Tigo Energy Cloud Connect Advanced (CCA) Kit with TAP monitoring device. The Tigo Energy Cloud Connect acts as a hub. It controls optimisation, provides safety features, and enables module-level monitoring via the Tigo cloud.

To add monitoring and safety, first, you usually add the Optimiser cover or Retro-fit Optimiser to each panel. Then you install the CCA (Cloud Connect Advanced) and TAP.

The CCA is wired to the AC power and connects to the internet router via Wifi or direct connection with a data cable.

The TAP goes on the roof in the middle of the array and is wired to the CCA with a Cat5/RS-485 cable. This should be an outdoor Cat5/RS-485, which is UV-resistant to prevent any weather damage. The TAP communicates wirelessly with each Optimiser and you setup the system using the Tigo mobile app.

If the system is very big, is split over more than one roof (like an east-west system) or there are any physical barriers between the panels, you would need additional TAPs. When you use additional TAPs they are wired one to another using the Cat5/RS-485 cable. Most small residential systems use one TAP if all the panels are together on the roof.

Each TAP supports up to 300 Optimisers within 35 meters with no physical barriers.

Each CCA supports up to 7 TAPs with a maximum of 900 Optimisers per CCA.

If you have more than 900 Optimisers, you can just add more CCA.
