Learn about Fronius Error Code 567, its causes, and how to resolve grid voltage issues.
Error Code 567 indicates that the grid voltage is too high for the inverter to operate safely. This can lead to shutdowns to protect the system.
You can check grid voltage levels using a multimeter or by accessing the inverter's monitoring system. Ensure the readings are within the specified range.
The Fronius Symo inverter monitors grid voltage as part of its operational safety protocols. When the grid voltage exceeds a predefined threshold, the inverter triggers fault 567, indicating that the grid voltage is too high. This fault is part of the inverter's protective logic to prevent damage to its internal components. The inverter continuously measures the AC voltage and compares it against the nominal values defined by the National Electrical Code (NEC) and manufacturer specifications. If the voltage exceeds these limits, the inverter will shut down to avoid potential damage or safety hazards.
Homeowners may notice the inverter's LED indicator flashing a fault 567, accompanied by alerts on the monitoring app indicating a grid voltage issue. This may also result in a significant drop in energy production, as the inverter disconnects to protect itself from high voltage conditions.
Always consult a licensed electrician or certified solar installer when troubleshooting or performing maintenance on solar equipment to ensure safety and compliance with local electrical codes.
To avoid encountering fault 567 in the future, ensure that the inverter's firmware is kept up to date, conduct regular maintenance checks on all electrical connections, and collaborate with local utility providers to monitor grid conditions. Additionally, consider installing surge protection devices to mitigate the impact of voltage spikes.
