Network Installation
The Xantrex XW-MPPT60-150 is a Xanbus
®
-enabled device. Xanbus is a
network communications protocol developed by Xantrex. The XW SCC is able to
communicate its settings and activity to other Xanbus-enabled devices, such as
the XW Series Inverter/Charger, the XW System Control Panel (SCP), XW
Automatic Generator Start (XW-AGS), and other XW Solar Charge Controllers.
Xanbus connections between multiple XW SCCs allows information about each
XW SCC and its associated PV array to be communicated between all of the XW
SCCs in the system. Information about the entire system can be displayed on any
XW SCC LCD in the system.
For example, in a two-XW SCC system, if XW SCC #1 is producing 1500 W and
XW SCC #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 XW SCCs also share battery temperature information if a single BTS
is connected to a single unit (XW SCC or XW Inverter/Charger) in the system.
Without Xanbus connections, each XW SCC 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—these include the XW SCC, the XW Hybrid
Inverter/Charger, XW-AGS, and SCP. The network can consist of up to three
XW Hybrid Inverter/Chargers, two XW SCCs, one XW-AGS, and one SCP.
When only XW SCCs are installed, up to 10 units can be networked together.
•
Xanbus power supply—When only XW SCCs are installed, no Xanbus power
supply is required to supply network power. The XW SCCs will communicate
with other XW SCCs, but the units can not supply network power to any other
devices.
In systems that combine XW SCCs with other Xanbus-enabled devices, the
XW Hybrid Inverter/Charger 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 Xantrex or any computer
supply store.
•
Network terminators (Figure 2-12)—the Xanbus network must be properly
terminated at each end to ensure the communication signal quality on the
network. Network terminators plug into network ports on Xanbus-enabled
CAUTION: Equipment damage
Do not use crossover cable.
