Procurement & BOM Notes
How 12 in 1 out DC 1000V Combiner Box is sourced
OmniSol sources 12 in 1 out DC 1000V Combiner Box factory-direct as part of the PV Combiner Box family, quoted against your project quantity, destination port and product family id (OS-ETK-EKDBT-PV12-1-BFS-1000). Pricing and lead time are confirmed by SKU and order size at the RFQ stage, and OmniSol can propose a current-equivalent option if the exact variant is unavailable, so the line stays on schedule.
BOM fit
12 in 1 out DC 1000V Combiner Box sits between the array and the inverter, so it is specified with the string count, system voltage and protection layout of the project. It ships consolidated with cable, connectors and the rest of the electrical BOS, under one QC report and one document set.
Certification check
Confirm the device standard, breaking capacity and any market-specific listing (IEC or UL) before ordering. OmniSol supplies the datasheet, component brand list and inspection photos.
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.
