Explore the causes of a Sonnen discharging error during power use and find solutions.
Common causes include battery management system issues, incorrect settings, or hardware malfunctions.
Check the battery settings, ensure proper connections, and consult the user manual for guidance.
The discharging error is typically triggered by the inverter's internal safety protocols. Inverters monitor various parameters including battery state of charge, output voltage, and ground fault conditions. If the inverter detects conditions such as low battery voltage, excessive current draw, or an insulation fault (RISO measurement), it will initiate a shutdown to protect both the battery and the inverter from damage. The system is designed to prioritize safety and operational integrity, hence the discharging error.
Users may observe an error message on the monitoring app indicating a discharging error. LED indicators on the inverter may blink in a specific pattern, often signaling a fault. Additionally, there may be a noticeable drop in power availability, with loads losing power unexpectedly during usage.
Always consult a licensed electrician or certified solar installer when diagnosing or repairing electrical issues to ensure compliance with safety standards and local codes.
To prevent future discharging errors, regularly monitor battery health and state of charge, ensuring it is maintained within the recommended range. Schedule routine inspections of all electrical connections and components, including the inverter and junction boxes, to detect early signs of wear or corrosion. Additionally, keep the inverter firmware updated to leverage the latest operational enhancements and safety protocols.
