Introducing the advanced energy management system from Jinan Deming Power Equipment Co., Ltd. Our system offers bi-directional energy flow, allowing for efficient discharge from the battery side to the DC grid or charging from the DC grid side to the battery.
With fully automatic protection functions, our system ensures safety and reliability by offering overheating, overload, short circuit, and overcurrent protection. The selection of original imported power devices and fully digital circuit design further enhances the system's performance.
Our system is designed to operate in various environmental conditions, thanks to the use of industrial-grade chips that can function normally in cold, high temperature, and humid environments. The main circuit incorporates a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection, ensuring optimal performance.
When connected to the grid, our system automatically synchronizes the output, resulting in low current harmonic content and no pollution or impact on the grid. The closed-loop control of grid-connected current allows for precise and adjustable power management.
Featuring a wide input voltage range, our system is suitable for different occasions and provides all-round power protection with a perfect self-test and protection function. In case of system failure, it will stop working to prevent any further damage.
The compact circuit structure ensures maximum efficiency of ≥ 96%. Additionally, the protection level can be customized according to the user's needs, providing flexibility and tailored solutions.
For seamless integration and communication, our system offers an Ethernet interface and follows the standard Modbus TCP communication protocol.
