Sungrow PowerKeeper Battery Junction Box
SKU: SJC160-02
The Sungrow PowerKeeper Battery Junction Box (SKU: SJC160-02) is an essential power distribution and circuit protection unit designed for multi-battery commercial and industrial (C and I) energy storage configurations. Functioning as a high-voltage DC combiner box, it enables seamless multi-battery system cascading—allowing 4H, 6H, or 8H energy storage configurations to parallel safely into a single hybrid inverter. Equipped with a built-in main load switch, dedicated DC input/output terminals, and a protective wiring cover, the SJC160-02 simplifies multi-stack wiring while ensuring high electrical safety and circuit isolation across complex commercial storage systems.
