<P>PROBLEM TO BE SOLVED: To provide a solar power generating system for detecting its abnormal state from its power generating state and effectively utilizing energy generated by a solar cell panel. <P>SOLUTION: A display has a power converter belonging to the same solar power generating means as the display, a receiving section for receiving power generation data transmitted from other power converter, and a memory for comparing the received power generation data and sequentially storing a ratio of power generated by a DC power supply belonging to the same solar power generating means and power generated by other DC power supply, determines that the solar power generating means causing a change of the ratio is abnormal if the change of the ratio exceeds a predetermined range, and further displays abnormality. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
