BYD Battery-Box HVM+ High-voltage battery storage

The BYD Battery-Box HVM+ is a modular high-voltage battery system based on lithium iron phosphate (LiFePO4) cells. Designed for grid-connected, backup, and off-grid applications, it offers maximum safety, efficiency, and flexibility. The system's modular design allows for expansion and the addition of new components at any state of charge (SoC).

Important NOTE

The HVM+ system is not compatible with previous HVM systems.
It can only be used with HVM+ battery modules and the BYD Battery-Box Premium BCU for HVB/HVS+/HVM+.
