Common questions from solar EPCs + utility-scale developers + rooftop solar integrators sourcing Citel solar PV DC SPDs through Vasundhara.
Solar PV arrays are large-area copper-wired installations exposed to direct + indirect lightning strikes. A single lightning event can induce thousands of volts on the DC array wiring + string-combiner outputs + inverter DC inputs — destroying expensive solar inverters (₹3-15 lakh+ per inverter on utility-scale plants) + damaging strings of solar panels. DC SPDs at the string-combiner level + inverter-input level discharge these surges safely to earth before they damage equipment. Per IEC 60364-7-712 + IEC 62305: SPD installation is mandatory for PV systems >3 kW + recommended for all installations.
Match the SPD voltage rating to the maximum DC array voltage of the installation: 600 V DC SPDs for older / smaller installations + residential rooftop typically operating at 600 V DC; 1000 V DC SPDs for most modern utility-scale + commercial rooftop installations operating at 1000 V DC array voltage; 1500 V DC SPDs for newer utility-scale solar plants designed for 1500 V DC operation (higher BOS efficiency). Verify the maximum array voltage per the panel specification + string-design + temperature-correction calculation. SPD rating must be ≥ maximum DC array voltage at minimum-temperature open-circuit condition.
Standard DC SPD installation per IEC 60364-7-712: (1) at the string combiner box DC output (one SPD per string-combiner) — protects multiple strings + the DC cable run from combiner to inverter; (2) at the inverter DC input (one SPD per MPPT input) — protects the inverter electronics from surges arriving on the DC cable run. For larger installations: also at long-cable-run intermediate points if the cable run between combiner + inverter exceeds ~30 m. For installations with external LPS: Type 1+2 combined SPDs at the array entrance into the building / inverter room.
Yes. Citel's DS50PV DC SPD range (Type 2 + Type 1+2 combined, 600 / 1000 / 1500 V DC variants) is fully compliant with IEC 61643-31 / EN 61643-31 + IEC 60364-7-712 photovoltaic system electrical installation requirements. Per-shipment IEC 61643-31 type-test certificates + CE marking provided. Suitable for utility-scale solar EPC documentation + rooftop solar installation compliance + state-utility solar power purchase agreement (PPA) compliance audit.
Per IEC 60364-7-712 + Citel datasheet: DC SPD backup-protection fuse should be gPV-class (specifically rated for PV applications, with DC interrupting capability) sized at 1-1.25× the maximum design current of the protected string. For string-combiner-level SPDs: typical 16 A / 25 A gPV fuses. For inverter-input SPDs: per the inverter manufacturer's specification. DC isolator selection: maximum operating voltage ≥ array voltage + DC interrupting capability. Vasundhara provides DC SPD coordination engineering support including backup-protection sizing for projects where we are the supply partner.
IEC 60364-7-712 makes DC SPDs mandatory for PV systems >3 kW capacity. Most residential rooftop installations exceed this threshold + typically benefit from DC SPD installation regardless of code requirement — solar-inverter cost (₹50,000+) is much higher than the DC SPD cost (₹5,000-10,000) + lightning damage to a residential inverter is uninsured loss. State-utility solar interconnection requirements increasingly specify DC SPD installation as part of the net-metering approval. Best practice: install DS50PV-600 DC Type 2 SPD at the inverter DC input for all residential rooftop solar installations.
