Deye BOS-G-PRO 3U-LRACK – High Voltage Battery Rack for 8 × 5.12kWh Batteries
Deye BOS-G Pro 3U-LRACK battery rack for up to 8 × BOS-G-Pack5.1 5.12kWh high-voltage LiFePO4 battery modules, supporting up to 40.96kWh of nominal battery storage with the BOS-G-PDU-2 control box.
Deye BOS-G Pro 3U-LRACK Battery Rack
The Deye BOS-G Pro 3U-LRACK is a dedicated battery rack designed to house up to 8 Deye BOS-G-Pack5.1 5.12kWh high-voltage LiFePO4 battery modules, together with the BOS-G-PDU-2 high-voltage control box.
It forms part of the modular Deye BOS-G Pro high-voltage battery energy storage system, providing a structured rack-mounted solution for residential, commercial and industrial solar energy storage.
When fully populated with eight BOS-G-Pack5.1 modules, the rack accommodates 40.96kWh of nominal battery storage.
Designed for Deye BOS-G Pro HV Batteries
The 3U-LRACK is specifically designed for the Deye BOS-G Pro battery platform and accommodates:
-
Up to 8 × BOS-G-Pack5.1 battery modules
-
5.12kWh per battery module
-
40.96kWh maximum nominal battery capacity
-
1 × BOS-G-PDU-2 high-voltage control box
This configuration provides a compact way to install a substantial amount of high-voltage battery storage within a single rack.
40.96kWh High-Voltage Battery Storage
With eight BOS-G-Pack5.1 modules installed:
8 × 5.12kWh = 40.96kWh nominal capacity
The BOS-G-Pack5.1 uses LiFePO4 chemistry and forms the energy-storage component of the BOS-G Pro system. The battery modules are managed and protected through the BOS-G-PDU-2 control box.
The resulting high-voltage battery system is suitable for applications requiring significant energy storage for solar self-consumption, backup power and energy management.
Compact Rack-Mount Solution
The 3U-LRACK provides a more compact alternative to the larger 12-battery 3U-HRACK.
Its capacity for eight battery modules makes it well suited to installations where approximately 41kWh of nominal storage is required while keeping the battery system organized within a dedicated rack.
The rack accommodates the battery modules together with the BOS-G-PDU-2 control box as part of the BOS-G Pro system configuration.
Ideal for Solar & Energy Storage Systems
The Deye BOS-G Pro 3U-LRACK can be used as part of high-voltage battery systems for:
-
Solar energy storage
-
Commercial solar installations
-
Industrial energy storage
-
Backup power
-
Load shifting
-
Peak-load management
-
Renewable-energy storage
-
Farms
-
Schools
-
Banks
-
Supermarkets
-
Small factories
The modular BOS-G Pro design also allows larger installations to be built using multiple battery racks or clusters.
Modular & Scalable Battery Storage
The BOS-G Pro platform uses 5.12kWh modular battery packs, allowing storage capacity to be matched to the requirements of the installation.
The 3U-LRACK supports up to eight battery modules, providing a maximum nominal capacity of 40.96kWh per rack.
For installations requiring more storage, the BOS-G Pro architecture supports multiple racks/clusters in parallel, allowing the overall battery system to be expanded substantially.

Important: Rack Only
The Deye 3U-LRACK is the battery rack only and does not include the BOS-G-Pack5.1 battery modules or BOS-G-PDU-2 control box unless specifically stated in the product listing.
The batteries, control box, cables and other BOS-G Pro components are separate system components and must be selected according to the required configuration.
Why Choose the Deye 3U-LRACK?
The Deye BOS-G Pro 3U-LRACK provides an efficient rack-mounted solution for installations requiring up to 40.96kWh of nominal high-voltage battery storage.
Its eight-module capacity makes it an excellent choice for customers looking for a scalable commercial or larger residential battery system without immediately requiring the full 12-module capacity of the 3U-HRACK.
Combined with Deye BOS-G-Pack5.1 batteries and the BOS-G-PDU-2, the 3U-LRACK forms part of a powerful, modular high-voltage energy storage platform.
