Product Overview
Single-string 1000V DC combiner provides a weatherproof junction, disconnect, and labeling point for one PV string without the complexity of a multi-string combiner. Useful as a roof-to-ground cable transition point, an isolated string re-routing junction, or a string-level shutdown point in residential and small commercial systems.
Despite combining only one string, the IP-rated enclosure, internal fuse protection, and isolating switch provide the safe disconnection and fault protection that bare junction boxes do not.
The 1000V single-string version provides junction and fuse protection for 1000V DC system architectures used in most current-generation string inverters. String fuse rating must be at least 1.25 times string Isc — specify the fuse current rating alongside the combiner box when sending an RFQ.
Applications
PV string combining
DC array protection
C&I rooftop solar
Utility-scale field combiner circuits
Frequently Asked Questions
Why use a single-string combiner box?
A 1-in/1-out combiner provides a weatherproof, labelled, accessible junction point with fusing and isolation — not just a cable connection. It is used at roof-to-conduit transitions, string-to-monitoring connection points, or where a safe string isolation point is needed at a specific location.
What internal protection is included?
Configuration includes a string fuse and isolating switch. Confirm the required fuse current rating and whether SPD is needed at RFQ — configurations can be adjusted to project requirements.
