Static Transfer Switch

This system enables precise control of inverters, enabling seamless transitions between grid-connected and off-grid modes. In the event of a grid failure, the inverter seamlessly switches to off-grid mode and supplies power to critical loads via solar panels or batteries.

When grid power is restored, the inverter smoothly returns to grid-connected operation. The STS is versatile and supports connections to generators and handles large loads such as heat pumps and motors. During grid-connected operation, the STS supports a maximum load capacity of 138 kW (200 A) for the backup interface.

This robust solution ensures continuous and reliable power supply, offering flexibility and efficiency in energy management.
