Possible Causes

RTC chip failure on PCB, Backup battery/capacitor failure, Corrupted schedule data, Firmware bug in timer logic

How to Fix / Troubleshooting

Safety first: This is a functional fault, not typically a direct safety issue.

  • 1. Disable schedules: In the Zappi menu, turn off all timed boost and schedule functions, then test charging in FAST mode.
  • 2. Correct date/time: Manually set the correct date and time, or allow synchronization via the myenergi hub if connected.
  • 3. Firmware update: Update to the latest firmware to fix any known RTC/scheduling issues.
  • 4. Factory reset schedules: Clear all schedules and recreate them from scratch rather than editing old entries.
  • 5. Observe time drift: If the clock loses time rapidly or resets after short power cuts, the internal RTC backup (battery/capacitor) may have failed.
  • 6. Replace main PCB if RTC is defective: The RTC is integrated on the main PCB and not usually serviceable separately.
