Title:
POWER SOURCE DEVICE BY PARALLEL OPERATION
Document Type and Number:
Japanese Patent JPS6024612
Kind Code:
A
Abstract:
PURPOSE:To operate efficiently and economically a solar battery by providing an electric water heater being an accumulation load for converting a surplus portion of a generated output of the battery to heat and accumulating it, on an output of the battery, by separating it from the load. CONSTITUTION:A titled device is constituted by connecting an electric water heater 7 to an input side of an invertor 2, namely, an output side of a solar battery 1, separately from a system load 5. According to this constitution, even if the battery 1 is operated in an optimum state, a time zone in which a generated output of the battery 1 exceeds a demand electric power is generated by a variation of a demand electric power of the load 5. Such a fact as the generated output has exceeded the demand electric power is detected by a detecting part and displayed on a display part 6, and when room is generated in a supply electric power to the load 5 and a generated output of the battery 1, and it is informed to a demander to be in a state that the power can be consumed a little more, a surplus portion of the generated output of the battery 1 is converted to heat by the electric water heater 7 and accumulated. Therefore, the surplus portion is regenerated effectively, and the effeciency is raised.
