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 utilizes industrial-grade chips that can operate in extreme environments. The main circuit incorporates a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection.
Our system ensures low current harmonic content and no pollution or impact on the grid. With closed loop control of grid connected current, it is controllable and adjustable. The wide input voltage range makes it suitable for various occasions.
With a compact circuit structure and a maximum efficiency of ≥ 96%, our system provides all-round power protection and perfect self-test and protection functions. In case of system failure, it will automatically stop working.
Customizable protection levels and the inclusion of an Ethernet interface with standard Modbus TCP communication protocol further enhance the versatility and connectivity of our product.
