XW Solar Charge Controller Installation

This manual for use by qualified personnel only
Commissioning
During commissioning, the XW Solar Charge Controller prompts the installer to enter
important system information such as the nominal battery voltage, battery type, and
battery bank capacity. Ensure the system information is available prior to commissioning.
If a XW System Control Panel is present, the XW System Control Panel is intended to be
the configuration interface, so the prompt screens are suppressed. If you prefer to
configure using the prompt screens, disconnect the Xanbus cable connecting the XW
System Control Panel from the XW SCC before powering up for the first time.
Configuration Screens
When power is first applied to the XW SCC, several configuration screens prompt you to
enter the following information:
• A “DC out” (battery) connection, which enables the XW SCC to read and share the
same battery information with other Xanbus-enabled devices that charge or invert
from the same battery bank.
• Battery type: Flooded (default), Gel, AGM, Custom.
If you select Custom, the settings for battery type match the default settings for
Flooded batteries until you reconfigure the settings on the Custom Battery menu.
• Nominal battery voltage of the battery bank connected to the XW SCC.
The XW Solar Charge Controller automatically detects battery voltages of 12 V, 24 V
and 48 V.
• Battery bank capacity, in amp-hours.
Commissioning Units Using a XW System Control Panel
In systems where an XW System Control Panel (SCP) is present, the SCP is intended to
be the configuration interface. For information about SCP navigation and menus, see
Appendix B, “XW System Control Panel Menus” in the
XW Solar Charge Controller
Owner’s Guide .
Commissioning units using an SCP involves three separate procedures:
1. Setting the Device Numbers for all XW SCCs.
2. Configuring Connections and Charger Settings for the first XW SCC.
3. Copying settings from the first unit to the other XW SCC.
To set the Device Numbers for all XW Solar Charge Controllers:
1. Ensure power is applied to the XW System Control Panel.
2. Close the DC disconnect or use a selector switch to apply battery power to all of the
XW SCCs at the same time. When the XW SCCs are powered up, they will detect that
an SCP is already operating on the network, and be ready for configuration through
the SCP. Do not apply PV power at this point.
3. From the Select Device menu on the SCP, select a XW Solar Charge Controller (each
unit should appear as “MPPT60 00” where the 60 stands for 60A, and the 00 is its
device number).
