1. A solar control device for controlling a solar power generation system, the solar power generation system having at least one first group including a solar panel and a first DC/DC converter and at least one second group including a second DC/DC converter and a battery, at least one of the at least one first group and the at least one second group being a plurality of the first groups or the second groups, the first DC/DC converter being configured to output electric power generated by the solar panel to a first power line, the second DC/DC converter being configured to output electric power received via the first power line, to a second power line, the battery being connected to the second power line, the solar control device comprising
an electronic control unit configured to:
set an output command value for the second DC/DC converter such that the output command value periodically switches between a first value and a second value that is smaller than the first value, when an output of the second DC/DC converter is equal to or smaller than a threshold value; and
determine that the second DC/DC converter is abnormal when the output command value and the output of the second DC/DC converter satisfy a predetermined condition.
