What Is the Difference Between Rated Power and Peak Power of an Inverter?

The rated output power is the continuous output power, which refers to the output power of the inverter under the rated voltage and current, which is the power that can be continuously and stably output for a long time.

The peak power is also called the maximum power, which refers to the maximum power value that the inverter can output in a very short time (usually within 20ms).

The peak power is usually 2-3 times the rated power.

Some electrical appliances or tools that use electric motors, such as refrigerators, washing machines, electric drills, etc., require a large current to drive at the moment of startup. Only when the peak output power reaches the peak power of the electrical appliance can it be turned on normally. Once the startup is successful, only a small current is needed to maintain its normal operation. As long as the rated output power reaches the power required for the stable operation of the appliance, the appliance can operate normally.

When purchasing an inverter, the rated power reference value is relatively large. If your electrical appliances consume a total of 1,000 watts for fans, TVs, etc., then you need to buy an inverter with a rated power of more than 1,000 watts. However, if the electrical appliance is an inductive load with a motor, the starting power of the electrical appliance must be considered when selecting the capacity of the inverter.
