TS4-R Module Technology

TS4-R Module Technology

Optimization redefined.

With this innovative DC technology from SMA,
for the first time, a system’s individual PV modules
can be selectively optimized, easily and cost-effectively.

Highest energy yields - Lowest costs

The TS4 modular platform is a unique plug-and-play concept that enables customized functionality with a simple exchange of a cover featuring integrated power electronics. Functionality increases from Diodes to Long Strings, with each cover including new benefits in addition to the functionality of the preceding cover. The TS4 is available in module integrated versions from leading suppliers and retrofit models available exclusively from SMA.

Progressive Functionality - TS4-R Module Technology

Traditional Module-level Power Electronics

Traditional Module-level Power Electronics

Existing microinvertrer and DC optimizer systems require additional electronics on every module, regardless of whether they are actually needed. This leads to:

  • More time on the roof
  • Longer installs
  • Greater failure risk

Power+ Selective Deployment

Power+ Selective Deployment

SMA’s Power+ Solution can be applied to every module but, unlike other solutions, can also be selectively deployed to address specific needs, for example, shading. Installing power electronics on only the affected modules results in:

  • Faster installation
  • A more cost-effective design
  • Reduced service risk

Fast and easy installation

No DC optimizer or microinverter technology is as simple or fast to install at the TS4-R platform. can be applied to address project specific needs such as:

  • Optimization for complex roof structures and partial shading
  • Shutdown code requirements
  • Module-level monitoring


With TS4-R, installers can benefit from significant time savings compared to other DC optimizer and microinverter technologies. With no additional tools, the TS4-R solution can be quickly and easily mounted to a module in the warehouse or directly on the construction site. This simplifies logistics and reduces installation time.

  • Save up to 90 minutes on a fully-optimized residential system
  • Save an additional 72 minutes when using selective deployment
