⚡ Key Benefits
🔐 Solar Solar Protection System Against Overvoltages

✔️ Integrated DC surge protection (DC-SPD) protects the DC side of the PV system from overvoltages, e.g., caused by lightning strikes or grid transients – a common cause of damage in PV systems.

✔️ Three-stage switching/short-circuit device ensures safe disconnection in the event of a fault.

🏠 IP65 Protection – For Indoor and Outdoor Use

✔️ Robust IP65 housing protects against dust and water jets, making it suitable for installation on facades, roof slopes, or in technical rooms without an additional protective wall.

✔️ Impact resistance (IK08) ensures high mechanical robustness.

🔧 Compliant with Standards & Norms

✔️ Designed according to DIN EN IEC 61439-2 and IEC 60364-7-712 for PV applications – essential for standards-compliant electrical installations.

✔️ Compact design with push-in or screw terminals simplifies installation and maintenance.

🔌 Flexibility for String Configurations

✔️ Protects two independent MPPT inputs, each with its own string – ideal for inverters with two MPPT tracker inputs.

✔️ Connection options for large cable cross-sections via M20 glands.

🛠️ Safety & Reliability

✔️ Short-circuit withstand capability up to 10 kA (ISCPV) and surge currents (8/20 µs) up to 40 kA ensure reliable protection against high voltage surges.

✔️ Fault indication enables rapid diagnosis and maintenance.
