Learn about SMA Sunny Boy Error Code 60, its meaning, causes, and solutions for troubleshooting.
Error Code 60 indicates a self-diagnosis failure in the SMA Sunny Boy inverter. This can lead to operational issues and requires troubleshooting to resolve.
To troubleshoot Error Code 60, check the inverter's connections and settings. Ensure that the firmware is up to date and consult the user manual for specific guidance.
Error 60 indicates a failure in the inverter's self-diagnosis, often linked to insulation resistance (RISO) measurements. When the inverter detects an anomaly in the insulation integrity of the DC circuit, it triggers this fault to prevent potential ground faults, which could pose safety hazards. The inverter continuously monitors for ground faults and ensures that the current remains within safe operational limits, aligning with NEC requirements for grounding and bonding.
Upon encountering Error 60 on the SMA Sunny Boy inverter, users will typically observe an orange fault LED illuminated on the unit. In addition, monitoring applications may display alerts indicating a self-diagnosis failure. The system's energy production may drop significantly, leading to reduced or zero output from the inverter.
Always consult a licensed electrician or certified solar installer when troubleshooting electrical components to ensure safety and compliance with local codes.
To avoid encountering Error 60 in the future, ensure regular maintenance checks of the solar array and inverter. Inspect all wiring for damage, especially after severe weather events. Implement proper cable management to avoid wear and tear, and consider using weatherproof junction boxes. Regularly update the inverter firmware to ensure optimal performance and compliance with the latest standards.
