The BYD B-Box HV Premium Combiner Box HVS/HVM enables the parallel connection of up to three compatible battery storage units from the BYD HVS and HVM series. This allows the total capacity of the storage system to be expanded flexibly.
For operation, all connected battery towers must have the same voltage range and a comparable state of charge. Furthermore, it must be ensured that the connection cables between the storage towers and the combiner box are of identical length.
A combination of different system generations is not possible. HVS, HVM, and older BYD HV storage systems must therefore not be operated together via the combiner box.
