Tigo EI Link TSS-3PS is a three-phase integration module designed for Tigo energy storage systems. It serves as the central connection and communication point between the hybrid inverter, energy storage system, PV installation and monitoring system.

The device is equipped with Cloud Connect Advanced (CCA), which is responsible for communication, data collection and integration of the system with the Tigo Energy Intelligence platform. This enables monitoring of the installation and, when combined with Tigo TS4 solutions, also module-level monitoring of individual PV modules.

The TSS-3PS model also features an ATS (Automatic Transfer Switch). This component enables the installation to automatically switch to backup power from the energy storage system in the event of a grid outage and return to normal operation once grid power is restored.

EI Link simplifies the construction of a complete Tigo energy storage system by centralizing the key electrical and communication connections. It works with three-phase Tigo EI Inverter hybrid inverters such as the TSI-6K3D, TSI-10K3D and TSI-15K3D, as well as with a compatible Tigo energy storage system.

What role does EI Link play in the Tigo system?

Tigo EI Link TSS-3PS combines the functions of a central connection point, communication module and automatic transfer switch. CCA provides communication and system monitoring, while the ATS is responsible for automatically switching the installation to backup power in the event of a grid failure.

A basic three-phase Tigo energy storage system consists of:

• Tigo EI Inverter hybrid inverter – TSI-6K3D, TSI-10K3D or TSI-15K3D,
• Tigo EI Link TSS-3PS – central connection module equipped with CCA and ATS,
• Tigo GO Battery – high-voltage energy storage system.

The system can also be expanded with Tigo TS4 solutions, providing monitoring and additional functions at the level of individual photovoltaic modules.
