Monitor and protect every module

TS4-A-S delivers per-module production visibility through Tigo's Energy Intelligence platform while shutting down each module independently within 30 seconds of AC grid loss.

Open, inverter-agnostic design

Fully compatible with thousands of inverter models from more than 50 brands, and works with system voltages up to 1000/1500 V for maximum design flexibility and easy retrofits.

Built for rooftops

An IP68 / NEMA 3R enclosure withstands heat, cold, dust, and driving rain across an operating range of -40 to 75 °C. Wireless communications simplify commissioning and enable reliable ongoing monitoring.

Installer-friendly

Compact hardware snaps onto the module frame or mounts to racking, with clearly labeled MC4/EVO2 connectors and 99.6% maximum efficiency so there's no performance penalty.
