CONTROL METHOD OF PHOTOVOLTAIC INVERTER BY SETTING DYNAMIC VOLTAGE AND ITS APPARATUS

摘要

PURPOSE: A method and apparatus for controlling a solar inverter are provided to maximize solar power generation regardless of weather by dynamically setting a voltage which determines a starting condition of the inverter. CONSTITUTION: A stop circuit unit(10) generates a stop signal for stopping a solar inverter. A subtracter(14) subtracts a stop power set value from generated power. A starting circuit unit generates a starting signal for starting the solar inverter. A subtracter(32) outputs a temperature difference by subtracting a temperature in a stop of the inverter from a current temperature. A subtracter(40) outputs the subtracted result by subtracting a starting voltage from a power voltage.
