BYD Battery Box Premium HVS+ 2.56kWh Lithium Battery

• Manufacturer BYD

Using proven Lithium Iron Phosphate (LiFePO4) chemistry, the HVS+ platform is designed from cell to pack for maximum safety, with more than one million systems deployed worldwide. A round-trip efficiency of ≥95% helps maximise the usable energy from every cycle, improving system ROI for your customers. The module is rated at 102.4 V with an initial capacity of 2.56 kWh, and complete towers support up to 25 A continuous and 55 A peak (15 s) charge/discharge current, giving plenty of power headroom for modern hybrid inverters and backup operation.

For real-world installations, the HVS+ is built to handle tough conditions. The system operates from –10°C to +50°C (with automatic derating at low temperatures), is rated to IP55, and is suitable for indoor or outdoor floor-standing installation up to 3,000 m altitude. Typical applications include on-grid, on-grid with backup, and full off-grid systems, all backed by key certifications such as VDE 2510-50, IEC 62619, CE, UKCA and UN38.3.

Installers benefit from a modular, plug-together design with BYD’s patented internal plug connection, smart configuration and quick, flexible wiring. A built-in balancing optimiser and “extend anytime at any state of charge” capability make future system expansions straightforward. Intelligent management features including automatic state-of-charge (SOC) adjustment, remote diagnostics and OTA updates provide strong after-sales support options. The system is compatible with leading single- and three-phase inverters and is backed by a 10-year warranty, giving you a highly bankable storage solution for today’s advanced PV and backup projects.
