BYD Battery Box Premium HVB 2.97kWh Lithium Battery for higher-value Solar Module installs

The BYD Battery Box Premium HVB 2.97kWh Lithium Battery helps you turn a standard Solar Module installation into a smarter energy system your customers can feel every day. It stores surplus generation, supports evening consumption, and can add backup capability when paired with a compatible inverter. For installers, it is a clean, modular approach that scales with customer demand, making it easier to win projects today and secure future upgrades.

Modular storage that grows with the site

Each HVB module delivers 2.97kWh and stacks into a tower from 2 to 10 modules, giving usable capacities from 5.94kWh up to 29.69kWh per tower. Need more later? The system scales up to three towers in parallel for a maximum of 89.07kWh, so you can match storage to the customer’s Solar Module array size, load profile, and future electrification plans.

• Tower sizes: 2 to 10 modules, up to 29.69kWh usable per tower
• Scalability: max 3 towers in parallel, up to 89.07kWh total
• Extend anytime at any state of charge for straightforward upgrades

Installer-friendly handling and fast stacking

The HVB range is designed for efficient on-site work. Each module is under 30kg, supporting single-person handling, and a full tower stays under 1.3m for tidy plant-room layouts. A patented internal plug connection supports rapid stacking with fewer fuss points, helping you maintain consistent build quality across Solar Module and PV module projects.

• Module weight: 27.3kg, designed for manageable handling
• Installation mode: floor installation for stable, repeatable setups

High-voltage efficiency for better customer results

True high voltage supports strong system efficiency, helping customers capture more value from every kWh generated by their Solar Module array. Round-trip efficiency is specified at at least 95 percent, with high-power charge and discharge capability to keep pace with real household and small commercial loads.

• Max output current: 50A, peak: 98A for 15 seconds
• Applications: on-grid, on-grid plus backup, off-grid
• Operating temperature: -20°C to +50°C

Built-in safety, protection, and long warranty

BYD uses cobalt-free lithium iron phosphate cells developed in-house and proven at scale, supporting a strong safety story for customers investing in battery storage alongside Solar Module or solar panel systems. The solid case design and IP55 rating help protect the system in demanding environments, and a 15-year warranty supports long-term confidence at handover.

• Battery cell technology: lithium iron phosphate, cobalt-free
• IP class: IP55, storage humidity 5 to 95 percent
• Warranty: 15 years

Smart management and service-friendly monitoring

The BYD Battery Box Premium HVB 2.97kWh Lithium Battery includes intelligent management features such as automatic state-of-charge adjustment, remote diagnosis and OTA capability, helping you reduce site visits and support customers efficiently. Communication options include CAN and RS485, with an optional BYD smart WiFi and LAN module to enhance commissioning and aftercare on Solar Module projects.
