ID01The power grid voltage is too high

Name in the manufacturer's documentation (fault list): The power grid voltage is too high[1]

In plain words (editorial)

The grid voltage is too high for the inverter. If it happens only occasionally, the grid was briefly abnormal and the inverter returns to normal automatically when the grid is back to normal.

When to call a service technician: If it happens frequently, contact your installer – protection settings may only be changed by technical support after the grid operator's approval.
