Product Features of the 3 String PV Combiner Box
Constructed for rigorous outdoor commercial solar installations, this 3 String PV Combiner Box integrates premium surge protection and independent DC isolation within a rugged polycarbonate housing.
- Triple-String Integration: Efficiently merges three separate high-voltage PV arrays into a single 30A output, streamlining your 3 string combiner box configuration and minimizing site wiring complexity.
- Advanced Surge Protection: Equipped with a Type 2 40kA DC surge protective device (SPD) to instantly suppress damaging voltage spikes and safeguard downstream grid-tied inverters.
- Reliable DC Isolation: Features a dedicated 600V/32A DC isolator switch (4-Pole) for safe, rapid, and complete circuit disconnection during vital maintenance operations.
- Individual String Protection: Includes six 10A (10x38mm) DC fuses to safely interrupt catastrophic overcurrents directly at the solar source for each independent string.
- Weatherproof Architecture: The durable PC enclosure carries a strict IP65 protection degree and an IK08 impact rating for long-term outdoor resilience against severe dust and rain.
