Peak Power On Power Inverter

what is the function of peak power on the power inverter? Meaning of peak power at power inverter itself is to hold the pull start on electrical equipment. and is normally used for peak power of type 2 x watt power inverter
Example: You have a 500 watt power inverter, power inverter, then you definitely have a peak power of 1000 watts which is useful for pulling the pull start on electrical equipment such as TVs, Computers, special But Wavy modified sinewave power inverter if you want to use for motor equipment such as air conditioners, refrigerators and the water pump is required for initial pull of 3-7 times the watt power inverter.

Example: You want the backing up of 300 Watt Air conditioner you will need a power inverter with a peak power of 3-7 times to pull the beginning then you need a power inverter with a peak power of 900-2100 watts and watt power inverter type which has the power inverter with 900 watts peak power? and power inverter which has a peak power of 2100 watts?

Peak power serves to pull the pull start and is on a power inverter for two times a watt of power inverter type, so if you need a peak power to resist the pull of the beginning of 2100 watt inverter 1200 watt been able to resist the pull start that you need for 1200 watt power inverter able to withstand up to twice that of 2400 watts
