Dual-string high-capacity C&I cabinet
250 kW / 522.5 kWh Battery Storage CabinetContainer-class energy density without leaving the cabinet format.
A dual-string, dual-PCS outdoor LFP cabinet delivering 250 kW and 522.5 kWh for larger commercial loads and longer dispatch windows.
Application fit
Start with the operating duty.
The 250 kW / 522.5 kWh platform uses two 314 Ah LFP strings and two 125 kW PCS power blocks in one larger enclosure. It fills the gap between compact cabinets and centralized container systems, while maintaining a 400 V site interface.
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.
Dual battery strings
Two parallel 260-series LFP strings provide 522.5 kWh rated energy.
Dual PCS blocks
Two 125 kW bidirectional PCS units combine for 250 kW rated AC output.
Integrated controls
BMS and EMS coordinate both strings, PCS dispatch, alarms and site communication.
Outdoor platform
Liquid cooling, IP54 cabinet, C3 coating and fire suppression support C&I deployment.
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.
When should this model be selected instead of two small cabinets?
Use the 250 kW platform when a consolidated dual-string enclosure better fits the footprint, cable routing and maintenance plan. Redundancy and transport strategy should still be compared.
Can multiple units operate in parallel?
A multi-cabinet project is possible, but EMS hierarchy, metering, AC bus rating, protection, communications and transformer capacity must be engineered for the total plant.
Is 4G the only remote communication option?
No. The documented interfaces include CAN, RS485, Ethernet and 4G. The final protocol map and remote access policy are project-specific.
Does the quoted size include all external interfaces?
The 1940 x 1504 x 2555 mm figure is the base enclosure. The larger interface envelope accounts for lifting and external fire-water details.
