Possible Causes

Incorrect maximum current setting on Lucid control board, Mismatched configuration between app and internal DIP switches, Corrupted configuration memory

How to Fix / Troubleshooting

Safety first: Turn OFF power before accessing internal settings.

Steps:

  • Verify current setting: Open the Lucid charger and locate the current-setting DIP switches or rotary selector on the control board. Confirm they match the branch circuit rating and installation manual.
  • Check app settings: In the Lucid charger app, ensure the maximum current does not exceed the hardware setting or breaker rating.
  • Reset to defaults: If available, perform a factory reset from the front panel or app, then reconfigure step-by-step.

Resolution: After correcting settings, power-cycle the charger. If E11 persists, the configuration memory or microcontroller on the control board may be faulty and require board replacement.
