Introduction

Chapter 1, “Introduction” contains information about
the features and functions of the Communications
Gateway.

This chapter covers the following topics:

• “Gateway Overview”

• “External Features”

• “Types of Gateway Networks”

Introduction

1–2 975-0330-01-01

Gateway Overview

The Communications Gateway is the central component for a residential
power monitoring system. The Gateway communicates with Xantrex GT
Solar Inverters and XW Hybrid Inverter/Chargers and transmits a unified
view of system performance to a computer-based power monitoring
application.

On one side, the Gateway directly communicates with a Xantrex inverter
using Xanbus™, a CAN-based network communication protocol
developed by Xantrex. The Gateway converts Xanbus messages to
Modbus messages, and transmits the converted inverter performance data
for monitoring. On the other side, the Gateway’s WiFi/Ethernet module
provides an interface to monitor system performance on a personal
computer. Computer-based monitoring can be performed on your Local
Area Network or using the Internet from any location.

The Gateway features include a standard plug-in WiFi/Ethernet module
with 10/100 Base-T or 802.11b/g, and:

• Embedded web services to support Yahoo! W idgets. Xantrex provides
a Solar Monitor Widget to display data transmitted by the Gateway.

• Embedded web page for configuring the Gateway and upgrading
device firmware.

The Gateway logs and transmits performance data such as:

• Power system energy production

• Individual inverter energy production

• Energy production history—daily, weekly, monthly

• Inverter faults.

To view this production data, you must install the Xantrex Solar Monitor
Widget and configure the Gateway to communicate with your computer
or computer network. Other means of viewing Gateway-transmitted data
will be available from Xantrex in the future. For more information about
Gateway data storage, see “History Data Storage” on page A–2.

Note: The Gateway provides performance data only from the time it is

connected to your power system. The Gateway cannot be calibrated to match
existing power production totals for a power system that has been operating
without a Gateway. When connected to an existing power system, the Gateway
power production totals will differ from the totals displayed by older inverters
or devices in the system.

world.

For more information, see the Gateway configuration web page
(“Viewing the Configuration Web Page” on page 3–2) and “Power
System Monitoring on the Internet” on page 3–20.

If you simply want to monitor your power system on your home network,
you do not need to change your firewall settings.

CAUTION: Computer Security Risk

Changing your router’s firewall settings to allow port forwarding can potentially
leave your home network open to attacks from external computers. Do not
change your firewall settings unless you are absolutely sure of how to do it
correctly. The PORT Forward web site (www.portforward.com) has collected
information on how to configure most popular routers. Xantrex does not provide
any guarantees as to the security of your network if you follow the advice
provided at the PORT Forward web site. Use at your own risk.

Installation

Chapter 2, “Installation” contains information and
procedures to install the Communications Gateway.

Gateway installation includes mounting the Gateway,
then connecting it to a computer network and to the
Xanbus network.

Installation

2–2 975-0330-01-01

Installing the Gateway

This chapter assumes that one or more inverters are already installed, and
that multiple inverters are already connected with network cables. For
more information about installing a multiple-inverter network, see:

• For GT Inverters: “Communications Wiring for Multiple Inverters” in
the Solar Inverter Owner’s Manual

• For XW Hybrid Inverter/Chargers: The XW Power System
Installation Guide.

Installing the Gateway consists of the following steps:

1. Choosing a Location.

2. Mounting the Gateway.

3. Connecting the Gateway to a router (your local area network) or
computer.

4. Connecting the Gateway to the Xanbus network.
Connecting the Gateway to the Xanbus network also applies power to

the Gateway.

5. Installing Yahoo! Widgets (also known as Konfabulator or Yahoo!
Widget Engine) and Solar Monitor Widget on your computer.

The Solar Monitor Widget displays power system performance data
transmitted from the Gateway.

WARNING: Shock and energy hazards

Connections to other equipment may require accessing wiring compartments
containing circuits that are shock or energy hazards. In such cases, ensure that
sources of power are disconnected. Installation should be done only by a
qualified installer or electrician.

Important:

Apply power to the Gateway only after connecting it to the local
area network in the previous step. This ensures that the Gateway can acquire an
IP address quickly, and does not first acquire a default address that it must reject
after a time-out period.

