Tigo TAP is required for rapid shutdown and Tigo CCA is required for monitoring with TS4-A-O.

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, and 2020.
