Battery Backup Power

Battery Backup Power can be added alongside an existing grid intertied solar power system. When the grid goes down, a grid-tied solar system goes down too, unless you have added a bank of batteries and planned for an additional source of electricity generation. The extra source of electricity may be a gas generator or additional solar panels. In grid-connected systems, the only additional equipment is a power-conditioning unit (inverter) that makes a turbine output electrically compatible with the utility grid. No batteries are needed. For safety, batteries should be isolated from living areas and electronics because they contain corrosive and explosive substances. Lead-acid batteries also require protection from temperature extremes.
