What does 0104* mean?

The inverter's standard monitoring system has detected an overvoltage condition on the utility grid. This indicates that the AC voltage has exceeded acceptable limits, potentially causing damage to the inverter or connected equipment. The inverter will switch to the 'Disturbance' operating state.

• Unstable utility grid voltage.
• Improperly functioning external fuses.
• Loose AC cable connections.
