PURPOSE:To provide a system linking demander-systems to a power-system wherein the burdens of demanders are made light, and its DC-AC conversion efficiency is made high, and further, its cost is made low, and moreover, both the maintainings and managings of the qualities of powers are made easy. CONSTITUTION:In a system for linking demander-systems to a power-system, DC powers outputted from a plurality of solar batteries 55 of demanders are concentrated in a summarizing way on both DC-AC separation device 2 and power-system linking inverter 3, via an energy meter 53 and AC distribution lines 51, 52. In the DC-AC separation device 2, the DC powers are separated from the AC distribution lines 52, and are outputted to the power-system linking inverter 3. In the power-system linking inverter 3, the DC powers are converted into an AC power, and the AC power is outputted to the AC distribution line 51. Thereby, the outputs of a plurality of solar batteries 55 of the demanders can be concentrated in a summarizing way on the one power-system linking inverter 3, without the provision of independent DC lines. |
