On the Connections menu, you can configure PV In (PV input) and DC Conn
(DC output, or the battery bank). If the system has only one battery bank,
leave DC Conn at the default setting. The PV In setting allows you to
differentiate which array is going to which XW SCC. This setting is used for
status reporting only, not for any internal controls. Setting PV In to a non-
default value is optional.
3. Press Exit twice to leave the Connections menu and Multi Unit Config menu.
4. From the Advanced Settings menu, select Charger Settings.
5. Set the Battery Type, Battery Capacity, and any other charger settings
required for your system.
While in the Charger menu, ensure that the Nominal Battery Voltage is set
correctly (it is shown as Batt Voltage and appears as the last item on the
menu). If you select “Custom” for your Battery Type, you can further
configure the Bulk, Absorption, Float and other settings for the charge cycle.
The first unit should now be configured properly for your system.
If multiple units are installed, you can now copy the first unit’s configuration
over to other units.
To copy the XW SCC setup to another unit:
1. On the SCP, press Exit to leave the Advanced Settings menu and view the
Select Device menu.
2. On the Select Device Menu, select the next XW SCC for configuration.
3. On the Advanced Settings menu, select Copy From, then select the XW SCC
you want to copy from. You should select the unit with the device number that
matches the first unit you configured.
4. Press Enter.
The settings are automatically copied from the selected unit.
5. Uncover the PV array and/or apply power with the disconnect or selector
switch.
The XW SCC starts up in sleep mode and waits for a short period to determine
that the input voltage is greater than the output voltage. After the input voltage
exceeds the output voltage by the required margin for 10 seconds, the unit begins
operating.
Note:
The Copy From command will not give you any indication that it has completed
its task. However, you can quickly check for yourself that the charger settings you have
chosen have been copied properly by viewing some of the settings you originally
configured.
