| description | To devise the use of a hybrid inverter as a main body well in Japan that is spread abroad and available at a low price while making the best use of a merit in terms of cost as it is.SOLUTION: A semi-autonomous solar power generation self-consumption system includes: a hybrid inverter connected to a solar power generation panel; a step-down transformer provided in an electric path between the inverter and a load and whose load side is adjusted for a single-phase three-wire output; and an automatic converter between an inverter output voltage and a system voltage. In the case of on-grid, the automatic converter is constituted by the inverter, and a system is connected to in of the inverter in a form of 200 V single-phase two inputs. Single-phase two outputs are output from out; however, an inverter output voltage is supplied "normally" while the system voltage is supplied "in times of shortage". Since there is a voltage difference, in the transformer, a tap voltage is adjusted according to a type of a voltage on an input side, single-phase three outputs from the transformer are set so as to match a normal rated voltage regardless of whether single-phase two outputs are the inverter output voltage or the system voltage.SELECTED DRAWING: Figure 3
【課題】海外で普及している廉価で入手可能なハイブリッドインバータを主体として、コスト面でのメリットをそのまま生かしつつ日本で上手く使えるように工夫する。【解決手段】太陽光発電パネルと接続されたハイブリッドインバータと、インバータと負荷との間の電路に設けられ、前記負荷側が単相３線出力用に調整されている降圧用の変圧部と、インバータ出力電圧と系統電圧との間の自動切換器を備える。オングリットの場合には、自動変換器をインバータで構成し、系統がインバータのｉｎに２００Ｖ単二入力の形で接続されている。また、ｏｕｔから単二出力されるが、「常時」はインバータ出力電圧が、「不足時」には系統電圧がそれぞれ供給される。電圧差があるので、変圧器では入力側の電圧の種類に合わせてタップ電圧が調整されて、単二出力がインバータ出力電圧であれ系統電圧であれ、変圧器からの単三出力は通常の定格電圧に合うようにセットされる。【選択図】図３ |
