Battery Over Temperature
Schneider Electric · XW Pro NA Operation Guide
Hva betyr F44 ?
This Automatic Fault indicates a battery over-temperature shutdown at 60 °C to prevent damage to the battery bank. The XW Pro will recover and enable operation again when the temperature falls to 50 °C.
Vanlige årsaker
- Inadequate ventilation or cooling in the battery enclosure, leading to heat buildup (e.g., ambient temperature > 40°C).
- Excessive charging or discharging current exceeding battery manufacturer specifications, generating internal heat.
- Faulty battery temperature sensor providing inaccurate readings (e.g., reporting higher temperature than actual).
- High ambient temperature in the equipment room, especially during peak load or charging cycles.
- Internal battery cell degradation or short circuit, causing localized overheating.

- 1
Measure the actual battery temperature using an infrared thermometer or thermocouple directly on battery terminals and cell surfaces.
- 2
Verify ambient temperature in the battery enclosure and ensure proper airflow, fan operation, and clear ventilation paths are maintained.
- 3
Check battery charging/discharging current (e.g., parameter P5-01 for charge current limit) against battery manufacturer specifications.
- 4
Inspect the battery temperature sensor (e.g., located on battery terminal or cable) for physical damage, corrosion, or loose connections.
- 5
Reduce the charging current limit via inverter parameters (e.g., Parameter P5-01) to decrease heat generation during charging cycles.
