4000 Watt Pure Sine Wave Inverter 12V DC to 120V AC, 4000W Power Inverter Surge 8000W Power Converter for Solar System, RV, Car, Truck (4000W 12V 120V

This inverter made it possible to use our cell phones, TV, and laptop without any problems to the electronics.

Stable, quiet.Single AC with 1 kW power works fine. If second AC (800 W) is hooked up system could not handle compressor inductive motor start. (Momentary consumption exceed 3.5 kW.0Two heaters 1.5 kW each work fine.Be aware that is disconnected inverter still hold high potential on DC input due to big capacitor.

Used this inverter for over 18 months , no problems. Worked great for small tools, saw, drill, refrigerator, lights. Then I need to air up a tire, small compressor blew it up. There is No reset or fuse to replace , no forgiveness for overload just smoke. I did I not realize it would completely destroy the inverter. Lesson learned.

I bought this inverter almost two months ago. I installed it and it's working 24/7 running a big refrigerator, water fountain and also brings power to tvs, pcs, lights, etc. It's powerfull, quiet, and very efficient. I'm planning to run lines to power a 30A tankless shower heater.A great buy!

This unit works very well without any lagging problems. The inverter ran everything l hooked up to it from a air compressor, air fryer, the whole TV entertainment system and portable a/c and a heat gun with no lagging.

Works great and have had no issues after a few months of constant use. I am 100% off grid and this powers my 5th wheel, AC, fans, and residential fridge. Will likely buy again when I go up to 48v but it does great at 12v.

Works great as long as batteries have power! Does everything it says it will do! Washer dryer coffee maker 55 incher TV. Not all at the same time! Happy with purchase!Not working right! Shirts of all the time! Batteries are full then when you turn it on it drops top 41 volts. Batteries won't charge because charge controller stops the batteries from over charge! So im heeing nothing from this inverter!

Original purchase: January 2020 - After six months: So far this inverter is doing very well. It does not get used very much, so it will take awhile to find out its longevity, but it appears very solid. I needed to have an on/off switch about six feet from its installation, so when I opened up the case to extend the switch wires from the switch installed in the case, I discovered that the electronic construction appeared very high quality, clean and well organized.October 28, 2022Update to my review after nearly two years: this inverter has provided satisfying power as needed most of the time. It will not power my RV microwave but it has not failed with other uses. I would not try to use it for my RV AC, since I already know it won't do the microwave. But I can't really be sure if it is the inverter or the batteries. There are nine 125ah gel batteries connected to this inverter and they are nearly always charged to 99% to 100%.Still, I am reducing my overall rating to 4 stars.
