The BYD Battery-Box LV Flex is a lithium iron phosphate (LFP) battery pack for use with an external inverter. The communication with the inverter is established through the Battery-Box Premium LV BMU (Battery Management Unit). Connect up to 64 LV Flex Modules in parallel on one BMU to reach individual capacities between 5 and 320 kWh. Thanks to it´s 3U design, the LV Flex can adapt to off-the-shelf racking systems. And with the possibility of stacking up to 4 units or installing them vertically, the LV Flex provides a variety of options for bespoke housing designs.

The BYD B-Box Premium LVL has powerful on-grid, backup and off-grid functions for private and commercial applications.

The new battery storage also has protection rating IP20. This means that the BYD B-Box Premium LVL 15.4 can only be used indoors.

Flexible and Scalable

In total, up to 64 B-Box Premium LVL 15.4 can be connected in parallel to achieve a total capacity of 983.04 kWh.

The BYD Battery-Box Premium LVL 15.4 is compatible with the market leading 1- and 3-phase inverters from GoodWe, Victron and SMA (Sunny Island).

Advantages of the BYD B-Box Premium

• All models of the Battery-Box Premium series comply with the VDE 2510 safety standard and have additional safety functions for installation.
• The systems support parallel connections without the need for additional communication devices.
• They are more flexible and scalable and cover a wider range of applications.
• The new cobalt-free premium generation also features a higher energy density and a more compact format, thus requiring less floor space.
• The higher capacity per module reduces the number of components. In combination with the improved design and a new locking mechanism, this should make installation easier and reduce installation time.
• Lithium Iron Phosphate Battery (LFP): Maximum safety, lifetime and performance
• In addition to a new LED status display, there is also a new interface and the option of remote control.
