Tigo TS4-A-2F Dual Module MLPE | Rapid Shutdown Solution

Estimated to ship early November

The Tigo TS4-A-2F is a cost-effective rapid shutdown device (RSD) engineered for module-level safety and NEC 2017/2020 compliance. Designed to control two PV modules per unit, the TS4-A-2F helps installers save time and reduce costs by minimizing wiring complexity—offering up to 16% fewer connections on a 14-panel string compared to single-channel MLPE devices.

Backed by IEC and UL certifications and UL PVRSS compliance with the industry’s widest network of inverters, this rapid shutdown unit ensures global acceptance and seamless integration. Many inverter brands already feature built-in RSS transmitters, allowing for plug-and-play PLC communication that simplifies and accelerates installation.

Key Features & Benefits

• Dual-Module Connection – One MLPE supports 2 solar panels per unit, reducing labor, hardware, and system costs.

• High Power Capacity – Handles up to 1000W (500W per channel), 16–80V, and 15A per channel, suitable for today’s high-power PV modules.

• Certified & Compliant – Meets NEC 2017/2020 rapid shutdown requirements, IEC & UL certified, and UL PVRSS listed.

• Wide Inverter Compatibility – Approved with hundreds of inverters for maximum design flexibility.

• Fast Plug-and-Play Setup – Communicates via PLC with inverters that include integrated RSS transmitters, reducing installation time.

• Installer-Friendly Design – Snaps directly onto the module frame with no grounding wire required.

• Standard MC4 Connectors – Streamlined integration with common PV connectors.
