BYD B-Box Premium HVS/HVM Combiner Box - CBH-40A

Overview

The BYD Battery-Box Premium HVS/HVM Combiner Box is designed exclusively for use with BYD Battery-Box Premium HVS or HVM battery systems. It enables the parallel connection of 2 or 3 battery towers, providing a streamlined and secure solution for DC cabling in larger energy storage installations.

The combiner box simplifies system design by consolidating multiple battery towers into a single DC cable connection to the inverter. All connected towers must use the same battery type (HVS or HVM), have identical module quantities, and be installed with matching state of charge (SOC).
