BYD Lithium Iron Batteries

The BYD Battery-Box Premium LVS is a modular lithium iron phosphate (LFP) battery pack for use with an external inverter.

Between 1 and 6 battery modules can be used in a single stack to give 4.0 to 24.0 kWh usable capacity.

Alternatively, up to 16 Battery-Box LVS stacks consisting of between 1 and 4 battery modules can be connected in parallel to give a maximum capacity of 256 kWh. Additional LVS modules or parallel stacks can be added at any time to increase capacity.

1 PDU base and cover is required for each battery stack and 1 BMU per system/inverter 

• Scalable from 4 kWh to 256 kWh
• Maximum flexibility for any application with up to 64 modules connected in parallel
• Compatible with market leading 1 and 3 Phase Inverters
• Cobalt Free Lithium Iron Phosphate (LFP) Battery: Maximum Safety, life cycle and power
• Capable of High-Powered Emergency-Backup and Off-Grid Function
• Patented Internal Plug Design Requires No Additional Wiring
• Self-Consumption Optimization for Residential and Commercial Applications

Maximum current at different temperatures

Note: Commissioning the battery requires a device capable of running the BYD Be Connect App - available for the Apple App Store and Google Play Store.

Excludes: Cat5 cable for communication between BMU and parallel stacks, 1x required per stack/PDU.

The BYD Battery-Box Premium LVL is a lithium iron phosphate (LFP) battery for use with an external inverter.
Thanks to its control and communication port (BMU), the Battery-Box Premium LVL scales to meet the project requirements, no matter how large they may be. Start with Battery-Box Premium LVL15.4 (15.36 kWh) and extend anytime to 983 kWh using parallel interconnection of up to 64 batteries.

• Scalable from 15.4 to 983 kWh
• Compatible with 1 and 3 Phase Inverters
• Cobalt Free Lithium Iron Phosphate (LFP) Battery: Maximum Safety, Life Cycle, and Power
• Capable of High-Powered Back-up and Off-Grid Function
• Space Saving via the Ability to Stack 2 Premium Batteries
• Add Additional Batteries in Parallel at Anytime to Expand System

Each system consisting of 1 inverter with up to 64 batteries requires 1 BMU.

Temperature derating: Like many lithium batteries temperature effects how fast the battery can change and discharge. These latest BYD batteries have a very wide operating temperature range and will work at their peak performance ratings most of the time in most installations. Discharging isn't effected much by temperature, charging is effected mostly: below 5°C charge rate will reduce to 0.3C, below -2°C 0.05C.

Note: Commissioning the battery requires a device capable of running the BYD Be Connect App - available for the Apple App Store and Google Play Store.

Includes: Cat5 cable for communication between BMU and parallel stacks.

One Battery-Box Premium HVS is composed of 2 to 5 HVS  battery modules (2 to 4 with the SMA Sunny Boy Storage Inverter) together with a BCU and Base, that are connected in series to achieve a usable capacity of 5.1 to 12.8 kWh.
Additionally, direct parallel connection of up to 3 identical Battery-Box Premium HVS allows a maximum capacity of 38.4 kWh.
Ability to scale by adding HVS modules or parallel HVS stacks later.

• Capable of High-Powered Emergency-Backup and Off-Grid Functionality
• Highest Efficiency Thanks to a Real High-Voltage Series Connection
• The Patented Modular Plug Design Requires no Internal Wiring and Allows for Maximum Flexibility and Ease of Use
• Cobalt Free Lithium Iron Phosphate (LFP) Battery: Maximum Safety, Life Cycle, and Power
• Compatible with Leading 1 and 3 Phase High Voltage Battery Inverters
• Two Distinct Modules to Cover the Complete Range of System Sizes
• Highest Safety Standards like VDE 2510-50
• IP55

Temperature derating: The BYD HVS only minimally derates at low temperature.

Note: Commissioning the battery requires a device capable of running the BYD Be Connect App - available for the Apple App Store and Google Play Store.
