摘要
The present invention relates to an apparatus and method for analyzing a solar cell string output performance of a photovoltaic system, and more particularly, an inverter of a photovoltaic system includes a plurality of solar cell strings and a reverse flow prevention diode at each string output stage. Is connected in series, the device for analyzing the solar cell string output performance of the photovoltaic power generation system configured to integrate the power from the plurality of solar cell strings to supply to the input terminal of the inverter, the string provided for each string A string monitoring unit configured to monitor voltage current values from the voltage current sensor for each string; And, the string monitoring unit is connected to the interrupt line and the data line of the inverter to control the inverter, by detecting the abnormality of the solar cell string that is not found in the normal operating state and the grid output stage is connected (hot line ) And an apparatus and method for analyzing the solar cell string output performance of the photovoltaic system that can grasp the solar cell string output performance by output power.
