The present invention relates to a household smart energy storage system. The system includes: an AC/DC converting unit connected to a commercial AC power service wire inputted to a home service wire to convert AC power into DC power; a battery module charged with the DC power outputted from the AC/DC converting unit; a DC/AC converting unit for converting the power charged in the battery module into an AC voltage and outputting the AC voltage through a first load terminal; a DC/DC converting unit for converting the power charged in the battery module into a set DC voltage and outputting the DC voltage through a second load terminal; a voltage detecting unit for detecting a voltage of the power service wire; a power control unit for controlling the AC/DC converting unit such that the battery module is charged and controlling the DC/DC converting unit and the DC/AC power converting unit such that the power charged in the battery module is supplied to the first or second load terminal when the voltage detected by the voltage detecting unit is equal to or less than a set level or corresponds to a discharge condition. Thus, the household smart energy storage system can supply AC and DC power to loads while providing an energy storage function, so that convenience in use is provided. |