Installing the Gateway

975-0330-01-01 2–3

Choosing a Location

Choose a clean, dry, easily accessible location. Indoor installations are
recommended. For outdoor installations, mount the Gateway inside a
weatherproof enclosure. A recommended outdoor mounting enclosure is
available from Xantrex (part number 864-0500).

Minimum
clearance

To comply with FCC and Industry Canada regulations, the Gateway must
be installed in a location where the antenna is at least 8 inches (200 mm)
away from people and any other antenna.

Maximum
distance
between
devices

Distance and orientation are important factors to consider when installing
a wireless network. In testing, the Gateway has delivered acceptable
performance under optimal conditions up to 300 feet (90 meters) away
from another wireless device. Many factors can affect network
performance, including house construction, antenna orientation, and
distance between devices.

For best performance, a wired Ethernet connection between the Gateway
and the Internet router is recommended.

Important:

During Gateway configuration, you must connect the Gateway to
the router or computer with an Ethernet cable. After the Gateway has established
network connections, you can configure the Gateway for wireless mode, after
which you can remove the cable between the Gateway and the router.

Installation

2–6 975-0330-01-01

Connecting the Gateway to a Router or Computer

To connect the Gateway to a router:

u Connect a standard Ethernet cable from the Gateway Ethernet port to

an open network port on your router.
Do not connect the Gateway to the router port labeled “Internet” or

“WAN.”

To connect the Gateway directly to a computer:

u Connect a crossover cable from the Gateway Ethernet port to an open

network port on your computer.

Connecting the Gateway to the Xanbus Network

A Xanbus network consists of the following components:

• Xanbus-enabled devices—these include the Gateway, the GT
Inverter, the XW Series Inverter/Charger, XW Automatic Generator
Start (AGS), System Control Panel (SCP), and XW Charge
Controller. The maximum number of devices on the network depends
on the type of device. For example, the Gateway can monitor a
network consisting of up to 20 G T Inverters (up to five GT Inverters if
a GT Solar Inverter Monitor is installed) or an XW Power System
with up to three XW Inverter/Chargers, two Charge Controllers, an
AGS, SCP, and Gateway. (This is the current maximum size of an
XW Power System. Future XW releases will allow more than three
XW Series Inverter/Chargers to operate in a Xanbus network.)

In systems that combine GT and XW inverters, treat an XW Series
Inverter/Charger as the equivalent of four GT Inverters. XW inverters
transmit up to four times as much network data as a GT Inverter.

• Xanbus power supply—the inverter or inverter/charger provides
network power.

Important:

During setup, a wired connection between the Gateway and the
router is required. During configuration, the Gateway can be switched to wireless
mode and the network cable can be removed. See “Configuring Wireless Mode”
on page 3–12.

Important:

Connecting the Gateway to the Xanbus network also applies
power to the Gateway. Before making the final connection to the Gateway, see
“Applying Power to the Gateway” on page 2–11.

Installing the Gateway

• Xanbus cables—each Xanbus-enabled device is connected by a
standard Ethernet (CAT 5e) cable. A 10 foot (3 meter) network cable
is included with the Gateway. If more cables or a different length are
required, these standard cables can be purchased from Xantrex or any
computer supply store.

• Network terminators (Figure 2-2)—the Xanbus network must be
properly terminated at each end with network terminators. If the
network is not properly terminated, signal quality is degraded and
performance on the network is reduced. Permanent configuration
without terminators is not supported by Xantrex. One terminator is
included with the Gateway. Depending on your network layout, this
terminator may need to be inserted into another device elsewhere in
the network.

Important:

If the Gateway is connected to a single GT Inverter manufactured
before spring 2008, then an external Xanbus power supply must be added to the
system. XW Hybrid Inverter/Chargers or any multiple GT Inverter installation
can provide sufficient network power.

CAUTION: Equipment damage

Do not use crossover cable. On crossover cable, the order of color-coded wires at
each end of the cable is different.

Network Layout

Xanbus-enabled devices are linked with separate lengths of Xanbus cable,
as shown in Figure 2-3.

T o ensure communication signal quality, each end of the network must be
terminated. The Xanbus-enabled devices at each end of the network must
have a male terminator inserted into their open network ports.

If the Gateway is the last device on the network, the open Inverter port on
the Gateway must be terminated. See Figure 2-3.

Guidelines for Routing the Network Cables

To ensure maximum performance of your network, follow these
guidelines when routing the network cables.

