Introduction
XW Solar Charge Controller
The XW Solar Charge Controller (FGA # 865-1030) is a 60 amp charge controller with
integrated PVGFP and separate Battery Temperature Sensor. The XW Solar Charge
Controller can be used with 12-, 24-, 36-, 48-, and 60-volt DC battery systems. However,
the XW Inverter/Charger can only work at 24 or 48 volts depending on the model. When
the XW Solar Charge Controller is used with the XW Inverter/Charger, it is limited to 24or 48-volt battery banks. The XW Solar Charge Controller will automatically detect the
24- or 48-volt settings.
Figure 1-6

Clearance Requirements
Mounting
The XW Power System is designed to be mounted on a vertical surface. The supporting
surface must be strong enough to support a minimum of 500 pounds (227 kg). To facilitate
installation, a wall mounting plate (Xantrex p/n 210-0462-01-01) is provided for each XW
Inverter/Charger and XW Power Distribution Panel. The mounting plate and hardware on
the XW Inverter/Charger and XW Power Distribution Panel are designed to meet
standards for structural and seismic stability. When properly installed, the system also
meets Section 59 of UL 1741 for Static Loads.
975-0239-01-01 2–3
Inverter/Charger Installation
Step 1: Installing the Mounting Plate
Each XW Inverter/Charger and XW Power Distribution Panel requires a separate
mounting plate. This bracket is first attached to the wall, then the inverter/charger or
distribution panel is attached to the wall bracket.
The wall bracket is attached to the wall with lag bolts or other fasteners, provided by the
installer. A minimum of four ¼-inch diameter fasteners are required. The fasteners must
be sufficiently strong to support 500 pounds.
The wall bracket has mounting holes spaced 16 inches (40 cm) apart and is designed to
span two wall studs spaced 16 inches on-center. Additional mounting holes are also
provided for flexibility in mounting options. If the wall does not have 16-inch on-center
studs, the installer will need to provide adequate supports for the brackets. For example, a
sheet of plywood can be attached to the wall, and the wall brackets can then be attached to
plywood.
Both the XW Inverter/Charger and XW Power Distribution Panel use the same wall
bracket. The brackets are designed to interlock (as shown in Figure 2-3), so that additional
mounting plates are easily installed without additional measuring or levelling.
The type of fastener required to secure the mounting plate varies according to the vertical
surface and wall structure of your installation location.

Inverter/Charger Installation
Step 4: Wiring the Inverter
This section provides procedures for making AC and DC connections between the XW
Inverter/Charger and the power distribution panel using the cables that are pre-installed in
the distribution panel. This section also assumes that the XW Conduit Box was installed in
the previous section.
For diagrams and information about installing the inverter/charger without the XW
Conduit Box and XW Power Distribution Panel, see Appendix C.
Important:
Communication and signal cables must be segregated from all DC and
AC wiring. Therefore, a small raceway has been included in the design of both the
XW Power Distribution Panel and the XW Conduit Box to separate the
communications cables from the power cables. This is a small raceway run built into
the bottom of both the XW Power Distribution Panel and the XW Conduit Box and is
held in place by a single screw at the top of the raceway.
Installation Tip Before making the AC or DC cable connections, route the communications cables through
the raceway, but do not connect them to their components until after all the inverter
connections are made. Once the AC and DC connections are made the run becomes
difficult to access. Use different colors for the communications cables (or cable tags) to
help make them easier to identify.
Route the communications cables for any
accessories being installed BEFORE
making AC or DC Connections.
Do not connect to the
XW Automatic
Generator Start until
all other connections
have been made.

