BYD Premium HVS 2.56 HV lithium battery module – 12911241-00

BYD Premium HVS 2.56 HV lithium battery module – 12911241-00

The BYD Premium HVS 2.56 – 12911241-00 lithium battery module is the core component of the BYD Premium HVS high-voltage storage system.
It is designed for both residential and industrial solar installations, offering a safe, efficient solution that is very easy to expand as energy needs grow.

Each HVS module provides 2.56 kWh of usable energy and can be combined with other modules from the same series to assemble towers with capacities ranging from 5.12 kWh to 12.8 kWh. Furthermore, if more energy is required, up to three towers can be connected in parallel to reach a maximum capacity of 38.4 kWh.

Thanks to its modular design and plug & play connection (no internal wiring), expanding the system is very simple: just add more modules on top of the tower, without any complications.

This module uses Lithium Iron Phosphate (LFP) technology, which stands out for its high thermal stability, high safety against overheating, and a service life exceeding 10 years. As it has no fans or moving parts, it requires little maintenance and operates completely silently.

The HVS module must be installed and works in conjunction with the BCU + BYD Battery Box Premium HVS Base, which acts as the system's control, communication and safety unit, managing energy flow and interaction with the inverter.

Key features of the BYD Premium HVS 2.56 lithium battery module

Modular and scalable design

The BYD Premium HVS system allows 2 to 5 HVS modules to be stacked in the same tower, connected in series and without internal wiring.
BYD's patented plug & play design simplifies installation, reduces errors and makes it easy to expand the system at any time by simply adding new modules.

Efficient storage

Each HVS module delivers 2.56 kWh of useful energy, with an efficiency greater than 96%.
Cobalt-free LFP (Lithium Iron Phosphate) cell technology ensures high thermal stability, high energy density and a long service life, even under intensive use conditions.

Maximum safety and reliability

BYD Premium HVS modules comply with the highest international safety standards, including IEC 62619, UN38.3, CE and VDE 2510-50, ensuring safe operation in both grid-connected systems and backup or isolated installations.
The reinforced metal casing and IP55 protection rating provide resistance to dust and moisture.

Compatibility between BYD battery systems

The BYD HVS 2.56 module is only compatible with the Battery Box Premium HVS system. and its corresponding BCU HVS.
It is not compatible with HVM systems or later versions (HVS+), and modules from different series cannot be mixed within the same tower or in parallel.

Compatibility with inverters

BYD Battery Box Premium HVS batteries offer broad compatibility with leading single-phase and three-phase inverters, including Fronius, SMA, Kostal, GoodWe, Victron, Huawei, and Solis, thanks to their CAN/RS485 communication and manufacturer-certified profiles.

The list of compatible investors is updated periodically by BYD and should be consulted prior to installation to ensure proper system integration.

Advantages of the BYD Premium HVS 2.56

Simple installation

The vertical stackable system without internal wiring allows for quick, clean, and safe installation, reducing assembly time and costs.

Minimal maintenance

The fanless, moving-part-free design, coupled with passive cooling, ensures quiet, virtually maintenance-free operation with a service life exceeding 10 years under normal operating conditions.

High power and versatility

The high actual voltage of the system, achieved by connecting the modules in series, allows for greater efficiency and power available for on-grid (connected to the electrical grid), on-grid with backup, and off-grid (isolated) applications.

Future scalability

The system allows you to start with a basic configuration and expand the energy capacity at any time without having to replace the BCU or other components.

Recommended installation of a high-voltage lithium battery

• Location: In a dry, well-ventilated indoor area, on a stable surface, away from sources of heat or humidity.
• Assembly: The battery modules are stacked vertically on top of the BCU with plug & play connection and are connected using 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: Exclusive with BYD Battery Box Premium HVS and BCU+Base systems

Guarantee

The BYD Premium HVS 2.56 HV lithium battery module comes with a 10-year official BYD warranty, provided it is installed in accordance with the manufacturer's specifications and as part of a complete HVS system.
