PURPOSE: A distribution box control device in a grid-connected street light system perform efficient power supply using natural energy and reliably operate a street light without the cut-off of power. CONSTITUTION: A control unit (210) controls the on and off of each street light according to a street light lighting schedule received from a control server. The control unit tracks the failure of a power generation device by monitoring generated power at each street light received from each street light control device. A storage unit (230) stores identification information including a group address in which each street light is included and an individual address of each street light. A display unit (280) displays both the monitored result provided from the control unit and the identification information of the street light. A watchdog timer circuit unit (270) performs a reset function by itself by detecting the failure of the control unit.
