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.

Our selection of original imported power devices, along with fully digital circuit design and industrial-grade chips, ensures optimal performance even 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.

With automatic synchronization to the grid, our system maintains low current harmonic content, ensuring no pollution or impact on the grid. The closed-loop control of grid-connected current allows for easy controllability and adjustability. The wide input voltage range makes our system suitable for various occasions.

Our system boasts an all-round power protection scheme and perfect self-test and protection function. In case of system failure, it will automatically stop working. The compact circuit structure ensures maximum efficiency of at least 96%. Additionally, the protection level can be customized according to your needs.

For seamless communication, our product provides an Ethernet interface and supports the standard Modbus TCP communication protocol.
