Tigo TS4‑A‑O Optimiser: The Smart Solar Add-On for Safer, Stronger PV Performance

The Tigo TS4‑A‑O is a powerful module-level optimiser designed to improve energy yield, add panel-level monitoring, and ensure compliance with rapid shutdown regulations. With plug-and-play installation and broad inverter compatibility, it’s a flexible upgrade path for residential and commercial solar systems.

Boost Panel Output with Shade Tolerance

One shaded panel can drag down your entire array, but with the TS4‑A‑O, smart power electronics ensure each module performs independently. This improves yields in partially shaded conditions, such as homes with chimneys, roof obstructions or mature trees nearby.

Installers can target underperforming panels without overhauling the system, giving homeowners greater ROI and peace of mind.

Real-Time Monitoring for Every Module

When paired with a Tigo Cloud Connect Advanced (CCA), this optimiser enables live panel-level monitoring and performance diagnostics via the Tigo Energy Intelligence platform. That means better fault detection, easier maintenance, and more satisfied clients.

• Track voltage, current and temperature per module
• Receive alerts if a panel drops below expected performance
• Use data insights to support system guarantees

Universal Inverter Compatibility

The TS4‑A‑O works with virtually all string inverters and hybrid units, making it a go-to optimiser for both retrofit and new installations. It’s certified for 700 W panels and supports up to 15 A input current, futureproofed for the latest high-output modules.
