Tigo Cloud Connect Advanced and TAP Gateway Setup Guide

Key Takeaways

• The Tigo Cloud Connect Advanced (CCA) is the central data hub and rapid shutdown safety controller for TS4 optimizer arrays.
• The Tigo Access Point (TAP) is a rooftop antenna that provides wireless mesh communication to up to 300 TS4 units.
• Connect the CCA to the TAP using a 4-conductor shielded RS485 communication cable, supplying both DC power and data.
• Always ensure complete AC circuit isolation and lock-out before installing CT clamps on live busbars.

What are the Tigo Cloud Connect Advanced (CCA) and Tigo Access Point (TAP)?

The Tigo Cloud Connect Advanced (CCA) and Tigo Access Point (TAP) form the core communication and safety components for a Tigo-optimised solar array. The Tigo CCA serves as the central data hub and rapid shutdown safety controller for TS4 optimizer arrays. It collects performance data and manages safety functions.

The Tigo Access Point (TAP) is mounted on the solar array frame. Its primary role is providing wireless mesh communication to up to 300 TS4 units, acting as the bridge between the optimisers on the roof and the CCA gateway.

How the Tigo Gateway System Works

The Tigo gateway system facilitates communication and safety across your solar installation. The CCA and TAP work together to monitor your system and ensure rapid shutdown capability.

The CCA connects to the TAP using a 4-conductor shielded RS485 communication cable. This cable supplies both DC power and data between the two units. From the TAP, a 2.4GHz wireless mesh network is established, allowing it to communicate with individual TS4 optimisers on the solar panels. This wireless link enables the TAP to receive performance data from the TS4 units and send commands, including rapid shutdown signals.

A critical safety feature is the rapid shutdown mechanism. Disconnecting AC power to the CCA triggers automated TS4 rapid shutdown, de-energizing DC string voltages at the module level. This ensures safety for emergency responders and maintenance personnel by quickly reducing high DC voltages on the rooftop. The system is compatible with standard single-phase and three-phase electrical distribution systems globally and is engineered for universal residential and commercial off-grid and grid-parallel energy storage systems worldwide.

Wiring the Tigo CCA to the TAP Gateway

Proper wiring between the CCA and TAP is essential for reliable communication and system operation. The connection uses RS485 differential communication.

When connecting the CCA to the TAP, use a 4-conductor shielded RS485 communication cable. This cable is responsible for both supplying DC power to the TAP and transmitting data between the two devices. It is important to maintain shielded twisted-pair cabling to ensure robust communication. Verify proper RS485 communication baud rate settings during setup to prevent communication errors.

The Tigo Access Point (TAP) should be mounted on the solar array frame. From this position, one Tigo TAP provides wireless coverage over a 35-metre line-of-sight radius across contiguous solar rooftop planes, allowing it to communicate effectively with up to 300 TS4 units.

Ensuring Safe Installation and Operation

Safety is paramount during the installation and maintenance of any solar energy system. While some basic checks can be performed by a homeowner, specific tasks require the expertise of an accredited installer.

What you can check yourself:

• Visually inspect all external cabling for any signs of damage or wear.
• Understand how to disconnect AC power to the CCA, which activates the rapid shutdown function.

What requires an accredited installer:

• AC Circuit Isolation: Ensure complete AC circuit isolation and lock-out before installing CT clamps on live busbars. This prevents electrical shock.
• Earthing: Bond inverter chassis ground and battery metal enclosure to the main installation earthing terminal. This is crucial for protective bonding and safety.
• Internal Wiring: Any work involving opening the unit, changing internal wiring, or adjusting grid-protection settings must be performed by a certified installer. Changing these settings yourself can breach your connection agreement and compromise safety.

Always follow the manufacturer's instructions and local electrical regulations.

Tigo System Compliance and Compatibility

The Tigo system is designed to meet stringent safety and operational standards, ensuring broad applicability across various installations. It complies with international microgeneration safety and grid protection standards, providing assurance of its reliability and safety performance.

The system offers global electrical network support, being compatible with standard single-phase and three-phase electrical distribution systems worldwide. Its universal residential and commercial scope means it is engineered for both residential and commercial off-grid and grid-parallel energy storage systems across the globe. This broad compatibility makes Tigo solutions versatile for diverse solar energy projects.
