METHOD OF DIAGNOSING MALFUNCTIONING OF BYPASS DIODE IN SOLAR PHOTOVOLTAIC BATTERY

A method of diagnosing malfunctioning of a bypass diode in a solar photovoltaic battery system is provided. The method may include: collecting solar photovoltaic battery operation information indicating a solar photovoltaic battery operation state, from a signal of a solar photovoltaic battery detection unit, while maximum power point tracking control is performed with the solar photovoltaic battery system in operation; and determining whether or not the bypass diodes based on the collected solar photovoltaic battery operation information.
