applicable electrical codes and instructions in the
TS4-A with CCA and TAP Installation Manual.
• Improper installation may cause damage not covered
by the warranty.
• Adhere to ANSI/NFPA 70 (North America) and local
electrical code requirements.
1. Save the QR/barcode sticker on a site map or
string list.
2. Attach the TS4 to the top of the PV module frame.
If frame thickness is ≤35mm (1.4in), install with the
TS4 label facing the PV module.
3. Connect the short input cables to the PV module.
4. Connect the long output leads to the adjacent TS4.
Install TS4s
• Always assume that TS4s are in an ON state.
• Ensure cable glands face down and cannot collect moisture.
• Disconnect TS4s from the array string before disconnecting
from a PV module.
• Always connect short input cables before connecting
long output cables. Failure to do so may void warranty.
System Layout
• The Cloud Connect Advanced (CCA) data logger/gateway connects to the cloud via Ethernet
or WiFi and to other devices via Modbus.
• The CCA has a wired connection to the Tigo Access Point (TAP).
• The TAP communicates wirelessly with TS4-A-O/S/M MLPE via a mesh network.
CCA
TAP 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.
• When used as a PVRSS solution, all solar modules in the array must be
equipped with TS4-A-O/S and TAP PVRSE with a permanent or temporary (for
commissioning) CCA. Rapid shutdown is initiated upon AC power loss that stops
power to the TAP.

Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The Tigo TS4-A-O/S/M with TAP and CCA is a comprehensive solution designed to optimize and manage solar PV systems, providing module-level power electronics (MLPE) for enhanced performance, safety, and monitoring. This system is particularly focused on ensuring compliance with rapid shutdown requirements, a critical safety feature for PV installations.

Function Description

The core function of the Tigo system is to provide module-level optimization, monitoring, and rapid shutdown capabilities for solar PV arrays. It consists of three primary components:

• TS4-A-O/S/M MLPEs: These are attached to individual PV modules and perform various functions depending on the model. The 'O' (Optimization) model provides module-level power optimization, maximizing energy harvest from each panel, especially in conditions of shading or module mismatch. The 'S' (Safety) model offers module-level monitoring and rapid shutdown. The 'M' (Monitoring) model provides module-level monitoring. All models are designed to enable rapid shutdown, ensuring the array can be quickly de-energized for safety during emergencies or maintenance.
• Tigo Access Point (TAP): The TAP acts as a wireless communication hub for the TS4 MLPEs. It collects data from the TS4s and relays commands to them, including rapid shutdown signals. It communicates with the Cloud Connect Advanced (CCA) via a wired connection.
• Cloud Connect Advanced (CCA): The CCA is the central data logger and gateway for the entire system. It connects to the TAP, collects all system data, and uploads it to the Tigo Energy Intelligence (EI) cloud platform via Ethernet or WiFi. It also serves as the control point for initiating rapid shutdown and provides system status indicators.

Together, these components create a robust ecosystem that allows for granular control and visibility into the PV system's performance. The system ensures that in the event of an AC power loss (e.g., inverter shutdown or utility grid disconnection), the TS4s rapidly de-energize the PV modules, bringing the array to a safe voltage level as required by electrical codes.

Usage Features

The Tigo system is designed for ease of installation and operation, offering several features that enhance its usability:

• Flexible Installation: TS4s can be easily attached to the top of PV module frames using removable spring clips or M8 bolts for frameless modules. The system supports various frame thicknesses, with specific instructions for mounting based on the thickness to ensure proper fit and label visibility.
• Modular Design: The system's modular nature allows for scalable deployment, accommodating arrays of different sizes. One TAP can communicate with up to 300 TS4s, and one CCA can manage up to 7 TAPs and 900 TS4s, providing flexibility for residential, commercial, and utility-scale installations.
• Centralized Monitoring and Control: The CCA, in conjunction with the Tigo EI mobile app and cloud platform, provides comprehensive monitoring of the PV system's performance at the module level. Users can track energy production, identify potential issues, and remotely manage the system, including initiating rapid shutdown.
• Rapid Shutdown Compliance: The system is certified as a UL 1741 photovoltaic rapid shutdown system (PVRSS), meeting stringent safety requirements. Rapid shutdown is automatically initiated upon AC power loss, ensuring safety for first responders and maintenance personnel.
• Intuitive Status Indicators: The CCA features an LED status indicator that provides clear visual feedback on the system's operational state, including system OK, EI app activity, PV-Off mode, discovery status, warnings, and errors. This helps installers and users quickly diagnose system conditions.
• Mobile App for Commissioning and Testing: The Tigo Energy Intelligence (EI) mobile app is an essential tool for testing and commissioning all system components. It simplifies the setup process and allows for verification of proper functionality.
• Cable Management: The system emphasizes proper cable management, with instructions to ensure cable glands face down to prevent moisture collection, contributing to the longevity and reliability of the components.
• Wiring Flexibility: The TAP and CCA can be connected using 4-wire or CAT5/6 cables, with recommendations for shielded twisted pairs for optimal performance, especially when running near PV conductors.

Maintenance Features

Maintaining the Tigo system is straightforward, with features designed to ensure long-term reliability and ease of service:

• Durable Construction: Components like the TAP are designed with NEMA 4 enclosures, ensuring protection against environmental elements such as dust and water, which is crucial for outdoor installations.
• Clear Installation Guidelines: The quick start guide provides detailed instructions and warnings to prevent improper installation, which could lead to damage not covered by warranty. This includes advice against installing physically damaged TS4s, connecting/disconnecting TS4s under load, and ensuring proper cable connections.
• Troubleshooting Support: The CCA's LED status indicators provide immediate feedback on potential issues, aiding in quick troubleshooting. For more complex problems, the Tigo Energy Help Center and support resources are readily available.
• Component Replacement: In the event of a component failure, individual TS4s can be replaced, minimizing downtime and cost compared to systems requiring replacement of larger, more integrated components.
• Firmware Updates: As a connected system, the Tigo platform allows for potential over-the-air firmware updates to the CCA and other components, ensuring the system remains up-to-date with the latest features and security enhancements.
• Preventative Measures: The emphasis on proper cable gland orientation and avoiding physical damage during installation serves as a preventative maintenance measure, reducing the likelihood of future issues.
• Warranty Considerations: Adhering to the installation instructions and maintaining the system in accordance with applicable electrical codes helps ensure that the warranty remains valid, protecting the investment.
• Accessible Resources: Tigo provides a comprehensive suite of resources, including a Help Center, Downloads page, and various videos and articles, to assist users with installation, operation, and maintenance.
