Description
【Descriptions】
The grid-connected/off-grid switching STS module adopts seamless switching technology using static switches, supporting seamless switching between grid-connected and off-grid modes. It is designed with DSP and supports CAN/RS485 communication. This module is widely used in applications that require grid-connected/off-grid switching, such as weak power grid areas and microgrid energy storage, to ensure uninterrupted power supply to critical loads.
【Advantages】
Three-phase five-wire system (3W+N+PE), supporting off-grid unbalanced loads. When combined with the PCS module, it can achieve seamless switching between grid-connected and off-grid modes, ensuring uninterrupted power supply to critical loads. Module design for easy installation and maintenance. Module height is only 2U, compact structure, and high power density.
【Application 】
Weak power grid areas, microgrid energy storage. In applications such as weak power grid areas and microgrid energy storage, when the grid is available, power can flow bidirectionally between the battery and the grid, allowing for charging and discharging functions, peak shaving, and earning electricity price differences. When the grid experiences a power outage, the grid-connected/off-grid switching STS module switches to battery power to ensure uninterrupted power supply to the loads.
