Tigo Energy / SMA TS4-A-O Optimization 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-O optimization 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.
SMA designed the TS4-A-O (formerly TS4-R-O) module for enhanced energy yield and increased design flexibility. 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.
The TS4-A-O optimization module is Rapid Shut Down Certified when used with compatible SMA US-41 inverters.
