Pure Sine Wave Inverter Remote Control & LCD Display (Optional)

  • Pure sine wave power inverter is available with remote control: wired control and wireless control.
  • LCD display shows input voltage, output voltage, output frequncy, battery capacity and power.

Pure sine wave power inverter remote control


  • Intelligent integrated circuit control
    Unique front and rear dual soft start technology, CPU core, SPWM pulse width control technology, special constant power technology, anti-reverse diode technology.
  • Pure sine wave
    100% pure sine wave output, low distortion, waveform and main power line AC waveform are basically the same, equipment accuracy is small, low interference, low noise, strong load capacity, can meet any type of AC load, without damaging the load.
  • Imported parts
    The materials are imported components, and the panel uses double-sided circuit boards to ensure high quality and high performance of the products, and to match the excellent quality of the detailed molds.
  • Aluminum alloy casing
    The surface of the aluminum alloy shell is sprayed and anodized, which is small in size, elegant in appearance and easy to carry.
  • Working instructions intuitive working state
    When the inverter undervoltage/overvoltage, overload, overtemperature, short circuit, the LED indicator lights.
  • Multiple protection functions
  • Fault warning/buzzer alarm reminder
    When the inverter high voltage, low voltage, over temperature, overload protection function is turned on, once the protection of the inverter is triggered, the inverter disconnects the power supply and the load enters the protection mode for the first time, and issues an alarm through the buzzer alarm device. Make your use more secure.

Pure sine power inverter applications

Tips: How to Distinguish Inverter is a Pure Sine Wave or Square Wave?
• Detect the waveform with an oscilloscope
• Carry a power frequency transformer separately and attach it to the ear to listen to it. The noise is square wave.
• Plug in the electric fan to listen to the motor when rotating, square wave, correction wave, motor ultrasonic is very large, pure sine wave inverter will have no ultrasound, just like the mains operation.

I have been using a 48V inverter till now
It's been over half a year since I installed this inverter and still no problem. The pure sine wave inverter is a great power supply unit to run 2 ovens, computers, microwaves, etc.

Very happy with this inverter
I’m very happy with this pure sine wave inverter. I had tried many other inverters without good results. And so far I am pleased to have chosen this one. I will buy again and recommend this product.
