Home – Project Detail
The STS module for grid-connected/off-grid switching employs static switch seamless switching technology, enabling uninterrupted transitions between grid-connected and off-grid modes. It features a DSP-based design and supports CAN/RS485 communication. This module finds extensive applications in scenarios requiring grid-connected/off-grid switching, such as weak grid areas and microgrid energy storage, ensuring continuous power supply to critical loads.
In application scenarios like weak grid areas and microgrid energy storage, when the grid is powered on, power flows bidirectionally between the battery and the grid, enabling charging/discharging functions, peak shaving, and valley filling to capitalize on electricity price differentials. In the event of a grid outage, the grid-connected/off-grid switching STS module switches to battery power, ensuring uninterrupted load
