F36
AI L1L2 Under Voltage
Schneider Electric · XW Pro NA Operation Guide
What does F36 mean?
This fault indicates an L1-L2 under-voltage condition (108 V equivalent based on F34 reference) detected by the anti-islanding protection, triggering a slow disconnect. This mechanism ensures the inverter disconnects from an unstable grid, protecting both the inverter and grid from potential damage due to insufficient voltage.
