Disclosed is a smart connection board of a solar energy generation system which can monitor excess and deficiency of the amount of power in a remote location by comparing solar generation power, input power of an electricity supplier, and consuming power. The connection board comprises: a signal input unit configured to receive an input signal by sensing a DC voltage and a DC current of DC power to be transmitted to an inverter of a solar energy generation system, sensing an AC voltage and an AC current of AC power, which is generation power, to be transmitted from the inverter to the connection board, and sensing an AC voltage and an AC current of AC power, which is input power of a power supplier, inputted into the connection board from an outside; a central processing unit configured to calculate the amount of power of at least one of the generation power, the input power, and the consuming power using the AC/DC currents and voltages in which the signal input unit receives; a memory unit configured to store the amount of power calculated in the central processing unit; and a communications unit configured to transmit the calculated amount of power to an output unit of a remote location. According to the invention, the connection board has a benefit of managing a power quality by using current and voltage measured in a real time. |
