Power DC SPD

Photovoltaic and storage equipment is typically installed outdoors and exposed to risks of direct and induced lightning strikes. SPDs can divert surge currents in the system to the ground, limiting voltage across equipment terminals and protecting components from damage, thereby extending their service life. Additionally, as energy storage batteries are critical devices, their internal battery management systems (BMS) have high requirements for the stability of operating voltage and current. SPDs can effectively suppress surge voltages and currents in DC systems, preventing energy storage batteries from experiencing severe faults such as overheating, bulging, leakage, or even explosion due to overvoltage, thus ensuring the safe operation of energy storage equipment.
