- Grid voltage error
- Check the grid voltage
- Check connections
- Ensure the grid is stable
- Make sure all AC connections are tight.
- 0103 - Grid voltage is too high. Over voltage detected by redundant monitoring.
- 0104 - Grid voltage is too high. Over voltage detected by standard monitoring.
- 0203 - Grid voltage is too low. Under voltage detected by redundant monitoring.
- 0204 - Grid voltage is too low. Under voltage detected by standard monitoring.
- 0205 - Not permitted grid frequency change or grid synchronization not possible
- 0404 - Frequency change per second too high for grid operation
- 0502 - Power frequency is too low. Power frequency disturbance detected by standard monitoring.
- 0503 - Power frequency is too high. Power frequency disturbance detected by standard monitoring.
- 0504 - Power frequency is too low. Power frequency disturbance detected by redundant monitoring.
- 0505 - Power frequency is too high.Power frequency disturbance detected by redundant monitoring.
- 0506 - The inverter has detected a stand alone grid and has disconnected from the utility grid.
- 0801 - One line conductor of the utility grid has failed.
- 0802 - One line conductor of the utility grid has failed.
- 1301 - Left-hand rotating magnetic field isconnected.
- 1500 - The conditions for grid reconnection have not yet been reached aftera grid error.