• Route the cables away from sharp edges that might damage the
insulation.

Figure 2-3

Network Layout Diagram

:

WARNING: Shock hazard

Do not route the network cables in the same conduit as the AC and DC power
cabling. When connecting and routing the network cable in the inverter wiring
box, make sure the network cable is physically separated from the AC and DC
power cables and any bare live parts by a barrier or by wire routing and securing
means.

• Allow for some slack in the cable tension.

• Do not staple the cable outside the inverter with metal cable staples.

Use the appropriate hardware fasteners to avoid damage to the cable.

Connecting the Gateway to a GT Inverter

The GT Inverter is equipped with two Xanbus (RJ-45) network ports
inside the wiring box. See Figure 2-4. Follow the guidelines for
connecting devices and terminating the network as described in “Network
Layout” on page 2–8, and in “Communications Wiring for Multiple
Inverters” in the GT Inverter Owner’s Manual.

CAUTION: Unpredictable device behavior

Do not connect one end of the network to the other to make a ring or loop.

CAUTION: Equipment damage

Although the cables and connectors that connect the Gateway to the Xanbus
network are identical to Ethernet cables and connectors, the communication
interface is not Ethernet. It is based on CAN bus and also supplies the Xanbus
network devices with DC power. The DC power in the Xanbus network is not
compatible with Ethernet. Personal computers or routers will be damaged if
connected directly to powered Gateway Inverter ports. The Gateway can be
damaged if a powered Xanbus cable is connected to the Ethernet port.

Applying Power to the Gateway

The Gateway gets its power from the Xanbus network through the
network cable. When applying power to the Gateway by connecting the
network cable, ensure that the Xanbus network itself has power. The
inverter or inverter/charger supplying power to the Xanbus network must
be operating.

If connecting the Gateway to a GT Inverter, ensure that the GT Inverter
DC/AC disconnect switch is in the ON position. The GT Inverter LCD
should be on.

If connecting the Gateway to an XW Hybrid Inverter/Charger , ensure that
the inverter/charger is operating. The Inverter Information Panel should
be illuminated.

To apply power to the Gateway:

u Plug the Xanbus network cable from th e network into an Inverter port

on the Gateway.

After connecting the Gateway to the Xanbus network, the Gateway
performs a power-up test. The Inverter LED lights up green for 1 second,
the Modbus LED lights up yellow for 1 second, then the Inverter LED
lights up red 1 second. During normal operation the Inverter LED blinks
green and the Modbus LED blinks occasionally.

The Inverter LED blinks green if the Xanbus network is working
properly. It blinks yellow or red if there is a problem with the network.
The Modbus LED flashes when an external device requests data from the
Gateway.

Adding Devices to the Network

The Xanbus network is expandable. Before installing additional inverters
or other network devices, follow these guidelines.

• Close the Solar Monitor Widget if it is running. If the Widget detects

a device dropping off the network due to a disconnected networ k
cable, it issues an error message.

• Remove network power from the Gateway by unplugging the Xanbus

network cable from the Gateway.

• Do not apply power to the Gateway until the new network devices are

completely connected.

Configuring the Gateway

You can configure the Gateway using a web page embedded in the
Gateway firmware. This web page allow you to configure parameters for:

• basic networking

• wireless networking

• network time protocol

• email messages for energy harvest and system performance.

You can also use the configuration web page to upgrade firmware for
network devices, including the Gateway.

The configuration web page itself has extensive embedded help. This
chapter contains additional information and advice.

Viewing the Configuration Web Page

To view the configuration web pa ge, you must find the device IP address
of your Gateway. The easiest way to find the Gateway on your network is
to run the Solar Monitor Widget after applying power to the Gateway.
The Widget has an automatic device discovery feature that functions on
most computers and small home-based computer networks. After the
device discovery process finds the Gateway, you can use the Widget to
view the Gateway configuration web page. See “Using the Solar Monitor
Widget” on page 3–3.

If you have multiple Gateways installed on the same network, the device
discovery process attempts to locate them all. You can use the Widget to
check which Gateways have been located (see the Solar Monitor Widget
User Guide). If the device discovery process does not work for one or
more Gateways, you must find and assign the Gateway IP addresses
manually. See “Finding the Gateway IP Address Manually” on page 3–5.

