Title:
太陽光発電システム用パワーコンディショナ
Document Type and Number:
Japanese Patent JP3581093
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power conditioner for a photovoltaic power generation system capable of displaying information related with photovoltaic power generation without supplying a power from a commercial system power source side when any power is not generated by a solar battery at night. SOLUTION: This system is provided with an inverter part 2 for converting a DC power obtained from a solar battery 1 into an AC power, and for supplying the converted AC power to a load while being linked with a commercial system power source 3 and a display part for displaying the information related with a photovoltaic power generation. A remote controller 8 equipped with the display part is allowed to operate with a power generated by the solar battery, and to receive the display data from a control circuit 7 just before the operation is stopped, and store the display data in an inside memory when any power is not generated by the solar battery at night. Then, while the operation is stopped, the power is supplied from an auxiliary power source part (D1, R1, C1) to the remote controller 8, and the information related with the photovoltaic power generation is displayed at the display part, and the remote controller 8 is allowed to operate without consuming any power from the commercial system power source.
