Network Installation

The charge controller is a Xanbus-enabled device. Xanbus is a network

communications protocol. The charge controller is able to communicate its

settings and status to other Xanbus-enabled devices, such as Xantrex XW

Hybrid Inverter/Chargers, the SCP, the Xantrex XW Automatic Generator Start

(AGS), and other charge controllers.

Xanbus connections between multiple charge controllers allow information about

each charge controller and its associated PV array to be communicated among

all of the charge controllers in the system. Information about the entire system

can be viewed on the SCP.

For example, in a two-charge controller system, if charge controller #1 is

producing 1500 W and charge controller #2 is producing 2000 W, the SCP

displays a total system power of 3500 W. The accumulated amp hours and

kilowatt hours produced by each charge controller for that day is also displayed.

Networked charge controllers also share battery temperature information if a

single BTS is connected to a single charge controller (or Xantrex XW Hybrid

Inverter/Charger) in the system.

Network Components

A Xanbus network consists of the following components:

• Xanbus-enabled devices: These include the charge controller, the Xantrex

XW Hybrid Inverter/Charger, the AGS, and the SCP. A sample network can

consist of up to three Xantrex XW Hybrid Inverter/Chargers, two charge

controllers, one AGS, and one SCP. When only charge controllers are

installed, up to ten can be networked together.

• Xanbus power supply: The charge controller provides up to 7 W of power on

the Xanbus network to power one SCP, one AGS, and one Gateway, not

including the auxiliary supply. To reduce tare losses at night, you can

configure the charge controller to shut off the Xanbus power supply after

sunset if you do not need device status information when it is not operating.

See “Disabling Power Supplies at Night” in the Xantrex XW MPPT 80 600

Solar Charge Controller Operation Guide for more information.

• Network cables: Each Xanbus-enabled device is connected by a standard

Ethernet (CAT 5 / CAT 5e) patch cable. Do not use crossover cable.
