Add flexible Storage to Solar Module projects with BYD Battery Box Premium HVS+ 2.56kWh Lithium Battery

The BYD Battery Box Premium HVS+ 2.56kWh Lithium Battery is the core module used to build BYD Battery-Box HVS+ towers, giving installers a premium route to Storage upgrades on Solar Module installations. It enables customers to store surplus solar generation for evening use, improve self-consumption and add resilience through backup-capable system designs, while keeping the system easy to expand as needs change.

Modular capacity that fits the site today and scales tomorrow

Each module provides 2.56kWh designed capacity and forms part of a tower from 2 to 5 modules, delivering usable energy from 5.12kWh up to 12.8kWh per tower. For bigger homes and small commercial sites, you can parallel up to three towers for a total maximum capacity of 38.4kWh. That scalability makes it simple to propose a phased Storage roadmap alongside Solar Module expansion, EV charging or electrified heating.

  • Module: HVS+ (2.56kWh, 102.4V, 38.5kg)
  • Tower options: 5.12kWh to 12.8kWh usable energy
  • Parallel expansion: up to 3 towers, max 38.4kWh

Installer-friendly design for faster, cleaner builds

BYD focuses on practical installation details that help you standardise work on site. A patented internal plug connection supports quick stacking, with smart configuration and flexible wiring that reduces time spent on interconnects. The system is floor-mounted and designed for indoor or outdoor placement, giving you more options when plant-room space is tight.

  • Patented internal plug connection for rapid tower assembly
  • Installation scene: indoor or outdoor, IP55 enclosure rating
  • Storage humidity: 5 to 95 percent, altitude: under 3000m

High performance Storage with stable, safe LFP chemistry

Built around lithium iron phosphate cells, the BYD Battery-Box HVS+ platform combines high efficiency with a safety-first design from cell to pack. Round-trip efficiency is specified at at least 95 percent, supporting strong customer outcomes in day-to-day solar self-consumption. Per tower, the platform supports up to 12.8kW charge and discharge power, designed to keep pace with real household and small commercial loads.

  • Round-trip efficiency: at least 95 percent
  • Max output current: 25A, peak: 55A for 15 seconds
  • Operating temperature: -10°C to +50°C

Smart management and wide inverter compatibility to strengthen your offer

From commissioning through aftercare, intelligent management features help you keep customer systems performing well. The datasheet highlights automatic state-of-charge adjustment, remote diagnosis and OTA updates, supporting faster troubleshooting and fewer site visits. With CAN and RS485 communications and compatibility with leading single-phase and three-phase inverters, the BYD Battery Box Premium HVS+ 2.56kWh Lithium Battery helps you deliver a premium Storage add-on that complements Solar Module proposals across a wide range of projects.
