Product Overview
Twelve-string 1000V DC combiner with fuse protection per string and a single output for mid-scale commercial installations and ground-mount projects where 12 strings feed one inverter MPPT input. The BFS (box with fuse and switch) configuration includes per-string fuse protection and a combined output isolating switch.
A 12-string combiner at 12A Isc per string produces approximately 144A combined output — confirm the output current against the DC cable and downstream MCCB rating before ordering.
Twelve-string combiner is a standard unit for 100–200kW central inverter sub-arrays. Mount with cable glands positioned downward to prevent water ingress through top cable entries — confirm enclosure orientation with the installation contractor during the mechanical design review, as combiner mounting position affects conduit routing.
Applications
PV string combining
DC array protection
C&I rooftop solar
Utility-scale field combiner circuits
Frequently Asked Questions
What is included in the BFS configuration?
BFS (box with fuse and switch) includes per-string gPV fuse protection and an output isolating switch or main DC MCCB at the combiner output. Wiring diagrams and fuse current ratings should be confirmed against string Isc values at RFQ.
What is the IP rating for outdoor installation?
Confirm the enclosure IP rating from the product datasheet — combiner boxes for outdoor installation should be IP54 minimum. Share the installation environment (rooftop, ground-mount, desert) at RFQ and we confirm the appropriate IP rating.
