BYD HVM 2.76kWh high-voltage battery module, modular

The HVM 2.76 kWh high-voltage battery module from BYD impresses with its high cycle stability and remarkable durability thanks to its LiFePO4 technology. The modular and stackable design of the battery allows for versatile use in various scenarios and is characterized by its very straightforward installation. It offers outstanding performance, even under high loads. In addition to the battery management system and the base, the battery is the main indicator of the BYD HVM Battery Box Premium. This storage system can be easily expanded from 3 to 8 modules in series without cables. The parallel connection of up to 3 identical battery boxes also enables a maximum capacity of 66.2 kWh.

The new system generation

The new BYD generation is based on the proven storage systems and offers all the previous functions. The Battery-Box Premium HVM brings a battery module to the market that has a higher storage capacity than its predecessor. Thanks to advances in cell technology, the system weight has been reduced by almost 30% and the depth by 8 cm, which requires less space and results in a sleeker appearance. A highlight of the new storage units is their IP55 protection class, which allows them to be used outdoors. In addition, the new generation offers even greater flexibility and scalability. Up to three battery towers can now be connected to form a single system. BYD remains true to its line in terms of charging and discharging performance, as each battery can also deliver its rated capacity as power, i.e., 1C. This makes the new series ideal for on-grid, on-grid plus backup, and off-grid systems.

Modular battery system

The HVM Battery Box can be configured with 3 to 8 HVM battery modules arranged in series. This allows a capacity of 8.3 to 22.1kWh to be achieved. To achieve the maximum capacity of 66.2 kWh, up to 3 identical HVM towers can be connected directly in parallel. It is also possible to expand the system later by adding additional HVM modules or parallel HVM towers.

Power supply at all times: BYD backup power and off-grid function

The B-Box HVM is extremely versatile and can be used in both on-grid and off-grid systems. Its integrated emergency power function is particularly practical and often in demand. This enables the B-Box to supply the entire household with power in the event of a power failure, either on one or three phases. The prerequisite for this is a compatible hybrid or storage inverter that supports both an emergency power and an off-grid function. A list of compatible inverters can be found in the "Downloads" section.

Power and storage capacity: Scalability made easy

BYD attaches great importance to the scalability of its storage systems. The new B-Box HVM is easy to retrofit and allows for simple expansion. A simple plug connection eliminates cable clutter and unnecessary complexity in product design. It is possible to add additional storage modules. Furthermore, by connecting up to three storage towers in parallel, a maximum storage capacity of 66.2kWh and a discharge power of 66.2kW can be achieved. It is important to note that each storage tower must have the same number of modules.
