Long-duration containerized BESS
1.725 MW / 5.016 MWh Container BESSFive megawatt-hours configured for energy-led dispatch.
A 12-string, 5.016 MWh LFP container matched with a 1.725 MW PCS stage for approximately 2.91 hours of rated duration.
Application fit
Start with the operating duty.
This configuration uses twelve 314 Ah LFP strings to deliver 5.016 MWh at 1331.2 V nominal DC. A 1.725 MW PCS stage creates a nearly three-hour rated platform for projects where energy duration is prioritized over maximum short-window power.

Four layers form the starting platform.
The commercial scope still needs a project responsibility matrix covering every external interface.
Battery strings
Twelve LFP strings arranged as 12P416S provide 5.016 MWh rated energy.
DC collection
String-level protection and high-voltage collection feed a common PCS interface.
PCS and MV boundary
A 1.725 MW, 690 V PCS stage is coordinated with the project step-up design.
Container systems
BMS, EMS, liquid cooling, fire protection and communications support plant operation.

Buyer questions
Resolve these points before ordering.
Use the answers to narrow the design; use the final project documents to release the order.
Why choose 1.725 MW instead of 2.5 MW for the same energy?
The 1.725 MW version provides a lower C-rate and about 2.91 hours of rated duration, which suits energy-led dispatch. The 2.5 MW version targets higher power and roughly two-hour duty.
Can this system support frequency services?
PCS and EMS capability must be matched to the grid code, response-time requirement, SOC management strategy and warranty duty cycle before frequency-service claims are confirmed.
Does the listed weight include the step-up transformer?
The approximate 44 t figure refers to the documented battery container. Confirm PCS, transformer and switchgear weights separately in the project equipment schedule.
What determines the final site footprint?
The equipment envelope, service corridors, fire separation, transformer and switchgear locations, cable trenches, turning radius and crane outriggers all affect the final layout.
