Overview

Periodically, whether or not a battery array is employed, there are times when the wind turbine and/or solar arrays are generating more electrical energy than can be consumed, such as when the batteries are fully charged, or there is no need to use the excess electrical energy. This excess electrical energy must then be "diverted" to some other electrical load so as to a) not damage the battery array; b) prevent a build-up of electrical energy with no place to go. Even with installations that are "grid-tied", during those instances when the public grid is experiencing a power failure, the RETS must divert its excess electrical energy to an alternative electrical load, because during a public grid power failure, the RETS must be separated from the grid.
