Product Description

Jinan Deming Power Equipment Co., Ltd

Our product offers a bi-directional energy flow, allowing for discharging from the battery side to the DC grid or charging from the DC grid side to the battery. This flexibility ensures efficient energy management.

For your safety and convenience, our product features fully automatic protection functions, including protection against overheating, overload, short circuit, and overcurrent.

We only use original imported power devices, ensuring the highest quality and performance.

The fully digital circuit design, along with industrial-grade chips, allows our product to operate normally in cold, high temperature, and humid environments, making it suitable for various conditions.

The main circuit of our product is equipped with a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection. This guarantees the safety and reliability of the system.

Our product's output is automatically synchronized with the grid, resulting in low current harmonic content and no pollution or impact on the grid.

With closed loop control of grid connected current, our product offers controllable and adjustable power output.

The wide input voltage range makes our product suitable for a wide range of applications.

Our system provides comprehensive power protection and self-test functions. In the event of a system failure, it will automatically stop working, ensuring safety and preventing further damage.

The compact circuit structure of our product maximizes efficiency, with a maximum efficiency of ≥ 96%.

Customizable protection levels allow you to tailor the product to your specific needs.

In addition, our product provides an Ethernet interface and supports the standard Modbus TCP communication protocol, ensuring easy integration into your existing network infrastructure.
