Learn about the Victron Energy B104 unsupported data error, its causes, and solutions.
The B104 error indicates that the data being received is not supported by the system. This can occur due to incompatible firmware or incorrect settings.
To troubleshoot the B104 error, check for firmware updates and ensure all settings are correctly configured. Restarting the device may also help resolve the issue.
The unsupported data error typically arises when the inverter detects discrepancies in the data being received from the B104 battery. This can be triggered by several electrical logic failures, such as a failure in the insulation resistance measurement (RISO), which checks for unintended paths of current that could lead to ground faults. If the inverter's ground fault detection mechanism identifies an anomaly, it may trigger this fault code to prevent potential damage or safety hazards. Moreover, if the battery voltage exceeds or falls below the acceptable grid frequency limits, the inverter may also reject the data as unsupported, leading to operational interruptions.
When encountering the Victron Energy B104 unsupported data error, users may observe the following symptoms: the inverter display may show a blinking fault indicator, and the monitoring app may present alerts indicating data communication issues. Additionally, the system may experience irregular production drops, leading to decreased energy output from the solar array.
Always consult a licensed electrician or certified solar installer when diagnosing or repairing electrical issues to ensure compliance with safety standards and regulations.
To prevent future occurrences of the unsupported data error, regularly inspect and maintain all wiring and connections, ensuring they are secure and free from damage. Additionally, keep the inverter firmware updated and verify that the battery type settings are accurate during system or after any system modifications.
