4.14 Configuring the Country Data Set
As standard, the inverter is meant for connection to a utility grid with a 208V wye connection or a
240V split-phase system, and the associated country data set UL1741/2016/120 is factory-set.
If the default country data set does not correspond with the grid configuration, the country data set
can be adapted to the connected grid configuration.
