Contact us to arrange your order.



Optimisation function is available as an integrated module junction box (TS4-O) or as an add-on/retro-fit unit (TS4-A-O). Suitable for design using unequal string lengths, mixed orientations, or areas of mismatch and can be installed in shaded areas with a reduced setback ratio.

Go for full deployment with Module-Level Monitoring & Safety on every panel by installing the CCA kit


Optimise only where needed, with selective deployment.

  • Shade and mismatch tolerance
  • Maximised roof usage
  • Greater design flexibility
  • Enhanced energy yield
  • Plus all the benefits of Safety and Monitoring when used with CCA Kit with TAP

Rapid shutdown with monitoring accessories

Cca outdoor & indoor kits

The CCA Indoor Kit includes one CCA and TAP.

The CCA Outdoor Kit includes one CCA, one TAP, and an IP68-rated outdoor enclosure.

Mount the CCA on the included DIN rail with plenty of room to spare for cables and even a revenue-grade AC meter.

Cloud connect advanced (cca)

One of the smallest solar data loggers on the planet.

Tigo’s Cloud Connect Advanced (CCA) enables valuable insight into module and system data for real-time analysis. The CCA is part of Tigo’s SMART communication platform which is supported by allmajor inverter manufacturers worldwide.

  • Enables immediate access to system data for installers and end users
  • Enables internet connection via Ethernet or ZigBee Wi-Fi
  • Optional cellular connectivity for remote locations
  • Connect up to 900 TS4 units
  • Connect up to seven TAP units per CCA
  • Configure and commission with Tigo SMART app
  • Monitor 3rd party devices via Modbus

This UL-certified Rapid Shutdown solution works with almost all modules & inverters to comply with NEC 2014, 2017, and 2020.

Tigo access point (tap)

Tigo access point (tap)

Seamless data management and communication with Tigo Smart modules and retrofit devices.

The Tigo Access Point (TAP) significantly improves the level of security at module-level deactivation thanks to its utilisation of wireless mesh technology.

Place the TAP on the back of one of the modules within the array. The TAP will communicate wirelessly with every TS4 unit within a 35 meter radius.

  • Communicate directly with up to 300 TS4 units
  • Wireless mesh communication
  • Easily clips to the module frame without tools

Ts4-f fire safety rapid shutdown accessories

Rapid shutdown system (rss)

Rss transmitter

Tigo’s RSS Transmitter completes the cost-effective RSS architecture when paired with Tigo’s Fire Safety solutions – including the TS4-F (integrated), TS4-A-F (add-on) and TS4-A-2F (add-on for two modules) units.

The RSS Transmitter sends a signal to the TS4-F units to keep PV modules connected while powered on and supplying energy. TS4-F units automatically enter rapid shutdown mode when the RSS Transmitter is switched off and resume energy production when power is restored to the RSS Transmitter. This solution complies with NEC 2014, 2017, and 2020 690.12 specifications utilizing power-line communication (PLC). Highlights of the RSS Transmitter include:

  • Module-level deactivation with automatic or manual shutdown
  • Available for integrated and retrofitted/add-on PV installations
  • Easy installation, no commissioning process is required
  • Compatible with many UL-listed residential & commercial inverters
  • Compatible with SunSpec signalling
Rss signal detector

Tigo skill with amazon alexa

Tigo customers receive the benefits of Amazon’s Alexa™ technology available on Amazon’s Echo™ and other Alexa-enabled products when monitoring their PV systems. This “Tigo skill” integration allows English- and German-speaking Tigo customers to use their voice to inquire about the production or other information about their PV system collected by Tigo’s SMART website. Tigo residential and commercial customers with monitored solar arrays can talk to Alexa, the cloud-based voice service by Amazon, using the Tigo skill which responds with context-aware actions. For example, simply saying “Alexa, ask Tigo how much my PV system produced today,” can report a day’s worth of power without the need to log in to Tigo’s SMART website. Other voice commands include: Alexa, ask Tigo.

  • what is my [Daily/Monthly/Yearly] Production Summary?
  • what is my System Total Production Summary?
  • what is my [Average/Peak] Energy Production?
  • what is an optimiser?
  • tell me about Tigo.
