The Riello FW15-AI-01 is a communication and control board designed for Riello UPS systems and photovoltaic inverters, enabling integration into industrial monitoring and supervision networks.
This module acts as a data interface gateway, allowing communication between the inverter (or UPS) and external systems via serial protocols and network interfaces.
It is typically installed in the expansion slot of the inverter/UPS to provide advanced communication capabilities.
⚙️ Main Functions
