8.4 Setting the Deactivation Delay
The deactivation delay is the amount of time that must pass from the moment the DC feed-in conditions
are no longer met until the moment the inverter disconnects itself from the power distribution grid.
Requirement:
☐ A communication product that is appropriate for the type of communication used must be
