Rated power and peak power are different due to their meaning. The rated power determines the load capacity, and the peak power determines whether the appliance can be started.

What is the difference between rated power and peak power of inverter?

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

Peak power, also known as maximum power, refers to the maximum power value that the inverter can output in a very short time (usually within 20ms).

Peak power is usually 2 to 3 times the rated power.

Some electric appliances or tools using electric motors, such as refrigerators, washing machines, electric drills, etc., at the start of the moment need a large amount of current to promote, only the peak output power to reach the peak power of the start of electrical appliances, electrical appliances can start normally. Once started successfully, 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 electrical appliance, the electrical appliance can operate normally.

When purchasing the inverter, the reference value of rated power is relatively large. If your electrical appliances consume a total of 1000 watts, such as fans and TV sets, then you need to purchase the inverter with rated power of 1000 watts or more. But if the electrical motor with the inductive load, choose the capacity of the inverter, it must consider the starting power of the electrical appliances.