Batteries
See the FAQs section of the Xantrex Web site for information on determining battery bank
requirements.
Consider the following recommendations for battery use.
• Use only the deep discharge types for inverter applications.
• Use the same battery type for all batteries in the bank.
• Use only batteries from the same lot and date in your battery bank. This information is
usually printed on a label located on the battery.
CAUTION: Damage to Equipment
The XW Inverter/Charger is intended to operate with batteries as its source of DC power. Do not
connect DC power sources, such as PV arrays, wind turbines, or micro-hydro turbines, directly to
the XW Inverter/Charger without a battery. Connect DC power sources to a charge controller such
as the XW Solar Charge Controller instead. If DC power sources are connected directly to the
inverter, the DC rating of the inverter can be exceeded and the inverter can be damaged.
Battery Bank Requirements
Step 4: Wiring the Inverter
The DC voltage of the inverter must match the nominal voltage of the system and all
battery-connected devices. If the inverter is a 24-volt inverter, then the battery bank and all
battery-connected devices in the system need to be configured for 24 volts.
Important: The minimum recommended battery bank is 100 Ah. The inverter is designed to
operate with batteries and should not be operated without them. Also, do not allow the battery
bank to become completely discharged. If the voltage of the battery bank falls below 10 volts, the
XW Power System will not operate.
Battery Cable Requirements
WARNING: Fire Hazard
Undersized cables can overheat and melt, creating a fire hazard when subjected to heavy (peak)
loads. Always use a cable of proper size and length, rated for the amperage of the inverter and
batteries.
Important:
not use coarse-stranded wire, as the lack of flexibility may damage battery and inverter terminals.
Battery cable length Runs should be kept as short as practical. Length should not exceed 10 feet (3 m). For best
performance, the positive and negative cables should run alongside each other. Avoid
cable loops.
Battery cable lugs Battery cables must have crimped copper compression lugs or crimped and soldered
copper compression lugs. Soldered connections alone are not acceptable. Lugs must be
rated for use with fine-stranded cable.
Use only fine-stranded copper cables for battery and inverter DC connections. Do
Overcurrent
protection
For safety and compliance with regulations, battery overcurrent protection is required.
Fuses and disconnects must be sized to protect the wiring in the system and are required to
open before the wire reaches its maximum current carrying capability.
975-0239-01-01 2–9
Inverter/Charger Installation
Terminal covers Color-coded snap-on DC terminal covers are provided to prevent accidental contact with
the terminals. Terminal covers are required for all installations, even if a XW Conduit Box
is used. It is also recommended that the shank of the ring terminals (cable lugs) be covered
with heat shrink or some other form of insulation.

Installing the Battery Temperature Sensor
The Battery Temperature Sensor (BTS) port is for connecting to the Battery Temperature
Sensor, which regulates battery charging based on battery temperature. Installing a sensor
extends battery life by preventing overcharging in warm temperatures and undercharging
in cold temperatures. This port is also considered part of the DC interface (see Figure 2-9).
To install the Battery Temperature Sensor:
1. Pass the end of the Battery Temperature Sensor cable through a conduit hole and insert
the Battery Temperature Sensor plug into the Battery Temperature Sensor port.
2. Route the cable to the battery enclosure and connect the ring terminal on the Battery
Temperature Sensor directly to a battery terminal (recommended), or use the adhesive
backing on the sensor back to attach the sensor to any side of the battery to be
monitored.
If using the adhesive backing, install the Battery Temperature Sensor on the side of the
battery below the electrolyte level. It is best to place the sensor between batteries and
place the batteries in an insulated box to reduce the influence of the ambient
temperature outside the battery enclosure.

CAUTION:
Damage to the Inverter
The inverter’s AC output must never be wired to the utility or generator output. This will cause
severe damage to the inverter which is not covered under warranty.
Do not use a GFCI equipped AC source to power either the grid or generator inputs. The
AC input filters on the XW may cause nuisance tripping of ground fault protected outputs.
AC Connections and Communication Ports
AC Connections The AC terminal block includes three terminals each (L1, L2 and Neutral) for AC Grid
input, AC Generator input, and AC Load connections. The neutrals are connected to each
other, requiring only one neutral connection when installed with an XW Power
Distribution Panel. Without the XW Power Distribution Panel, additional neutral
connections may be required at the input sources.
Communication
Ports
Four communications ports and one AUX Port are located on the bottom of the inverter
and support the following features.
• The two AC sync ports are used for connecting multiple inverters in parallel.
• The two Xanbus ports are used for network connections between inverters, charge
controllers, and accessories.
• The AUX port provides 12 Vdc/250 mA output to control a relay, fan, indicator light
or other device. The auxiliary output can be configured (using a XW System Control
Panel) to trigger in response to low- or high-battery voltage or high- or low-battery
temperature. The auxiliary output can also be triggered manually using a XW System
Control Panel.

