GoodWe STS200-80-10 Static Transfer Switch 50kVA

The GoodWe STS200-80-10 is an automatic transfer switch designed for GoodWe ET series hybrid inverters, enabling seamless backup power during grid outages. When a power failure occurs, the system automatically switches from grid operation to backup mode via the inverter and connected battery system, ensuring stable and reliable power supply for residential and small commercial installations.

The STS box supports continuity of critical loads and increases overall system reliability. Thanks to very short transfer times, the installation is instantly disconnected from the public grid and switched to backup power. The compact and robust IP65-rated enclosure is designed for safe indoor installation and complies with relevant grid disconnection requirements. It integrates easily into existing GoodWe ET systems.
