Alarm 2032Grid Failed

Name in the manufacturer's documentation (fault list): Grid Failed[1]

In plain words (editorial)

The inverter sees no grid: either there is a power outage or the AC circuit is disconnected / the AC breaker is off. The inverter shuts down. The manual warns: if the AC switch is off, do not simply switch it back on – the impedance of the device or external cables should be checked first.

When to call a service technician: If the grid is up and the code stays, contact your installer.
