Review on WZRELB Power Inverter 3000W: Pure Sine Wave 12V to 120V DC to AC Converter for Efficient Power Conversion by Steven Ali

I have tested it extensively and found it produces very pure sine wave power (using my digital oscilloscope). It works successfully at the maximum rated power, but gets hot, so be sure to leave some cooling air around the device. The cables that come with the device (which is a real plus as I didn't expect cables to come with it) are too flimsy for maximum performance. It is good that they are included so that the device can be used immediately, but people should understand that they should not be used at more than 50% capacity for any period of time. (My device is designed for 2500 watts of continuous power). I am currently using 2 gauge wire for my application which draws a maximum continuous power of 1800W. These cables are not cheap and I understand that there is no point in including such cables in every unit.