Computers operating on a company domain (not a home workgroup)
often have the device discovery disabled for security reasons. If this is the
case, you will have to manually determine the Gateway’s IP address in
order to view the configuration web page.

Software firewalls, such as ZoneAlarm or Windows Firewall, may also
prevent device discovery from running. If possible, add the device
discovery process to the firewall’s exception list so that it is allowed to
function. If you can’t add device discovery to the exception list, you will

Finding the Gateway IP Address Manually

To view the configuration web page on a protected domain:

1. Open your web browser and enter your router’s IP address into the

Address bar. Check your router documentation if necessary. Usually
this address is 192.168.0.1 or 192.168.1.1, unless it was changed
when the router was installed.

The router log-in page appears.

2. Enter your user name (usually “admin”) and password. Check your

router documentation if necessary.

3. Navigate to the router page that lists all devices connected to your

router. For example, on the Linksys WRT300N router this can be
accessed under “Status—Local Network” then by clicking on “DHCP
Client Table.” Other routers may list devices under “Hostname.”
Some routers do not show this information at all. If that is the case,
follow the directions in “Finding the Gateway IP Address with No
Router in the System” on page 3–7.

4. The router page should list your computer name and

“POWERSYSTEM” (the default Gateway name) along with an IP
address for each. In Figure 3-4, the Gateway IP address is

192.168.7.101. Note that this address can change for several reasons,
including turning your router on and off, or disconnecting and
reconnecting devices to your router.

to copy some of these values from some of your existing equipment.

You will need to configure Gateway networking parameters to enable
power monitoring from any location via the Internet. For more
information, see “Power System Monitoring on the Internet” on page 3–

20.
MAC Address Shows the Media Access Controller (MAC) address of

the Ethernet or WiFi port on the Gateway. The MAC address cannot be
changed.

Get Address Dynamically Select the Get Address Dynamically check
box to configure the Gateway to request an address for use on the
network. Most home routers can supply an address automatically to
devices on the network. If your router is configured this way, select the
Get Address Dynamically check box.

Note that if you wish to use the Widget to access the Gateway from a
location outside your local area network, such as your workplace or an
Internet cafe, you will find it easier to manage if a static address is set.
The easiest way to do this is to first configure the Gateway for a dynamic
address so that all the addresses get filled in, then clear the Get Address
Dynamically check box and configure only the new static Gateway IP
address outside the range of addresses supplied by your router.

Xantrex Gateway Address The Xantrex Gateway Address is the IP
address that routers or computers use to connect to the Gateway. If
necessary, enter a static IP address that network devices can use to
connect to the Gateway.

If your home router does not automatically supply addresses to devices on
the network, or if you want the Gateway to have a specific address, clear
the Get Address Dynamically check box and enter a static IP address.

Internet Gateway Address This is the IP addre ss of the router,
computer, or modem to which the Gate way is connected. Enter an address
used by devices on the local network to get out to the Internet.

If your home router cannot supply addresses to devices on the network, or
if you want the Gateway to have a specific address, clear the Get Address
Dynamically check box and enter a static IP address here.

Name Server Address Enter an address used by devices on the local
network which translates names to IP addresses.

Configuring Wireless Mode

When configuring wireless network parameters, you must enter as m uch
identical information from your existing network as possible. Before
configuring wireless mode, view and record the network wireless settings
you are using with your router or computer.

If the Gateway loses connection while configuring wireless mode, the
Gateway may have to be reset. Follow the procedure described in
“Resetting the Gateway to Factory Defaults” on page 3–19. Before
resetting the Gateway, ensure that the Gateway and your computer are
connected with an Ethernet cable.

Network Interface. Configures the Gateway to use either a wireless or
a hard-wired Ethernet connection for the communications network. Select
“Wireless” or “Wired.”

Network Type. Configures the type of wireless connection between the
Gateway and your computer. When a wireless router is the connection
point between the computer and the Gateway, select “Infrastructure.”
Most installations will use “Infrastructure” mode. For a direct connection
between the Gateway and a wireless-equipped computer with no
connection to the Internet (see Figure 1-8 on page 1–7), select “Ad-Hoc.”
“Ad-Hoc” networks also require a radio channel to be set.

Network Name (SSID). Sets the name of the wireless network, or
Service Set Identifier (SSID). The SSID is case sensitive and is only used
in wireless mode. Set this value to be the same as your existing home
network SSID.

