Tigo Energy TS4-A-O Optimization Module


SKU: TS4-A-O Category:

Order requirement

TS4 modules are sold in packages only. A package must include a minimum of 10 TS4 units or an SMA inverter

Tigo Energy 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.



SMA America

SMA America is a pioneer in photovoltaics power conversion, they started in 1981 in Germany. Today they are a top 3 inverter manufacturer worldwide with presence in 15 different countries including the United States and Canada. In 2011 they opened the solar academy in California to help installers understand SMA’s technology and bring that knowledge to the home of thousand of homeowners in the US. SMA staples are the Sunny Island inverters for off-grid and remote applications and the Sunny Boy inverters for residential and small commercial applications. In recent years they added the Tripower line of commercial inverters ranging from 12kW to 30kW per unit. Some of their inverters are assembled in Colorado and qualify for the ARRA recovery act. All their units are UL listed and comply with the most recent requirements in the National Electric Code (NEC). Additionally SMA provides their Sunny Portal free of charge to SMA users. It is one of the most advanced energy communication platforms; all SMA inverters can transfer production data to the Sunny Portal. The portal is accessible to system owners via the Internet, where they can view and monitor their system’s performance in great detail. SMA America has raised the bar in the solar industry for over 30 years and they certainly will continue to do so.
