Possible Causes
Incorrect time zone or clock setting, Conflicting schedules or overrides in app, Firmware bug in scheduler, RTC failure on control board
How to Fix / Troubleshooting
Note: This is a control/logic issue, not an electrical fault.
- Check time settings: In the Enphase app, verify the charger's time zone and current time are correct.
- Review schedules: Ensure there are no overlapping or conflicting schedules and that the schedule is enabled for the correct days.
- Test immediate charge: Disable scheduling and start an immediate charge to confirm hardware is functional.
- Update firmware: Apply any available updates that may address scheduling bugs.
- If still failing: The RTC or scheduler logic on the control board may be faulty; board replacement may be required.
