Unique ID conflict
Fronius · Primo GEN24 Operating Instructions
What does 419 mean?
This code indicates a conflict with the inverter's unique ID. This typically occurs in multi-inverter installations or after component replacement, where the system detects duplicate or invalid unique identifiers, potentially disrupting communication or operation.
Common Causes
- Duplicate unique ID assigned to multiple inverters in a network.
- Corrupted unique ID stored in the inverter's memory.
- Incompatibility after a PC board replacement if the ID is stored on the replaced component.
