1. Field of the Invention
The present invention relates to a solar battery controller.
2. Description of Related Art
A technique of calculating a maximum power point in solar battery arrays in total by connecting the solar battery arrays, which are connected in series to each other, to monitoring solar batteries corresponding to the number of solar battery arrays in parallel and detecting short-circuit currents of the monitoring solar batteries and open-circuit voltages of the solar battery arrays is known (for example, Japanese Patent Application Publication No. 61-281316 (JP 61-281316 A)).
However, in the technique described in JP 61-281316 A, the timing of detecting the short-circuit currents of the monitoring solar batteries and the open-circuit voltages of the solar battery arrays is not described. Accordingly, when a solar battery module is mounted on a moving object, the maximum power point calculating timing cannot be appropriately set and thus there is a possibility that an increase in computational load or a delay in the maximum power point calculating timing will occur.
