Tigo TS4-X-O | Optimization, Monitoring & Rapid Shutdown

The Tigo TS4-X-O is a next-generation module-level power electronics (MLPE) solution that combines optimization, monitoring, and rapid shutdown in a single device. Built for high-power PV modules up to 800W, it supports up to 25A (Isc) and 20A (Imp), helping installers increase energy production while reducing the effects of mismatch and shade.

Unlike one-size-fits-all optimizer architectures, the TS4-X-O can be selectively deployed in the right system designs, allowing installers to target only the modules affected by shade, mismatch, or complex roof layouts. This helps reduce unnecessary hardware costs while improving overall system flexibility and performance.

Using Tigo’s Predictive IV and impedance-matching technologies, the TS4-X-O helps each module operate at its best possible power point in real-world conditions. It also provides module-level visibility and supports rapid shutdown when used within the appropriate Tigo system architecture.

Note: For monitoring and full TS4-X-O communications functionality, the Tigo Cloud Connect Advanced (CCA) and Tigo Access Point (TAP) are required.

Key Features & Benefits
