Product Description
Jinan Deming Power Equipment Co., Ltd - Product Description
Our energy system offers bi-directional flow, allowing for discharge from the battery side to the DC grid or charge from the DC grid side to the battery. With fully automatic protection functions for overheating, overload, short circuit, overcurrent, and more, you can trust in the safety and reliability of our product.
Featuring a selection of original imported power devices and a fully digital circuit design, our system ensures optimal performance. All the chips used are industrial grade and can operate normally in cold, high temperature, and humid environments.
The main circuit of our system incorporates 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 operation. Additionally, the output is automatically synchronized with the grid, resulting in low current harmonic content and no pollution or impact on the grid.
Our system also offers closed-loop control of grid-connected current, allowing for easy controllability and adjustability. With a wide input voltage range, it is suitable for various occasions. Furthermore, it provides an all-round power protection scheme and perfect self-test and protection functions. In the event of a system failure, it will automatically stop working.
The compact circuit structure ensures efficiency, with a maximum efficiency of ≥ 96%. The protection level can be customized according to your specific needs. Additionally, we provide an Ethernet interface and support the standard Modbus TCP communication protocol for seamless connectivity.
