1. Penyediaan: Ensure all PV modules are de-energized. Verify that the inverter is compatible with Tigo TS4-A-F and has an integrated or external RSS transmitter for PLC communication.
2. Pemasangan: Attach one TS4-A-F unit to the frame of each PV module. The unit is designed to snap securely onto the module frame. Ensure proper ventilation and avoid direct exposure to extreme weather conditions if possible.
3. PV Module Connection: Connect the positive and negative output cables from the PV module to the corresponding input connectors of the TS4-A-F unit. Use the MC4 connectors provided.
4. String Connection: Connect the output cables of the TS4-A-F unit to the next TS4-A-F unit in the string, or directly to the inverter's input if it's the last unit in the string. Maintain correct polarity (positive to positive, negative to negative).
5. Inverter Connection: Connect the PV string to the compatible inverter. Ensure the inverter's rapid shutdown transmitter is active and properly configured to communicate with the TS4-A-F units via PLC.
6. Pengaktifan Sistem: Once all connections are secure and verified, energize the PV array and inverter according to the manufacturer's instructions. The TS4-A-F units will communicate with the inverter to enable power production.

For detailed wiring diagrams and specific installation requirements, refer to the official Tigo installation guide available on the manufacturer's webtapak.

5. Operasi

The Tigo TS4-A-F operates automatically in conjunction with a compatible inverter and its rapid shutdown transmitter. When the inverter is operating normally, it sends a keep-alive signal via Power Line Communication (PLC) to the TS4-A-F units. This signal allows the TS4-A-F to enable power output from the PV modules.

In the event of a rapid shutdown command (e.g., initiated by a safety switch, utility grid outage, or fire alarm), the inverter's transmitter ceases to send the keep-alive signal. Upon loss of this signal, each TS4-A-F unit automatically de-energizes its connected PV module within seconds, reducing the voltage in the PV array to a safe level as required by NEC standards. This ensures the safety of emergency responders.

To resume normal operation, the rapid shutdown condition must be cleared, and the inverter must re-establish communication with the TS4-A-F units by sending the keep-alive signal.

6. Penyelenggaraan

The Tigo TS4-A-F is designed for minimal maintenance. Regular inspections of the PV system are recommended to ensure optimal performance and safety.

• Pemeriksaan Visual: Periodically inspect the TS4-A-F units and their connections for any signs of physical damage, corrosion, or loose connections.
• Pembersihan: Jika perlu, bersihkan bahagian luar unit dengan lembutamp kain. Jangan gunakan pembersih atau pelarut yang melelas.
• Pemantauan Prestasi: Monitor the performance of your PV system through your inverter's monitoring interface. Any significant drop in module-level power output could indicate an issue with a TS4-A-F unit or the connected module.
• Pemeriksaan Profesional: It is advisable to have a qualified solar technician perform a comprehensive system check periodically, especially after severe weather events.

Do not attempt to open or service the TS4-A-F unit yourself. Contact qualified service personnel for any repairs or advanced troubleshooting.

7. Penyelesaian masalah

If you experience issues with your Tigo TS4-A-F system, consider the following troubleshooting steps:

• No Power Output from a Module:
  • Check all MC4 connections for secure and correct polarity.
  • Verify that the inverter is operating and sending the PLC keep-alive signal.
  • Inspect the PV module itself for any damage.
• System Not Shutting Down Rapidly:
  • Ensure the inverter's rapid shutdown transmitter is functioning correctly.
  • Confirm that the rapid shutdown initiation method (e.g., external switch) is properly connected and activated.
  • Verify compatibility between the inverter and TS4-A-F units.
• Operasi sekejap:
  • Check for loose wiring or damaged cables.
  • Ensure there are no sources of electromagnetic interference affecting PLC communication.

For persistent issues, consult the inverter's user manual or contact Tigo support or a certified solar professional.
