Introducing the advanced and reliable power equipment from Jinan Deming Power Equipment Co., Ltd. Our energy flow system offers bi-directional capabilities, 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 guarding against overheating, overload, short circuit, and overcurrent. The selection of original imported power devices and fully digital circuit design further enhances the performance and durability of our product.
Our industrial-grade chips are designed to operate seamlessly in cold, high temperature, and humid environments, making our system suitable for various conditions. The main circuit incorporates top-of-the-line components, including a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection.
By automatically synchronizing the output with the grid, our system minimizes current harmonic content, ensuring 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 versatile and adaptable to different occasions. With a comprehensive power protection scheme and self-test and protection functions, our system guarantees uninterrupted operation. In case of system failure, it will automatically stop working to prevent further damage.
The compact circuit structure ensures space efficiency, while the maximum efficiency of ≥ 96% optimizes energy utilization. Additionally, the protection level can be customized according to the user's needs, providing tailored solutions.
For seamless integration and communication, our system offers an Ethernet interface and supports the standard Modbus TCP communication protocol.
