PROBLEM TO BE SOLVED: To obtain a solar power generator efficiently using the generated power. SOLUTION: In this solar power generator, a virtual optimal operating voltage VA, MPPT(maximum power point tracking) minimum voltage VL, MPPT maximum voltage VH to be used at the time of operating MPPT control are calculated just before the activation of an inverter circuit, and then the inverter circuit is activated. Afterwards, whether or not an unstable operation is generated is judged (a step 200), and when it is generated, the number of times of the unstable operations generated since that time until a second prescribed time passes is counted, and when the count value is made larger than a first prescribed value, a second prescribed value is added to the values of the voltages VA, VL, and VH or the like calculated just before the activation of the inverter circuit (steps 204-218). |
