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 charge from the DC grid side to the battery.
With fully automatic protection functions, including overheating, overload, short circuit, and overcurrent, our power equipment ensures safe and worry-free operation. We have carefully selected original imported power devices and implemented a fully digital circuit design to guarantee superior performance.
All our chips are industrial grade, capable of operating normally in cold, high temperature, and humid environments. The main circuit features a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection, providing a safe and reliable solution.
Our system offers automatic synchronization 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 precise and adjustable power management.
With a wide input voltage range, our power equipment is suitable for various occasions. It incorporates a comprehensive power protection scheme and perfect self-test and protection functions. In the event of a system failure, it will automatically stop working to prevent any further issues.
The compact circuit structure ensures space efficiency, while the maximum efficiency of ≥ 96% guarantees optimal performance. Additionally, the protection level can be customized according to the user's specific needs.
For seamless connectivity and control, our power equipment provides an Ethernet interface and supports the standard Modbus TCP communication protocol.
Choose Jinan Deming Power Equipment Co., Ltd for reliable, efficient, and technologically advanced power solutions.
