2000 Watt Pure Sine Wave Inverter New in its box, unused. Device Specifications: 2000 Watt Pure Sine Wave, operates on 24 Volts. 60 Hertz. Built-in screen on the device to read battery and consumption + another screen you can install anywhere else. The device has been tested by colleagues before. Excellent quality and excellent performance. I bought it after seeing its performance with them, its light weight, and its suitable size. Of course, I made a mistake in the order and requested 24 Volts when I needed 12 Volts.
