Junction box, energy system and method for controlling the same

摘要

A junction box for connecting a power supply unit is disclosed. The junction box includes a first connection terminal, a second connection terminal, a serial carrier interface module, and a control module. The first connection terminal and the second terminal are utilized to connect the junction box and another junction box in a serial connection. The serial carrier interface module is electrically coupled to the first connection terminal and the second connection terminal for the transmission of a carrier and a DC power, which is provided from the power supply unit. The control module is electrically coupled to the serial carrier interface module for receiving the carrier and for controlling of the transmission of the DC power according to the carrier. A power system which employs the junction boxes and a method for controlling the power system are also disclosed.
