Tigo TS4-X-O – Module-Level Optimization, Monitoring, and Rapid Shutdown for High-Power Solar Arrays

At Solar&Solar, we’re always looking to showcase advanced technologies that improve solar performance, safety, and efficiency. The Tigo TS4-X-O is one such innovation — delivering module-level optimization, monitoring, and rapid shutdown for PV modules up to 800 W. Designed for the latest high-power, high-current solar panels, this MLPE (Module Level Power Electronics) solution is ideal for both new installations and retrofits.

Optimized for Maximum Energy Output

Tigo’s patented technology ensures each solar module produces as much power as possible, even when shading or mismatch occurs. By minimizing performance losses across the array, the TS4-X-O increases system yield and helps you achieve a faster return on investment.

Full Module-Level Monitoring

With Tigo Energy Intelligence and the required Tigo Access Point (TAP) and Cloud Connect Advanced (CCA), the TS4-X-O provides complete visibility of both module- and system-level production. This allows installers and operators to identify and resolve issues quickly, reducing downtime and maintenance costs.

Built-In Safety with Rapid Shutdown

The TS4-X-O is a UL Standards-certified component for photovoltaic rapid shutdown systems (PVRSS) worldwide. It features multi-factor rapid shutdown capability for enhanced safety when paired with the optional Tigo RSS Transmitter. This ensures compliance with global safety regulations while protecting both systems and people.
