<p>The present invention relates to a smart hybrid power supply system which can solve the shortage of electricity through electricity management, save an electricity bill, and reduce environment pollution by omitting an installation of emergency generator. The invention comprises: a solar cell for generating and outputting an electric energy by receiving incident solar energy; an inverter unit for controlling a voltage level by receiving an electric energy generated from the solar cell, and for converting to an AC power and outputting thereof; a battery unit for receiving a DC power, which is adjusted to a rated voltage, from the inverter unit, and for storing thereof; a battery management unit for managing the stored DC power in the battery unit; a switching unit for selectively controlling an AC power, which is entered to an external electric power system, and an AC power, which is converted and outputted from the inverter unit, and for supplying thereof to the house load; and a monitoring unit for monitoring the battery management unit, the inverter unit and the switching unit, and for supplying the electricity stored in the battery unit to the house load in the absence of the electric energy generated from the solar cell or in the case of non-supply of electricity from the electric power system and for monitoring thereof.</p> |
