B-Box Premium HV Combiner Box HVS/HVM/HVB

With the HV Premium Combiner Box from BYD, up to 3 storage units of the HVS and HVM series can be connected quickly and efficiently. Due to the parallel connection, the towers must have the same voltage (number of batteries) and charge level. This is especially important for storage extensions. In addition, the connection cables from the towers to the combiner box must be of the same length. The planned configuration must be checked for approval in BYD's "Premium HV Compatible Inverter List". As before, HVS, HVM and older HV systems cannot be combined with each other.
