6.4.2 Group Mapping and View Group Status
Configuration of AC Input Groups
Use this interface to assign inverters to input phases (
Inverters > Group Mapping ).
The logical approach is to match the configuration of inverters in the AC Input Groups to the configu-
ration of inverters in the AC Output Groups as shown in Figure 40.
The AC Output Groups of an inverter in the ON state cannot be changed. The radio buttons for that
inverter AC output group remain disabled until the inverter is turned OFF . All inverter modules can be
turned ON or OFF simultaneously with the button under the System Power heading.
The number of columns increase when groups are added and decrease when groups are removed.
Adding/removing groups (columns) may take a few seconds to update the screen. Changing the ra-
dio buttons (rows) will also take time to apply the changes; for example, approximately two seconds
for one inverter and up to ten seconds for the maximum 32 inverters.
