A grid-tied electrical system, also called ''tied to grid'' or ''grid tie system'', is a semi-autonomous electrical generation or grid energy storage system which links to the mains to feed excess capacity back to the local mains electrical grid. When insufficient electricity is generated, or the batteries are not fully charged, electricity drawn from the mains grid can make up the shortfall. When batteries are used to store, the system is called battery-to-grid (B2G), which includes vehicle-to-grid (V2G). ==How it works== (詳細はinverter which is grid tied. The inverter monitors the alternating current mains supply waveforms and generates electricity that is phase matched. The DC electrical system is attached to the mains via this mechanism. Because the local system is phase matched, electricity can be drawn from the mains in the situation of a generating shortfall or discharge in batteries. When phase matching does not occur, most inverter (s), via software controls, tailored to end user application, courtesy power access is possible when the grid goes down. Power scavenging software via monolithic devices can be made operational when the grid fails to accept the power being continuously provided to the grid but rejected --essentially a "black out". When the sun shines, power can be made, grid-tied electrical systems can potentially maximize upon this effect when tethered to other "net-metered" entities, such as the Internet. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Grid-tied electrical system」の詳細全文を読む スポンサード リンク
