The energy storage inverter by Jinan Deming Power Equipment Co., Ltd allows for bi-directional energy flow, enabling discharge from the battery side to the DC grid or charging from the DC grid side to the battery. With fully automatic protection functions for overheating, overload, short circuit, and overcurrent, this inverter ensures safe and reliable operation.
Featuring a fully digital circuit design and industrial-grade chips, this energy storage inverter can operate normally in extreme environmental conditions such as cold, high temperature, and humidity. The main circuit is equipped with a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection, ensuring optimal performance.
The output of this inverter is automatically synchronized with the grid, resulting in low current harmonic content and no pollution or impact on the grid. The grid connected current is controlled and adjustable through closed loop control. With a wide input voltage range, this inverter is suitable for various occasions.
For added safety and convenience, this energy storage inverter is equipped with a comprehensive power protection scheme, self-test, and protection function. In case of system failure, it will automatically stop working. The compact circuit structure ensures maximum efficiency of ≥ 96%.
Customizable protection levels and the provision of an Ethernet interface with standard Modbus TCP communication protocol make this energy storage inverter a versatile and user-friendly solution.
