Learn about Fronius Error Code 1185 related to battery BMS communication loss and solutions.
Error Code 1185 indicates a communication loss between the battery management system and the inverter. This can lead to performance issues.
To troubleshoot Error Code 1185, check the connections between the battery and the inverter. Ensure all cables are secure and undamaged.
The Fronius Gen24 inverter triggers error 1185 when it detects a loss of communication with the BMS. This may occur due to several electrical logic failures, including issues with the data communication lines that connect the inverter to the battery system. If the inverter detects a fault in the insulation resistance (RISO), it may shut down to prevent potential hazards. The BMS is crucial for monitoring battery health and performance; any disruption can lead to operational failures or safety concerns, such as overcharging or deep discharging.
Upon encountering error 1185, users may observe the inverter's LED flashing in a specific pattern, often accompanied by alerts in the monitoring app indicating a communication failure with the battery management system (BMS). Additionally, there may be a noticeable drop in energy production and battery charge levels, leading to reduced system efficiency.
Always consult a licensed electrician or certified solar installer for troubleshooting and repairs to ensure safety and compliance with local electrical codes.
To avoid future occurrences of error 1185, ensure regular maintenance checks on the battery system, including visual inspections of wiring and connectors. Keep software and firmware updated to the latest versions provided by the manufacturer. Additionally, monitor environmental conditions that may affect battery performance and maintain optimal operating temperatures.
