For systems with TS4, a Cloud Connect Advanced (CCA) and TAP/Gateway are only required for data logging or rapid shutdown. If monitoring and rapid shutdown are not desired, TS4-O and TS4-L can be installed without a CCA/TAP and still provide optimization (and longer strings if using TS4-L.)
| Product | CCA and TAP required? |
| ES series optimizer (ES50, ES75, ES110, ES170) |
Yes |
| 2ES series dual optimizer (2ES50, 2ES75) |
Yes |
| JES series smart module junction box | Yes |
| TS4-D (cell-string diodes only) | No |
| TS4-M (monitoring) | Yes |
| TS4-S (safety) | Yes |
| TS4-O (optimization) | Only for monitoring or rapid shutdown |
| TS4-L (long strings) | Only for monitoring or rapid shutdown |
