I-V CURVE MEASUREMENT DEVICE AND I-V CURVE MEASUREMENT METHOD FOR SOLAR BATTERY, POWER CONDITIONER FOR PHOTOVOLTAIC POWER GENERATION SYSTEM, AND PHOTOVOLTAIC POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a technology capable of positively measuring an I-V curve of a solar battery by measuring the I-V curve at a timing when the power generated by the solar battery has reached a threshold value.SOLUTION: Generated power from a solar battery is acquired, a value based on the acquired generated power is compared to a predetermined threshold value, and it is determined whether or not a value of the generated power is greater than the threshold value. When the value based on the generated power is determined to be greater than the threshold value, an I-V curve of the solar battery is measured.SELECTED DRAWING: Figure 2
