Combiner Manual Introduction

Introduction
SMA America has introduced a new line of PV combiner boxes designed for use with the SMA
family of inverters.
Combiner Box features include:
• Listed to UL 1741 for the United States and Canada
• Simplified input and output wiring
• Compact, low-cost design
• Wall-mount NEMA type 3R outdoor steel enclosure (NEMA type 4 available for SCCB-12,
SCCB-28).
• Reliable bus-work for combined high current conductors
Unpacking and Inspection
All SMA Combiner Boxes are thoroughly checked before they are packaged and shipped.
Although they are shipped in sturdy packaging, damage can still occur during shipping and
delivery. It is important to carefully inspect the shipping container and contents prior to
installation. If you detect any external damage after unpacking, report the damage immediately to
your SMA dealer and shipping company that delivered the unit. If it becomes necessary to return
the Combiner, use the original packing material.
If you need assistance in dealing with a damaged unit, contact SMA America at 916 625 0870.
Input Circuit Configurations
The SBCB and SCCB Combiner Boxes are commonly available with 6, 12, 28 or 52 PV input
circuits. Other sizes in between 6 and 52 circuits may be special ordered. Please allow sufficient
lead time when custom ordering. Contact SMA America for details.
