Description
The Suntree DC Surge Protective Device (SPD) is an essential defense mechanism for solar energy systems, engineered to shield critical components like PV panels, inverters, charge controllers, and battery storage from damaging electrical surges. Tailored for direct current (DC) applications, it mitigates risks posed by lightning strikes, grid fluctuations, and transient voltages, ensuring uninterrupted energy production and extended equipment lifespan.
Key Features for Solar Professionals:
High Surge Handling: Max discharge current of 40kA (10/350?s) and voltage protection level (Up) as low as 2.5kV, minimizing downtime in solar arrays.
Ultra-Fast Response: Reacts in <25 nanoseconds to divert surges before they reach sensitive components.
Solar-Optimized Design: Compatible with DC systems up to 1500V, ideal for large-scale solar farms, rooftop installations, and off-grid setups.
Durable Construction: Flame-retardant (UL94 V-0), IP65-rated enclosure for dust/water resistance, and corrosion-resistant terminals for harsh outdoor or industrial environments.
Status Monitoring: Visual indicators (LED) and remote signaling contacts (dry contact) for real-time surge tracking and maintenance alerts.
Compliance: Certified to IEC 61643-31, T?V Rheinland, and RoHS standards, meeting global solar safety requirements.
Applications:
Protection of solar PV strings, combiner boxes, and DC distribution panels.
Integration with inverters (SMA, Huawei, etc.), battery banks, and charge controllers.
Ground-mounted solar farms, commercial rooftops, and hybrid renewable energy systems.
Installation & Supply Advantages:
Easy Mounting: DIN rail-compatible design for quick integration into existing solar enclosures or switchgear.
Plug-and-Play: Pre-wired terminals and color-coded wiring diagrams streamline installation.
Bulk Availability: Stocked in multiple configurations (2P, 3P) and customizable voltage ratings for project scalability.
Global Logistics: Reliable supply chain with competitive MOQs and fast delivery to solar contractors and distributors.