An SSID is a unique identifier attached to all packets sent over a wireless
network in order separate one network from another. All devices
connecting to the same wireless network must use exactly the same SSID.

Radio Channel. Sets the radio channel that your wireless network uses
to send messages between devices. Select a radio channel when Network
Type is set to Ad-Hoc.

If possible, select a channel unused in your neighborhood. You can use
the NetStumbler application (www.netstumbler.com) to help find an
unused channel. If all channels are already in use, select the channel
which has the lowest radio signal power level. NetStumbler displays
signal power levels for every channel it detects.

Using the Configuration Web Page

975-0330-01-01 3–13

Note that only channels 1, 6, and 1 1 are clear channels. All other channels
overlap with 1, 6, 11, and each other. If you see channels 1, 2, 3, 4, 5, and
6 in use in a neighborhood, then choose channel 11 to get a clear channel
because channels 7 through 10 will overlap with channel 6, reducing your
data transmission speed.

Security. Selects the security type in use on your wireless network. Set
this value to be the same as your existing home network.

Wired Equivalent Privacy (WEP) is an early scheme to secure wireless
networks. It provides a level of security which may prevent casual
snooping.

WiFi Protected Access (WPA) is a class of systems to secure wireless
networks. It can provide good security as long as a good pass-phrase is
chosen for the encryption key.

Authentication. Configures whether the network uses authentication or
not. Set this value to be the same as your existing home network.

For WEP security, “Open/None” means that the wireless network does
not perform any authentication. “Shared” means that the wireless network
uses a key entered on both the Gateway and the router to authenticate
each network packet.

For WPA security, only “Pre-Shared Key (PSK)” can be selected, which
ensures that each network packet is authenticated.

Encryption Mode. Configures the level of encryption used on the
wireless network. Set this value to be the same as your existing home
network.

For WEP security, you can select the encryption strength of either “64
bits” or “128 bits,” where “128 bits” provides a stronger encryption.

For WPA security, only “TKIP” can be selected, which ensures that the
encryption dynamically changes keys to provide stronger encryption.

Key Type. Configures the type of the key for either a user readable
passphrase or a set of hex numbers. Set this value to be the same as your
existing home network.

Important:

Do not configure the radio channel if your Network Type is
“Infrastructure.” If you change the radio channel on your router while in
Infrastructure mode, the Gateway loses connection. To enable the Gateway to
find the router again, remove and reconnect Gateway power by unplugging and
reconnecting the Xanbus network cable.

Configuration

3–14 975-0330-01-01

Encryption Key. Configures the encryption key used in the wireless
network. Set this value to be the same as your existing home network.

Enter the key as hexadecimal numbers if the hex Key Type was selected
above. Enter the key as a string of characters if the passphrase Key Type
was selected above. A passphrase of more than 20 characters is
recommended. Spaces and punctuation characters are permitted.

Configuring Network Time

You can configure the Gateway to use a network time protocol (NTP)
server on the Internet. Network time read from the Internet is very
accurate.

Universal Coordinated Time (UTC, sometimes referred to as Greenwich
Mean Time or GMT) is the default time provided by NTP servers. When
using an NTP server, you must enter a Time Zone Offset to shift UTC to
your local time.

You can also configure the Gateway to read time from a computer on your
local network if the computer has been configured as a NTP server. It is
best to use a computer on your local network (if available) so that the
Gateway and all computers on the network are synchronized.

If you are unable to contact an NTP server, or are not connected to the
Internet, you can set the date and time manually using Local Date and
Local Time. Local Date and Local T ime use the Gateway internal clock as
a reference, which is not as accurate as time from an NTP server.

Time Zone Offset Sets the local time zone offset from UTC/GMT.
Enter the number of hours your local time is offset from UTC/GMT. For
locations west of Greenwich, England, the offset should be negative. For
locations east of Greenwich, the offset should be positive. Adjust for
daylight savings time if it applies in your area.

When updating the Time Zone Offset and no other Network Time
settings, select Update Offset Only before changing the Time Zone
Offset.

Use Local Settings When selected, Local Date and Local Time settings
become available. When cleared, you can configure the Gatewa y to u se a
network time server.

Important:

Setting an incorrect Network Name (SSID), security mode, or
encryption key causes the Gateway to lose its connection with the network. If the
Gateway has lost its connection in this manner, it must be reset to factory default
settings.

