SUP2H-PV Series Surge Protector

The SUP2H-PV Series Surge Protector is a high-efficiency DC surge protection device engineered for modern photovoltaic (PV) systems. It provides reliable protection against transient overvoltage events caused by lightning strikes, switching operations, grid disturbances, and environmental factors that threaten sensitive solar components. Designed for both string-level and array-level protection, this SPD is essential for maintaining system stability, safety, and long-term performance.

Solar installations—especially rooftop systems, ground-mounted arrays, and solar farms—are highly exposed to external conditions that increase the risk of electrical surges. The SUP2H-PV Series is built with advanced Metal Oxide Varistor (MOV) and gas discharge tube (GDT) technology, offering rapid surge response and high discharge capacity. This ensures that dangerous voltage spikes are diverted safely to earth, preventing damage to inverters, charge controllers, PV modules, and DC wiring.

Its modular cartridge design allows quick, tool-free replacement of protective modules, enabling fast maintenance without system downtime. The SPD includes a clear visual status window, providing instant indication of protection status. If a module becomes faulty, it can be replaced immediately, ensuring continuous system reliability.

Engineered with a fire-resistant and UV-protected housing, the SUP2H-PV Series performs exceptionally well even in harsh outdoor conditions. It complies with international standards such as IEC 61643 for surge protective devices, ensuring compatibility with solar installations worldwide.

This surge protector is available in multiple voltage ratings—typically 600V, 1000V, and 1500V DC—making it suitable for residential, commercial, and utility-scale solar systems. Its compact design allows easy integration into PV combiner boxes, inverter input protection systems, battery banks, and DC distribution panels.

Additional protective features include overheating protection, internal safety disconnect mechanisms, and arc suppression technology, all of which contribute to safer solar operation. Whether you are building a new PV system or upgrading an existing one, the SUP2H-PV Series Surge Protector ensures maximum uptime, equipment longevity, and superior system protection.
