The DC Grid Energy System from Jinan Deming Power Equipment Co., Ltd is a cutting-edge solution for efficient energy flow. With bi-directional capability, it allows for both discharging from the battery side to the DC grid and charging from the DC grid side to the battery. This flexibility ensures optimal energy management.
This system boasts a range of fully automatic protection functions, including overheating, overload, short circuit, and overcurrent protection. By using original imported power devices, it guarantees top-notch performance and reliability.
The fully digital circuit design, along with industrial-grade chips, enables seamless operation even in challenging environments, such as cold, high temperature, and humid conditions.
Featuring a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement, the main circuit of this system ensures safe and reliable driving and protection. The output is automatically synchronized with the grid, resulting in low current harmonic content and no pollution or impact on the grid.
The closed-loop control of grid-connected current allows for easy controllability and adjustability. Moreover, the wide input voltage range makes it suitable for various occasions.
With a comprehensive power protection scheme and self-test and protection function, this system guarantees uninterrupted operation. In the event of a system failure, it will automatically stop working.
The compact circuit structure ensures maximum efficiency of ≥ 96%. Additionally, the protection level can be customized according to the user's needs. The system also provides an Ethernet interface and supports the standard Modbus TCP communication protocol for seamless integration into existing networks.