Using the Configuration Web Page

975-0330-01-01 3–15

Local Date Sets the date when the Gateway is not connected to an NTP
server.

Local Time Sets the time when the Gateway is not connected to an
NTP server.

Time Ser ver Sets the name or IP address of a network time server. Set
Time Server to any single NTP time source. It can be set to a randomly
selected server such as pool.ntp.org, to a server provided by your Internet
service provider, or to a computer on your local network if it has been
configured as an NTP server.

Server Type Selects the type of time server. Select Domain if you use
the name of the server, such as pool.ntp.org. Select IP if you know the
numerical IP address of the server.

Update Time Click Save and Update to save the Gateway time
configuration. If you have entered a server name or IP address, clicking
Save and Update also causes the Gateway to update the time using the
selected NTP server.

Important:

The Gateway may send a Daily Harvest email when the Local

Date is manually set.

Configuration

3–16 975-0330-01-01

Configuring Email

You can configure the Gateway to send Energy Harvest and System
Alarm email to several different email addresses.

Types of
messages

The Gateway can send four types of messages:

•Alarm

• Daily Harvest

• Weekly Harvest

• Monthly Harvest
Mail Server Sets the name of the network mail server. Enter the server

name that was supplied by your Internet service provider. This should be
the same mail server used for the email program already on your
computer; for example, smtp.isp.net.

Server Type Selects the type of email server. Select Domain if you use
the name of the server, such as smtp.isp.net. Select IP if you know the
numerical IP address of the server.

To configure each type of message:

1. Enable the message type. You can configure the Gateway to send one

or more message types.

2. Add an address list. For each enabled message type, enter one or

more email addresses (separated by commas) to receive email from
the Gateway.

3. Add a custom message for each enabled message type (optional). You

can add text (up to 200 characters) to be included in each email from
the Gateway. This text might include system information such as
inverter model and solar array specifications, or additional contact
information.

4. Click Send Email to send a test message to each address in the

address list. This helps ensure that the address list, message, and mail
server configuration are correct.

Note: The basic information you entered under “Home” is also included

in any email messages the Gateway sends.

Using the Configuration Web Page

975-0330-01-01 3–17

Alarm
messages

The Gateway sends an alarm message to alert you whenever a fault occurs
in the power system. If a fault occurs while the Gateway is reset or has
power removed, the Gateway sends an alarm message when the Gateway
is operating again. The Gateway cannot determine if the fault occurred
before or while it was powered off, so it will always send an alarm
message at startup when there is either an active or logged alarm in the
system.

Under some conditions, the Gateway sends a series of alarm messages
that may be caused by an intermittent fault, or by the Gateway being
repeatedly reset. If the messages become a nuisance and the fault does not
clear itself, disable automatic alarm messages and contact your system
installer or dealer.

Harvest
messages

Energy Harvest email messages contain detailed power production data
and can be sent every day, once a week, or once a month.

The Gateway sends harvest email at the same time each day. In a
multiple-Gateway system, each unit sends harvest email at a different
time. This randomized outgoing email time prevents many Gateways
from sending email at the same time. This could cause a distributed denial
of service (DDOS) if every Gateway sent email to the same address.

Upgrading Device Firmware

To upgrade the firmware for devices in the system, click Upgrade
Device. You can then select the device you want to upgrade and browse

for the latest firmware load. Firmware loads are available from from the
Xantrex Web site at www.xantrex.com/gateway or your dealer.

Figure 3-9

Configuring Email

Important:

The Gateway only makes one attempt to send email. If there is a

problem sending the email, the Gateway does not retry at a different time.

Configuration

3–18 975-0330-01-01

The time it takes to upgrade firmware for a device can vary depending on
the device. The Gateway configuration web page displays a progress
indicator during the firmware upgrade process. The Modbus/RS485 LED
is on steadily during a firmware upgrade.

The Upgrade Device section of the configuration web page displays the
current firmware revision of the:

• Gateway Firmware

• Gateway Bootloader. You cannot upgrade the Gateway bootloader.

• Network Firmware—the internal Lantronix wireless networking

module

• Web Page Version—the configuration web page.

Upgrading the
Gateway

Two types of upgrade files are available for the Gateway.

