Energy Storage System and Its Working

To learn deeply about energy storage systems, you need to be well aware of energy storage and its working. As for energy storage, it is the capture of energy produced at one time for usage at some other time later to lessen imbalances between energy demand and energy production. There is a device that stores energy called a battery or an accumulator (as in the case of SunFusion, it uses batteries for the storage).

As for the working of the energy storage system, the battery storage system (as it is available at SunFusion) is charged by electricity generated from renewable energy such as solar power or wind. The intelligent battery software, which is placed for the functioning, uses algorithms in order to coordinate energy production and then the computerized control systems which are used to decide when to keep the energy to provide reserves or release the energy to the grid for the ultimate use.
