PROBLEM TO BE SOLVED: To prevent a plurality of power converters from stopping by simultaneously detecting an abnormality, developing stress and reducing a generated electric energy by repetition of stop and start. SOLUTION: This photovoltaic power generator is provided with a plurality of solar battery arrays 11 to 13 and a plurality of power converts 21 to 23 to be provided by every one of the solar battery arrays 11 to 13, to convert DC output power of each of the solar battery arrays 11 to 13 into AC power and to output the converted power to a commercial power system 5 and prevents simultaneous stop of the plural power converters 21 to 23 even when a predetermined abnormality is generated. Furthermore, generated electric energy of each of the solar battery arrays 11 to 13 is different, a condition to be easily stopped by the specified abnormality is set for the solar battery array with the lowest generated electric energy. |
