SMA TS4-R-S Module Retrofit Kit

The TS4 modular platform allows you to retrofit existing SMA inverters with module-level power electronics, providing the capability for module-level monitoring and shade mitigation. The TS4-R Module Retrofit Kits are easy to install and offer an immediate boost to system performance, with the unique option of selective deployment allowing you to install optimizers only where needed. The TS4-R works with any standard module and can be attached to the frame on the ground or prior to the site visit.

The TS4-R-S kit adds rapid shutdown capability and module-level monitoring, it does not include optimization capabilities. Check out the TS4-R-O optimizer if you require optimization for improved energy yield and shade tolerance.

About SMA

Key Points:

  • Offers a wide range of inverters to suit most any solar panel or system.
  • Forefront of Inverter technology.

Founded in 1981, SMA Solar Technologies is headquartered in Niestetal, Germany, and has a worldwide presence in 15 different countries including the United States and Canada.

SMA touts themselves as the world's largest producer of solar inverters and monitoring systems for photovoltaic applications. With a wide range of inverters, they have one for every module type and power class including grid-tied, offgrid, or backup applications. Wholesale Solar designs their UL listed Solar Sky Gridtie Systems with SMA SunnyBoy inverters.

While SMA inverters are designed in Germany, the Sunny Central, the Sunny Island, and SMA SunnyBoy inverters in the 3 kW to 7 kW range are assembled in their new plant in Denver, Colorado. These inverters qualify for the ARRA recovery act and are UL and cUL listed.

Continually pushing the envelope when it comes to technology, SMA launched its own SMA solar academy in Rocklin, California, in April 2011. Their Solar Academy is equipped with the latest high-tech teaching tools and demonstration inverters to complement its comprehensive range of courses on photovoltaics and SMA products.