AC Wiring to the Inverter AC Distribution Panel
An inverter AC distribution panel (also known as a sub-panel or inverter load panel) and
AC conduit must be installed before AC wiring is connected to the inverter.
Install the inverter AC distribution panel and conduit as follows:
1. Determine the location for the inverter AC distribution panel and install it according to
the manufacturer’s directions.
2. Install an AC conduit between the XW Power Distribution Panel and the inverter AC
distribution panel.
3. Determine which circuits the inverter will power and install the appropriate circuit
breakers into the inverter panel.
4. For On-Grid systems:
a) Disconnect all power to the main utility panel.
b) Determine which circuits will be backed by the inverter(s) and remove their wires
from the main panel.
c) Reroute these wires to the new inverter subpanel.
5. Remove unused breakers from utility panel. It is now safe to re-energize the main
utility panel.
6. Install a 60-amp maximum (disconnect) main circuit breaker in the inverter panel.
This will later be wired to the inverter’s output.
Step 4: Wiring the Inverter
WARNING: Shock Hazard
Before making any electrical connections, ensure both the AC and DC disconnect devices are in the
OPEN (disconnect) position.
CAUTION: Equipment Damage
Verify that only one neutral/ground bond exists in the system. Having more than one neutral to
ground bond in a system violates local electrical codes, may create a shock or fire hazard, and may
cause some sensitive equipment to malfunction.
CAUTION: Damage to the Inverter
The inverter’s AC output must never be wired to the utility or generator output. This will cause
severe damage to the inverter which is not covered under warranty.

Basic Functional Test - Single Inverter
The following steps will complete a basic functional test of the XW Inverter/Charger. If
any test fails, please refer to the Troubleshooting section in the XW Inverter/Charger
Operation Guide for assistance.
Confirm All Connections
Once the AC and DC wiring have been installed and connected, take a moment to go back
over all connections and make sure they are secure and have been installed correctly.
Applying DC Power to the Inverter
CAUTION: Reverse Polarity Damage
Before making the final DC connection or closing the DC breaker or disconnect, check cable
polarity at both the battery and the inverter/charger. Positive (+) must be connected to positive (+).
Negative (–) must be connected to negative (–).
Reverse polarity damage is not covered by warranty.
Basic Functional Test - Single Inverter
To apply DC power to the inverter:
1. Before applying DC power to the inverter, measure the voltage and polarity of the
cables (measure at the battery side of the disconnect or breaker).
Important:
Voltage should be between 40 to 60 volts for a 48-volt
system, and 20 to 30 volts for a 24-volt system. If the DC voltage is low,
the battery bank needs to be charged externally. Charge the battery bank
and restart the functional test.
2. Apply battery (DC) power to the inverter by closing the battery bank DC disconnect.
The inverter will power up, the display will illuminate, but the inverter will remain in
the Standby Mode (as shown in Figure 2-19).

3. Monitor the INVERT (Green kW) LED to confirm which mode the inverter is in:
• LED Off – Invert Mode is disabled. The inverter/Charger is not powering the AC
loads. However, if good AC is present, it is passed through to the loads.
• One blink/sec – The inverter/charger is in the Search Mode and is looking for an
AC load greater than the Search Watts setting (default = 25 watts). The Display
shows Sch (Search) when this mode has been enabled.
• LED On – The inverter/charger is on. The inverter is operating and is able to
provide power to the AC loads. This is the default mode on initial powerup once
the unit is taken out of Standby Mode.
If the inverter is not operating or the INVERT LED (kW) does not illuminate, check all
connections. Check the inverter’s DC voltage on the positive (+) and negative (–)
terminals. Check the Fault LED. If the fault LED is illuminated, check for a fault code on
the information panel. Correct the reported fault if possible and clear the fault. If the DC
voltage is low, the battery bank needs to be charged externally. Charge the battery bank

