Tigo TS4-A Manual

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.

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.

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.
   

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)

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.
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 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-partysupply with 120/240V AC input and 24VDCoutput.

A CCA also includes two three-pin RS-485 connections to enable up to 32 Modbus communications with Yd-party data sources such as inverters, charge controllers, revenuegrade 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:
   

3. If used, connect any 3rd-partydevices using Modbus to the RS-4851 and RS-4852 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 120 resistor must connect the + and — terminals on the last Modbus device.

4. Connect the power supply's DC output leads to the CCA power terminals:
   

Complete all communications connections before powering on the CCA.

LED Status Indicators
The LED on the right of the CCA indicates system status as well as the status of the commissioning Discovery process:

Use the Tigo Energy Intelligence (EI) app (available in the App Store or Google Play) to troubleshoot CCA issues.

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.

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.
