Determine Number of TAP and CCA Units

Overview

The number of TAPs and CCAs needed for a system is determined by both the number of modules and the size and layout of the installation.

Determine Number of TAPs

• The maximum number of TS4 units per TAP is 300 (when using the TS4-R-Duo, max number of panels per TAP is 600).
• The maximum number of TAPs per CCA is 7.
• The maximum number of TS4 units per CCA when using TAP is 900 (when using the TS4-R-Duo, max number of panels per CCA is 1,800).
• A TAP can communicate with UHD-Core TS4s that are within a maximum line-of-sight radius (no obstructions) of 115ft (35m). If there are TS4 units more than 115ft (35m) away from the TAP, use more than one TAP.

Determine the Number of CCA (Cloud Connect Advanced) Units

All modules in the same string must be assigned to the same CCA.

All strings on the same string inverter must be assigned to the same CCA.

Cloud Connect Advanced is available as a kit for indoor or outdoor use, refer to the Select Your Cloud Connect Unit article to choose the kit that fits your project.
