A DC SPD (Surge Protection Device) for solar PV systems is a critical safety component designed to protect solar panels, inverters, and associated equipment from electrical surges and transient voltage spikes—especially those caused by lightning strikes or switching operations.
Why DC SPDs Are Needed in Solar PV Systems?
Protection against Surges: DC SPDs shunt excess voltage to ground when a surge occurs, preventing damage to sensitive PV system components and helping avoid costly equipment failures.
Maintains System Performance: By safeguarding components, DC SPDs help ensure consistent operation and prolong the lifespan of the solar power system.
Financial and Safety Benefits:** Prevents expensive repairs and reduces the risk of fire or other safety hazards caused by voltage surges.
Voltage ratings typically range from 600VDC, 1000VDC, up to 1500VDC for utility-scale systems.
How It Works
Normal Operation: The SPD presents high resistance, allowing the PV system to operate normally.During Surges: When voltages exceed a set threshold, the SPD becomes conductive, providing a low-impedance path for the surge to ground, sparing connected equipment.Key Components: Metal Oxide Varistors (MOVs) or Gas Discharge Tubes (GDTs) are common in DC SPD's.
