Translations:PV system types/6/en

PV systems installed in areas that lack a grid connection are called stand-alone systems but are also commonly referred to as battery-based or off-grid systems. These systems take many different forms, but they almost always incorporate some type of storage, typically a battery bank, and one or more charging sources. In addition to solar PV, these systems may also incorporate a generator, wind, or hydro. Stand-alone systems can use alternating current and direct current as charging sources and can supply alternating and direct current for loads. The various different stand-alone system types used for small-scale projects are depicted below. More complex designs used for microgrids or very large systems, like those that incorporate alternating current (AC) coupled charging, are excluded.
