HV BYD Premium HVS+ 2.56 lithium battery module - 18487497-00

HV BYD Premium HVS+ 2.56 lithium battery module - 18487497-00

BYD, a leading manufacturer of batteries and electric mobility solutions, is once again upgrading its high-voltage batteries. The new HV BYD Battery Box Premium HVS+ lithium batteries are the direct evolution of the successful HVS series. These new batteries offer higher capacity, more power and extended compatibility with leading inverters on the market.

The HV lithium battery module BYD Premium HVS+ 2.56 - 18487497-00 is part of the new generation of high-voltage energy storage systems BYD Battery Box Premium HVS+, developed to offer maximum efficiency, safety and scalability in residential, commercial or industrial photovoltaic installations.

Each HVS+ module represents a useful 2.56 kWh storage unit, which can be combined with other modules of the same series to form towers with capacities from 5.12 kWh to 12.8 kWh, depending on the user's needs.

Designed to work in conjunction with the BCU+Base for HV Lithium Battery BYD Battery Box Premium HVS+ / HVM+ - 16541149-00, This module forms the fundamental energy block of the new BYD high-voltage batteries.

Main functions of the HV BYD Premium HVS+ 2.56 lithium battery module HV BYD Premium HVS+ 2.56

Modular and scalable design

The HVS+ system allows 2 to 5 modules to be stacked on a BCU+Base unit, without the need for internal wiring.
The plug & play connection facilitates fast, clean and safe installation, reducing assembly times and possible connection errors.

Efficient storage

Each HVS+ module offers 2.56 kWh of useful capacity and exceptional performance thanks to its LFP (Lithium Iron Phosphate) chemistry, renowned for its high thermal stability, long life and improved safety compared to other lithium technologies.

Maximum safety and reliability

HVS+ modules comply with international standards IEC 62619, UN38.3 and CE, ensuring safe operation even under demanding conditions.
Its watertight construction and reinforced metal housing offer protection against impact and adverse environmental conditions.
In addition, its LFP technology makes the BYD Premium HVS+ safer, more stable and more durable.

Compatibility between BYD battery systems

The BYD HVS+ 2.56 module is exclusively compatible with the HVS+ series and the new generation BCU+Base unit.

Battery-Box Premium HVS+: Stackable from 2 to 5 modules (5.1 - 12.8 usable kWh).

The new HVS+ modules are not compatible with the old ones, so they cannot be combined with modules or BCUs of 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

BYD batteries guarantee technical consistency and full compatibility with the latest inverters on the market, such as Fronius, GoodWe, SMA, Kostal, Victron, Huawei or Solis.

Advantages of the new HV lithium battery module BYD Premium HVS+ 2.56

Simple installation

Thanks to the vertically stackable system without internal cabling, capacity expansion is done by simply adding new modules on top of the existing tower. This allows 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, ensures quiet, maintenance-free operation with a service life of more than 10 years under normal use.

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 two modules and expand it in the future without changing the base unit, simply by adding more modules.

Example of a BYD Battery Box Premium HVS+ installation

A typical battery, the BYD Battery Box Premium HVS+ 5.12 kWh, includes:

1 × BCU+Base - 16541149-00
2 × HVS+ modules (2.56 kWh each)

Total capacity: 5.12 usable kWh (expandable up to 12.8 kWh by stacking up to 6 modules)

With this configuration, the consumption of a single-family house can be fed with an average consumption of up to 5kWh during the night. How long the battery can last depends on the consumption and its charge level. The higher the charge percentage when using the battery and the lower the consumption, the longer it lasts.

Recommended installation of a high-voltage lithium battery

LocationIndoors dry, on a stable surface, away from sources of heat or humidity.
AssemblyBattery modules are stacked vertically on the BCU with plug & play connection and snapped in via the integrated connectors.
Communication: Managed by 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?

The HVS+ 2.56 module - 18487497-00 comes with a 10-year official BYD warranty, provided it is installed according to specifications and together with the approved BCU+Base.
