BYD Battery-Box Premium HVM 2.76 kWh is one lithium iron phosphate battery module for the original modular high-voltage HVM platform. It is intended for a correctly matched residential photovoltaic storage tower and is not a complete battery system on its own.

One original HVM module, not HVM+ or BCU2.0

This item contains one original-generation HVM battery module. A working tower requires three to eight compatible original HVM modules, the matching original-generation BCU and base, an inverter approved for the exact configuration, electrical protection and professional commissioning. The later HVM+ / BCU2.0 generation is a separate product family and must not be substituted without written compatibility confirmation for the exact project.

Verified module and tower data

• Module usable energy: 2.76 kWh
• Module nominal voltage: 51.2 V DC
• Cell chemistry: lithium iron phosphate (LiFePO4 / LFP)
• Module weight: 35 or 38 kg, depending on the manufacturer-documented cell version
• Tower configuration: 3 to 8 compatible HVM modules
• Tower usable energy: 8.28 to 22.08 kWh
• Tower nominal voltage: 153.6 to 409.6 V
• Tower operating voltage: 120 to 472 V, depending on configuration
• Maximum output current: 50 A; peak 75 A for 3 seconds
• Communication: CAN / RS485

Efficiency, environment and installation

The complete correctly assembled system is specified for at least 96% round-trip efficiency, IP55 protection, indoor or outdoor floor-standing use and -10 °C to +50 °C operation. Output is derated between -10 °C and +5 °C. Outdoor suitability does not remove the requirements for a stable foundation, compliant clearances, protection from unsuitable site conditions and installation by a qualified person. The complete system is documented for on-grid, backup and off-grid applications with a compatible inverter.

Stock and exact-generation check

The module is held in European supplier stock. Because the supplier line identifies HVM but not the exact manufacturer reference, the module label, original HVM generation, cell-version weight, serial number and applicable warranty conditions are confirmed before the order is accepted. This prevents a later HVM+ or BCU2.0 component from being mixed into an original HVM tower by assumption.
