The most-installed home battery in Europe. The BYD Battery-Box Premium HVS 10.2 is a modular 10.24 kWh LiFePO4 high-voltage tower — Europe’s market-leading residential battery, trusted by more installers than any other brand. Paired with a hybrid inverter, it stores cheap or solar power and releases it when you need it.
Why it stands out
BYD’s vertical integration (cell to pack to system) delivers the best €/kWh among top-tier brands, plus the widest inverter compatibility in the industry — Fronius GEN24, Kostal, SMA, Sungrow and more. Clean power for backup, lower bills through time-of-use shifting, and peak-shaving to cut grid charges.
