| High Light | 1.25MW Energy Storage Container ，10kV AC-Side Energy Storage Unit ，Transformer-Isolated Energy Storage System | ||
1.25MW 10kV AC-Side Transformer-Isolated Energy Storage Container.
This AC-side containerized energy storage unit is rated at 1250kW on the DC side and 1250kVA on the AC side, with a DC operating voltage range of 1000–1500V and rated AC voltage of 10kV. The system uses transformer isolation and provides battery and dispatch communication interfaces for energy storage project integration.
The electrical parameters define the unit as the AC-side conversion interface of an energy storage project. The DC side operates across a 1000–1500V voltage range with 1250kW rated output power, while the AC side is rated at 1250kVA and 10kV.
With a rated AC voltage of 10kV, the unit is intended for energy storage projects requiring a medium-voltage AC interface. Rated AC current is 72.5A, while the specified power factor is adjustable from -1 to +1.
The parameter sheet also specifies total harmonic distortion of no more than 3% at rated power.

Two communication layers are specified for system integration. CAN and RS485 are provided as battery communication interfaces, while the dispatch communication interfaces include Modbus RTU, Modbus TCP and IEC 60870-5-104.
The specified operating temperature range is -25°C to +50°C, with storage temperatures from -25°C to +55°C. Operating relative humidity is specified at 0% to 95%, and the nominal working altitude is up to 2000m.
The container dimensions are 5523 × 2400 × 2800mm with an approximate net weight of 6 tonnes. Air cooling is specified as the cooling method.
The AC side is rated at 10kV with a rated output of 1250kVA and rated AC current of 72.5A. Final grid connection design should be checked against the electrical requirements of the specific project.
The specified DC operating voltage range is 1000V to 1500V. The DC-side rated output power is 1250kW and the maximum DC current is 1309A.
The technical parameter sheet defines this product by its DC-side input, power conversion, transformer isolation and 10kV AC output. Battery energy capacity in kWh is not specified, so the battery configuration should be confirmed separately according to the project requirements.
Yes. Transformer isolation is specified in the technical parameters, with the AC side rated at 10kV.
CAN and RS485 are specified for battery communication, allowing communication with compatible battery-side equipment according to the project integration design.
The specified dispatch communication interfaces include Modbus RTU, Modbus TCP and IEC 60870-5-104. Compatibility with the project's EMS or dispatch platform should be confirmed during system integration.
The specified operating temperature range is -25°C to +50°C, with a working altitude of up to 2000m. The container measures 5523 × 2400 × 2800mm and has an approximate net weight of 6 tonnes, which should be considered during site planning.
Key information should include the required power, battery-side DC voltage range, AC grid voltage, communication requirements, site temperature, altitude and available installation space. These values can then be compared with the system specifications before confirming the project configuration.
Send us your required power, DC voltage range, AC grid voltage, communication requirements and site operating conditions. The technical configuration can then be checked against your project requirements.
