PURPOSE: A junction box is provided to separately check whether a solar module is in an abnormal state by monitoring the operation of the solar module. CONSTITUTION: A positive port(211) is connected to the positive terminal(221) of a junction box(200) through a positive wire. A negative port(214) is connected to the negative terminal(222) of the junction box through a negative wire. A current detector is arranged on the positive or the negative wire. A voltage detector is connected between the positive wire and the negative wire. A disconnecting part(260) is arranged on the positive or the negative wire in order to disconnect a current. A control part(250) controls the disconnecting part based on the detection value of the voltage detector and the current detector. |
