SMART CONNECTION BOARD OF SOLAR ENERGY GENERATION SYSTEM AND MEASURING METHOD OF POWER GENERATION EFFICIENCY OF INVERTER USING IT

摘要

The present invention relates a smart connection board of a photovoltaic system and a method of measuring power generation efficiency of an inverter using the same. The smart connection board of a photovoltaic system includes a signal input unit to detect DC voltage and current of DC power to be transferred to an inverter, detect AC voltage and current of generation power (AC power) to be transferred to a distribution switchboard from the inverter, and detect and receive AC power and current of power supply input power (AC power) introduced to the distribution switchboard from the outside; a central processing unit to calculate at least one kind of electricity amount information among generation power, introduction power, consumption power, and a power generation efficiency of the inverter based on the AC/DC voltage and current received by the signal input unit; a memory to store the electricity amount information calculated by the central processing unit; and a communication unit to transmit the electricity amount information calculated by the central processing unit to an output unit.
