2.5MW 10kV Transformer-Isolated Containerized Energy Storage Power Conversion System
2.5MW 10kV Containerized Energy Storage Power Conversion System.
This containerized power conversion unit provides 2500kW rated DC-side power across a 1000–1500V operating voltage range and a 2500kVA AC-side interface rated at 10kV. Transformer isolation, battery communication and dispatch communication interfaces are specified for integration within an energy storage project.
Check the Main Electrical Interfaces First
For a MW-class energy storage project, selecting the power conversion equipment begins with electrical compatibility rather than battery energy capacity alone. The battery-side DC voltage, required conversion power and AC grid interface all need to match the project architecture.
2.5MW Power Conversion Between High-Voltage DC and 10kV AC
The DC side is rated at 2500kW with a maximum current of 2619A. On the AC side, rated output power is specified at 2500kVA with a rated voltage of 10kV.
The specified AC-side power factor is adjustable from -1 to +1, while maximum total harmonic distortion is listed as no more than 3% at rated power.

Communication Interfaces for System Integration
The specification separates battery-side communication from dispatch communication, allowing the power conversion unit to exchange information with compatible battery equipment and project-level control systems.
Container Size Matters at 2.5MW
Electrical compatibility is only one part of project selection. The physical container measures 5523 × 2400 × 2800mm and has an approximate net weight of 15 tonnes.
These values should be considered when planning the available installation area and equipment handling requirements. The specified operating temperature range is -25°C to +50°C, with a working altitude of up to 2000m.
Air-Cooled Power Conversion Configuration
Air cooling is specified as the cooling method for this configuration. Although the source document carries a general liquid-cooling product heading, the individual technical parameter for this model explicitly lists air cooling.
Frequently Asked Questions
Is a 2.5MW 10kV energy storage PCS suitable for my project?
Suitability depends on the required conversion power, battery-side DC voltage and AC grid connection. This configuration is rated at 2500kW on the DC side, operates within a 1000–1500V DC range and provides a 10kV AC interface. These values should be checked against the electrical architecture of the project.
Can this 2.5MW energy storage system connect directly to a 10kV network?
The AC side is specified at 2500kVA with a rated voltage of 10kV and transformer isolation. Final connection design should still be confirmed according to the project's grid requirements and electrical design.
What battery voltage is required for a 2.5MW energy storage PCS?
The specified DC operating voltage range is 1000V to 1500V, with a maximum DC current of 2619A. The battery system should be configured so that its operating voltage remains within these limits.
Does this 2.5MW system include batteries and a fixed MWh capacity?
The technical parameter sheet does not specify a fixed battery capacity in kWh or MWh. This product is defined by its power conversion, DC input and 10kV AC-side parameters, so the battery configuration should be confirmed separately according to the project requirements.
Can the 2.5MW PCS communicate with an EMS or power dispatch system?
Yes. Dispatch communication interfaces include Modbus RTU, Modbus TCP and IEC 60870-5-104. Battery-side communication interfaces include CAN and RS485. Final compatibility should be checked against the project's control platform.
How do I choose between 1.25MW, 1.725MW and 2.5MW energy storage PCS configurations?
The main difference is rated power capacity. The appropriate configuration should be selected according to the project's required power, battery DC architecture, 10kV AC-side requirements, installation space and overall system design rather than choosing by power rating alone.
What space and site conditions are required for the 2.5MW container?
The equipment dimensions are 5523 × 2400 × 2800mm with an approximate net weight of 15 tonnes. The specified operating temperature range is -25°C to +50°C and the working altitude is up to 2000m. These values should be considered during site planning.
What information should I send when requesting a 2.5MW energy storage solution?
Provide the required system power, battery-side DC voltage range, AC grid voltage, communication requirements, site temperature, altitude and available installation space. If the battery system has already been selected, its DC voltage and current information should also be provided for compatibility checking.
Check Whether the 2.5MW Power Block Matches Your Project
Provide your required power, battery-side DC voltage, AC grid voltage, communication requirements and site conditions. The 2.5MW / 10kV configuration can then be evaluated against your project parameters.
