The present invention provides a distribution board system capable of economizing and miniaturizing through the minimization of functional overlaps in the distribution board system structure. The distribution board system comprises: a plurality of lower modules, each of which includes a communication unit and has the capacity for extension by adding a functional module; a digital power meter, which includes a lower communication unit for communicating with the communication unit of a lower module, an upper communication unit for communicating with an upper monitoring board, and a meter unit that adds up generated energy by calculating and accumulating electric power based on measured voltage and current of a power system; and a communication network operated on an industry communication protocol, which allows communicative access between the communication unit of the lower module and the lower communication unit of the digital power meter.