Basic Functional Test - Multiple Inverters
The following steps will complete a basic functional test of multiple XW Inverter/
Chargers. If any test fails, please refer to the Troubleshooting section in the XW Inverter/
Charger Operation Guide for assistance.
To perform a functional test on multiple inverters:
1. Check/verify all wiring and cable connections.
2. Measure DC voltage at the DC terminals on the inverter and confirm its within range
and has correct polarity. The acceptable range is >20 Vdc for 24 V system or >40 Vdc
for 48-V Systems.
3. Switch INV1 DISCONNECT to ON position.
4. Check inverter display for startup self-test during which all LED's will flash
momentarily. Once self-test is complete, inverter will display "Stb". (The Fault/
Warning LED may flash for a few seconds but eventually will turn off. If Fault/
Warning LED persists, check to ensure battery temperature sensor is connected. Also,
if the inverter has been pre-configured, it may go straight into normal operating
mode.)

a) Go to the inverter’s Advanced Settings menu by pressing Down arrow + Enter
from System Status screen and then simultaneously pressing Enter + Up arrow +
Down arrow.
b) Select Multi Unit Config menu.
c) Change Dev Number from “00” to “01”. The inverter will now appear as
XW6048-01 in the device list.
d) Press Exit to go back to the System Status screen.
6. Switch INV2 DISCONNECT to ON position.
7. Check inverter display for startup self-test during which all LED's will flash
momentarily. Once self-test is complete, inverter will display "Stb". (If the inverter has
been pre-configured, it may go straight into normal operating mode or display F66
warning.)
Basic Functional Test - Multiple Inverters
8. Using the XW System Control Panel, set Second (Slave) Inverter Device Number and
Inverter Mode.
a) Select new inverter XW6048-00 in the device list.
b) Go to the inverter’s Advanced Settings>Multi-Unit Config menu.
c) Change Dev Number from “00” to “02” (or the next number that hasn’t been

c) Set Max Chg Rate to 10%.
d) Press Exit until you see the System Status screen.
19. Switch AC Input breakers ON. Note - all inverters in the system must be connected to
the same AC Input source before they will qualify the source.
20. Confirm both inverters start charging. Note -- With the Max Chg Rate set to 10% the
maximum charge rate is limited to 10 A on each inverter. Depending on the battery
bank’s state-of-charge, the output from one or more inverters may quickly drop to
zero. This is considered normal operation.
21. Check for faults. If fault condition(s) exist, correct and restart Functional Test.
If the Inverters pass the Functional Test, proceed to Commissioning procedure as defined
in XW Inverter/Charger Operation Guide.

Xanbus Network
3
Installation
Chapter 3, “Xanbus Network Installation” provides detailed information for
planning and installing the components necessary for network
communication on a Xanbus system.
For this Topic See....
“Xanbus-enabled Devices” page 3–2
“The Xanbus System” page 3–2
“Installing the Network” page 3–7
Xanbus Network Installation
Xanbus-enabled Devices
The Xanbus™-enabled designation means that the product works on a Xanbus network.
Xanbus-enabled products are:
• Easy to use. The Xanbus network simplifies operation and automates routine tasks.
• Reliable. Software control eliminates errors due to analog signalling.
• Accurate. Digital information is less susceptible to interference and line loss.
The Xanbus System
What is a network? A network is a collection of devices that perform individual functions, but also
communicate and interact with the other devices. The network capability of the XW
Power System provides a robust, integrated product solution that simplifies and automates
the installation, configuration, control, monitoring, and integration of devices that deliver
and distribute AC or DC power.
Network
components
Each device is integrated into the network using cables, network connectors, and
terminators. An example of a network-managed power system is shown in Figure 3-1.
Figure 3-1
Network
configurations
3–2 975-0239-01-01
Network-Managed Power System
The network can be installed in one of two configurations: as a multi-drop backbone (see
Figure 3-5) or as a daisy chain (see Figure 3-6).
Network Components
A Xanbus network consists of the following components:
• Xanbus-enabled devices—these include the XW System Control Panel, the XW
• Xanbus power supply—the network must have at least one device with a power supply
Important: See the specifications for each Xanbus device to determine how much power each
device consumes or supplies.
The Xanbus System
Inverter/Charger, XW Automatic Generator Start, and XW Charge Controller. The
maximum number of Xanbus devices connected to a single Xanbus network should
not exceed eight devices.
to run the network. The total network current supplied by all the power-sourcing
devices must be greater than or equal to the total current drawn by the power
consuming devices. The power supply must be capable of providing 15 Vdc/200 mA
to each device. The XW Inverter/Charger can provide sufficient network power.
For example, in a system with an inverter/charger, a XW System Control Panel and an
Automatic Generator Start, the inverter/charger is a power-sourcing device capable of
providing 800 mA at 15 Vdc while the two other devices each consume a maximum of
200 mA for a total maximum consumption of 400 mA. In this example, the network is
properly configured from a power perspective because the power source is capable of
providing more current than is needed: 800 mA > 400 mA.
• Xanbus cables—each Xanbus-enabled device is connected by a Category 5 (CAT 5 or
CAT 5e) cable, a standard cable available from Xantrex or any computer supply store.
The cable consists of eight conductors in four twisted pairs with an RJ45 modular
connector wired to the T568A standard.
CAUTION: Equipment Damage
Do not use crossover cable.
Table 3-1 contains the arrangements of wire colors to pin numbers for the T568A
standard.

