3 MPPT Solar Protections Kit 600V 50A Aurensol

Product Description

The Kit Protections 3 MPPT Solar 600V 50A Aurensol brings together in a single weatherproof enclosure all the necessary direct current protections for three photovoltaic strings that feed three independent MPPT inputs. Each branch has its own 600 V DC type 2 surge protection device (SPD) and a 2P 50 A 800 VDC curve C photovoltaic circuit breaker, ensuring safe DC disconnection, real selectivity per string, and service continuity. The 18-module IP65 enclosure offers clean DIN rail mounting, clear labeling, and space reserved for additional disconnection or instrumentation, speeding up commissioning and reducing selection errors.

Main Features

• Polycarbonate enclosure IP65, 18 modules (1 row), suitable for indoor or protected outdoor use.
• 3 × SPD DC 600 V 2P Type 2 with replaceable cartridge, one for each string/MPPT.
• 3 × PV circuit breaker 2P 50 A 800 VDC curve C with specific DC breaking capacity.
• String topology: selective tripping, fast diagnosis, and enhanced safety.
• DIN rail architecture with space for disconnectors, gPV fuses, or measurement devices.

Advantages or Benefits

• Coordinated protection that limits damage to modules, connectors, and inverter electronics.
• Greater availability: events in one branch do not affect the rest of the strings.
• Quick and maintainable installation thanks to organized wiring and easy access to terminals.
• Prepared for high-current TOPCon/bifacial modules and MPPT up to 600 VDC.
• Professional assembly that reduces engineering, procurement, and installation times.

Purpose or Applications

Ideal for advanced residential self-consumption and small commercial rooftops with three orientations or differentiated fields, when the current per string reaches ≤50 A and the generator voltage is ≤600 VDC.
