Tigo TS4-A-O 700W Retrofit Frame-Mounted Solar Panel Optimiser Optimises individual PV modules to help reduce the impact of module mismatch and partial shading. Retrofit-friendly design: snaps to a standard solar-panel frame, with removable clips for rail or rack mounting. Supports PV modules up to 700W and 15A, with optional Tigo monitoring and module-level rapid shutdown functionality. Tigo TS4-A-O 700W optimiser The Tigo TS4-A-O 700W Retrofit Frame-Mounted Optimiser adds module-level optimisation to a standard solar panel. It is a practical option for new arrays and upgrades where panels face different orientations, intermittent shade or electrical mismatch. By fitting an optimiser to each affected module, the system can operate with greater design flexibility than a conventional unoptimised string. The unit mounts directly to the module frame or, with its clips removed, to the mounting rack. It uses wireless communication and can be commissioned using an Android or iOS mobile device. For module-level monitoring, pair the TS4-A-O with a Tigo Access Point (TAP) and Cloud Connect Advanced (CCA). Key features Module-level optimisation for PV modules rated up to 700W. 15A maximum continuous input current and 80V maximum input voltage. Frame-mounted installation with removable clips for alternative rack mounting. Wireless communications for compatible Tigo monitoring and system management. When installed on every module with a Tigo TAP and CCA, supports compliance with NEC 2017 and 2020 690.12 rapid shutdown requirements. Where to use Use the Tigo TS4-A-O 700W solar panel optimiser on string-based PV systems where one or more modules may perform differently from the rest of the array. Typical applications include commercial rooftops with plant-room shadows, warehouse arrays split across roof aspects, agricultural buildings, and retrofit projects with ageing or mixed-performance modules. It can also suit new solar installations where module-level visibility or a future-ready path to Tigo monitoring is required. TAP and CCA equipment are required for module-level shutdown, while the CCA is required for monitoring with the TS4-A-O.
