Learn how to troubleshoot and resolve a Pylontech battery over-temperature alarm effectively.
Overheating can occur due to high ambient temperatures, poor ventilation, or excessive load. Ensure the battery is in a suitable environment.
Regularly monitor battery temperatures and ensure proper airflow around the unit. Consider installing temperature sensors for real-time alerts.
The 'Over-Temperature' alarm is primarily triggered when the internal temperature of the battery exceeds safe operational limits, which can be due to various factors. The inverter monitors the battery's temperature as part of its safety protocols. If the temperature exceeds predefined thresholds, the inverter will cease charging and discharging to prevent damage. This behavior is part of the battery management system (BMS), which relies on accurate temperature readings and can be affected by resistance measurements (RISO) and ground fault detection. If the battery exceeds its rated temperature, it may indicate a malfunction within the BMS or environmental factors leading to inadequate cooling.
When a Pylontech battery triggers an 'Over-Temperature' alarm, users may observe a red LED indicator flashing on the battery unit. Additionally, monitoring applications may display alerts indicating an over-temperature condition, and system performance may drop significantly, with reduced power output from the inverter. The associated inverter may also show fault codes related to temperature issues.
Always consult a licensed electrician or certified solar installer when troubleshooting electrical systems. Improper handling can lead to serious injury or equipment damage.
To avoid future over-temperature alarms, ensure that the system site is well-ventilated and that ambient temperatures remain within the specified range for the battery. Regularly inspect and clean the server rack to prevent dust accumulation. Additionally, routinely check inverter settings and battery performance to ensure they remain within optimal operating conditions.
