Description
The INPPCS converter enables AC/DC conversion between the grid and batteries, facilitating bidirectional energy flow. It serves as the primary execution unit and core component in energy storage systems. Through advanced control strategies, it manages battery charging/discharging, controls power rates, and switches between grid-connected and off-grid modes. It also offers comprehensive protection functions, such as islanding protection, DC overvoltage protection, and low voltage ride-through, meeting both grid-connected and off-grid requirements.
