Solar PV Station Lightning Monitoring - DC SPD/Inverter/Grounding

DC-Side SPD Monitoring · Large Array Monitoring · Strike Localization

Full-element online sensing of PV array lightning protection from combiner boxes to inverters

Solar PV station lightning monitoring is a specialized solution for large dispersed arrays and DC-side lightning protection requirements, performing online monitoring of DC SPD status, inverter protection, and grounding resistance.

Industry Pain Points

Challenges

DC-side SPD mismatch: PV DC SPDs must match system voltage; wrong selection causes protection failure

Large array monitoring difficulty: PV arrays are widely dispersed; traditional inspection cannot cover all combiner boxes

Strike localization difficulty: large array areas make it hard to quickly locate damaged modules after strikes

Inverter damage risk: after inverter inlet SPD failure, lightning surges directly damage power devices

FAQ

Frequently Asked Questions

Why do solar PV stations need specialized lightning monitoring?

PV stations have special DC-side voltages and large array areas; traditional AC lightning solutions do not apply directly, requiring specialized DC SPD monitoring and large-array online monitoring.

How to select DC-side SPDs for PV systems?

DC SPDs must be selected based on PV system open-circuit voltage and maximum continuous operating voltage. The FSS smart SPD supports DC-side applications with online degradation monitoring.

How are PV array strikes localized?

Strike counts and timestamps from combiner box SPD monitors, combined with FL transient current monitoring at inverters, enable array-level strike localization and damage assessment.
