PROBLEM TO BE SOLVED: To solve the problem of the conventional photovoltaic power generation system having difficulty in recording various types of characteristics and conducting effective failure analysis, based on the recorded characteristics. SOLUTION: When a control circuit 34 detects failure in the system, an inverter stoppage circuit 344, first stops a power conditioner 30 and transmits an error code to a detection value selecting section 345. The detected value, corresponding to detection items selected according to the type of the failure is recorded in a failure recording memory 347, together with other failure data. Only the detected value selected according to the type of the failure is recorded, thus memory capacitance for recording is saved, and efficient failure analysis is conducted. |
