The Static Transfer Switch (STS) is a cutting-edge switching solution designed for commercial and industrial energy storage systems, with STS138 kW paired with ET 50 kW and STS125 kW paired with ET 100 kW,and the STS138 and STS125 feature different exterior designs. It enables precise control of inverters, allowing seamless transitions between grid-tied and off-grid modes. In the event of a grid outage, the inverter seamlessly switches to off-grid mode, providing power to critical loads through solar panels or batteries. When grid power is restored, the inverter smoothly transitions back to grid-connected operation. The STS is versatile, supporting connections with generators and accommodating large loads such as heat pumps and motors. This robust solution ensures continuous and reliable power supply, offering flexibility and efficiency in energy management.
