ID02The power grid voltage is too low

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

In plain words (editorial)

The grid voltage is too low for the inverter. If the alarm occurs frequently, the manual says to check whether the grid voltage and frequency are within the acceptable range; if they are, check the AC circuit breaker and the AC wiring of the inverter.

When to call a service technician: If the grid is outside the range, or wiring checks are needed, contact the installer or technical support.
