Battery overview
Build Commercial Storage Around Your Project
The Bluesun BSM48106H is a modular high-voltage LiFePO4 rack battery system. A 51.2V 106Ah module contributes approximately 5.42kWh; cabinet energy is specified as 5.42 × N kWh, where N is the configured module count.
Battery modules work with a high-voltage main controller and rack structure. For larger installations, the documented architecture also includes a DC bus cabinet for system-level communication and protection.
The final configuration is selected around the PCS operating voltage, required energy, load profile and installation conditions. The cabinet image illustrates the product architecture rather than a fixed capacity included in every order.
Three-Level Battery Management
Cell, battery cluster and system management coordinate monitoring, balancing and protection.
High-Voltage System Architecture
Series-connected modules build system voltage for integration with compatible PCS equipment.
Communication & Integration
The documentation lists CANBUS, Modbus RTU and TCP/IP interfaces at the battery-system level.
Applications
Configured for Commercial Energy Projects
Specify the required energy, power, operating voltage and PCS model before selecting the battery cabinet configuration.
Commercial Solar Storage
Battery storage for compatible commercial solar-plus-storage projects, configured to the required energy and PCS architecture.
Site Backup Power
Support selected site loads with a correctly designed battery, PCS, control and protection system.
Larger Battery Installations
Multiple rack configurations can be evaluated with system-level management and DC bus equipment for larger projects.

Understand Your Cabinet Capacity
N is the configured number of battery modules. Energy examples below use the confirmed rounded value of 5.42kWh per module; they are illustrative calculations rather than a published list of available cabinet packages.
409.6 V nominal system voltage
512 V nominal system voltage
614.4 V nominal system voltage
Confirm the permitted module count, complete charging voltage window and PCS compatibility before ordering. The controller rating alone does not establish the acceptable configuration.
Module capacity is shown as 106Ah and approximately 5.42kWh, as confirmed for this product. Other values follow the supplied technical tables. Module and system operating limits are listed separately.

Product FAQ
High-Voltage Rack Battery FAQs
Understand module energy, cabinet configuration and system integration before specifying a project.
What is the energy of one battery module?+
This product uses the confirmed 51.2V 106Ah module version, presented as approximately 5.42kWh per module. The supplied PDF retains an earlier 100Ah / 5.12kWh parameter table.
How is the battery cabinet capacity calculated?+
Cabinet energy is approximately 5.42 × N kWh, where N is the configured module count. Confirm the final system specification and permitted module count with Bluesun.
Is the complete cabinet a 51.2V battery?+
51.2V is the nominal voltage of one module. Series-connected modules increase the system nominal voltage to 51.2 × N V; the cabinet operates as a high-voltage battery system.
Is the pictured cabinet capacity fixed?+
No. The product image shows a rack configuration. The number of modules, resulting capacity, controller, DC bus equipment and project scope must be specified in the quotation.
What is the difference between the module and system DoD?+
The supplied technical tables list 80% depth of discharge for the battery module and 90% for the system. These are distinct documented ratings; the delivered system settings must follow the confirmed configuration.
Does the cabinet include an inverter or PCS?+
The battery documentation describes modules, a high-voltage controller, rack and DC bus architecture. PCS, inverter, EMS and other project equipment must be confirmed separately in the project scope.
Which information is needed for a quotation?+
Provide the required storage energy, charge and discharge power, PCS model and voltage range, application, installation environment and desired quantity.
