PROBLEM TO BE SOLVED: To cope with various kinds of load by connecting an AC load terminal where load is to be connected and a coupling terminal where other solar battery device of the same constitution is to be connected in parallel, for the output terminal part of the solar battery device where an output control means and a conversion means are provided integrally. SOLUTION: When insulation increases, DC power of fixed voltage is supplied to an conversion means 7 and a charging and discharging control means 8 through an output control means 6. In the conversion means 7, it is converted into specified AC power, and it is supplied to external AC load 9 through the AC load terminal 11 within the output terminal 5. Since the conversion means 7 is provided with a plurality of coupling terminals 13, a large quantity of power can be supplied from the AC load terminal 11, connecting other solar battery device of the same constitution to the coupling terminal 13. Furthermore, the generated power supplied from the solar battery 1 is supplied to the storage battery 4 through a charging and discharging means 8. Since the storage battery 4 can be charged from an external power source through the charging terminal 17, the power can be supplied to the external AC load 9 through the conversion means 7 from the storage battery 4. |
