Our energy system offers bi-directional flow, allowing for both discharging from the battery to the DC grid and charging from the DC grid to the battery. With fully automatic protection functions, including overheating, overload, short circuit, and overcurrent, our system ensures safety and reliability.
Featuring original imported power devices and a fully digital circuit design, our system utilizes industrial-grade chips that can operate in extreme environments, including cold, high temperature, and humid conditions. The main circuit incorporates a DSP chip from TI of America, Infineon IGBT module, and Infineon movement for driving and protection.
Our system's output is automatically synchronized with the grid, resulting in low current harmonic content and no pollution or impact on the grid. The grid-connected current is controllable and adjustable through closed-loop control. With a wide input voltage range, our system is suitable for various occasions.
Equipped with a comprehensive power protection scheme and self-test and protection functions, our system ensures reliable operation. In case of system failure, it will automatically stop working. The compact circuit structure ensures maximum efficiency of at least 96%.
Customizable protection levels are available to meet specific user needs. Additionally, our system provides an Ethernet interface and supports the standard Modbus TCP communication protocol.
