In stand-alone photovoltaic systems, the electrical energy produced by the PV array can not always be used when it is produced. Because the demand for energy does not always coincide with its production, electrical storage batteries are commonly used in PV systems. The primary functions of a storage battery in a PV system are to:
Most of the existing photovoltaic energy storage systems are based on a single centralized conversion circuit, and many research activities concentrate on the system management and control circuit improvement.
A battery is connected in a PV system and to electrical loads at the terminal posts. In a lead-acid battery the posts are generally lead or a lead alloy, or possibly stainless steel or copper-plated steel for greater corrosion resistance. Battery terminals may require periodic cleaning, particularly for flooded designs.
