DC battery cabinet for critical power
219.24 kWh Sodium-Ion UPS Battery CabinetA sodium-ion DC platform built around UPS backup architecture.
A 219.24 kWh liquid-cooled sodium-ion cabinet operating across 216-504 Vdc for data-center and critical-power UPS projects.
Application fit
Start with the operating duty.
Unlike the AC cabinet and container products, this model is a DC-only battery platform. It uses 2.9 V / 175 Ah prismatic sodium-ion cells in a 3P144S arrangement and must be matched directly to the UPS charging window, discharge current, autonomy and redundancy architecture.
Open the RFQ input checklistIntegrated architecture
Four layers form the starting platform.
The commercial scope still needs a project responsibility matrix covering every external interface.
Sodium-ion cells
Prismatic 2.9 V / 175 Ah cells provide 219.24 kWh rated energy.
DC string and breaker
A 3P144S arrangement operates from 216 to 504 Vdc through the cabinet DC protection.
BMS and monitoring
Battery management, EMS monitoring, alarms and communications protect the DC system.
UPS interface
The project UPS defines charging behavior, discharge current, autonomy, redundancy and acceptance tests.
Technical specifications
Documented configuration data.
Values are taken from the supplied manufacturer specification. Final purchase, installation and acceptance must use the approved project datasheet, drawings and test documents.

Buyer questions
Resolve these points before ordering.
Use the answers to narrow the design; use the final project documents to release the order.
Does this cabinet include an inverter or PCS?
No. It is a DC battery cabinet intended to connect to an external UPS. The UPS and the battery operating window must be matched before quotation.
Can it replace an existing lead-acid UPS bank directly?
Not without an engineering review. Check the UPS charging profile, DC voltage range, discharge current, fault current, autonomy, communication and protection coordination.
How many cabinets are needed for a data center?
The quantity depends on UPS power, required runtime, permitted SOC window, redundancy topology, ageing allowance and whether each UPS block has a dedicated battery string.
Which standards apply?
The source specification references sodium-ion battery, BMS, low-voltage equipment, EMC, packaging and energy-storage standards. The required certification list must be confirmed for the installation country.
