BYD B-Box Premium HV Battery Control Unit + Base, 2-5x HVS or 3-8x HVM.

• Suitable for high-power emergency backup and off-grid functionality

• Highest efficiency thanks to a true high-voltage series connection

• The patented modular plug design requires no internal wiring and ensures maximum flexibility and ease of use

• Cobalt-free lithium iron phosphate (LFP) battery: Maximum safety, lifespan and power

• Compatible with leading 1 and 3 phase high voltage battery inverters

• Two different modules for a full range of system sizes

• Highest safety standards such as VDE 2510-50

A Battery-Box Premium HVS is composed of 2 to 5 HVS battery modules that are connected in series to achieve a usable capacity of 5.1 to 12.8 kWh. In addition, direct parallel connection of up to 3 identical devices is possible. Battery-Box Premium HVS enables a maximum capacity of 38.4 kWh. Ability to scale up by adding HVS modules or parallel HVS stacks later.

A Battery-Box Premium HVM is composed of 3 to 8 HVM battery modules that are connected in series to achieve a usable capacity of 8.3 to 22.1 kWh. In addition, direct parallel connection of up to 3 identical Battery-Box Premium HVM enables a maximum capacity of 66.2 kWh. Ability to scale by adding HVM modules or parallel HVM stacks later.

The BYD battery from the HVS series, which stands for High-Voltage Small, has the smallest capacity, as the name suggests. A standard package consists of 2 battery modules with a combined power of 5.1 kWh. The HVS is expandable to a maximum of 5 modules. This gives you a total power of 12.8 kWh. Each individual module has a capacity of 2.56 kWh with an internal voltage of 102.4V. Whether you can use a total of 5 modules depends on the battery or hybrid inverter that is used. You can connect a maximum of 3 battery towers in parallel - so 3 x 5 battery modules - reaching a maximum power of 38.4 kWh.

The BYD HVM battery, or the High-Voltage Medium, has greater power than the HVS. A basic package consists of 3 battery modules with a combined capacity of 8.3 kWh. This model can be expanded to a maximum of 8 modules with a combined capacity of 22.1 kWh. Each module has a capacity of 2.76 kWh and an internal voltage of 51.2V.

There is also a minimum with this model. You must use at least 3 modules for a functioning battery. A maximum of 3 identical systems can be connected in parallel - so 3 x 8 - reaching a maximum power of 66.2 kWh.
