Description
xTigo TS4-A-O Solar Panel Optimiser | 700W | Module-Level Optimisation and Monitoring
The Tigo TS4-A-O is an add-on module-level optimiser for solar panels up to 700W. It attaches directly to the panel frame or mounts on the rack and provides optimisation, monitoring, and rapid shutdown in a single unit. Designed for both new installations and retrofit upgrades to existing PV systems. NEC 2017 and 2020 rapid shutdown compliant. MC4 compatible with 1m cable included.
Key Features
- Module-level optimisation: mitigates shading and mismatch losses across the array
- Module-level monitoring: track energy production per panel via the Tigo cloud platform
- Manual or automatic module-level rapid shutdown: NEC 2017 and 2020 compliant
- Supports PV modules up to 700W
- Rated 1500V UL / 1000V IEC
- 1m cable with MC4-compatible connectors included
- Snap-to-frame or rack mounting, no tools required
- Smart commissioning via Tigo Android or iOS mobile app
- Compatible with any inverter brand
Product Overview
The TS4-A-O is Tigo's advanced optimisation add-on that brings smart module-level functionality to standard solar panels without replacing the inverter or requiring a proprietary system. It clips directly onto the panel frame using a snap bracket (no tools needed) and connects in-line with the panel DC cable using the included MC4 connectors.
Once installed and paired with a Tigo TAP and Cloud Connect Advanced (CCA), each optimiser reports individual panel performance to the Tigo monitoring platform, making it straightforward to identify underperforming panels, shading events, and faults at module level rather than at string level.
The built-in rapid shutdown function satisfies NEC 2017 and 2020 requirements, reducing DC voltage on the roof to safe levels automatically when the inverter shuts down or manually via the app.
