The ESHVB series is a robust High Voltage Control Box designed as a critical safety and control node for advanced energy storage systems. This highly integrated unit seamlessly incorporates circuit breakers, contactors, fuses, circulating current control circuits, current sensors, a secondary BMS (ESBCM), and switching power supplies into a single high-voltage box. This comprehensive integration realizes the communication function between the high-voltage box itself and the ESBMM, the ESMU, and the energy storage converter (PCS). Built to realize the control, protection, and data communication functions of the energy storage battery rack, the ESHVB ensures your power system operates with maximum safety and efficiency. Furthermore, the internal configurations can be fully customized according to the actual needs of the project.
Provides essential rack-level high-voltage protection for large power plants.
Ensures secure energy routing and fault isolation for industrial microgrids.
Safeguards battery racks connected to fluctuating solar and wind sources.
Highly adaptable configurations tailored to specialized energy requirements.
