Product Description

Jinan Deming Power Equipment Co., Ltd

Introducing our innovative energy solution:

Features:

• Bi-directional energy flow: Our system enables energy discharge from the battery side to the DC grid or charge from the DC grid side to the battery.


• Fully automatic protection functions: Overheating, overload, short circuit, overcurrent, and more are all safeguarded.


• Original imported power devices: We use high-quality components for reliable performance.


• Fully digital circuit design: Our advanced technology ensures efficiency and precision.


• Industrial-grade chips: All our chips are designed to operate normally in challenging environmental conditions, including cold, high temperature, and humidity.


• Safe and reliable: We utilize a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection.


• Grid-friendly output: Our system automatically synchronizes with the grid, with low current harmonic content and no pollution or impact on the grid.


• Controllable and adjustable: Our system features closed-loop control of grid connected current for precise management.


• Wide input voltage range: Suitable for various occasions and applications.


• All-round power protection: Our system incorporates a comprehensive protection scheme and self-test function, ensuring reliable operation.


• Compact circuit structure: The design is space-efficient and maximizes efficiency, with a minimum of 96% efficiency.


• Customizable protection level: Tailor the system to meet your specific needs.


• Ethernet interface and Modbus TCP communication protocol: Our system provides easy connectivity and integration.
