Ah Exceeded

Fronius · Perfect Charging

Was bedeutet 34 ?

The total Ampere-hours (Ah) delivered to the battery during charging has exceeded a predefined limit. This is typically a safety mechanism intended to prevent overcharging based on the expected or configured battery capacity, indicating a mismatch or a faulty measurement.

Häufige Ursachen

  • The actual capacity of the connected battery is significantly lower than expected or configured in the charger's settings.
  • An incorrect Ah limit parameter has been set in the charger, allowing it to deliver more charge than safe for the battery.
  • A malfunction in the charger's current integration or Ah measurement circuit, leading to inaccurate accumulation of delivered charge.
