Easee charger stops charging and logs an overvoltage condition; LED may turn red or yellow depending on firmware.

Danger: Overvoltage can damage the charger and vehicle. Do not continue operation until the cause is identified.

• 1. Measure supply voltage: With a multimeter, measure L–N and L–PE at the charger backplate. Confirm that voltages are within the specified range (typically around 230 V L–N).
• 2. Check neutral connection: Ensure the neutral conductor is present, correctly connected, and not loose or broken between the main panel and the charger.
• 3. Verify supply type: Confirm that the charger is configured for the actual supply type (single-phase vs three-phase) in the installer settings.
• 4. Monitor utility voltage: If the mains voltage is consistently high, contact your utility provider. Do not attempt to modify the supply yourself.
• 5. Replace sensing circuit: If measured voltages are normal but the charger still reports overvoltage, the internal voltage sensing circuit may be defective and the main board should be replaced.
