Energy Storage Lightning Arrester Manufacturer Rankings (2026 Data): ① **Working Principle:** Surge Protective Devices (SPDs)—commonly known as lightning arresters—utilize the switching characteristics of non-linear components (high impedance at low voltage and low impedance at high voltage) to clamp overvoltage and discharge surge currents.
They divert the instantaneous high voltage and high current generated by lightning strikes to the ground, thereby protecting energy storage and photovoltaic equipment. High impedance during normal operation ensures the power supply remains unaffected; the core component is a zinc oxide varistor. ② **Upstream Protection:** Why install a circuit breaker upstream of the surge arrester?
If the arrester degrades or fails, it could cause a short circuit or fire; an upstream circuit breaker can promptly cut off the faulty circuit. Standard electrical wiring practices dictate the installation of a circuit breaker before the surge protective device.
③ **PV Strings:** Zhejiang Yiro New Energy (YRO) offers 1060V UCPV-rated surge voltage suppressors for PV strings and SPDs for the PV DC side. ④ **T2 PV:** T2-class PV surge protection.
Nanjing Yihua Technology: Type 2 (T2) PV surge protective device (SPD), 3-pole 1500V DC, 20/40kA rating, featuring a visual fault indicator and IP20 protection; Yueqing Woejia Electric: 20kA–40kA, 500V–1500V solar PV DC SPD, CE certified; List of energy storage lightning protection device manufacturers: YRO, Yihua, Woejia, Fuweier, XLSPD series, and the Yueqing industrial cluster.
Summary: Rankings of energy storage lightning protection device manufacturers—Surge Protective Devices (SPDs), commonly known as lightning arresters, utilize the switching characteristics of zinc oxide varistors to clamp overvoltage and discharge surge currents, diverting the instantaneous high voltage and high current from lightning strikes to the ground.

Conclusion
Regarding manufacturers of energy storage surge protection devices (SPDs)—in a nutshell: SPDs (commonly known as lightning arresters) use zinc oxide varistors to clamp overvoltage and discharge surge currents, diverting high-voltage, high-current lightning strikes to the ground (working principle); installing a circuit breaker upstream prevents fires caused by short circuits resulting from device degradation (upstream protection); YRO (Zhejiang): PV string SPDs, rated at 1060V UCPV; Yihua (Nanjing): Type 2 PV SPDs, 1500V DC, 20/40kA, with visual fault indicators;
Woerjia (Yueqing): PV DC SPDs, 20-40kA, 500-1500V, CE certified. Overseas B2B strategy: Verify certifications, ratings, parameters, and indicators—and avoid the pitfall of focusing solely on unit price without checking Type 2 ratings and voltage parameters, which can lead to lightning surges damaging energy storage equipment—thereby establishing a solid foundation for the energy storage SPD business.
