Product Features of the 4 String PV Combiner Box

Engineered for industrial high-capacity configurations, this 4 String PV Combiner Box replaces standard isolators with advanced MCB protection for maximum safety.

  • High-Current Aggregation: Efficiently routes four distinct PV arrays into a single powerful output, transforming your pv combiner box 4 string setup for heavy commercial loads.
  • Advanced MCB Protection: Features a heavy-duty 1000V/63A DC Miniature Circuit Breaker (4-Pole) to actively interrupt severe overcurrents and isolate the circuit.
  • Premium Surge Defense: Integrates a Type 2 40kA DC surge protective device (SPD) to instantly suppress damaging electrical transients and protect downstream inverters.
  • Individual String Isolation: Houses eight 15A (10x38mm) DC fuse links to securely protect the positive and negative lines of each string directly at the solar source.
  • Weatherproof Architecture: The impact-resistant IK08 polycarbonate enclosure delivers strict IP65 protection against intense UV rays, dust, and rain.

Commercial Applications for the 4 String PV Combiner Box

Deploying the EKDBS-PV4/1-FBS-1000 secures massive DC power outputs, functioning as a highly resilient 4 string combiner box for industrial solar infrastructures.

Applications & Use Cases
