BYD B-Box Premium HVM 16.6 kWh Lithium Battery

Product Description

The BYD B-Box Premium HVM 16.6 kWh Lithium Battery is an HV tower with 6 HVM modules of 2.76 kWh (on Base and with upper BCU) that delivers 16.6 kWh usable at a nominal voltage of 307 V. Its cobalt-free LFP chemistry offers maximum safety and durability, while the modular plug-in design facilitates expansion and maintenance. With a round-trip efficiency close to 96 % and IP55 protection, it is a robust option for demanding residential and commercial systems.

Main Features

• Usable capacity: 16.6 kWh (6× HVM 2.76 kWh).
• Nominal voltage: 307 V (typical range 240–360 V).
• Current: 50 A continuous; 75 A peak 5 s.
• Chemistry: LiFePO₄ (LFP), cobalt-free.
• Round-trip efficiency: ≈96 %.
• Protection: IP55 (indoor/protected outdoor).
• Communications: CAN/RS485 (BYD profile) with HV inverters.

Advantages or Benefits

• Superior scalability: expands by modules up to 22.1 kWh/tower or in parallel up to 3 towers.
• Native integration: direct compatibility with leading HV inverters.
• Safety and reliability: BCU coordinates BMS, balancing, and event logging.
• Optimized installation: organized architecture and no internal wiring between modules.

Purpose or Applications

Self-consumption with full back-up, peak-shaving, and off-grid projects that require high voltage, high power, and maximum availability with LFP chemistry.
