With the large-scale global deployment of DC power systems such as photovoltaic (PV) and energy storage facilities, safety risks from lightning surges, switching overvoltages, and other electrical disturbances continue to rise.Our product RDU8DC Series Surge Protective Device (SPD), delivering precise DC protection technology and highly reliable performance to provide professional overvoltage safety solutions for PV power plants, energy storage systems and more.
Voltage stability in DC power systems directly impacts equipment lifespan and power generation efficiency. Surge shocks caused by lightning induction and grid fluctuations are among the primary triggers for PV inverter damage and energy storage battery thermal runaway. The RDU8DC Series SPD is deeply optimized for DC scenarios, addressing protection pain points at a technical level:
◆ Precisely Adapted to DC Systems: Designed specifically for 1000VDC high-voltage DC applications, it perfectly matches the voltage requirements of PV modules and energy storage battery packs.
◆ High Surge Current Handling Capacity: It can withstanding severe lightning strikes and complex grid fluctuations to significantly reduce equipment damage rates.
◆ Low Residual Voltage for Safety Assurance: With a residual voltage (Up) ≤ 4.0kV, it ensures the equipment-side voltage remains within safe thresholds during surge events.
Thanks to its professional protection performance, the RDU8DC-B40 DC SPD has become a safety staple across multiple DC scenarios:
● Photovoltaic Power Plant Scenarios: Protects PV combiner boxes and string inverters, reducing the impact of surges on power generation efficiency and lowering operational costs.
● Energy Storage System Scenarios: Provides overvoltage protection for energy storage battery cabins and PCS converters, mitigating the risk of battery thermal runaway and ensuring stable system operation.
● Telecom Base Station Scenarios: Protects DC rectifiers and battery banks in base stations, maintaining continuous communication network operation during extreme weather.
