Tigo Energy TS4-A-O Module Add-On RSD Unit, Optimization, 451-00252-32

Note: Cloud Connect Advanced (CCA) and TAP (Gateway) required for rapid shutdown with TS4-A-O

The TS4-A-O (Optimization) is the advanced add-on/retrofit optimization solution that brings smart module functionality to standard PV modules for higher reliability. Improve energy efficiency by upgrading underperforming PV systems or adding smart features to new installations.

The TS4-A-O with UHD-Core technology and expanded specifications supports PV modules up to 500W.


  • Module-level optimization for increased energy yield and greater design flexibility
  • Enhanced safety for NEC 690.12 rapid shutdown compliance
  • Module-level monitoring for energy production tracking and system
  • PV array enters rapid shutdown in event of AC grid loss
  • Sealed housing, no longer a removable cover (will cut down on installation error and installer induced failures)
  • Smaller form/fit - fits flush with most module frames
  • Simplified retrofit attachment mechanism - removal of frame clips allows for hardware installation for alternate mounting locations
  • Power rating increased to 500W
  • Wider voltage window
  • Standardized on 1.2M cable length (for landscape orientations)
