Tigo Cloud Connect Advanced (CCA) 346-00000-00 Standalone Data Logger/Gateway

The Tigo Cloud Connect Advanced (CCA) 346-00000-00 is a compact solar data logger and communications gateway that serves as the monitoring and rapid shutdown hub for Tigo TS4 module-level power electronics (MLPE). Measuring just 1.2 × 4.5 × 2.8 in. (31 × 115.5 × 71.5 mm) and DIN rail mountable, it collects per-module performance data from up to 900 TS4 units and streams it to the Tigo Energy Intelligence cloud platform via Ethernet, Wi-Fi, or optional cellular. Offered as a standalone unit, the 346-00000-00 is intended for installers and integrators who supply their own power source, TAP, and enclosure to match a specific installation requirement.

Key specifications

• Monitoring capacity: up to 900 TS4 units per CCA via up to 7 TAPs
• Input voltage: 12–24 VDC ±2% (2 TAPs or fewer); 24 VDC ±2% required for 3 or more TAPs; 1 A max; 3–10 W
• Connectivity: Ethernet and Wi-Fi built-in; optional cellular (module sold separately)
• Third-party integration: Modbus RS485 — inverters, charge controllers, weather stations, and revenue-grade meters from all major manufacturers
• Physical & certifications: 0.28 lbs. (126 g); -4°F to 185°F (-20°C to 85°C); max altitude 9,840 ft (3,000 m); DIN rail bracket included; CE, UKCA, FCC, UL (CSA), IEC certified

See every module, not just the string

String inverters report aggregate output — when one module drops due to shading, soiling, or a cell defect, the loss is averaged across the string and easy to miss for weeks or months. Paired with a Tigo TAP and TS4 units, the CCA collects individual module performance data and surfaces it in the Tigo Energy Intelligence platform as current and historical trends per panel. That visibility translates directly into faster fault identification, more accurate yield-loss attribution, and cleaner documentation for manufacturer warranty claims — all without adding a separate monitoring subscription.

Key Applications

• Residential rooftop systems — provides granular module-level monitoring for homes using TS4-A-O, TS4-A-S, or TS4-A-M units; a single CCA scales up to 900 modules by adding TAPs.
• Commercial multi-string arrays — the 900-unit capacity and Modbus connectivity allow one CCA to span large installations with full inverter, meter, and weather station integration.
• NEC 690.12 rapid shutdown compliance — when paired with a Tigo TAP, the CCA controls module-level deactivation to meet NEC 2017, 2020, and 2023 Section 690.12 requirements.
• Custom panel and enclosure builds — the standalone format is the right choice when the power supply, housing, and TAP are already specified or sourced separately for a custom switchgear or combiner installation.
• CCA replacements in existing Tigo systems — a direct swap for a failed CCA in any installation where the TAP, enclosure, and power supply are already in place.

Powering and pairing the CCA

The 346-00000-00 requires an external DC power supply — 12–24 VDC is acceptable for systems using two or fewer TAPs, but installations with three or more TAPs must provide a stable 24 VDC ±2% source. The CCA connects to each Tigo Access Point (TAP) via its RS485 GW/TAP port, with the TAP handling wireless mesh communication to TS4 units up to 115 ft (35 m) away. Modbus-equipped third-party devices — inverters, charge controllers, batteries, meters — connect to the RS485-1 or RS485-2 ports. A wired Ethernet or Wi-Fi network connection is required for cloud monitoring through the Tigo Energy Intelligence platform; a cellular module is available as an optional upgrade for sites without reliable broadband. For outdoor installations, an IP68/Type 4R enclosure must be sourced separately — the 348-00000-52 kit bundles the CCA, TAP, DIN rail power supply, and outdoor enclosure for sites where all four components are needed together.

Why choose the Tigo Cloud Connect Advanced (CCA) 346-00000-00?

The 346-00000-00 delivers the complete CCA feature set without bundling hardware that many installation scenarios already account for — making it the practical choice for custom panel builds, CCA-only replacements, and integrators who specify their own power delivery and enclosure. Its Modbus compatibility with inverters, charge controllers, and revenue-grade meters from all major manufacturers means it functions as a universal data hub regardless of the surrounding system architecture. Rapid shutdown compliance through NEC 2017, 2020, and 2023 Section 690.12 ensures the unit remains code-current across multiple code cycles without a hardware swap.
