SUP2H1-PV Series Surge Protector

SUP2H1-PV Series Surge Protector is a device specifically designed to protect photovoltaic (PV) solar power systems from overvoltage surges caused by lightning strikes or switching operations. These surge protective devices (SPDs) are critical for ensuring the safety and longevity of solar installations by safeguarding the solar panels, inverters, and other sensitive components.

Features of SUP2H1-PV Series Surge Protector:

1. DC Surge Protection for Solar PV Systems: The SUP2H1-PV series is designed for DC circuits, making it ideal for solar PV applications where DC voltage protection is required.
2. High Voltage Rating: Typically, these surge protectors are available in different voltage ratings suitable for various PV system configurations, such as 600V DC, 1000V DC, and up to 1500V DC. This allows them to be used in small residential systems to large commercial and utility-scale solar installations.
3. Type 1+2 SPD: The SUP2H1-PV series usually complies with Type 1+2 classifications according to IEC 61643-11. This means they provide both primary and secondary protection, suitable for direct and indirect lightning strikes as well as switching surges.
4. High Discharge Capacity (Imax): The SPD is capable of handling high surge currents, often up to 40kA or higher, ensuring robust protection against severe surges.
5. Plug-In Module Design: The modular design allows for easy replacement of damaged modules without removing the entire SPD base, reducing maintenance time and costs.
6. Thermal Disconnect Mechanism: Equipped with an internal thermal disconnect feature that safely isolates the surge protection module from the system in the event of an overload or failure, preventing fire or damage.
7. Remote Signaling Contact (Optional): Some models come with an optional remote signaling contact that allows monitoring of the SPD status. This feature is beneficial for integration into remote monitoring systems, ensuring timely maintenance and replacement.
8. Visual Status Indicator: Each module has a visual indicator (usually green/red) to show the operating status. Green typically indicates normal operation, while red signals a failure or that replacement is needed.
9. DIN Rail Mounting: The device is designed for easy installation on standard 35mm DIN rails, making it compatible with most electrical enclosures and panels.
10. UV and Weather Resistance: The enclosure and components are designed to withstand outdoor conditions, ensuring reliable operation even in harsh environments.
11. Compliance with International Standards: Meets IEC 61643-31 standards, ensuring safety, reliability, and performance in protecting solar PV systems.

Benefits:

• Enhanced Protection for Solar Systems: Safeguards sensitive equipment like solar panels, inverters, and controllers from overvoltage surges.
• Reduces Downtime and Maintenance Costs: The modular design allows for quick and easy replacement of surge protection modules.
• Ensures System Longevity: Prevents potential damage to PV components, increasing the overall reliability and lifespan of the solar power system.
• Easy Monitoring: Visual indicators and optional remote signaling provide straightforward monitoring and management of the SPD’s health.
• Flexible Installation: Compatible with a variety of PV system voltages and configurations.
