Product Description:
Introducing the cutting-edge power solution from Jinan Deming Power Equipment Co., Ltd. Our advanced energy system offers a range of features designed to meet the needs of English-speaking natives. With bi-directional energy flow, our system allows for efficient discharge from the battery side to the DC grid or charging from the DC grid side to the battery.
Experience peace of mind with our fully automatic protection functions, including overheating, overload, short circuit, and overcurrent safeguards. We prioritize safety by selecting original imported power devices and utilizing a fully digital circuit design. Our industrial-grade chips ensure reliable operation in cold, high temperature, and humid environments.
The heart of our system lies in the main circuit, which features a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection. This combination guarantees a safe and reliable performance. Additionally, our system automatically synchronizes its output with the grid, resulting in low current harmonic content and no pollution or impact on the grid.
Enjoy the flexibility of closed loop control of grid connected current, allowing for easy adjustability. Our system boasts a wide input voltage range, making it suitable for various occasions. With a comprehensive power protection scheme and self-test and protection function, our system ensures uninterrupted operation. In case of system failure, it will automatically stop working.
Designed with efficiency in mind, our compact circuit structure achieves a maximum efficiency of ≥ 96%. Furthermore, the protection level can be customized according to your specific needs. For seamless integration and communication, our system provides an Ethernet interface and supports the standard Modbus TCP communication protocol.
