Battery Too Hot (External Sensor)

Fronius · Perfect Charging

¿Qué significa 24 ?

The external temperature sensor indicates that the battery temperature is excessively high. This is a critical safety condition that requires immediate attention to prevent thermal runaway, battery degradation, or potential hazards such as fire.

Causas comunes

  • High ambient temperature around the battery, leading to increased overall temperature.
  • Excessive charging current applied to the battery, generating internal heat faster than it can dissipate.
  • Malfunction of the battery's internal cooling system (if equipped) or an issue with the external temperature sensor mounting.
