Flex MLPE - TS4 Platform

TS4 with cover open

TS4-B                                                                                                                                 TS4-R

The TS4 universal platform enables you to choose the exact options you need for any given project or customer, from safety features to module-level diagnostics and maximized energy harvest. The TS4-B and TS4-R universal baseplates can be matched with one of several TS4 covers containing the application electronics. Together they form a new generation of junction boxes; the Flex MLPE; flexible, replaceable, and upgradeable, accompanied by a powerful PV 2.0 communication-centric architecture backend.

Long Strings

The TS4-L is the complete smart module solution. It is ideal for systems requiring fully optimized performance at the module level, as well as monitoring, safety, and longer strings. Fewer BOS components allow for faster installation and reduced SKU management.

  • String length increased by up to 30%
  • Inverter optimization
  • Fewer BOS components
  • Lower wire-losses
  • Faster installation
  • Plus all the benefits of Optimization, Safety and Monitoring


The TS4-O bundles the Tigo smart module features into one seamless unit for enhanced energy yield and increased design flexibility. TS4-O is ideal for roofs which are challenged by shading, but do not need longer strings. In addition to safety, monitoring, and PV 2.0 synchronization, TS4-O optimizes each module when shade drops their performance. With optimized modules, more roof space can be used to maximize energy production.

  • Shade and age tolerance
  • Maximized roof usage
  • Enhanced energy yield
  • Plus all the benefits of Safety and Monitoring
  • Greater design flexibility


For installations unencumbered by shading, the TS4-S provides the necessary safety and monitoring services to ensure your systems meet local fire regulations, while also providing you and your customers increased insight into system performance.

  • NEC 690.12 rapid shutdown compliant
  • Over-temperature protection
  • Module-level deactivation
  • Plus all the benefits of Monitoring
  • Automatic or manual shutdown



Predicting and conducting maintenance on solar installations is critical to ensuring that they last beyond their expected 25 year life. With a window into a system's performance through module-level monitoring, solar fleets can maximize system up-time and identify performance issues before they become serious problems. The TS4-M enables continuous system-wide monitoring for fleets to aid in customer support and ongoing operations and maintenance.

  • Reduced O&M costs
  • CRM integration
  • PV-2.0 data synchronization
  • Warranty tracking
  • Module bar code tracking
  • Team management
  • Fleet management


The TS4-D is the building block of the TS4 family and Tigo's smart solution. With diodes embedded in the cover of the junction box, this basic system enables OEMs to standardize on the TS4 baseplate for both conventional and smart modules.

  • Similar to a standard junction box
  • Field replaceable and upgradeable
  • Standardization on basic TS4 baseplate
  • Heat dissipation away from the module
  • Applicable to conventional and smart modules
