HV BYD Battery-Box Premium HVM+ lithium battery 22.1 kWh

HV BYD Battery-Box Premium HVM+ lithium battery 22.1 kWh

BYD, the world's leading manufacturer of batteries and electric mobility solutions, is once again updating its range of high-voltage batteries with the arrival of the new Battery-Box Premium HVM+ series.
This direct evolution of the successful HVM line offers higher capacity per module, more power, better efficiency and extended compatibility with leading inverters on the market.

The HV BYD Battery-Box Premium HVM+ 22.1 kWh lithium battery is part of the new HVM+ generation, designed to provide robust, modular and easily scalable storage in self-consumption, hybrid or backup power installations.

Thanks to its stackable architecture and “plug & play” design, it allows a quick, safe and expandable installation, adapting to the energy needs of both homes and small industries.

Why choose the BYD Battery-Box Premium HVM+ 22.1 kWh?

Battery-Box Premium HVM+ 22.1 kWh consists of 1 unit BCU+Base for HV Lithium Battery BYD Battery Box Premium HVS+ / HVM+ - 16541149-00 y 8 2.76 kWh HVM+ modules each, offering a total useful capacity of 22.1 kWh.

Each tower can be expanded by adding additional HVM+ modules, up to a maximum of 8 modules (22.1kWh) per tower.

This combination constitutes a high-voltage tower capable of delivering high continuous power and managing energy with precision, thanks to the integrated intelligent BMS (Battery Management System).

The BCU's integrated Battery Management System (BMS) manages the power flow in real time: it balances the cells, monitors temperature, voltage and state of charge, and protects against overcharging, over-discharging or short circuits. This approach enables reliable, safe performance and a long service life.

Main functions of the BYD Battery-Box Premium HVM+ 22.1 kWh

Intelligent management and control

The BMS system continuously monitors voltage, current and temperature of each module, optimising charging and discharging strategies, balancing the cells.
In this way, the battery operates stably and efficiently, maximising its durability and available energy.

Safety and security

It includes internal protections against overload, deep discharge, short-circuit and overtemperature.
It complies with the main international safety standards: IEC 62619, UN 38.3, CE, VDE 2510-50, guaranteeing electrical, mechanical and thermal safety.

Advanced communication

It includes CAN and RS485 interfaces, enabling seamless, bi-directional communication with leading inverters on the market.
This compatibility facilitates an intelligent integration of the energy flow between the PV array, the battery and domestic or industrial consumption.

Modular and scalable design

The HVM+ series allows 3 to 8 modules to be stacked vertically on a BCU + Base, without internal wiring, making it easy to expand the system in the future without the need to replace the base unit. The 22.1 kWh model consists of 8 HVM+ modules (2.76 kWh each).

HVM+ modules are not compatible with earlier standard HVM versions in the same tower, and towers of different versions cannot be mixed in parallel.

Efficient and stable storage

The battery uses lithium-ferrophosphate (LiFePO₄, LFP) technology, a cobalt-free chemistry that offers high thermal stability, good longevity, low degradation with charge/discharge cycles, increased structural safety and improved performance against overheating or adverse reactions.

Quick and safe installation

The plug & play design allows for easy commissioning, without the need for internal wiring between modules.
The modules are stacked vertically on the base, which reduces installation times and minimises errors.
Thanks to its modular architecture, future expansion is very easy.

Robust and modular structure

The Battery-Box Premium HVM+ features a reinforced metal housing, a compact, vertical design optimised for heat dissipation and precise mechanical alignment, which makes the most of space and ensures performance even in demanding environments. It is designed for floor installation, with protection against water and dust (IP55 rating).

Compatibility between BYD battery systems

The Battery-Box Premium HVM+ 22.1 kWh belongs to the new generation of HVM+ batteries, compatible only with the HVM+ series and the new generation BCU + Base unit 16541149-00.

Battery-Box Premium HVM+: Stackable from 3 to 8 modules (8.28 - 22.08 usable kWh).

HVM+ modules are not compatible with previous standard HVM versions, so they cannot be combined with modules or BCUs from previous versions. They cannot be mixed in the same tower or put new towers in parallel with towers of modules from previous versions.

Compatibility with inverters

The HV BYD Battery-Box Premium HVM+ lithium batteries are compatible with a wide range of market-leading inverters such as Fronius, GoodWe, SMA, Kostal, Victron, Huawei or Solis.
This compatibility ensures easy integration into self-consumption systems with storage, hybrid installations or backup configurations.

Advantages of the new BYD Battery-Box Premium HVM+ 22.1 kWh battery

Simple installation

The HMV+ features a vertically stackable system with no internal wiring between modules, reducing installation errors and assembly times.
Thanks to this system, capacity expansion is achieved by simply adding new modules on top of the existing tower, allowing the system to be scaled up in the future without the need to replace base components.

Minimal maintenance

The fanless design with no fans or moving parts, together with passive cooling and IP sealing, reduces the need for preventive maintenance and ensures quiet operation.

Seamless integration with state-of-the-art inverters

Includes updated communication profiles for Fronius GEN24 Plus, GoodWe ET Plus+, SMA Sunny Boy Storage, Kostal Plenticore Plus, Victron Multiplus II and others.

Modular and expandable installation

It allows a configuration of 7 modules (19.3 kWh) and can be expanded as needed without changing the base unit, simply by adding more modules on top of the existing tower.

Example of a BYD Battery Box Premium HVM+ installation

A typical battery, the BYD Battery Box Premium HVM+ 22.1 kWh, includes:

1 × BCU+Base - 16541149-00
8 × HVM+ modules, 2,76 kWh each

With this configuration, a useful capacity of 22.1 kWh is obtained, enough to cover the night-time consumption of many homes or offices. In the event of an increase in demand, towers could be connected in parallel.

Recommended installation of a high-voltage lithium battery

• Location: dry indoors, on a stable surface, away from moisture or heat.
• Assembly: the BCU+Base is installed first; the modules are stacked on top vertically with plug & play connection, without internal cables. They are snapped together using the integrated connectors.
• Connection: power and communication cables are connected directly from the BCU via CAN / RS485 protocols to the inverter, without additional wiring between modules.
• Commissioning: This is done from the compatible inverter interface, which automatically detects the battery and configures the system according to the parameters of the BMS (Battery Management System).
• Compatibility: Exclusively with new generation BYD Premium HVS+ and BCU+Base systems.

What is the warranty on HV BYD Battery Box Premium HVS+ / HVM+ lithium batteries?

BYD offers a 10-year warranty, covering both the BCU and the battery modules, provided that the system has been installed according to official specifications and with approved inverters.
