INTELLIGENT PHOTOVOLTAIC MODULE CONTROLLER AND CONTROL METHOD THEREOF

Disclosed herein are an intelligent photovoltaic module controller used in a photovoltaic power generation system to connect two photovoltaic modules in series or in parallel and a method for controlling the same. According to the present invention, it is possible to maximize power generation efficiency by controlling series/parallel connection based on changes in current flowing through a pair of external connection terminals of the photovoltaic module controller or a string connecting multiple photovoltaic module controllers in series.
