Yaskawa Solectria CR1500-20P-32F-250S Output Fused Remote String Combiner

Yaskawa Solectria 1500VDC Output Fused Remote PV String Combiner Box (CR1500-20P-32F-250S)

The Yaskawa Solectria CR1500-20P-32F-250S is a commercial and utility-grade 1500 VDC remote solar PV string combiner box engineered to consolidate up to 20 solar panel string inputs into a single high-capacity DC output line. Built into a polyester powder-coated steel NEMA Type 4 outdoor enclosure, this unit provides array-level DC circuit consolidation, overcurrent protection, and rapid manual disconnect capability for centralized solar installations.

Designed for positive polarity fusion, the unit comes pre-populated with high-capacity 32A fuses across all 20 input positions. Key equipment features include an externally operable 250A 2-pole DC disconnect switch and integrated DC surge protection to shield connected string circuits and inverter electronics against transient voltage spikes in demanding outdoor array environments.
