A battery storage system requires a charging regulator, which controls the flow of power from the source of electricty to the battery. Proper charging insures minimal battery damage and maximum life of the battery. Proper charging insures minimal battery damage and maximum life of the battery. Typically a wind turbine comes with a charge regulator specific to the wind turbine. An inverter is needed to convert DC power to AC power.
Most consumers buy and assemble individual components when building a renewable system.
Some, however, purchase an integrated system that includes all of the components of the storage system. In addition to having everything in one unit, a power panel may be helpful in meeting local building inspections and codes. Secondary batteries are a type of battery that allows for repeated charging and discharging cycles. This is mainly why they are the battery of choice for hybrid systems. They are commonly used in tractors and cars.
