SUP2H1-PV Series Surge Protector

The SUP2H1-PV Series Surge Protector is a high-performance DC surge protection device designed specifically for photovoltaic (PV) solar power systems. Engineered to safeguard solar installations against transient overvoltages caused by lightning strikes, switching operations, and grid disturbances, this SPD ensures long-term system reliability and protects sensitive components such as inverters, charge controllers, and DC wiring.

Solar PV systems are highly exposed to outdoor environments, making them vulnerable to surges that can significantly damage equipment or reduce system performance. The SUP2H1-PV Series provides an essential defense by diverting sudden voltage spikes safely to ground, preventing dangerous overloads and prolonging the lifespan of your solar equipment. It is suitable for use in solar combiner boxes, inverter DC input terminals, and off-grid DC distribution systems.

This surge protector is built with high-quality MOV (Metal Oxide Varistor) and gas discharge tube technology, offering fast response time and high surge-handling capacity. Its modular design allows easy replacement of SPD modules without disconnecting the entire system, reducing downtime during maintenance. A visual status indicator provides quick identification of protective module condition, ensuring installers can easily detect and replace faulty units.

The SUP2H1-PV Series Surge Protector is crafted using flame-retardant, UV-resistant, and durable housing materials, making it suitable for harsh outdoor conditions. It complies with global standards for surge protection, ensuring safe operation and compatibility with a wide range of solar systems.

This SPD is available in various voltage ratings to match different PV system configurations, including 600V, 1000V, and 1500V options. Its compact size makes installation simple while maximizing space efficiency within PV combiner boxes and enclosures. With strong thermal protection, internal safety shutoff mechanisms, and high discharge current ratings, the SUP2H1-PV guarantees stable and safe performance even in lightning-prone regions.

Whether used in residential, commercial, or utility-scale installations, the SUP2H1-PV Series Surge Protector ensures uninterrupted solar energy production, reduces costly downtime, and enhances the overall reliability of your PV power system.