1. WEB-xx.xx-YY.wie (YY is a two-letter language abbreviation. For

example, WEB-01.01-ES.wie is the Spanish file). This file updates
the Gateway configuration web page language. Separate files for each
language are available on the Gateway Quickstart CD. This file
enables you to configure the language on the web page without
performing a full Gateway upgrade, which can take several minutes.
For future configuration web page upgrades, download the WEB­xx.xx-YY.wie or corresponding GW-xx.xx-YY.wie file (see point 2)
from the Xantrex web site.

2. GW-xx.xx-YY.wie (YY is a two-letter language abbreviation. For

example, GW -01.01-ES.wie is the Spanish file). This file updates the
Gateway firmware, the network firmware, and the configuration web
page. Separate files for each language are available on the Gateway
Quickstart CD and (for future updates) at www.xantrex.com/
gateway.

Important:

Do not interrupt network power during the upgrade process. Loss
of power or communication during an upgrade may cause an unrecoverable error
in the wireless networking module.

Important:

Close the Solar Monitor Widget before upgrading Gateway
firmware or performing any action on the Upgrade Device page. Do not start the
Widget until the firmware upgrade is complete.

Resetting the Gateway to Factory Defaults

975-0330-01-01 3–19

Resetting the Gateway to Factory Defaults

Resetting the Gateway to factory defaults resets all configuration settings
and the password. For example, if the Gateway was configured for
wireless operation, the reset procedure will return it to wired operation.

After a reset, the Gateway does not clear any of its power harvest history.
The Gateway may have to be reset when configured improperly. If the

Gateway has spontaneously lost its network connection without any
configuration changes taking place, the connection can usually be re­established by removing and reconnecting Gateway power (unplugging
and reconnecting the Xanbus network cable). If removing and
reconnecting Gateway power doesn’t work, then reset the Gateway to its
factory defaults as described below.

To return the Gateway to its factory default settings:

1. Close the configuration web page if it is open.

2. Remove power from the Gateway by unplugging the Xanbus network
cable from the Gateway Inverter port.

3. If the Gateway was previously configured for wireless operation,
connect an Ethernet cable between the Gateway Ethernet port and
your router or computer.

4. Use a pen or small screwdriver to press and hold the Reset button.

5. While holding the Reset button, reconnect the Xanbus network cable
to the Gateway Inverter port.

6. Hold the Reset button for an additional three seconds.

7. Release the Reset button.

8. View the Gateway configuration web page and reconfigure the
Gateway.

Power System Monitoring on the Internet

In order to view power system performance data from any location via the
Internet, you must change your router firewall settings to allow “port
forwarding.” The PORT Forward web site (www.portforward.com) has
collected information on how to configure port forwarding for most
popular routers.

If you want to monitor your power system on your home network only,
you do not need to change your firewall settings.

To configure the Gateway, router and Widget for power system
monitoring on the Internet:

1. View the Gateway configuration web page.

2. On the Gateway configuration web page, click Network
Configuration.

3. Clear the Get Address Dynamically check box.

4. Change the last field in the IP address to a number that is outside the
DHCP server IP Address Range. You can find this address range on
your router’s configuration page. Do not use 0, 255, or the same
number your router uses (usually 1).

CAUTION: Network security risk

Changing your firewall settings to allow port forwarding can potentially leave
your home network open to attacks from external computers. Do not change your
firewall settings unless you are absolutely sure of how to do it correctly. The
PORT Forward web site (www.portforward.com) has collected information on
how to configure most popular routers.
Xantrex does not guarantee the security of your network if you follow the advice
provided at the PORT Forward web site. Use at your own risk.

d) In Device IP address, fill in the external IP address of your home

network.

e) Ensure Device Port is set to the same port number you selected in

step 10 c).

f) Click Save.

IP Address
Issues

The external IP address that your Internet service provider (ISP) assigns
your home router may change from time to time. This change in external
IP address prevents the Widget from locating your home network from a
remote location.

If your ISP assigns a temporary IP address for your router, you could try a
dynamic domain name system (DDNS) service to assign a domain name
to your router. This service can automatically handle the changes to your
ISP-supplied address. Many routers support DDNS through services like
www.dyndns.com. You can configure these routers to automatically
update the service when your ISP changes your address.

Note: If you are familiar with this procedure and are already running an

Internet-accessible web server on your home network, you may want to
choose a port other than 80 in order to not conflict with the existing service.