• Network terminators (Figure 3-3)—the Xanbus network must be properly terminated
at each end with male or female network terminators to ensure the communication
signal quality on the network. 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. The XW Series and other
Xanbus-enabled devices ship with one male terminator already installed. Depending
on your network layout, this terminator may need to be removed and inserted into
another device elsewhere in the network.
Male network terminator

Network Terminators
Female network terminator
• Network connectors—The three-way connector houses three RJ45 inputs that provide
a device connection point on a multi-drop backbone layout (see “Multi-Drop
Backbone Layout” on page 3–5). All three inputs are wired identically and can accept
either Xanbus cables or terminators. One input is available for connecting to a
Xanbus-enabled device. The remaining inputs are reserved for connection to other
network connectors, a Xanbus cable terminated with a female terminator, or a male
terminator.
The network connector is mounted to a bulkhead or a wall, as shown in Figure 3-4.

Xanbus Network Components and Part Numbers
Xanbus-enabled devices can be connected in one of two Xanbus network layouts:
multi-drop backbone or daisy chain. Each network layout has advantages and
disadvantages, depending on the application and/or environment. It is up to the installer or
system designer to decide which layout is best for the installation.
Important:
supported by Xantrex.
Multi-Drop Backbone Layout
In a multi-drop backbone layout, each Xanbus-enabled device on the network is connected
by a drop cable to the network bus or backbone with a network connector, as shown in
Figure 3-5.
Terminators are required at both ends of the multi-drop backbone cable, as shown in
Figure 3-5. Therefore, the Xanbus-enabled devices do not require their own termination.
With only one terminator, the signal quality is degraded and performance on the network is
reduced. Permanent configuration with only one terminator is not supported by Xantrex.
If cables are placed at the end of the network, female terminators are required. Otherwise,
male terminators can be inserted directly into the open jack of each network connector at
the end of the network.
Advantages In this layout, Xanbus-enabled devices can be removed or replaced while
still keeping the network operating.
Disadvantage The main disadvantage of this layout is the cost of the network
connectors (a daisy chain layout uses no network connectors). Each device in this layout
requires its own network connector.
Do not mix the two types of network layouts. Mixed configurations are not

Figure 3-5
Multi-Drop Backbone Layout
Daisy Chain Layout
In a daisy chain layout, each device on the network is linked with separate lengths of
Xanbus cable, as shown in Figure 3-6. This layout does not require network connectors.
As in the multi-drop backbone layout, two terminators are required to ensure the
communication signal quality on the network. The Xanbus-enabled devices at each end of
the chain must have a male terminator inserted into their open network ports.
Advantage The advantage of this layout is that it is less expensive to install because
network connectors are not required.
Disadvantage The disadvantage of the daisy chain layout is that Xanbus-enabled
devices cannot be removed from the network without interrupting the network. To make
the network function after removing a device, you must connect the Xanbus-enabled
devices on either side of the missing device to each other or replace the device.

Guidelines for Routing the Xanbus Cables
WARNING: Shock hazard
:
Do not route the Xanbus cables in the same conduit or panel as the AC and DC power cabling.
To ensure maximum performance of your network, follow these guidelines when routing
the Xanbus cables.
• Route the cables away from sharp edges that might damage the insulation. Avoid sharp
bends in the cable—no less than a 4-inch (100 mm) radius.
• Allow at least 2 ¼ inches (57 mm) of space behind the wall to accommodate the depth
of the unit and allow room for the cables to bend.
• Allow for some slack in the cable tension.
• Keep the alignment of wire pairs inside the sheath as straight as possible.
• Allow separation between data and power cables (data cables should only cross a
power cable at right angles).
• Do not staple the cable with metal cable staples. Use appropriate hardware fasteners to
avoid damage to the cable.
• Support horizontal cables using J hooks or cable trays.

