GoodWe STS Series

The Static Transfer Switch (STS) Box is a cutting-edge
switching solution designed for use in commercial and
industrial energy storage systems. This system 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-tied operation. The STS
is versatile, supporting connections with generators and
accommodating large loads such as heat pumps and
motors. During grid-tied operation, the STS supports a
maximum load capacity of 138kW (200A) for the backup
interface. This robust solution ensures continuous and
reliable power supply, offering flexibility and efficiency in
energy management.
