BYD B-Box Premium HV power supply module for HVS or HVM

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 real high-voltage series connection.
• The patented modular plug design requires no internal wiring, providing maximum flexibility and ease of use.
• Cobalt-free lithium iron phosphate (LFP) battery: Maximum safety, life 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 consists of 2 to 5 HVS battery modules 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. Battery-Box Premium HVS enables a maximum capacity of 38.4 kWh. Possibility to scale up by adding HVS modules or parallel HVS stacks later.

A Battery-Box Premium HVM consists of 3 to 8 HVM battery modules 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. Possibility of scaling up 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 capacity of 5.1 kWh. The HVS is expandable to a maximum of 5 modules. This gives you a total capacity 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 - which achieves a maximum capacity of 38.4 kWh.

The BYD HVM battery, or High-Voltage Medium, is larger in terms of 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 for 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 - which achieves a maximum capacity of 66.2 kWh.
