Module-level PV Optimizer

Optimization is a Flex MLPE function available as an integrated modular junction box base (TS4-O) or as an add-on unit (TS4-A-O). Design using unequal string lengths, mixed orientations, or areas of mismatch. Install in shaded areas with a reduced setback ratio. In addition to optimization, the TS4-A-O enables module level monitoring, and rapid shutdown in compliance with NEC 2014, 2017, 2020.

  • Optimization
  • Monitoring
  • Rapid Shutdown
Features and benefits
  • Suitable for up to 700W solar modules
  • The higher performance optimizer with Predictive IV Technology (PIV)
  • The ONLY optimizer with selective deployment
  • Includes the benefits of Safety & Monitoring
  • Meets US NEC rapid shutdown requirements
  • Optimizes right out of the box
  • Shade and age tolerance to maximize lifetime yield
  • Works wirelessly with the TAP & CCA

The TS4-A-O (Optimization) is the advanced add-on 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 complies with NEC 2017 and 2020 690.12 Rapid Shutdown specifications when installed on
each module and accompanied by the Tigo Access Point (TAP) and the Cloud Connect Advanced
(CCA). Module-level DC production data, as well as data from other Modbus connected devices, can
be analyzed via Tigo’s Energy Intelligence Software when connected to the cloud.

The TS4-A-O with UHD-Core technology and expanded specifications supports PV modules up to 700W, and 15A.
