Product Overview
The BYD Battery-Box Premium HVM 2.76kWh Battery Module is the modular building block used to expand or configure a BYD Battery-Box Premium HVM high-voltage battery system. Each HVM module provides 2.76kWh of battery capacity at 51.2V and uses cobalt-free Lithium Iron Phosphate (LFP) cell technology for high safety, long service life and strong power performance.
A complete BYD Battery-Box Premium HVM system requires multiple HVM battery modules connected in series together with the appropriate BYD Battery Control Unit (BCU) and base. A single HVM module is not designed to operate as a standalone battery.
Key Features
-
2.76kWh modular capacity: Each HVM module contributes 2.76kWh to the overall battery system.
-
51.2V nominal module voltage: Designed specifically for the high-voltage BYD Battery-Box Premium HVM platform.
-
Flexible system sizing: HVM systems are assembled using 3 to 8 HVM modules per battery tower, providing usable system capacities from 8.28kWh to 22.08kWh.
-
Expandable architecture: HVM battery systems can be expanded by adding modules, subject to BYD installation and compatibility requirements.
-
LFP battery chemistry: Cobalt-free Lithium Iron Phosphate technology provides excellent thermal stability, safety and cycle life.
-
High-voltage series connection: Designed for efficient high-voltage operation with compatible single- and three-phase battery inverters.
-
Plug-in modular design: BYD's patented internal connection system reduces internal wiring requirements and simplifies installation.
-
Backup and off-grid capable: Suitable for compatible on-grid, backup and off-grid energy storage systems.

Important Compatibility Information
- This listing is for one BYD Battery-Box Premium HVM 2.76kWh battery module.
- The module cannot be used as a standalone 51.2V battery.
- A complete HVM battery tower requires a minimum of 3 HVM modules together with the compatible BYD Battery Control Unit (BCU) and base.
- HVM modules are intended for use only within the BYD Battery-Box Premium HVM platform and should not be mixed with HVS modules.
- Always confirm inverter compatibility against the current BYD Battery-Box Premium compatible inverter list before installation.
- System usable energy and operating performance may vary depending on the inverter, operating conditions and installation configuration.
