Tigo TS4-R-O-DUO 700W Dual Module Optimization Add-on Unit

700W Dual-Module Solar Power Optimizer

The Tigo TS4-R-O-DUO is a 700W dual-module add-on power optimizer engineered to maximize energy harvesting in residential and commercial photovoltaic systems. Designed to service two solar panels simultaneously, this unit mitigates mismatch losses caused by shading, soiling, or uneven roof tilts while enabling module-level rapid shutdown compliance when paired with Tigo gateway equipment.

By providing Maximum Power Point Tracking (MPPT) across connected module pairs, the optimizer prevents performance drops in shaded panels from pulling down the output of adjacent series-connected solar strings. Its IP65/IP67 weather-resistant casing mounts directly to panel racking or module frames, streamlining on-site installation for array upgrades.
