This is an original RS485 monitoring communication board for ABB Aurora / Power-One inverters rated at 10.0kW, 12.0kW, and 12.5kW. The board, labeled 3G83-14/0, enables RS485-based data transmission between the inverter and external monitoring systems such as Aurora Vision, Solar-Log, third-party SCADA, or data loggers.

This module is critical for real-time monitoring, remote diagnostics, and inverter fleet management. If your inverter is not appearing in the monitoring system, this board is often the first component to inspect and replace.

🔄 Condition: Used, professionally tested and fully functional.
