The Tigo Automatic Transfer Switch (ATS) is a required component for Tigo EI Residential Solar Solutions, enabling safe and automatic transitions between grid power and backup power during outages. When utility power is lost, the ATS quickly switches your home to solar and battery power, helping keep critical loads or entire homes powered without manual intervention. Once grid power is restored, the system automatically returns to normal operation. Designed for reliability, ease of installation, and intelligent monitoring, the Tigo ATS is an essential part of a complete Tigo energy storage solution.
