Network Installation
The Conext Solar Charge Controller is a Xanbus-enabled device. Xanbus is a
network communications protocol developed by Schneider Electric. The solar
charge controller is able to communicate its settings and activity to other
Xanbus-enabled devices, such as the Conext XW+ inverter/charger, Conext
System Control Panel (SCP), Conext Automatic Generator Start (AGS), and other
charger controllers.
Xanbus connections between multiple solar charge controllers allows information
about each solar charge controller and its associated PV array to be
communicated between all of the solar charge controllers in the system.
Information about the entire system can be displayed on any solar charge
controller LCD in the system.
For example, in a two-solar charge controller system, if solar charge controller #1
is producing 1500 W and solar charge controller #2 is producing 2000 W, both
units display a total system power of 3500 W. The accumulated amp-hours and
kilowatt-hours produced by both units that day is also displayed.
Networked solar charge controllers also share battery temperature information if
a single BTS is connected to a single solar charge controller or Conext XW+
inverter/charger) in the system.
Without Xanbus connections, each solar charge controller in a system will only
display information specific to the unit and its associated PV array.
Network Components
A Xanbus network consists of the following components:
• Xanbus-enabled devices:
• Conext Solar Charge Controller
• Conext XW+ inverter/charger
• Conext Automatic Generator Start
• Conext System Control Panel or Conext ComBox
• Xanbus power supply—When only solar charge controllers are installed, a
Xanbus power supply is required to supply network power. The charge
controller does not provided Xanbus power. The solar charge controller will
communicate with other solar charge controllers, but the units can not supply
network power to any other devices.
In systems that combine solar charge controllers with other Xanbus-enabled
devices, the Conext XW+ provides the required 15 Vdc/200 mA network
power.
• Network cables—Each Xanbus-enabled device is connected by a standard
Ethernet (CAT 5 or CAT 5e) cable, available from any computer supply store.
