The low-carbon future of cities is never just a slogan, but a profound transformation in how buildings consume and manage energy.
While many office buildings still rely heavily on conventional grid power and high-energy consumption operation models, a quiet energy revolution is unfolding in Shanghai’s Lingang New Area.
Here, a landmark building has been created—the China MCC Lingang Headquarters Building (hereinafter referred to as “MCC Group”), the first regional benchmark building truly achieving zero-energy consumption and zero-carbon operation.
From the very beginning of its design, the building has moved beyond traditional energy logic. Instead of relying solely on energy-saving measures, it establishes a self-generated, self-consumed, and self-circulating green energy system.
As low-carbon transformation shifts from concept to implementation, PV + Energy Storage + DC Flexible Technology (PV-Storage-DC-Flexibility) has become a critical foundation for ultra-low-energy buildings.
What enables MCC Group to achieve energy autonomy and controllability?
The answer lies in the core equipment supporting the building’s green energy dispatch system.
As a benchmark zero-energy office building in Lingang New Area, MCC Group adopts a multi-port GCEVO Power Router standard platform, implementing an innovative PV + Storage + DC Flexible energy solution. This establishes a safe, reliable, intelligent, efficient, and low-carbon DC microgrid system, providing the technological foundation for autonomous green energy supply, flexible energy consumption, and precise carbon management.
PV + Storage + DC Flexible System Architecture
The MCC Group project is built on a 750V DC bus architecture, forming an integrated green energy supply system.
It seamlessly integrates multiple energy sources, including solar power, grid electricity, and lithium battery storage, while flexibly supporting various DC loads and multi-voltage requirements, enabling efficient energy interconnection across all scenarios.
Multi-Port Power Router Configuration
The system is equipped with a multi-port PV-Storage-DC Flexible Power Router, featuring:
- Grid port: 200 kW
- PV port: 20 kW
- Energy storage port: 150 kW
- 120 kW unidirectional 750V DC charging pile
- 7 kW bidirectional V2G charging pile
- 60 kW 375V DC load
This configuration covers the full energy lifecycle, including:
- Power generation
- Energy storage
- Load consumption
- Grid interaction
- Vehicle-to-grid (V2G) interaction
It enables a new paradigm for zero-carbon building energy systems.
Energy Management and System Integration
As the control and dispatch center, the Power Router is further integrated with:
- Four 150 kW / 320 kWh energy storage systems already deployed in the park
- A 510 kW photovoltaic AC grid-connected system
- The upper-level EMS (Energy Management System) of the building owner
The system receives control instructions from the upper EMS while uploading all real-time operational data, enabling full hierarchical energy coordination and digital management.
Engineering Design and Deployment
The system layout is designed with both practicality and maintenance efficiency in mind:
- Indoor wall-mounted Power Router installation
- Outdoor standardized energy storage cabinet deployment
- Cable entry/exit from the top with front-side maintenance access
This significantly improves operational and maintenance efficiency.
Charging piles are connected to the grid platform, and the entire system is installed in the basement of the building. It is equipped with 4G communication modules and reserved RJ45 interfaces, enabling remote intelligent monitoring and control.
This ensures more efficient and convenient energy dispatch, fully supporting the smart office requirements of the headquarters base.
Performance and Demonstration Value
The MCC Group PV + Storage + DC Flexible project transforms technical standards into real zero-carbon performance.
From multi-source energy supply to intelligent dispatching, from precise carbon measurement to flexible response implementation, every parameter reflects strong technical capability, and every design detail aligns with the vision of green and low-carbon development.
The project not only establishes a solid zero-carbon energy foundation for MCC Group, but also sets a benchmark for the application of PV + Storage + DC Flexible technologies in Lingang New Area.
It provides a replicable and scalable model for the low-carbon transformation of modern buildings, offering a practical reference for future zero-carbon building development worldwide.
