Tigo Energy TS4-A-F SunSpec Rapid Shutdown Module adds on to your existing or new solar photovoltaic panels. For a complete TS4 platform, each solar panel in the PV system requires a TS4-A-F rapid shutdown module. Once installed in the back of your PV module, it will help you improve your energy harvesting with greater flexibility and increased control over your PV system.
The TS4-A-F (formerly TS4-R-F) provides an economical solution to comply with UL 1741, NEC 2014 and NEC 2017 rapid shutdown requirements. It is fully compatible with SMA US-41 SunSpec inverters. When paired with a Sunny Boy or Tripower inverter, the ShadeFix feature optimizes the production of each module in the string, notably when shading impacts the system performance. Tigo Energy offers a comprehensive library of technical documentation.
The TS4-A-O optimization module is part of the same family of retrofit PV kits; it is also Rapid Shut Down Certified when used with compatible SMA US-41 inverters.
