SOLAR INVERTER, AND METHOD FOR CONTROLLING SOLAR INVERTER

摘要

PURPOSE: A solar light inverter and a method for controlling the same are provided to prevent the generation of a non-detection zone with respect to the isolated operation of the inverter. CONSTITUTION: A measuring part(110) measures a voltage and a current outputted from an inverter to the outside. A power calculating part(120) calculates ineffective power based on measured voltage and current. An operating part(150) compares the size of calculated ineffective power and the size of reference effective power. If the size of the calculated ineffective power is lower than the pre-set ratio of the size of the reference effective power, a signal generating part(170) generates the switching signal of the inverter in order to output ineffective power from the inverter to the outside. The size of the outputted ineffective power is the same as the size of the calculated ineffective power.
