    Protection Functions & Applications

    pure sine wave power inverter protections

    Pure sine wave power inverter applications

    • Reverse Polarity Protection
      Auto protection when input positive and negative polarities are reversely connected – The fuse blown out.
    • Short Circuit Protection
      Automatically self-protect when short circuit occurs – Red LED light ON.
    • Low Voltage Protection
      Automatically protect when in low voltage – Alarm first, the voltage continuously reduces, the red light is on and the inverter shuts down.
    • Over Voltage Protection
      Automatically protect when in high voltage – Red LED light is on, and the inverter automatically shuts down.
    • Over Temperature Protection
      Automatically self-protect when at high temperature – Alarm first, the temperature continuously rises, the red light is on and the inverter shuts down.
    • Overload Protection
      Automatic self-protection when there is overload – Red LED light is on and the inverter automatically shuts down.

    Tips: What is the continuous output power of inverters? What is the peak output power?

    Some electric appliances or tools within electric motors, such as refrigerators, washing machines, electric drills and so on, require a large amount of current to drive at the moment of startup. Once started successful, they need only a small current to maintain their normal operation. Therefore, for the power inverter, there is continuous output power and peak output power.

    The continuous output power is the rated output power. Generally the peak output power is 2 times the rated output power. For example, the 4000W power inverter has the continuous output power of 4000 watt while its peak power is 8000 watt. It must be underlined that some appliances, such as air conditioners, refrigerators, etc., have a starting current equivalent to 3-7 times the normal operating current. Therefore, only the inverter that can meet the peak power of the electrical appliance can work normally.

    In this video, ATO makes a simple test on the input and output voltage of 1000W 24 DC to 220V AC pure sine wave power inverter. And, this power inverter is used to power a cell phone and a fan which work normally.

    Love this pure sine wave inverter
    Installation was easy with heavy gauge DC supply cables supplied. Great product! It works just like it should and with little to no noise. Even when the fan kicks on it not loud at all.
