BYD B-Box Premium HVS 7.7 kWh Lithium Battery

Product Description

The BYD B-Box Premium HVS 7.7 kWh Lithium Battery combines 3 HVS modules of 2.56 kWh on a Base and an upper BCU to provide 7.7 kWh usable at a nominal 307 V. With LFP chemistry (LiFePO₄, cobalt-free), ≈96 % efficiency, and IP55 rating, its modular plug-in architecture simplifies installation, maintenance, and future expansions. CAN/RS485 communication with BYD profile ensures native integration with leading HV inverters.

Main Features

• Usable energy: 7.7 kWh (3× HVS 2.56).
• Nominal voltage: 307 V (240–360 V).
• Current: 25 A continuous; 50 A peak 5 s.
• Chemistry: cobalt-free LFP; efficiency ≈96 %.
• Protection: IP55; plug-in connection between modules.

Advantages or Benefits

• Modular and scalable: expand by modules up to 12.8 kWh/tower or in parallel up to 3 towers (3-3-3).
• Superior safety: LFP thermal stability and intelligent management via BCU.
• Rapid integration: CAN/RS485 communication with single-phase and three-phase HV inverters.
• Clean installation: no internal wiring, reduced assembly time and errors.

Purpose or Applications

Residential/commercial self-consumption, reliable back-up, and off-grid systems requiring compact, safe, and efficient HV storage.
