Tigo TS4‑A‑O Optimization Module – 725 W, 22 A, MC4

The Tigo TS4‑A‑O is a module‑level optimizer that combines optimization, monitoring, and rapid shutdown, tailored for high‑power PV systems. Key specifications and benefits include:

• Supports up to 725 W per module (UL), or 700 W (IEC), with a maximum input current of 22 A and maximum voltage up to ~80 V per module

• Features Predictive IV (PIV) Technology for enhanced energy harvesting in shaded or mismatched conditions

• Supports NEC 2014/2017/2020 compliant rapid shutdown when used with Tigo RSS transmitter or TAP + CCA

• Selective deployment allows you to optimize only the PV modules that need it—ideal for mixed orientations or string lengths

• Installation is fast and tool‑free: 10‑second, no-bolt frame mounting, with no additional ground wiring needed

• Communicates wirelessly with TAP & CCA, fully compatible with Tigo EI monitoring platform for module‑level data visibility

• Backward-compatible across the entire TS4‑A‑O product line and includes 25‑year warranty

Ideal for PV installations with shading, multiple orientations, or high‑wattage modules, the TS4‑A‑O maximizes system yield while ensuring code-compliant safety.
