Our energy system offers bi-directional flow, allowing for 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, you can trust in the safety and reliability of our product.
Featuring a selection of original imported power devices and a fully digital circuit design, our system ensures optimal performance. All chips are industrial grade, capable of operating in cold, high temperature, and humid environments.
The main circuit incorporates a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection. This combination guarantees a secure and reliable operation. Additionally, our system provides automatic synchronization with the grid, low current harmonic content, and no pollution or impact on the grid.
With closed loop control of grid connected current, our system offers controllable and adjustable output. It also boasts a wide input voltage range, making it suitable for various occasions.
Our system is equipped with 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 ensures maximum efficiency of at least 96%.
Customizable protection levels cater to your specific needs, and the Ethernet interface and standard Modbus TCP communication protocol provide seamless connectivity.
