Inverter AC voltage exceeds limit

What happens if AC voltage exceeds the inverter's limit?

When the AC voltage exceeds the inverter's limit it causes a shut down. Once production stops the inverter will see the grid voltage decrease, so it will attempt to restart. This will continue to happen in a cycle throughout the day. It can be seen on monitoring platforms as multiple faults every day.

What if my inverter is low grid voltage?

If however it really is low grid voltage, then that's a supply issue for Energex to attend to. Also ask what Australian Standards apply to it, for instance AS4755 (for 240V AC systems) disconnects inverter at a higher voltage than one on modern new grid standards for 230V AC.

Why do inverters need to be stopped if grid voltage changes?

This is because the grid voltage is not constant and it will change with the changing of the load and current. At the same time, the output voltage of the inverter will be affected by the grid voltage. When the grid encounters abnormal situation, the inverter power supply shall be stopped to avoid more serious damage on the grid.

When should a solar inverter be stopped?

The solar inverter operation shall be stopped when it exceeds this range. The rated voltage of the single-phase grid is 230V. when the grid voltage is lower than 195.5V or is higher than 253V, principally the inverter shall be stopped. The rated voltage of the three-phase grid is 400V.
