With BYD's HV Premium Combiner Box, up to three storage units from the HVS and HVM series can be connected in parallel quickly and efficiently. Due to parallel connection, the towers must have the same voltage level (number of batteries) and charge level. This is especially important when expanding storage capacity. Additionally, the connection cables from the towers to the Combiner Box should be of equal length. The planned configuration should be checked for approval in BYD’s "Premium HV Compatible Inverter List."

Please note: as before, HVS, HVM, and older HV systems cannot be combined with each other.
