Tigo Energy TS4-R-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-R-F 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-R-F (formerly TS4-R-S) 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.
