In today's society, the shift to renewable energy sources poses significant challenges for ensuring consistent energy supply. This is driven not only by the massive energy demand but also by government objectives to lower carbon emissions. Consequently, there is an increasing demand for energy storage solutions. A power conversion system (PCS) plays a pivotal role in any efficient energy storage system (ESS), acting as a bridge between direct current (DC) batteries and the electrical grid.
Our Three-Phase Power Conversion System is designed for commercial use, offering reliable and efficient power conversion services to meet the dual requirements of modern power needs and environmental protection.
Commercial and Industrial Facilities: Suitable for large-scale electricity users in commercial and industrial settings, helping businesses reduce power costs and improve energy efficiency.
Renewable Energy Plants: Serves as a core component in renewable energy plants like solar and wind farms, enhancing energy conversion efficiency.
Grid Support Services: Provides grid stability support, such as frequency regulation and backup power, enhancing grid reliability and flexibility.
AI intelligent cloud management
Through the use of intelligent cloud platform for multi-dimensional management, energy storage converters can achieve ubiquitous access to equipment, big data analysis, energy management, intelligent evaluation and other functions. This cloud management capability enables the energy storage system to achieve more refined intelligent control and optimization. Energy storage converters combined with big data analysis capabilities can achieve real-time monitoring of battery status, fault prediction, health status assessment and life prediction. Through deep mining and analysis of operating data, the energy storage converter can further improve the performance and reliability of the system. The energy storage converter can realize real-time adjustment and optimization of power grid load through intelligent scheduling and energy consumption management. During the peak load period, the energy storage converter can release energy to reduce the pressure of the grid. In the low load period, the excess electric energy can be stored to achieve the effect of peak cutting and valley filling.
Flexibly adapted to multiple scenarios
Modular design is an important feature of PCS, which supports the expansion and upgrade of the system. Users can add or subtract modules as needed to adapt to changing energy needs. This design not only improves the scalability of the system, but also reduces the cost of maintenance and upgrade. PCS is suitable for a variety of application scenarios, including but not limited to user-side energy storage, grid-side energy storage, microgrids, data centers, electric vehicle charging stations, etc. Whether it is the need for high power short-term charge and discharge, or the need for long-term stable power supply scenarios, we can provide effective solutions.
Multiple security
The energy storage converter adopts advanced core-level safety management technology and realizes multi-point safety protection by combining software and hardware. This design can respond quickly when the battery is abnormal, cut off the risk, and ensure the safe and stable operation of the entire battery system. Through accurate data control and operation management, the energy storage converter can effectively extend the service life of the battery. This involves not only the daily maintenance and monitoring of the battery, but also the optimization of the battery charging and discharging strategy to reduce the stress and loss of the battery.
