Power inverter sockets


  • 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: I Want to Buy an Inverter for My Refrigerator, What's The Best Inverter to Buy?
Refrigerator is motor load, can not use ordinary square wave inverter and modified sinusoidal wave inverter, start difficult and easy to damage the inverter and refrigerator, can only use pure sinusoidal wave inverter. The refrigerator is about 200W, the starting current will be very large, with more than 500 watt pure sine wave inverter.

Fast shipping and very quiet.
Fast shipping and works well for my needs. Very nice oscilloscope AC sine wave pattern with almost no distortion. This inverter is silent, and I would definitely recommend.

Great customer service
I ordered a 48V pure sine wave inverter. When I tested it, I found that it was not working properly. I contacted and they soon sent me a new 48V pure sine wave inverter. Excellent customer service.
