COMBINER BOXES

Introducing SMA America’s SCCB Combiner Boxes. The SCCB combiners are available in sizes ranging from 6 to 52 PV inputs to provide greater flexability and expandability in system design. Oversized bus-work adds high efficiency and dependability where it’s needed most. The large NEMA 3R/4 enclosure provides ample room for conductors which reduces installation time. Designed with installers in mind, we know you’ll find the new SCCB Combiner Boxes a welcome addition to our great line of inverter products.
