From One Module to a 16-Module Rack
The supplied table specifies a 16-module configuration. The values below show the module rating and the resulting nominal cabinet energy and voltage.
51.2 V nominal system voltage
819.2 V nominal system voltage
Discharge lower limit to charge upper limit
Cabinet energy = 16.076 × N kWh. Nominal voltage = 51.2 × N V. At N = 16, the published voltage formulas give 716.8V discharge lower voltage and 896V charge upper voltage. Confirm full PCS and battery compatibility for the delivered configuration.
Values follow the supplied BSM48314H technical tables. The 257.216kWh and 819.2V figures are calculated from the documented 16-module configuration; they are rated energy and nominal voltage, not usable energy or guaranteed site performance.

Product FAQ
BSM48314H Rack Battery FAQs
Understand module energy, cabinet configuration and system integration before specifying a project.
What is the energy of one BSM48314H battery module?+
The module parameter table lists 51.2V nominal voltage, 314Ah nominal capacity and 16.076kWh rated energy.
What is the capacity of the published 16-module configuration?+
Sixteen 16.076kWh modules provide 257.216kWh of rated energy. Sixteen 51.2V modules in series give 819.2V nominal system voltage.
What are the system current ratings?+
The system table lists 157A standard operation current, 157A normal operation current and 314A maximum operation current. The BSM1000V300A main controller has its own 1000V / 300A rating.
What is the difference between the module and controller protection classes?+
The supplied tables list IP22 for the battery module and IP20 for the main controller. These component ratings do not establish a separate outdoor protection rating for the assembled rack.
What is the system voltage range at 16 modules?+
Using the published formulas, 44.8 × 16 gives 716.8V at the discharge lower limit and 56 × 16 gives 896V at the charge upper limit. Nominal system voltage is 819.2V.
Does the system include a PCS or inverter?+
The document covers the battery module, high-voltage controller, rack system and DC bus cabinet. PCS, inverter, EMS and other project equipment must be confirmed separately in the quotation.
What should I provide for a project quotation?+
Share required storage energy, charge and discharge power, PCS model and DC voltage window, installation conditions, project location and quantity.
How do the controller and system current ratings compare?+
The supplied controller table lists BSM1000V300A at 300A nominal current, while the system table lists 314A maximum operation current. These are separate published component and system ratings; confirm the permitted continuous and peak operating limits for the delivered configuration with Bluesun.
