Jinan Deming Power Equipment Co., Ltd offers a high-quality energy solution that caters to the needs of both discharging and charging energy. Our product features a bi-directional energy flow, allowing it to 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, our product ensures maximum safety. We prioritize the use of original imported power devices and employ a fully digital circuit design. All the chips used in our product are industrial grade and can operate normally in cold, high temperature, and humid environments.
The main circuit of our product incorporates a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection, guaranteeing a safe and reliable performance. The output is automatically synchronized with the grid, resulting in low current harmonic content and no pollution or impact on the grid.
Our product offers closed-loop control of grid-connected current, allowing for controllable and adjustable output. It also boasts a wide input voltage range, making it suitable for various occasions. The system includes an all-round power protection scheme and a perfect self-test and protection function. In the event of a system failure, it will automatically stop working.
The compact circuit structure of our product ensures maximum efficiency, with a rating of ≥ 96%. Additionally, the protection level can be customized according to the user's needs. For added convenience, we provide an Ethernet interface and support the standard Modbus TCP communication protocol.
Choose Jinan Deming Power Equipment Co., Ltd for a reliable and efficient energy solution that meets your needs. Experience the benefits of our advanced technology and superior performance.
