SPD INTRODUCTION / SPD IN PHOTOVOLTAIC INSTALLATIONS (ONLINE)

Hosted by ElectroMechanica and ECA(SA)

Presented by Enrique Tornell (Barcelona) via Zoom Free of Charge (REGISTRATION LINK BELOW)

📅 Training Schedule

• 🔹 AC Session 🗓 Wednesday, 16 September 2026 🕙 10:00 – 12:00 📍 Online (Zoom)
• 🔹 DC Session 🗓 Monday, 21 September 2026 🕙 10:00 – 12:00 📍 Online (Zoom)

🎯 Objectives

• AC Session: Refresh the basics behind SPDs and guide participants into the most challenging topic — SPD backup protection. Introduce the new SSD (SPD Specific Disconnector) and demonstrate how CIRPROTEC SPD ranges simplify selectivity for installers and board manufacturers.
• DC Session: Apply IEC standards to PV DC SPDs, explain why surge protection is critical in photovoltaic installations, detail installation types, and provide selectivity guidance. Conclude with SPD backup fuse requirements for PV DC SPDs.
