Seamless Grid-to-Off-Grid Transfer
50MW STS <10ms Changeover
Our PV-ESS supports both grid-tied and off-grid modes. In grid-tied mode, it optimizes energy costs. For off-grid use, it seamlessly switches during grid failures, ensuring continuous power.
A key advantage is the system’s superior off-grid transfer capability. Our 50MW STS (Static Transfer Switch) enables ultra-fast switching in less than 10 milliseconds (<10ms), guaranteeing uninterrupted power, especially for high-reliability power demands.
The system falls under the category of microgrids or distributed energy systems, commonly found in regions with poor grid stability (such as remote areas in Africa, Middle East, East South Asia). The seamless switching technology ensures.
When the grid is operational, it utilizes both photovoltaic power and the grid to reduce diesel consumption.
During grid outages, it automatically switches to the off-grid mode of the photovoltaic-diesel-battery system to ensure continuous power supply to critical loads.
It features intelligent energy dispatch, low carbon emissions, and reliable power supply.
