BYD Battery-Box Premium HVS-HVM Solar Battery
At Trione Energy, we proudly supply, install and support the BYD Battery-Box Premium HVS-HVM.
The BYD Battery-Box Premium HVS-HVM is a high-voltage, modular LFP (lithium iron phosphate) storage solution engineered for flexibility and long-term performance.
With a capacity range from 5.1 kWh (HVS) to 22.1 kWh (HVM) on a single unit, and scalable up to 38.4 kWh (HVS) or 66.2 kWh (HVM) in parallel stacks, this system suits growing homes, commercial settings and off-grid applications.
Key Features
- Modular scalability – Build capacity gradually: Achieve 5.1–12.8 kWh with HVS (2–5 modules), or 8.3–22.1 kWh with HVM (3–8 modules), and stack up to 3 units in parallel for up to 66.2 kWh.
- Plug-and-play design – Patented internal plug architecture eliminates inter-module wiring, simplifying installation and future expandability.
- High-voltage series connection – Delivers efficient charge/discharge performance and supports high-power backup and off-grid functionality.
- Cobalt-free LFP chemistry – Offers enhanced safety, long lifespan, and stable power output.
- External inverter compatibility – Works seamlessly with leading 1-phase and 3-phase high-voltage inverters.
- Rugged and efficient – Built to high safety standards such as VDE 2510-50, with IP55 environmental protection and minimal temperature derating below 0 °C.
- Enhanced design – Updated HVM modules are ~30% lighter and ~8 cm slimmer than predecessors, optimising space usage.
