. Their wild video put this product through rigorous paces and it passed all tests of what was thrown at it. their video was convincing enough; proof enough, to buy the Erayak inverter - twice. After blowing the internal capacitors (28 total between two inverters), I decided to reach out to the company for advice on where to find the correct capacitors for a replacement. Erayak's customer service team were sympathetic to my plight - so much so, they recommended that i toss the purchased two units and at their own business expense, send me a new one the next day. They even paid for the shipping and handling costs. I paid NOTHING! I am here now to pay my well-warranted gratitude. Erayak showed more concern for me and my safety above their bottom line. I now have the new unit and am having it installed inside a better, well-ventilated location in my RV. Thank you Erayak, for you never even publicized that, why, or how, you helped me. You just quietly did a good deed. John "The Headsmasher" Daniels, if you're reading this five-star review, you were right about this company. they do care. they do listen when their customer speaks! Buy quality products made by Erayak. You'll be glad you did.
I am proud to say that I purchased the DSU-3000 Pure Sine Wave inverter based on the highest recommendation by John "The Headsmasher" Daniels and daughter, Keira. That YouTube electronics sensation duo really put this model through its paces, and the equipment never failed to amaze them, or fail in any respect for that matter. John also said that Erayak is a company that listens to their customers when a good suggestion is made. I personally now know how true John words are. I foolishly destroyed not one, but two of these inverters, by not knowing how to best wire them. I blew up two sets of internal capacitors - perhaps due to having the inverter inside a space that was not ventilated well enough. In any case, I wrote to the company, explained my failure and honestly owned up to my misuse of their product. they not only commended me for telling the truth, patiently giving me electronics advice, then offering to send me a replacement unit at their expense - including shipping! Who does that in this economy?! Not only are the products top-notch, but so is their customer support team. My negligence destroyed two masterpieces! Yet, above their merchandise and reputation, Erayak showed concern for my dream and most importantly, my life! Then they went and sent me a replacement to show support. Thank you, Erayak! I will be forever grateful to you.
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.
