The BYD Battery-Box Premium HV Combiner Box is a combiner box unit designed for the parallel connection of two or three BYD Battery-Box Premium HVS or HVM battery towers. It is an essential accessory for creating larger high voltage (HV) storage systems, allowing simple, safe, and reliable DC cable connection between multiple batteries.

The device ensures uniform operation and charging of all towers, provided that the BYD Premium HV Compatible Inverter List guidelines are followed and towers with the same number of modules and the same state of charge are used during installation.
