Overview
TS4-A with TAP and CCA Installation Manual | www.tigoenergy.com | [e-mail] 1
Overview
Tigo TS4 Flex module level power electronics (MLPE) enable monitoring, rapid shutdown, and
optimization of solar modules.
TS4-A-M (monitoring), TS4-A-S (monitoring and rapid shutdown), and TS4-A-O (monitoring,
rapid shutdown, and optimization) MLPE use the Tigo Access Point (TAP) and the Cloud
Connect Advanced (CCA) hot spot to communicate with inverters and the cloud.
This manual explains how to install TS4-A/M/O MPLE, TAPs, and the CCA. For instructions how
to install TS4-A-F/2F MPLE used with the rapid safety shutdown (RSS) transmitter, visit the Tigo
Energy Downloads page.

Safety
Tigo equipment must be installed and maintained by licensed personnel in accordance with the
National Electrical Code and ANSI/NFPA 70 wiring methods. In addition:
•Components must operate within the technical specifications listed in their datasheets.
Failure to follow instructions herein may cause equipment damage not covered by the
warranty.
•Connectors from different manufacturers cannot be mated with each other.
•Installers must wear appropriate PPE and use insulated tools.
•This product could expose the user to chemicals known to the State of California to
cause cancer. For more information refer to www.P65Warnings.ca.gov.
These safety symbols may appear in the manual:
A
hazardous situation which could result in serious injury or loss of life.
A
hazardous situation which could result in injury or damage to the product.
An important operational note.

Install TS4s
TS4-A with TAP and CCA Installation Manual | www.tigoenergy.com | [e-mail] 3
Install TS4s
•Do not install TS4s if they have been physically damaged or with damaged or
substandard wiring or connectors.
•Do not connect or disconnect TS4s under load.
•Do not apply an external voltage source to a module or string equipped with
TS4s.
TS4s mount directly onto module frames with spring clips where the frame edge extends
≥22mm/.85in and the clearance between the frame edge and the module glass is
≥30mm/1.2in. Frame thickness should be 1.8mm/.07in – 2.2mm/.085in.
If using frameless modules, remove the clips and bolt the TS4 directly to the PV rail with M8
bolts and torque to 10.2Nm. No additional grounding is required.

Install TS4s
TS4-A with TAP and CCA Installation Manual | www.tigoenergy.com | [e-mail] 4
To install a TS4:
1. Remove the QR/barcode sticker and affix it to a suitable map of the solar array.
Try to match the physical layout of modules on the roof.
2. Attach the TS4 to the top of the PV module frame using the silver clips with the cable
glands facing down. The TS4 and its cables, cable glands, and connectors must not
touch the roof surface.
3. Connect the shorter TS4 input leads to the PV modules.
You must connect the shorter TS4 input leads to the PV modules
before connecting
to
neighboring TS4s. Failure to do so can damage the TS4 units.

Install TS4s
TS4-A with TAP and CCA Installation Manual | www.tigoenergy.com | [e-mail] 5
4. Connect the longer set of TS4 output cables to the neighboring TS4 to create a string.
To disconnect a TS4:
•Activate rapid shutdown by turning off the CCA and inverter or by using the
designated PV rapid shutdown system (PVRSS) initiator.
•Wait 30 seconds after a rapid shutdown activation before disconnecting DC cables.
•Disconnect individual TS4-A output cables from a string before disconnecting the
TS4-A input cables from the module junction box.
Always assume that TS4 units are in an ON state.

Install the Tigo Access Point (TAP)
TS4-A with TAP and CCA Installation Manual | www.tigoenergy.com | [e-mail] 6
Install the Tigo Access Point (TAP)
A TAP communicates wirelessly with TS4 devices to gather monitoring data and enable rapid
shutdown. The TAP communicates with a CCA via a ferruled 4-wire communication cable such
as shielded RS-485. Refer to this Help Center article TAP and GATEWAY Communication Cable
Installation for details.
TS4-A-O MLPE used to optimize performance only and not monitoring or module level shutdown
do not require a TAP or CCA.
Complete all TAP connections before powering on the CCA.
Design Considerations
One TAP can communicate with up to 300 TS4s when placement guidelines are followed. A CCA
can communicate with up to seven TAPs and up to 900 TS4s. To calculate the number of TAPs
and CCAs required for your project, visit the Tigo Product Selection Tool.
•A TAP communicates directly with any TS4 within 10m/33ft.
•Each TS4 can relay data to and from another TS4 within 10m/33ft.
•The TAP can communicate through relays to any TS4s within 35m/115ft.
Install the TAP centrally in an array for best coverage.

Install the Tigo Access Point (TAP)
TS4-A with TAP and CCA Installation Manual | www.tigoenergy.com | [e-mail] 7
Ensure there are no obstructions that may interfere with the TAP signal to other TS4 units in
the array. If the array has multiple roof planes, you may need to install multiple TAPs. Refer to
the Help Center article TAP Placement and Layout for details.
Install Procedure
To install a TAP using a ferruled four-wire RS-485 cable:
1. Run the cable from the CCA
GATEWAY terminal to the TAP. If using more than 1 TAP
per CCA, run the cable to the first TAP in the series.
2. Connect cable wires to the left side of the TAP using either the quick-connect or the
terminal block.
3. If connecting to another TAP, use the right-side terminals after removing the pre-
installed 120Ωterminating resistor.
4. At the last TAP, leave the terminating resistor in the right-side terminal block.
5. Attach the TAP to the PV module frame using its metal mounting bracket.

Install the CCA
TS4-A with TAP and CCA Installation Manual | www.tigoenergy.com | [e-mail] 8
Install the CCA
A CCA and TAP enable monitoring and rapid shutdown. TS4-A-O MLPE used to optimize
performance only do not require a TAP or CCA.
Design Considerations
A CCA should control all TS4s on all strings connected to a specific inverter or MPPT. Install the
CCA near this inverter with access to AC power and the internet. Ethernet and WiFi are built in.
•For PV RSS compliance, the CCA must be on the same AC branch circuit as the
inverter(s) it is controlling. The rapid shutdown initiator, whether it is an automatic
disconnect or a manual switch, must turn off power to the CCA.
•One CCA can communicate with up to 7 TAPs and up to 900 TS4s.
•Make all connections to TAPs before powering on the CCA.
•The DC power supply may be a Tigo supply or a 3rd-party supply with 120/240V AC
input and 24VDC output.
A CCA also includes two three-pin RS-485 connections to enable up to 32 Modbus
communications with 3rd-party data sources such as inverters, charge controllers, revenue-
grade meters, and weather monitoring.
Install Procedure
To install a CCA:
1. Mount the CCA within a NEMA-rated enclosure that is suitable for the site environment:
indoors, minimum NEMA 1; outdoors, minimum NEMA 4.
2. Connect the TAP RS-485 wires to the CCA
GATEWAY port:

Install the CCA
TS4-A with TAP and CCA Installation Manual | www.tigoenergy.com | [e-mail] 9
3. If used, connect any 3rd-party devices using Modbus to the RS-485 1 and RS-485 2
terminals:
•All devices must have a unique Modbus address.
•Devices connected in series must have the same baud rate, parity, and stop bit
settings.
•A 120Ωresistor must connect the + and – terminals on the last Modbus device.
For a list of supported Modbus devices, refer to the Supported RS-485 Devices Help
Center article. For details about using Modbus, refer to How-To: Setup and Monitor
Modbus Connected Devices (Inverters, Meters & Sensors).
4. Connect the power supply’s DC output leads to the CCA power terminals:
Rail power supply:
External power supply:
Complete all
communications connections before powering on the CCA.
