PROBLEM TO BE SOLVED: To make it possible to use excess current generated by a solar battery effectively for power to be consumed by an electric equipment such as an air conditioner, by making a demand function of the electric equipment effective when an integrated value stored in a storing section falls below a specified value. SOLUTION: A distribution panel 7 for housing, being serially connected to a purchased power meter 5 and a sold power meter 6, supplies power to each electric equipment in user's house. The output of a system link generator 2 is inputted into the distribution panel 7 for housing and excess power which is not used in the house is supplied to the system through the purchased power meter 6 and the sold power meter 5. Power can be sold to the system only when the voltage of AC power outputted from the system link generator is higher than that of the system. Therefore, the power consumed by the electric equipment can be controlled by making a demand function of the equipment effective based on an integrated value of power generated by a solar battery 1 and the power consumption of the equipment. |
