Possible Causes

Failed real-time clock (RTC) chip on control board, Depleted RTC backup battery, Loss of NTP time sync due to network issues, Corrupted time settings in configuration

How to Fix / Troubleshooting

Safety first: Time settings can be adjusted via user interface; opening the unit for RTC battery replacement should be done with power isolated.

  • Check time settings: Using the local display or app, verify that date, time, and time zone are correct. Correct them if necessary.
  • NTP sync: Ensure the charger has internet access and NTP synchronization enabled if supported. Confirm DNS and gateway settings.
  • Disable schedules: Temporarily disable scheduled charging or load management to allow immediate charging while troubleshooting.
  • RTC battery (advanced): If the time resets after every power cycle, the RTC backup battery on the control board may be depleted and require replacement by a technician.

If E019 persists after correcting time and network settings, the RTC hardware on the control board may be defective.
