摘要： PROBLEM TO BE SOLVED: To miniaturize a measuring device and reduce its weight and at the same time improve portability, by utilizing the input capacitor of a power conversion device for the load of a solar cell. SOLUTION: When solar cell output characteristics are to be measured, a DC circuit breaker 6 in a connection box 2 is turned off, an input capacitor 11 for an inverter 12 is completely discharged by a discharge resistor, and then a solar cell output characteristic measuring device 30 is connected in series between the connection box 2 and the inverter 12. Then, the DC circuit breaker 6 is turned on and a charge current that flows into the capacitor 11 and the voltage between the terminals of the capacitor 11 are continuously measured by a current detection means 41 and a voltage detection means 42. Then, the values of the measured current and the voltage between terminals are sampled by an A/D converter 34, and a result that is detected by a light detection means 33 and a temperature detection means 36 is also added to the result before being processed by a central processing unit 35 and being displayed by a display means 37, thus eliminating the need for providing a measurement capacitor in the measuring device 30.
