Tigo Access Point (TAP)
The TAP is the bridge between the TS4 devices on the roof and the Cloud Connect Advanced sitting near the service panel. The TS4-A-O and TS4-A-S devices emit module-level telemetry over the PV wire, and the TAP collects that signal wirelessly and passes it along to the CCA. From there it goes up to Tigo's Energy Intelligence platform, where you can see each module's performance from a browser or the mobile app.

About this product
The TAP is the bridge between the TS4 devices on the roof and the Cloud Connect Advanced sitting near the service panel. The TS4-A-O and TS4-A-S devices emit module-level telemetry over the PV wire, and the TAP collects that signal wirelessly and passes it along to the CCA. From there it goes up to Tigo's Energy Intelligence platform, where you can see each module's performance from a browser or the mobile app.
One TAP supports a few hundred TS4 devices, enough for most residential and light commercial arrays. Place it within range of the array, with a clean line of sight where possible. For larger commercial arrays, multiple TAPs can mesh together to extend coverage.
A pure rapid-shutdown install with only TS4-A-F devices doesn't need a TAP, only the RSS Transmitter side of the system. The TAP is the monitoring side. Powered over PoE from the CCA.

Tigo Cloud Connect Advanced
The CCA is the gateway that ties a Tigo monitoring install to the internet. It sits in or near your service panel, talks to the TAP on the array side, and pushes telemetry up to Tigo's Energy Intelligence platform over your home or shop network. If you're running TS4-A-O optimizers or TS4-A-S monitoring devices, the CCA is what gets that per-module data off the roof and into the monitoring platform where you can see it. From the EI app you'll get module-level voltage, current, power, and temperature, with historical data and per-module alerts when something drifts. The CCA also handles inverter integration for compatible models, so it can pull AC-side data and present a full system picture without a second app. Ethernet primary, Wi-Fi backup. Powers the TAP over PoE. A rapid-shutdown-only install (TS4-A-F + RSS Transmitter) doesn't need a CCA. It's only on the menu when you've picked monitoring or optimization TS4 devices. UL listed.

Tigo RSS Transmitter - Single Core
The RSS Transmitter is what makes a TS4-A-F actually shut down. It sits on the DC line out of the array, between the panels and the inverter, and sends a constant low-voltage signal over the PV wire. While the signal is there, every TS4 on the roof stays in its conducting state. When the AC side trips, the signal stops, and within 10 seconds every module's output drops to the safe level NEC 690.12 requires. This is the single-core version, which means it watches one DC string at a time. Pure Signal is Tigo's name for the keep-alive signaling protocol. It's PLC, runs at low voltage, and doesn't interfere with the array's normal operation. You need this transmitter on the install if your inverter doesn't already carry integrated Tigo RSS. EG4's FlexBOSS, GridBOSS, 12kPV, and 18kPV families have it built in, so they talk to the TS4 directly without a separate box. Most older string inverters need a transmitter wired in. Sold individually. Mounts in the rapid shutdown disconnect or the DC combiner. UL listed.

Tigo RSS Transmitter Kit - Dual Core
The Tigo RSS Transmitter is the device that triggers rapid shutdown on a solar array, sending a signal down the PV wires to the TS4 units on each module so the system drops to a safe voltage when power is cut. This dual core kit uses Tigo’s Pure Signal technology, which lets several transmitters work off one coordinated signal on bigger systems. It is outdoor rated and meets NEC 690.12 for the 2014, 2017, and 2020 codes.
