The New 1,000-V Generation

Huawei JUPT-HD1

Utility Smart Substation

More Power at the Same Current

With the new JUPT-HD1 Smart Transformer Station, Huawei utilizes a system voltage of 1,000 V, thereby laying the foundation for the efficient design of modern utility-scale PV systems.

The higher system voltage enables greater power output at the same current and with the same cable cross-section. This allows for more efficient design of power transmission and system architecture.

The JUPT-HD1 is also optimized for the requirements of modern PV modules and the latest Huawei Utility-Scale inverters.

The Huawei Integrated System

From modules to medium voltage—everything is perfectly coordinated

The substation is only one part of the overall system. It delivers its full benefits when working in conjunction with the other components of the Huawei solution.

 

From the PV modules and utility-scale inverters to the substation and digital monitoring, all components are designed to work together seamlessly.

 

This offers advantages in:

  • System Compatibility: Coordinated components reduce the number of interfaces and simplify system planning.

  • Efficient Project Planning: The inverter and substation can be considered and designed as a single integrated system.

  • Digital Asset Management: The components can be integrated into the Huawei system’s digital monitoring and management capabilities.

  • Scalability: The system design can be adapted to different plant sizes and project requirements.

  • Procurement: Through WATTKRAFT, you can source all the necessary system components from a single supplier.

Partnership

Technical support from planning through implementation

WATTKRAFT supports you with all technical questions regarding the substation and its integration into the overall project.

Our services include:

  • Technical Consulting
  • Selection of the appropriate substation
  • Design tailored to the system concept for larger projects
  • Coordination with the inverters used
  • Support with grid connection requirements
  • Interface Coordination
  • Support with implementation

 

In doing so, we do not view the substation in isolation, but rather as an integral part of the overall system design.
