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 = 14.336 × 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 BSM48280H technical tables. The 229.376kWh 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.

The module parameter table lists 51.2V nominal voltage, 280Ah nominal capacity and 14.336kWh rated energy.
What is the capacity of the published 16-module configuration?+
Sixteen 14.336kWh modules provide 229.376kWh 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 140A standard operation current, 140A normal operation current and 280A 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.
