HV BYD Battery-Box Premium HVM+ lithium battery 8.3 kWh

HV BYD Battery-Box Premium HVM+ lithium battery 8.3 kWh

BYD, a leading manufacturer of batteries and electric mobility solutions, is once again updating its high-voltage batteries. The new HV Lithium Batteries BYD Battery Box Premium HVM+ is the direct evolution of the successful HVM series. This new battery offers higher capacity, more power and extended compatibility with the main inverters on the market.

The HV BYD Premium HVM+ 8.3 kWh lithium-ion battery is part of BYD's new HVM+ family of high-voltage batteries, designed to offer higher capacity per module, industrial robustness and easy integration in self-consumption and backup installations that require more autonomy than the HVS+ series.

Thanks to its modular, stackable architecture, the Battery-Box Premium HVM+ 8.3 kWh allows for fast, safe and scalable installation, adapting to the needs of any residential or industrial PV system.

Why choose the BYD Battery-Box Premium HVM+ 8.3 kWh?

The HV BYD Battery-Box Premium HVM+ 8.3 kWh lithium-ion battery consists of 1 unit BCU+Base for HV Lithium Battery BYD Battery Box Premium HVS+ / HVM+ - 16541149-00 y 3 2.76 kWh HVM+ modules each, thus reaching a useful capacity of 8.28 kWh.

Each tower can be expanded by adding additional HVM+ modules up to 22.1kWh (8 modules).

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+ 8.3 kWh

Intelligent management and control

The BMS system continuously monitors voltage, current and temperature of each module, ensuring efficient and stable operation. In addition, it optimises the use of stored energy to prolong the life of the system.

Safety and security

It includes internal protections against overload, deep discharge, short circuit and extreme temperatures.
The battery complies with international standards such as VDE 2510-50, IEC 62619, UN 38.3, CE, guaranteeing electrical, mechanical, thermal and transport safety.

Advanced communication

It integrates CAN and RS485 interfaces, enabling seamless, bi-directional communication with leading inverters on the market.
This bi-directional communication enables intelligent management of the energy flow between the PV array, the battery and the household consumption.

Quick and safe installation

The plug & play design allows for easy commissioning with no internal wiring between modules. Modules stack vertically on the base, reducing installation time and minimising errors.

Robust and modular structure

The Battery-Box Premium HVM+ 8.3 kWh has a reinforced metal housing, a vertical design optimised for heat dissipation and precise mechanical alignment to ensure performance even in demanding environments.

Modular and scalable design

The HVM+ series allows 3 to 8 modules to be stacked vertically on a BCU+Base, without internal wiring, which facilitates future expansion without replacing the base unit. The 8.3 kWh model consists of 3 HVM+ modules (2.76 kWh each).

Efficient and stable storage

The modules use lithium-ferrophosphate (LiFePO₄, LFP) technology, a cobalt-free chemistry, which provides high thermal stability, good longevity, low degradation with cycling, structural safety, increased safety against overheating and adverse thermal reactions.

Compatibility between BYD battery systems

The Battery-Box Premium HVM+ 8.3 kWh is part of BYD's new generation of high-voltage batteries, and is exclusively compatible with the HVM+ series and the new generation BCU+Base unit.

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 Premium HV lithium battery HVM+ 8.3 kWh

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 you to start with a small configuration of three modules and expand it in the future without changing the base unit, simply by adding more modules.

Example of a BYD Battery Box Premium HVM+ installation

A typical battery, the BYD Battery Box Premium HVM+ 8.3 kWh, includes:

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

With this configuration, a useful capacity of 8.28 kWh is obtained, sufficient to cover the night-time consumption of many homes or small offices. In the event of increased demand, 1 or more modules can be added up to the maximum tower configuration (8 modules) or towers can 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.
