Set Charging Time Cannot Be Reached

Fronius · Perfect Charging

What does 38 mean?

The charging process is unable to complete within the configured total charging time. This suggests that the battery is taking longer than expected to charge, potentially due to its condition, the charger's limitations, or an incorrect time setting.

Common Causes

  • The battery's actual capacity is higher than configured, or its internal resistance has increased due to degradation, requiring more time to charge.
  • The charger's output current is lower than expected or limited due to internal conditions or load.
  • The charger is operating at reduced power, extending the required charging duration.
  • An incorrect total charging time parameter has been set, which is too short for the battery and charger capabilities.

Repair Steps & Checklist

  1. 1

  2. 2

    Check the charger's current output during the charging process to ensure it is delivering the expected current.

  3. 3

    Review and adjust the configured total charging time parameter in the charger's settings to match the actual battery capacity and charger capabilities.
