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

The Tigo TS4-A-O is a versatile module-level power electronics (MLPE) solution that delivers optimization, monitoring, and NEC-compliant rapid shutdown for PV systems. Supporting up to 22A (Isc), 725W modules, and 1500V UL/1000V IEC, this optimizer enhances energy harvest, system visibility, and safety across residential, commercial, and utility-scale solar projects.

Unlike traditional optimizers, the TS4-A-O offers selective deployment—allowing installers to optimize only the modules that need it, such as shaded areas or mixed orientations. This reduces unnecessary costs while improving design flexibility and overall system performance.

⚠️ Note: The Tigo TAP is required for rapid shutdown communication, and the Tigo CCA (Cloud Connect Advanced) is required for module-level monitoring.

Key Features & Benefits

• High Module Compatibility – Supports modules up to 700–725W, ideal for today’s larger PV panels.

• Advanced Optimization – Powered by Predictive IV (PIV) Technology, delivering maximum power in real-world conditions.

• Selective Deployment – Use optimizers only where needed, cutting hardware and labor costs.

• Built-In Safety & Monitoring – Enables real-time module-level monitoring while ensuring NEC 2014/2017/2020 rapid shutdown compliance.

• Instant Optimization – Works right out of the box with no special setup.

• Shade & Age Tolerance – Maintains high performance even under mismatch, shading, or module degradation.

• Seamless Connectivity – Wirelessly integrates with Tigo TAP & CCA for easy commissioning and monitoring.
