Grid-Connected / Off-Grid Switching Cabinet

During normal operation, the system remains connected to the grid to supply power to loads. In the event of grid failure or voltage drop, it rapidly switches to the battery energy storage system to ensure continuous power supply. Compatible with PV systems, PCS, and other energy devices, the cabinet is designed for multi-energy complementary applications, enabling AC bus integration, coordinated operation, and intelligent interaction among energy storage systems, photovoltaics, and loads.
