Product Description

Product Description

Introducing the advanced and reliable power equipment from Jinan Deming Power Equipment Co., Ltd. Our cutting-edge technology ensures efficient energy flow in both directions, allowing for seamless discharging from the battery side to the DC grid or charging from the DC grid side to the battery.

With fully automatic protection functions, including overheating, overload, short circuit, and overcurrent, our power equipment guarantees the safety of your operations. We have carefully selected original imported power devices and implemented a fully digital circuit design to ensure top-notch performance.

All our chips are industrial grade, capable of functioning flawlessly 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, providing a safe and reliable solution.

Our power equipment is designed to synchronize its output with the grid, resulting in low current harmonic content and no pollution or impact on the grid. The closed-loop control of grid-connected current allows for precise and adjustable operation.

Thanks to its wide input voltage range, our system is suitable for various occasions. It also incorporates an all-round power protection scheme and perfect self-test and protection function. In the event of a system failure, it will automatically stop working.

The compact circuit structure ensures space efficiency, while the maximum efficiency of ≥ 96% guarantees optimal energy utilization. Additionally, the protection level can be customized according to your specific needs.

To facilitate communication and control, our power equipment provides an Ethernet interface and supports the standard Modbus TCP communication protocol.
