Grid voltage is too high (redundant monitoring)

What does 0103* mean?

The inverter's redundant 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 shut down and monitor the grid for 30 seconds before attempting to reconnect.

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