General requirements
1、Standardized and modular design.
- Flexible stackable deployment to meet different solar power generation requirements in various capacities and locations.
- Compact structure, integrated configuration, plug-and-play design for rapid implementation of smart zero-carbon upgrades in industrial parks.
2、High reliability and high safety.
- The brand of medium and low-voltage cabinets and prefabricated enclosure is consistent, ensuring integrated integration.
- Meets the requirements for use in harsh environments, with the enclosure being corrosion-resistant and thermally insulated. It is sturdy and reliable, and the steel structure can meet the requirements for C5-VH high salt-mist environmental use.
- Can be equipped with fire alarms and video surveillance systems to ensure a high level of security in the operating environment.
3、Comfortable and safe walk-in prefabricated substations.
- Reserved space suitable for equipment operation and office space for personnel.
- The substation is insulated and fireproof, using rock wool boards with a thickness of no less than 50mm, which are A1-grade non-combustible. The floor thickness is no less than 6mm.
- Indoor temperature is maintained between 0-35°C to ensure stable equipment operation and a comfortable working environment for personnel.
Case 1 : 2-12MW New Energy Distribution Module Solution

Distributed photovoltaic installation has a compact coverage area, making cable installation convenient and cost-effective. The site is limited, not suitable for new construction or expanding distribution stations. Suitable for a walk-in working environment. | Distributed photovoltaic installations have a wide coverage area, and sometimes cables need to be laid over long distances, leading to potential construction difficulties. The main station is well-suited for walk-in work environments.
| Flexible stacking deployment of main and sub-stations according to photovoltaic installation needs. Distributed photovoltaic installations cover a wide range, or cable laying is too long. Main station is suitable for walk-in work environments. |
