How to Fix / Troubleshooting

Safety: Turn off power at the breaker before handling CTs or opening the charger.

  • Check CT configuration: If using external Emporia CTs for energy monitoring, verify they are installed on the correct conductors and oriented properly.
  • Inspect sensor connections: With power off, open the charger and ensure the internal current sensor connectors are firmly seated on the control board.
  • Recalibrate via app: Use any available calibration or reset functions in the Emporia app to reinitialize energy measurement.
  • Update firmware: Install the latest firmware to correct any known metering issues.
  • If readings remain inaccurate: The internal current sensor or metering IC on the control board may be defective. Replace the control board assembly.
