BYD Battery-Box HVM+ 22.1: Ultimate Power & Capacity
The BYD Battery-Box HVM+ 22.1 is the largest single-tower configuration in the HVM+ series. Boasting a massive 22.08 kWh usable capacity and a nominal voltage of 409V, this system is engineered for high-demand residential and small commercial applications. It offers the perfect solution for users seeking total energy independence, efficient EV charging, and robust backup power capabilities.
- Massive Capacity: 22.08 kWh usable energy (100% DOD)
- High Efficiency: 409V nominal voltage minimizes losses
- Powerful Output: 50A continuous discharge for heavy loads
- Durability: IP55 rated for indoor and outdoor use

What is included in the box?
You receive a complete system ready for assembly:
- 1x BCU (Battery Control Unit) & Base
- 8x HVM+ Battery Modules
- 1x Smart WiFi/LAN Module
- Power connectors & Terminal resistor
- Wall brackets (Essential for stability due to height)
Inverter Compatibility?
The HVM+ 22.1 requires a high-voltage hybrid inverter capable of handling voltages up to 460V. We recommend:
- Solis: S6 3-Phase Hybrid Series
- GoodWe: ET Series
- Fronius: Symo GEN24 Plus
- Kostal: Plenticore Plus
Is it scalable?
Yes. You can connect up to 3 identical HVM+ 22.1 towers in parallel, achieving a total capacity of 66.2 kWh. This is ideal for off-grid setups or light commercial storage.
Is this suitable for Time-of-Use / Dynamic Tariffs?
Yes. A large 22kWh battery allows you to store significant amounts of cheap energy during off-peak hours and use it during peak times. The high cycle life of the LiFePO4 cells ensures the system remains profitable even with daily deep cycling.
Safety & Installation
Despite the total weight of 345kg, installation is manageable as modules are stacked individually. The system uses Cobalt-free LFP chemistry (safest on the market) and complies with strict VDE2510-50 standards.
