BYD B-Box Premium HVM 19.3 kWh Lithium Battery

Product Description

The BYD B-Box Premium HVM 19.3 kWh Lithium Battery is a high-voltage tower composed of 7 HVM modules of 2.76 kWh, stacked on a Base and managed by the upper BCU. It provides 19.3 kWh usable at a nominal voltage of 358 V, with LFP chemistry (LiFePO₄, cobalt-free), plug-in architecture without internal wiring, round-trip efficiency close to 96%, and IP55 protection. Its modular design facilitates expansions, quick maintenance, and native integration with HV inverters via CAN/RS485 communication with BYD profile.

Main Features

• Usable energy: 19.3 kWh (7× HVM 2.76).
• Nominal voltage: 358 V (typical range 280–420 V).
• Safe chemistry: LiFePO₄ (LFP), cobalt-free.
• Current: 50 A continuous; 75 A peak 5 s.
• Round-trip efficiency: ≈96%.
• Protection rating: IP55.
• Connection between modules: plug-in, no internal cables.

Advantages or Benefits

• Modular and scalable: possibility to expand up to 22.1 kWh per tower or operate in parallel (up to 3 towers with the same number of modules).
• Safety and reliability: stable LFP chemistry, with BCU coordinating SOC/SOH and event logging.
• Professional integration: CAN/RS485 communications for leading HV inverters.
• Agile maintenance: stackable format that simplifies replacements and expansions.

Purpose or Applications

Recommended for residential/commercial self-consumption with medium-high demand, systems with power back-up, peak-shaving, and off-grid projects requiring high, stable voltage with maximum safety and efficiency.

Technical Specifications

Compatibilities
