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

• Serial communication via RS232 and RS485
• Network interface via RJ45 (ModBus / LAN)
• Configuration of address and parameters via DIP switches
• Transmission of operational data:
  • Energy production
  • Device status
  • Alarms and faults
• Connection to:
  • Diagnostic PCs
