An intelligent hybrid inverter or smart grid inverter is a new generation of dedicated uninterruptible power supply (UPS) applications using renewable energy for home consumption, especially for solar photovoltaic installations. Electricity from solar panels is generated only during the day, with a peak production around midday. This electricity is fluctuating and not synchronized with the electric consumption of the household. To overcome this gap between what is produced and what is required during the evening when there is no solar electricity production, it is necessary to store energy for later use and manage energy storage and consumption in an intelligent (smart grid). With the development of systems using renewable energy and rising prices of electricity, private companies and research laboratories have developed smart inverters to enable correlation between energy production and consumption.〔(French: Online Course in power, DC/AC conversion, inverters )〕 == Principle == The function of a (smart-grid) is enabling selection and orientation of renewable energy, energy from the grid and energy storage based on consumption. Unlike conventional inverters, rather than systematically storing energy in batteries (with significant loss of yield >20%),〔(Performance of a battery (Rendement d'une batterie) )〕 hybrid inverters store energy only when necessary, e.g. when there is more production than consumption. This system also allows choosing whether electricity from photovoltaic panels should be stored or consumed through an internal intelligent apparatus control unit. This is possible through a technique that adds different energy sources (phase coupling: on-grid or grid-tie techniques) and the management of stored electricity in the battery (off grid technology). Hybrid inverters therefore operate on grid (grid-tie) as well as off-grid, hybrid (both on-grid and off-grid at the same time) and Backup (in case of a black out). According to the E.R.D.F. (French Electric Network) smart inverters are the future of photovoltaic solar panel installations dedicated to energy self-use, or auto-consumption of energy. 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「Intelligent hybrid inverter」の詳細全文を読む スポンサード リンク
