TS4-R Module-Technology

Highest energy yields - Lowest costs

The TS4-R module system is a cost-effective system that fits into any PV module design, making it the right solution for every application. With the TS4-R platform, for the first time, every PV module can now be flexibly equipped with an additional function. Only the modules affected by energy yield loss are equipped/fitted with TS4-R This means energy yields can be strategically increased and system costs reduced.

Existing DC optimizer systems

Existing DC optimizer systems

  • All modules always have to be equipped with an optimizer, whether necessary or not
  • This quickly leads to unnecessarily high costs

SMA solution

SMA and Tigo solution

  • Only affected modules (e.g., in case of partial shading) have to be equipped with an optimizer
  • Lower investment costs
  • Lower installation costs

Fast and easy implementation


According to individual requirements, the TS4-R platform offers the corresponding functions:

  • Complete module-level monitoring
  • Module-level shutdown
  • Optimization for complex roof structure and partial shading


With TS4-R, you and your customers only pay for the function actually needed.

With no additional tools, the TS4-R solution can be quickly and easily mounted to a module already in the warehouse or directly on the construction site. This makes logistics easier and reduces installation time.

If the system is to be monitored or shut down, you will need the Cloud Connect Advanced communication unit which is available separately.
