3.6.2 DC Input Groups
The configuration of the DC input to the inverters provides several different ways to monitor DC input power
and input current. The number of DC Input Groups (maximum eight) is set in the Inverters > Group Mapping
screen and monitored as a unit in the View Group Status screen. The following table gives examples of pos-
sible configurations.
Monitoring DC Source
Bulk Assign all inverters to DC Input Group 1.
Dual Input For example:
Assign all the inverters in column 1 & 2 to DC Input Group 1.
Assign all the inverters in shelves 3 & 4 to DC Input Group 2.
Quad Input For example:
Assign all the inverters in column 1 to DC Input Group 1.
Assign all the inverters in shelves 2 to DC Input Group 2.
Assign all the inverters in column 3 to DC Input Group 3.
Assign all the inverters in shelves 4 to DC Input Group 4.
