Compatible grid configurations:
The connection procedure will vary, depending on the grid configuration; the country data set may
have to be set. The following table provides an overview of the compatible grid configurations,
which conductors have to be connected to the inverter to comply with the grid configuration and
which country data set can be 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 country data set
UL1741/2016/120 L-N-L is factory-set.