XW Solar Charge Controller Installation
Installing the Charge Controller
This chapter describes installing the XW Solar Charge Controller with the XW Power
System, including the power distribution panel. For stand-alone installation, see the XW
Solar Charge Controller Owner’s Guide.
PV Array Requirements
Each Charge Controller must be connected to its own PV array. For optimum
performance, each individual array must be composed of the same type of solar panel,
with the same V
Important: The following information provides only general guidelines. The installation and
rated performance of your PV array is subject to inspection and approval by the authority having
jurisdiction.
Array Size
For PV array sizing guidelines, use the XW Solar Charge Controller PV array sizing tool
accessible from www.xantrex.com/support.
Although the Solar Charge Controller can harvest a maximum of 3500 W, the PV array
size can be as large as 6720 W (based on 48 A × 140 Vdc = W).

MPPT Voltage Range
The XW Solar Charge Controller maximum power point tracking algorithm maximizes the
output power of PV arrays as long as the operating voltage is within the MPPT operational
window. Ensure that the PV array used in the system operates within the MPPT
operational window.
Effects of array voltages outside of the MPPT operational window are shown in Table 4-1.

Grounding
The XW Solar Charge Controller is designed to work only with negative-grounded
electrical systems. Grounding for both PV and battery circuits is provided inside the
wiring compartment. Each ground connection can accommodate up to #6 AWG wire size.
A fuse rated at 1 A, 600 V (accessible from inside the wiring compartment) grounds the
negative conductor of the PV array and provides PV ground-fault protection (PV-GFP).
Replace with Littelfuse KLKD 1 or equivalent.
Important:

Seriess, remove the PV-GFP fuse from each unit except one.
Only one Charge Controller is to have the PV-GFP fuse installed in
WARNING: Shock Hazard
Do not connect the battery negative to ground. NEC requirements specify that the battery
negative ground must be done only through the 1A PV-GFP fuse. Bonding the battery
negative to ground disables PV ground-fault protection. The battery compartment must
only be grounded if it is metal.
WARNING: Fire Hazard
Ensure there is no other ground connection in the DC
wiring or the PVGFP will be defeated and will not protect
the array from ground fault conditions.

WARNING: Equipment damage
Do not connect an array capable of delivering over 60 A Isc to the XW Solar Charge Controller.
Wires larger than #6 AWG can be used only to reduce power loss in the wiring.
To use a larger size wire, use a splicer block (terminal block) approved and rated for this
application. This allows the larger cable size from the batteries to be “spliced” to the #6
AWG wire connected to the XW Solar Charge Controller. The splicer block must be
installed outside of the XW Solar Charge Controller wiring compartment.

XW Solar Charge Controller Installation
Connecting the XW Solar Charge Controller to the Distribution Panel
WARNING: Shock Hazard
Whenever a PV array is exposed to light, a shock hazard exists at the output wires or exposed
terminals. To reduce the risk of shock during installation, cover the array with an opaque (dark)
material before making the connections. PV arrays generate voltage whenever light strikes the
surface of the array. Before connecting the XW Solar Charge Controller, cover the array to prevent
any current from being generated.
WARNING: Shock Hazard
Do not connect the battery negative to ground. Bonding the battery negative to ground disables PV
ground-fault protection.
To connect the XW Solar Charge Controller:
1. Connect the PV array’s positive (+) output to the PV array disconnect.
2. Route another (+) cable from the other end of the PV disconnect to the terminal
marked
PV + in the XW Solar Charge Controller.
3. Connect the PV array’s negative (–) output to the terminal marked
PV – in the XW
Solar Charge Controller.
4. Connect a positive (+) cable from the terminal marked
BAT + to the battery disconnect.
5. Connect a second positive (+) cable to the other side of the battery disconnect and
connect to the positive (+) battery terminal.
6. Connect the negative (–) battery cable to the terminal marked
BAT – in the XW Solar
Charge Controller.
7. Torque the Charge Controller terminals as follows.
• 15 inch-pounds (1.7 Nm) for #14–10 AWG wire

