BYD Battery Box Premium HVM/HVS Battery Base and Control Unit 2.0

An HVS stack contains 2–5 modules wired in series, delivering 5.1 – 12.8 kWh of usable energy.

Up to three identical HVS stacks can be paralleled, expanding storage to 38.4 kWh.

Systems are field-upgradeable: simply add extra HVS modules or parallel stacks when capacity needs grow.

Battery-Box Premium HVM

Each HVM stack combines 3–8 series-connected modules for a usable capacity of 8.3 – 22.1 kWh.

As with HVS, you can parallel three matching HVM stacks to reach a total of 66.2 kWh.

Additional HVM modules or stacks can be incorporated later for seamless scaling.
