Learn about Deye inverter error code F35, its meaning, causes, and solutions for grid connection issues.
Error code F35 indicates that the inverter is unable to connect to the grid. This can occur due to various reasons such as grid outages or configuration issues.
To troubleshoot, check the grid voltage and ensure the inverter settings are correct. Additionally, inspect the wiring and connections for any faults.
The F35 fault code is triggered when the inverter detects that it is not connected to the utility grid. This is often a result of the inverter's internal safety protocols, which monitor grid parameters such as voltage and frequency. If these parameters fall outside acceptable limits, or if the inverter cannot establish communication with the grid, it will enter a fault state to protect both itself and the solar array. This may involve checks for ground faults, incorrect voltage levels, or communication failures that would prevent safe operation.
When your Deye inverter displays the F35 error code, it indicates a lack of grid connection. Users may observe LED indicators flashing in a specific pattern, typically alternating or solid red, and may receive alerts via the monitoring app indicating no production or grid connection. This disruption can lead to a noticeable drop in energy production, as the inverter is unable to feed power into the utility grid.
Always consult a licensed electrician or certified solar installer when diagnosing or repairing electrical issues to ensure safety and compliance with local codes.
To prevent future occurrences of the F35 error, regularly maintain your solar power system by inspecting wiring connections, ensuring proper inverter settings, and performing routine insulation resistance tests. Additionally, consider installing surge protection devices to safeguard against voltage spikes.
