<p>An open-circuit voltage control system which is used in a photovoltaic power system that includes a string 7 that includes solar battery panels connected in series and a switch 5 that connects and disconnects a path for supplying a direct-current voltage generated at the string to a load and which controls an open-circuit voltage of the string and which includes an open-circuit voltage measurement device 3 which measures an open-circuit voltage of the string in an open state where the string and the load are not connected to each other, a drive control device 11 which controls an output voltage from the solar battery panels, and a calculation control device 4 which outputs a signal for controlling the drive control device so that the open-circuit voltage may reach a specific voltage value not lower than an operable voltage of the load but lower than a breakdown voltage of the photovoltaic power system based on the open-circuit voltage measured by the open-circuit voltage measurement device, with the string and the load being in the open state.</p> |
