Title:
Solar energy power generation system
Document Type and Number:
Japanese Patent JP6080290
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress explosive burning of lithium ion batteries housed in a power storage device in the event of a building fire.SOLUTION: A power conditioner 16 converts DC power photovoltaic-generated by solar cell modules 12 via a junction box 14 to AC power to be connected to a commercial AC system of a distribution board 22. A power storage device 18 stores DC power generated by the solar cell modules 12 and/or DC power converted from AC power of the commercial AC system, in a battery module housing a plurality of lithium ion batteries. When receiving a fire link signal transmitted by a home alarm 26 detecting a fire, an adapter device 28 transmits a fire detection signal to a system control section in the power conditioner 16 via a monitor device 20 to cause the DC power stored in the battery module of the power storage device 18 to be released down to a lower state of charge of the lithium ion batteries, so that explosive burning is suppressed when the fire spreads.
