Serious storage for larger homes and heavier loads. The BYD Battery-Box Premium HVM 22.1 packs 22.08 kWh of LiFePO4 into a single high-voltage tower — with the density to run a large home, an EV-heavy household or a small business through outages and onto cheaper energy.
Why it stands out
Built on the same platform as Europe’s #1 battery series, the HVM scales from 8.3 kWh to 22.1 kWh per tower and parallels up to three towers for 66 kWh. Modular, IP55-rated and compatible with the industry’s leading hybrid inverters, it grows with your energy demands instead of being replaced by them.
