Tigo TS4-A-F PV Optimizer with Rapid Shutdown (20A, 1500V, MC4)

The Tigo Energy TS4-A-F Module-Level Rapid Shutdown Device brings smart module functionality and rapid shutdown compliance to standard PV modules. Designed for today's high-power and bifacial modules (up to 25A Isc / 20A Imp), it installs quickly on the frame or racking and works with most string inverters.

• 700 W max output power; rated for high-current bifacial panels
• Module-level rapid shutdown compliant with NEC 2017, 2020, and 2023 (690.12)
• Automatic shutdown in <30 seconds on AC grid loss
• UL 1741 PVRSE/PVRSS certified; tested with hundreds of inverter models
• Power-line communications (PLC) signaling over existing PV conductors
• Easy install: snaps to module frame or mounts to racking; MC4 or EVO2 connectors
• IP68 / NEMA 3R outdoor rating; -40 to 85 °C operating range
• Requires Tigo RSS Transmitter or inverter with built-in Tigo certified transmitter
• 25-year warranty

Safety at every module

TS4-A-F shuts down each module independently within 30 seconds of AC grid loss, keeping installers, firefighters, and occupants safe in any emergency.

Built for high-current modules

With support for up to 25A Isc / 20A Imp, the TS4-A-F is fully compatible with today's bifacial and high-power panels, and works with system voltages up to 1000/1500 V.

Built for rooftops

An IP68 / NEMA 3R enclosure withstands heat, cold, dust, and driving rain across an operating range of -40 to 85 °C. PLC communications over PV conductors means no extra wiring.

Installer-friendly

Compact hardware snaps onto the module frame or mounts to racking, with clearly labeled MC4/EVO2 connectors and 99.9% maximum efficiency so there's no performance penalty.
