The BYD Battery-Box HVB is a modular high-voltage battery energy storage system for photovoltaic applications, featuring Lithium Iron Phosphate (LiFePO4) cells with BYD Blade Battery technology and a cell-to-pack architecture.
The system consists of 2.97 kWh battery modules, which can be connected in series in configurations ranging from 2 to 10 modules per tower, providing a usable capacity of 5.94 to 29.69 kWh. Up to three towers can be connected in parallel, achieving a maximum total storage capacity of 89.07 kWh.
Electrical Characteristics
The nominal voltage ranges from 102.4 V to 512 V, depending on the number of installed modules, with an overall operating voltage range of 80 V to 576 V, depending on the configuration.
The system offers the following specifications:
- Maximum output current: 50 A.
- Peak current: 98 A for 15 seconds.
- Round-trip efficiency: ≥95%.
- Inverter communication via CAN/RS485.
- Applications: on-grid, on-grid with backup and off-grid, when paired with compatible inverters.
Installation and Battery Management
The modular design with integrated plug-and-play connections simplifies assembly and reduces inter-module cabling. The system is designed for floor-mounted installation and supports future capacity expansion in accordance with the manufacturer’s guidelines.
Intelligent battery management features include automatic State of Charge (SOC) calibration, remote diagnostics and Over-the-Air (OTA) firmware updates. The BYD Smart Wi-Fi/LAN connectivity module is available as an optional accessory.
Dimensions, Protection and Safety
Each battery module weighs 27.3 kg. Overall tower dimensions vary depending on the configuration, from 479 × 610 × 282 mm with two modules to 1,327 × 610 × 282 mm with ten modules.
The battery features an IP55 protection rating and an operating temperature range from -20°C to +50°C, with possible performance derating at lower temperatures.
The BYD Battery-Box HVB series is declared compliant with IEC 62619, VDE 2510-50, UN 38.3 and applicable CE requirements. It is covered by a 15-year manufacturer’s warranty, subject to the applicable warranty terms and conditions.
