Grid standard
Before wiring the inverter, the installer needs to determine the grid configuration
that the inverter will be connected to. The Growatt inverter is default set for utility
interconnection with 240Vac from factory. However, you can choose the Net MODEL
through the LCD to set the inverter to be fitted the commonly used utility
configuration types shown in the figure 5.6.3.
Based on the local grid standards, it is possible to select different connection types.
The available configurations are shown in the following table:
NOTE: in the inverter wire box,AC terminal pin is written as L1,L2 and PE,not the pin
number,that just for the default net model.
if you connect to other net model,you much connect the wire to the terminal pin
number exactiude as above.

WARNING
If several Growatt inverter are installed in a three-phase AC grid. it is
recommended to distribute the inverters between the phases in order
to reduce the power unbalances between the phases. Always refer to
the local standards.
WARNING
si plusieurs Growatt inverter sont installés sur un réseau électrique à
courant alternatif à trois phases. Il est recommandé de distribuer les
onduleurs entre les phases pour réduire les déséquilibres de puissance
entre les phases. Toujours vous référer aux normes locales.
