The battery energy storage system's (BESS) essential function is to capture the energy from different sources and store it in rechargeable batteries for later use. Often combined with renewable energy sources to accumulate the renewable energy during an off-peak time and then use the energy when needed at peak time. This helps to reduce costs and establish benefits for the user. BESS has flexibility with grid connection and can be operated in local mode when the grid is not available.
