Learn how to troubleshoot and fix the Pylontech ALM battery LED blinking twice due to overcurrent issues.
A blinking LED on the Pylontech ALM typically indicates an error condition, such as overcurrent. This requires immediate attention to prevent damage.
To prevent overcurrent issues, ensure proper load management and check for any short circuits in the wiring. Regular maintenance can also help.
The overcurrent fault is triggered by the battery management system (BMS) detecting a current draw that exceeds the battery's rated capacity. This condition can occur due to excessive load demand, which forces the inverter to draw more current than the battery can safely supply. The BMS continuously monitors parameters such as voltage, current, and temperature to protect the battery from damage, and any significant deviation from normal operating conditions will result in fault activation.
Upon encountering an overcurrent fault, the Pylontech ALM battery will exhibit a blinking red LED twice, indicating a fault condition. Users may also notice a drop in system performance through monitoring apps, with alerts indicating that the battery is not functioning optimally. Additionally, connected loads may experience intermittent power supply issues.
Always consult a licensed electrician or certified solar installer when performing troubleshooting or repairs to ensure compliance with safety standards and regulations.
To avoid future overcurrent issues, ensure that the total load connected to the inverter is within the battery's rated output. Regularly inspect all wiring for integrity and ensure that the BMS settings are correctly configured for the specific battery model. Additionally, maintain optimal operating temperatures to enhance battery performance and longevity.
