Tips:Function of Pure Sine Wave UPS Inverter

  • Automatic voltage stabilizing function. When the battery voltage fluctuates between undervoltage and overvoltage, and the load changes within the rated power range, the device can automatically output voltage.
  • Overload protection function. If the AC output power exceeds the rated power, the device will automatically cut off the inverter output, the front panel LCD will display "Overload", and the buzzer will sound for 10 seconds. The "Inverter switch is off" on the front panel, and the "Overload" display disappears. If you need to restart, you must check that the load is within the allowable range, and then turn on the “inverter switch” to restore the inverter's output.
  • Overheating protection function. If the temperature of the control part inside the chassis is too high, the device automatically cuts off the output of the inverter. The LCD on the front panel displays "Overheating", and the buzzer sounds an alarm for 10 seconds. After the temperature returns to normal, the output of the inverter returns to normal.
  • Battery reverse protection function. If the polarity of the battery is reversed, the chassis of the fuse will fuse automatically, so as not to damage the battery and equipment. But reverse batteries are still forbidden!

High quality 600w ups inverter.
Love this 600-watt ups inverter. I power computers and various electronics in my van conversion. Once set up this 300W ups inverter works well. It's very practical.

Helped me a lot
I was scripting a firework show and the laptop battery died on me. I pulled this 600 watt pure sine wave ups inverter out and kept moving with the show. It did what I needed it to. Highly recommended!!!

Works well
Once setup it works well. I switches without a noticeable glitch when the AC power goes off. This appears to be a well made device that functions as advertised. I will buy again and recommend this ups inverter.
