B-Box 2.5 bis B-Box 10.0

The BYD B-Box is a lithium-iron phosphate (LiFePO) battery unit with battery management system (BMS) for use with an external inverter or charger. Thanks to the modular construction, the B-Box is growing with its challenges:

  • B-Box 2.5 (2.5 kW / 2.45 kWh)
  • B-Box 5.0 (5.0 kW / 4.9 kWh)
  • B-Box 7.5 (7.5 kW / 7.35 kWh)
  • B-Box 10.0 (10.0 kW / 9.8 kWh)

All systems can be extended at any time with the battery modules B-Plus 2.5. In parallel connections, up to 10 kWh (9.8 kWh usable) are possible per battery cabinet. Up to 8 battery cabinets can be combined and can be expanded to 80 kWh (78.4 kWh usable).

B-Plus 2.5
  • CE and TUV certified BYD B-Plus 2.5 module (U3A1-50P-A) meets the highest safety standards
  • Proven for use in telecommunication and energy storage applications worldwide
  • Environmentally friendly, high-performance LiFePO battery technology

The B-Box 2.5 – 10.0 focuses on flexibility. The modular design allows the desired performance and capacity to be achieved as desired. The B-Plus 2.5 module is the core of the memory. Each B-Plus module is equipped with its own BMS (Battery Management System). This allows the full use of the performance even in modules of different age. The housing of the B-Box 2.5 – 10.0 is equipped with a BMU (Battery Management Unit) and can accommodate up to four of the 19 “B-Plus battery modules. A fully equipped housing (B-BOX 10.0) achieves not only 9.8 kWh usable capacity, but also a power of 10 kW. The BMU is the communication interface between the battery modules and the external inverter. The compatibility is already guaranteed to well-known inverter manufacturers, such as SMA or GoodWe, and will be further expanded. In the “Download” category you will find the current compatibility list.

Furthermore, up to eight B-boxes can be connected in parallel. This increases the maximum capacity – flexible in 2.45 kWh steps – to 78.4 kWh (usable).
No matter which inverter you use, the B-Box or the capacity you choose, the outstanding features in terms of safety and durability are guaranteed. The outstanding LFP battery technology from BYD will show its full effect. The batteries are well-tried and e.g. already permanently in use in e-mobility. Without the battery, some full electric vehicles could drive more than 800,000 kilometers. The B-Box 2.5 – 10.0 brings all the usual certifications and the possibility to KfW funding. BYD B-Box 2.5 – 10.0 offers a high-tech memory with outstanding properties at an affordable price.
