<P>PROBLEM TO BE SOLVED: To reduce stoppage of a server as much as possible, even at service interruption of a system. <P>SOLUTION: A power conditioner 6 is so constituted of operations, where: direct-current power generated by a photovoltaic power generating system is boosted by a step-up chopper 7; and the boosted direct-current power is converted into alternating-current power at an inverter 8 and is connected to an alternating-current power supply system 11. Also, the power conditioner is so constituted that a LAN board 21 can be incorporated. The LAN board is selectively supplied with direct-current power, obtained by regulating the voltage of direct-current power generated by the photovoltaic power generating system or direct-current power obtained by converting alternating-current power from the system through an AC/DC converter 32, and is provided with an address management unit, a memory, a clock unit, and a computation unit and is provided with the functions of a server. <P>COPYRIGHT: (C)2007,JPO&INPIT |
