Product Features of the 24 String Combiner Box

Constructed to manage unprecedented power densities, this 24 String Combiner Box replaces standard switching with heavy MCCB isolation within a robust metal housing.

Ultra-High Density Aggregation: Seamlessly consolidates 24 independent PV strings into a single massive output, optimizing your 24 string combiner box setup for utility-grade energy harvesting.
Heavy-Duty MCCB Protection: Features a rugged 1000V/250A DC Molded Case Circuit Breaker (2-Pole) to actively interrupt severe overcurrents (15kA Icu) and securely isolate the entire array.
Premium Surge Defense: Integrates a Type 2 40kA DC surge protective device (SPD) to instantly suppress damaging electrical transients before they reach central inverters.
Individual String Isolation: Houses forty-eight 10A (10x38mm) DC fuse links to securely protect both positive and negative lines of each string directly at the solar source.
Industrial Metal Architecture: The highly durable metal enclosure delivers exceptional IK10 impact resistance and strict IP65 protection against intense UV rays, dust, and rain.

Commercial Applications for the 24 String Combiner Box

Deploying the EKDBT-PV24/1-1000 secures massive DC power outputs, functioning as a highly resilient 24 string combiner box for critical industrial infrastructures.

Applications & Use Cases

Utility-Scale Solar Farms: Protects and merges extreme power loads from extensive ground-mounted arrays exposed to severe environmental degradation.
Massive Commercial Rooftops: Consolidates unparalleled array capacities while ensuring MCCB-level protection for high-voltage central inverters.
Industrial Microgrids: Ideal for complex distributed systems requiring robust, centralized aggregation and rapid, high-capacity circuit breaking.