XW Solar Charge Controller Installation
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 Solar Charge Controller before powering up for the
first time.
Configuration Screens
When power is first applied to the XW Solar Charge Controller, several configuration
screens prompt you to enter the following information:
• A “DC out” (battery) connection, which enables the XW Solar Charge Controller 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 Solar Charge
Controller.
The XW Solar Charge Controller automatically detects battery voltages of 12 V, 24 V
and 48 V. If your nominal system voltage is 36 V or 60 V, enter the correct system
voltage on this screen.
• 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 Inverter/Charger Operation
Guide.
Commissioning units using an SCP involves three separate procedures:
1. Setting the Device Numbers for all XW Solar Charge Controllers.
2. Configuring Connections and Charger Settings for the first XW Solar Charge
Controller.
3. Copying settings from the first unit to the other XW Solar Charge Controller.
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 Solar Charge Controllers at the same time. When the XW Solar Charge
Controllers 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.

Commissioning
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).
4. On the MPPT Setup menu, ensure the Advanced Settings item is displayed. If
Advanced Settings are not displayed (and Basic Settings appears as the last item on the
menu), press the up arrow, down arrow and Exit keys together. (See “Advanced menu”
on page B-7 of the XW Inverter/Charger Operation Guide.)
5. Select Advanced Settings, then select the Multi Unit Config menu. After entering the
Multi Unit Config menu, the LCD backlight on the XW Solar Charge Controller to be
configured will flash.
6. On the Multi Unit Config menu, select Dev Number and set it to a number other than
00.
The device number can be set to any number between 01 and 31. For the first XW
Solar Charge Controller, 01 is recommended. If you have two charge controllers,
simply set them to 01 and 02.
7. Press Exit until the Select Device menu is displayed.
The XW Solar Charge Controller now appears as MPPT60 01 on the menu.
8. Repeat steps 3 through 7 for the next XW Solar Charge Controller.
When you have set the device number for all XW Solar Charge Controllers, you can
configure Connections and Charger Settings for the first XW Solar Charge Controller.
To configure Connections and Charger Settings for the first XW Solar Charge
Controller:
1. On the Select Device Menu, select “MPPT60 01.”
2. Navigate to the Multi Unit Config menu and select Connections.
On the Connections menu, you can configure PV In (PV input) and DC Conn (DC
output, or the battery bank). If the system has only one battery bank, leave DC Conn at
the default setting. The PV In setting allows you to differentiate which array is going
to which XW Solar Charge Controller. This setting is used for status reporting only,
not for any internal controls. Setting PV In to a non-default value is optional.
3. Press Exit twice to leave the Connections menu and Multi Unit Config menu.
4. From the Advanced Settings menu, select Charger Settings.
5. Set the Battery Type, Battery Capacity, and any other charger settings required for
your system.
While in the Charger menu, ensure that the Nominal Battery Voltage is set correctly (it
is shown as Batt Voltage and appears as the last item on the menu). If you select
“Custom” for your Battery Type, you can further configure the Bulk, Absorption,
Float and other settings for the charge cycle.
The first charge controller should now be configured properly for your system.
If multiple charge controllers are installed, you can now copy the first unit’s
configuration over to other units.
To copy the XW Solar Charge Controller setup to another unit:
1. On the SCP, press Exit to leave the Advanced Settings menu and view the Select
Device menu.
2. On the Select Device Menu, select the next XW Solar Charge Controller for
configuration.

3. On the Advanced Settings menu, select Copy From, then select the XW Solar Charge
Controller you want to copy from. You should select the unit with the device number
that matches the first unit you configured.
4. Press Enter.
The settings are automatically copied from the selected unit.
Note: The Copy From command will not give you any indication that it has completed
its task. However, you can quickly check for yourself that the charger settings you have
chosen have been copied properly by viewing some of the settings you originally
configured.
5. Uncover the PV array and/or apply power with the disconnect or selector switch.
The XW Solar Charge Controller starts up in sleep mode and waits for a short period to
determine that the input voltage is greater than the output voltage. After the input voltage
exceeds the output voltage by the required margin for 10 seconds, the unit begins
operating.
