Against the backdrop of the carbon neutrality era, CHISAGE ESS is actively supporting the development of green energy. The company has successfully completed three major zero-carbon renovation demonstration projects at the Ningbo Administrative Service Center: the “Zero Carbon Garden,” the “Photovoltaic Curtain Wall,” and the “Photovoltaic Storage and Direct Current Flexibility (PV-Storage-DC Flex) Project.”
Zero Carbon Garden
The project is located on the east side of the Ningbo Municipal People’s Government Science and Technology Bureau. It utilizes the independently developed CE48100-W lithium battery pack and Jup-5G1-LE low-voltage single-phase hybrid inverter by CHISAGE ESS, along with lightweight monocrystalline 430Wp solar panels. This combination creates an eco-friendly, efficient, and intelligent green energy solution that achieves the goal of self-generation and self-consumption.
During the daytime when there is ample sunlight, the photovoltaic system prioritizes supplying power to the data display and other loads, with any excess electricity stored in the battery. Once the battery is fully charged, the surplus energy can be fed back to the grid. When sunlight is insufficient or during nighttime, the battery primarily supplies power to the data display and other loads. In extreme situations where the power is still insufficient, the grid provides appropriate supplementary power.
Photovoltaic Curtain Wall
The “photovoltaic curtain wall” project is located at Building 4 of the Administrative Service Center, with an actual installation area of 46.71m² and an installed capacity of 3.72kWp. This effectively enhances the building’s own power generation capacity. The design of the photovoltaic curtain wall is not only aesthetically pleasing but also provides green energy for the daily operations of the Administrative Service Center.
The “PV-Storage-DC Flex ”Project is located on the southeast side of Building 4, with nine outdoor parking spaces to the east and three outdoor parking spaces to the south, adjacent to the basement staircase passage. To effectively utilize space and improve efficiency, the overall construction plan features a single-column design placed at the rear of the parking spaces, with a 9-meter interval. The photovoltaic canopy uses a cantilevered structure. This allows for construction within the parking spaces while maximizing the protection of the existing greenery.
The renovation features CHISAGE ESS’s 60kW photovoltaic storage integrated machine, 60kW DC/DC charging pile, and 120kWh Container ESS. Through the optimized configuration and scientific design of each component, it offers users highly efficient, eco-friendly, quiet, and low-consumption integrated energy storage and charging services.
Safe and Reliable
- Intelligent air-cooled ultra-quiet design, fan speed is adjusted accordingly with load and temperature changes.
- The heat dissipation design of hot and cold air duct isolation avoids the control circuit from working under high temperature.
Efficient and Convenient
- The overall structure adopts modular combination, which is convenient for installation, maintenance and expansion.
- All-in-one cabinet type housing, maintenance and installation are all implemented by the outer door opening, faster and safer.
Multi-function Machine
- On-demand capacity increase function: the system can be connected to the lithium battery system, the battery power output and utility power output at the same time, through the dynamic expansion of the system to solve the load instantaneous overcapacity.
- Peak shaving and valley filling: the system realizes the profit of the difference between peak and valley electricity price, helping users to reduce the cost of electricity consumption.
- DC fast charging, super charging: flexible charging improves the utilization rate of charging power and meets the charging power demand of electric vehicles.
- Vehicle battery detection function: real-time detection of battery status information during the charging process, in-depth analysis of the battery health status, to provide safe and controllable charging management.
The successful landing of the photovoltaic storage demonstration project in Ningbo Administrative Service Center has provided a replicable and scalable model for the realization of urban low-carbon development, and CHISAGE ESS will continue to actively contribute to the green transformation and work with all parties to create a sustainable future.
