BYD Battery Box Premium HVS / HVM

The BYD Battery-Box Premium HVS and HVM are modular high-voltage batteries based on lithium iron phosphate (LFP), designed for use with an external inverter. These systems are highly scalable, safe, and among the most efficient solutions on the market for residential and commercial energy storage.

Battery-Box Premium HVS

A Battery-Box Premium HVS consists of 2 to 5 HVS battery modules, combined with a BCU (Battery Control Unit) and a base. The modules are connected in series, resulting in a usable capacity of 5.1 to 12.8 kWh*.

By connecting up to 3 identical HVS systems in parallel, the total storage capacity can be expanded to 38.4 kWh*.

Battery-Box Premium HVM

A Battery-Box Premium HVM consists of 3 to 8 HVM battery modules, also supplemented with a BCU and base, which are connected in series. This provides a usable capacity of 8.3 to 22.1 kWh*.

Like HVS, HVM can also be expanded by connecting up to 3 identical systems in parallel, allowing for a maximum capacity of 66.2 kWh*.
