To make easily graspable the output data on a power conditioner at every unit time and to improve the usability of the power conditioner, by using a calculation means which calculates the output data at every unit time that is optionally set.
A power conditioner 2A contains a control power supply 5, which generates the driving power of the conditioner 2A from the output power of a solar battery 1 and a connection part 6. The part 6 includes a calculation means 7A and a storage means 8A which stores various data calculated by the means 7A. The mean 7A carries on the integrating operations for the total integration generated energy after a solar battery power generation system is installed and from the first of installation of the system and then updating and storing the integration result via the means 8A. Furthermore, the means 7A calls the total integration generated energy out of the means 8A and calculates the integration generated energy at each unit time based on the total integration generated energy to store the calculation result in the means 8A. These stored various data are shown on a display means 3A.
