Tigo TS4-A-O units are more than just power optimisers.
When combined with the Energy Intelligence platform and the Tigo CCA Kit (Cloud Connect Advanced and Accessories Kit), they provide the foundation for effective control and long-term monitoring of photovoltaic systems.
Tigo TS4: a Universal PV Control System
Thanks to their universal compatibility, Tigo optimisers allow system data to be collected within a single platform – Energy Intelligence – even when third-party inverters are used.
For installers, this means having all relevant system information available in one place, without having to switch between different interfaces to monitor a single PV installation.
Tigo TS4 and CCA Kit
With a TS4-A-O installed on each module and a CCA Kit, the PV system can be monitored at module level. This applies to both new installations and retrofit projects, regardless of the inverter brand.
In practice, each module becomes a window into the actual performance of the PV system. Energy Intelligence collects module-level data and turns it into actionable information, including:
- actual energy production
- system performance
- anomalies
- string imbalances
- underperforming modules or areas affected by shading.
This means that problems are no longer assumed – they can be identified directly from the data.
Fleet Manager
With the latest update to the EI platform, Fleet Manager further streamlines PV fleet management.
Installers can view all systems equipped with TS4-A-O units from a single dashboard, with the ability to filter installations according to parameters such as system health, location, inverter type and active alarms.
Greater Transparency and Faster Diagnostics
The real value of TS4-A-O units becomes clear through module-level data. With continuous performance updates, Energy Intelligence can quickly identify whether a module is producing less than the others, whether a string is unbalanced or whether an optimiser is reporting an anomaly.
For the system owner, this means greater transparency. For the installer, it means faster diagnostics and less time spent searching for faults on the roof.
One of the most valuable features of the Energy Intelligence platform is the Reclaimed Energy metric. Thanks to TS4 units, the system can quantify how much energy is recovered through module-level optimisation – in other words, energy that would otherwise be lost due to shading or mismatch.
This makes the actual impact of power optimisers clearly measurable: not only in terms of total energy production, but also as quantifiable added value. For installers, it provides a powerful tool to demonstrate the ROI of the solution; for PV system owners, it offers tangible evidence of the benefits delivered over time.
