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.

Commercial Applications for the 3 String PV Combiner Box

Deploying the EKDBS-PV3/1-IFS-1000 secures vital high-voltage DC nodes, acting as a highly dependable 3 string combiner box for versatile commercial solar infrastructures.

Applications & Use Cases
