<P>PROBLEM TO BE SOLVED: To improve economical efficiency of an uninterruptible power supply using photovoltaic generation power and midnight power, by using the uninterruptible power supply capable of utilizing both commercial power and power storage battery power without intermission. <P>SOLUTION: An uninterruptible power supply with photovoltaic power generation capable of utilizing both commercial power and storage battery power without intermission comprises: a structure part which utilizes AC power supply output while charging a storage battery with DC power converted from AC power supply power and performs switching so as to output AC power converted from power of the storage battery when a power failure occurs, in order to utilize commercial power at all times; and a structure part which converts power from the storage battery to the AC power after charging the storage battery with DC power converted from the AC power supply power by timer setting in specific time zone or after charging the storage battery with photovoltaic power generation power, and performs switching so as to utilize the commercial power when voltage of the storage battery becomes lower than a predetermined voltage, in order to utilize the power of the storage battery charged with the photovoltaic power generation power and midnight power. <P>COPYRIGHT: (C)2013,JPO&INPIT |
