4000W 24V Pure Sine Wave Power Inverter 24V DC to 110V AC with Wireless Remote Control LCD Display 1 USB Port, 4 AC Outlets, 1 Terminal Blocks for RV Truck Cabin Off Grid

This review is for the 4000 watt 24v version. The unit came well packaged with no issues in shipping, which was very prompt. Included is a wireless remote and extra fuses along with a usb cable to recharge the remote. The waveform is very sine as I checked it on my oscilloscope. Output voltage was 121 VAC. The inverter displayed 119 VAC which is within 2% tolerance, which is good. Output frequency was displayed on the inverter at 61 HZ. Actual was measured at 61.2 HZ. Which is quite acceptable. Very slight 37 KHZ noise present on waveform ~ 3 mv ac.Now to the business end of the Mxmoonfree inverter. I powered it from a Tesla 24VDC module rated at 4.5 Kw/Hr. Idle current was at 0.7 A. Connected a capacitor run inductive fan, pulling 500 watts, No Change to the waveform and output voltage raised 1 volt. In addition, I then connected a 7 in circular saw, Noticed no lag or waveform change voltage remained constant. Then to really test, with the fan and circular saw running, I decided to power a 12in Miter saw expecting to see something change. This inverter tackled it without flinching. I know I had to exceed 6KW for that 12 in saw to start, No change to waveform or voltage, even during this brutal surge. Output wattage was 3780 watts continuous. This beast handled it with no problem. I ran this way for ~3min. My battery voltage dropped slightly from the peak, and triggered the low battery alarm, but recovered almost instantly. However the alarm kept beeping until I turned the inverter off and back on.I ran a 6000 Btu AC unit from it for 24 hrs with no problem.Overall: This is one fantastic inverter that I feel very comfortable operating sensitive electronic devices from. The output is as it states as it will deliver what it is rated. The only cons I have are: Voltmeters are slightly off. I wish the low input battery voltage alarm would reset when the battery voltage goes back to normal. The remote had a way to extend the time before it times out.HIGHLY RECOMMEND THIS UNIT !!

This inverter is outstanding. One of my best investments.

The media could not be loaded.  MxMoonFree 4000 watt inverter is going back to Amazon. I will give another one a try before I switch to another brand. The Reliable Inverters 3000 watt that this unit replaced did not even come close to the Interference I now have and was able to remove the interference with clip-on Chokes which you will see in my video. The Clip-on Chokes vibrate and get hot and jump around and dont even come close to stopping the EMI and RFI. I have never seen a Clip-on Choke do what the Chokes do when connected to the MX MoonFree inverter. I did contact MXMoonFree tech support, they told me to add more chokes, I am at 6 on positive and 6 on Negative lines, which are 0 awg 1/2 inch cables. The noise that the clip-on chokes make comes through my HF HAM radio which is not connected to the solar battery bank, the radio is connected to 110 wall socket not the inverter. Added 2 pictures of my ICOM 7300 with the Inverter on and the inverter off. S2 sound floor off and S9+ with the inverter on. the inverter and the HAM radio are 70 feet apart on opposite sides of the house.

Mxmoonfree 4000W 24V Pure Sine Wave Power Inverter with fan works real quiet, even with simultaneous load from 65" TV, chest freezer, full size fridge, toaster oven and electric kettle, I would say about 3000W in all.Its been 2 months so far with no issue except the 60Hz output, to be precise, its 60.57Hz, rendered my clock useless in gaining 1 min every 2 hours. Other quirks is the fan, it was running at low speed with quiet chirp continuously at 100W load. It was like that for the first 2 weeks, then the quiet chirp went away there after.I am very happy with this model, I may consider the 5000W 48V version if I decide to upgrade next year.

The inverter was purchased and brought to Brazil, and naturally, the warranty seemed almost impractical to utilize due to the high shipping and tax expenses. Unfortunately, it malfunctioned within just one month of use in our RV. However, what initially appeared to be a regrettable waste of money ultimately transformed into an incredible tale of exceptional post-sales assistance.Upon reaching out to the manufacturer and explaining that returning the inverter to the United States was not feasible, they promptly provided me with comprehensive technical instructions and even sent the necessary replacement parts (I happen to be an electronic engineer). Thanks to their invaluable assistance, I was able to successfully repair the inverter, turning what could have been a disappointing experience into a triumph of customer support.

It works really good. It is also very nice to see the actual amount of power you are using, and bringing in!!
