4.3.1.2.1 Automatic alignment of sensitive parameters
When a multi inverter system is detected, the unit checks for consistency of the set parameters. If the
sensitive parameters are not aligned on all inverters, the display of each inverter shows a message
requesting whether to transfer the configuration of the specific inverter to the entire system. On acceptance,
the sensitive parameters on the inverter where confirmation is given are distributed to all other inverters in
the series.
If there are configurations incompatible with the system, the configuration cannot be aligned from these
inverters.
During normal operation, modification of a sensitive parameter on an inverter will cause automatic alignment
of the parameter on all other inverters without any request for confirmation.
Automatic alignment of sensitive parameters has no effect on all other types of parameter
In the particular case of inserting an inverter with default settings in the series (in the case of an inverter
which replaces an existing model or an inverter with restored factory settings), if the configurations applied,
with the exception of factory settings, are consistent, the inverter with the factory settings will automatically
take on the sensitive parameters of the series.
