Troubleshooting Error 105 (Power Meter Failure) on Eve Single and Double chargers
Issue
When a charging station displays Error 105 (Power Meter Failure), it typically indicates a communication or hardware issue with the kWh meter. It may present itself as a persistent error message on the screen, a non-responsive power meter, or a diagnostic log entry stating: "Failed to acquire parameters, replace kWh meter."
This article describes the steps to identify the root cause and what is necessary to resolve the issue.
