First I want to start off with product support. Email is your only option, however Bonnie is very prompt and gets right back to you. Just keep in mind there's a time zone difference between the US and China, so don't expect answers during non business hours in China. Bonnie answered all my questions right away. I have just installed this unit in my 5th wheel and only tried it with my microwave, coffee maker and power seats. It has sufficient power to run my microwave and the Kerug at the same time if that happens to occur, along with TV running. We really only want it for short overnights such as Harvest Host stays where we don't have shore power. Not using it for A/C. Some things to note. As a previous reviewer stated, the power terminals for hardwiring the output are very small and would not really accommodate 10 gauge wire. Since I was installing on a 30 amp converter pre-wired circuit I ran the 10 gauge from the RV to a transfer switch and out to a box then tied in two of the inverter 15 amp outlets to the 10 gauge and used two of the inverter outlets verses the screw posts. As it is, this provided another advantage. When I powered up the inverter I found the ground was not bonded to neutral. I sent a message to Bonnie as to whether I could bond the ground to neutral without damaging the inverter and the response was yes you can, will not damage the inverter and others have done the same. So I used the Neutral and Gnd screws on the unit to bond the two together and it works fine with no more open ground. I also found the cables provided with it very small gauge for a 3000 watt inverter, so added my own (4/0). The remote display is great. Provides the feedback I want (voltage output, power consumption and a battery voltage indicator). And it lets you turn the inverter on and off remotely which is a plus. The 14' phone cord that came with the remote was too short for me so I purchased a 25' line cord from Lowes and had to cut off one end and re-terminate on a new RJ11 plug as the inverter cable has a straight through RJ11, where-as the line cord from Lowes had one end flipped. Easy fix and the 25' cord works fine. Time will tell on reliability, but for the cost so far I’m happy it. Will be testing out over the next 8 weeks on an RV journey.

I bought this to upgrade my Thor sequence 2022 van they only had a 1,000 watt inverter in it so I did a conversion from AGM batteries 200 amp total to lithium 600 amp total so I can run my AC and my microwave without starting the generator every time. This inverter seems to work really good I've only ran it for a week but it's been working perfect. When you hit the higher amperage levels or higher Watts you'll hear the fans kick on. So I wouldn't mount it inside a closed cabinet if you want to have a really good Cooling effect. I put it right next to it /behind the driver's seat where it's hidden very pleased with that choice too. It has four outlets on the front but I used the hard wire AC to link it into a transfer switch. I bought an extra transfer switch and put it in series after the first transfer switch so I can do Shore then Jen then inverter as the logic order to provide Power for the higher amperage panel that does the air conditioner and the microwave. Then the only thing I had to do to make the logic work was between the two transfer switches I put an AC breaker coming off of that line and made an isolated circuit to the RV battery charger converter. That way I'm never using the inverter to go in a circle to charge the batteries which go to the inverter again would make no sense. So this inverter was the cherry on top of the whole project pretty happy with the outcome.

I have run two large shop fans, 500 watts of lights, and power tool chargers all at the same time and the cooling fans never came on. So far so good, no complaints here.

The unit worked very good for me. The standby power usage was very low, which is what I wanted. The cooling fan, which would use a lot of power, was temperature controlled, so, it would stay off when under low load. This makes it operate more efficiently. I have 2 cons about this unit. 1) the terminals are way too small for the amount of load it can provide. 4000w at 120v is 33 amps. NEC requires #10 copper wire for this type of load. There is no way to connect #10 wire to the terminals. The screws are so tiny, you could never get any type of connector to work. I had to purchase 4 plugs, and wire them to the #10 wire with a terminal block, in order to safely provide power to the distribution panel. 2) the remote box is not flush mount. I think it would be easy to modify, but I have not gotten there yet. Otherwise, the box it comes with is fat and clunky.

I have purchased this unit and it has been working for me ever since it’s the best unit I’ve ever purchased. It’s the best inverter ever. I love it. I will recommend it to everyone friends and families. Please get this unit for your work for anything that you need to do power wise it says what it does and it does what it says

I actually have 2 of these. I liked the first one so much I bought another. This unit has been powering my small travel trailor for almost a year now with no problems at all. I mounted it up high to discourage bugs from getting in it, and its in the open to keep it cool. Since I rely on this inverter to power my little house and I'm completely electric, this is basically my power grid and it runs 24/7 every day. Make sure you feed it with 2-0 wire or equivelent to keep the connections cool during high demand and you'll have a long happy life with this unit. It will run my roof AC unit but I use a 8000 btu window unit now as it only needs 500 watts whereas the roof unit is 1500 watts for only a little more air. I cook and run the refrigerator too and it starts the refrigerator and the AC unit without any overload problems. I have overloaded it one time when the toaster, Roof AC, and MIcrowave all came on which is over 3000 watts load. It should down, beeped, and came back on by itself with no damage but I don't want to push my luck. I would recommend this model to anyone who needs reliable AC power full time or part time in emergencies or camping. Just keep it dry and cool and you'll be a happy camper like me :)

UPDATE March 19, 2025: Almost 2 years now! LOVING this inverter! TIP: Make sure it's mounted flat, not sideways, it's in the instructions. I use typically a max of 1800W. Runs cool and quiet. I had a question and called Egscatee, Egscellent customer service! I Highly recommend this product! The highest power unit I run is a Ninja double air fryer oven. I do not use both top and bottom at once. However, the upper oven can do everything, and I use as an oven, and can use on broil-low setting which is 1800W. However, my circuits couldn't handle much more, greater than 1800W my outlet strip circuit breaker trips. Love the Ninja also. I can toast, cook a chicken for 45 minutes, etc. Also can use espresso maker 800W, boil water 1000W, an electric frying pan, The inverter handles it all! 5 months now, I'm having no issues. To be fair, I'm running well under the rated power. Maybe 1800W max.and I don't plan to run at 4000W. I'll keep you informed. If it runs longer than say 4 years, I'll be happy, but hopefully will never fail. It defeats the purpose of the savings from running my solar cells. In picture mounted wrong, should be mounted horizontal. I only load this half load max (2000W) most of the time. My inverter is 4000W. So my outlet strip trips first. You must mount properly horizontal according to instructions. My previous different manufacturer inverter only 2200W was mounted sideways and went bad. Opened up and found fuses tilted down and melted fused together. I'm sure mounting makes a difference. Old inverter read 110 Vac, this inverter reads 120Vac, much better. Hopefully will last a long time.

While it did work fine for a few months. Then it went out with an overload claim. Since none of the 20 AMP fuses in the cabin panel box blew, an overload was impossible. I replaced it with another inverter and took it apart to see if it had a blown fuse since it came with replacement fuses. I got the case apart only to find that the internal fuses were soldered in place instead of socketed. This made it impossible to repair.
