- 401Error codeGrid fault / Island grid (401) The inverter is no longer in grid parallel operation and has stopped feed-in operation for safety reasons. Corrective measures: Check the grid connection for significant, short-term frequency fluctuations
- 401-404Error codeGrid error
- 405Error codeExt grid disconnect due to undesired island grid Unintended stand-alone grid is present at connection AC2 of the Sunny Island at line conductor Lxx. Corrective measures: Ensure that the insulated wires at connection AC2 are securely connected and that the conductors in the terminals are free of insulation. Corrective measures for a generator: Implement control of the contactor via a Sunny Island multifunction relay. To do so, set the parameter Operating mode of multifunction relay to Automatic generator request. Set the parameter Sensitivity of generator failure detection to a lower sensitivity level. Corrective measures for a utility grid: Contact the Service ( > Contact)
- 501Error codeGrid fault / Grid frequency disturbance (501) The power frequency is not within the permissible range. The inverter has disconnected from the utility grid. Corrective measures: If possible, check the power frequency and observe how often major fluctuations occur. If fluctuations occur frequently and this message is displayed often, contact the grid operator. The grid operator must approve changes to the operating parameters of the inverter. If the grid operator gives his approval, discuss any changes to the operating parameters with the SMA Service Line
- 504Error codeGrid fault The frequency of the generator or the utility grid of the Sunny Island at line conductor Lxx is too low or too high. Corrective measures for a generator: The generator may be overloaded. Reduce the total power of the loads by staggering their use over time.

- 6427Error codeself-diagnosis
- 6438Error codeself-diagnosis

Possible causes: grid voltage is too high; a PV module is defective, soiled or shaded; a cloudy or foggy day. If the grid voltage is outside the permissible range due to local grid conditions, contact the grid operator. The grid operator must approve changes to the operating parameters of the inverter. Therefore, determine the voltage during inverter operation using a communication product.

- 6610Error codeOverload Battery voltage is temporarily too high.
- 6612Error codeOverload Excessive current has been applied to the internal transfer relay of the Sunny Island at line conductor Lxx.
