Error Code 567 indicates that the grid voltage exceeds acceptable levels for AU standards. This can lead to inverter shutdowns to protect the system.
To resolve high grid voltage issues, check the local grid voltage levels and consult with your utility provider. Adjustments may be needed to ensure compliance.
The Fronius inverter triggers fault 567 when it detects that the grid voltage exceeds its maximum allowable input voltage, which is designed to protect the inverter from damage. This fault is a safety feature that prevents the inverter from operating under conditions that could lead to overheating or component failure. The inverter continuously monitors the grid voltage through its voltage sensing circuitry. If the grid voltage rises beyond the specified threshold during operation, the inverter will enter a protective state, ceasing operation until the voltage returns to acceptable levels.
When the Fronius inverter displays fault 567, users may observe a red LED indicator blinking in a specific pattern, typically accompanied by alerts in the monitoring app indicating a fault. Additionally, there may be a noticeable drop in energy production, with the system failing to operate or generating significantly less power than expected.
Always consult a licensed electrician or certified solar installer when dealing with electrical faults or system diagnostics to ensure safety and compliance with local codes.
To prevent future occurrences of fault 567, regularly monitor grid voltage levels and ensure that the inverter settings are appropriately configured for local conditions. Conduct routine inspections of the array and junction box for signs of wear or damage. Installing surge protection devices can also help protect the inverter from voltage spikes caused by external factors.
