Safety

Explosive gas precautions

WARNING: Explosion hazard

1. Working in the vicinity of batteries may be dangerous. Batteries can generate
explosive gases during normal operation. Therefore, you must read this guide
and follow the instructions exactly before installing or using your XW
Inverter/Charger.

2. To reduce the risk of battery explosion, follow these instructions and those
published by the battery manufacturer and the manufacturer of the equipment
in which the battery is installed.

Precautions When Working With Batteries

WARNING: Explosion or fire hazard

1. Follow all instructions published by the battery manufacturer and the
manufacturer of the equipment in which the battery is installed.

2. Make sure the area around the battery is well ventilated.

3. Never smoke or allow a spark or flame near the engine or batteries.

4. Use caution to reduce the risk of dropping a metal tool on the battery. It could
spark or short circuit the battery or other electrical parts and could cause an
explosion.

5. Remove all metal items, like rings, bracelets, and watches when working with
batteries. Batteries can produce a short circuit current high enough to weld
metal to skin, causing a severe burn.

6. Have someone within range of your voice or close enough to come to your aid
when you work near a battery.

7. Have plenty of fresh water and soap nearby in case battery acid contacts skin,
clothing, or eyes.

8. Wear complete eye protection and clothing protection. Avoid touching your
eyes while working near batteries.

9. If battery acid contacts skin or clothing, wash immediately with soap and
water. If acid enters your eye, immediately flood it with running cold water
for at least twenty minutes and get medical attention immediately.

• Integrated transfer switch

• Temperature-controlled, variable-speed internal cooling fan. The fan turns on
when the internal temperature reaches 45 °C and reaches maximum speed at
70 °C. The fan turns off when the internal temperature falls to 40 °C.

• Housing design promotes vertical air flow through the inverter. This natural
“chimney effect” helps provide convection cooling at lower power levels, and
reduces fan run time.

• Designed for reliability and field serviceability.

The XW Inverter/Charger uses Xanbus™, a network communications protocol
developed by Xantrex, to communicate its settings and activity to other Xanbus­enabled devices. You can configure and monitor the XW Inverter/Charger and
every Xanbus-enabled device in the system using an XW System Control Panel
(part number 865-1050).

Basic Operation

Basic Operation

The XW Series Inverter/Charger is a modular “building block” sine-wave
inverter/charger that can be used for both residential and commercial stand-alone,
grid-backup, and grid-tie applications with battery ener gy storage. The XW
Inverter/Charger is a self-contained DC to AC inverter, battery charger and
integrated AC transfer switch. Up to three inverters can be installed together in a
120/240 V split phase configuration.

Multi-unit operation Inverting For multiple XW Inverter/Chargers, the master inverter/charger

broadcasts pulses on the Xanbus network to synchronize and arbitrate operation
between the other paralleled units. This coordination of multi-unit operation
results in reduced tare loss and improved efficiency—other paralleled units stay in
low-power mode until they are needed.

For paralleled XW Inverter/Chargers, only one inverter/charger operates, and
additional devices come on-line only when the load exceeds approximately 60 per
cent of the rated output of the master inverter/charger. In a three-unit system,
additional slave units come on sequentially if the load on the master does not drop
below 60 per cent about 3 to 5 seconds after a slave unit turns on to assist the
master. When the load drops below 20 per cent of the master’s rated output, the
slave units turn off in reverse order; that is, the last slave unit to turn on will be
first to turn off.

The current sharing imbalance for a single inverter/charger does not exceed 10 per
cent of the rated maximum nominal output power. All non-utilized inverter/
chargers are off-line when no load is present.

Parallel charging When multiple XW Inverter/Chargers are charging in a
system, they synchronize charging stages to ensure efficient charging of the
battery bank. All units transition from bulk to absorption when a single unit does.
In absorption, all units must complete the absorption stage before transitioning to
the next stage. Note that units do not load share when charging. Each unit charges
batteries based on the Max Charge Rate setting and active internal (temperature­based) deratings.

If equalize is enabled on one or more devices capable of equalization charging
(such as XW Inverter/Chargers or XW Series Solar Charge Controllers), only
those devices initiate and perform a equalize cycle after absorption. Other devices
will float (if three-stage charging is selected) or transition to AC pass-through (if
two-stage charging is selected).

When one or more XW Series Solar Charge Controllers are installed and
operating in the system, the XW Inverter/Chargers synchronize charging stage
(bulk, absorption, or float) with the charge controllers. In a similar fashion to the
XW Inverter/Charger charge behavior , charge controllers also harmonize charging
among themselves.

AC Transfer XW Inverter/Chargers monitor each other using a peer-to-peer
monitoring technique to determine the quality of AC input. If AC input is deemed
bad by any of the paralleled units, no transfer to AC occurs and the units may

975-0240-01-01 1–3

Introduction

continually flash the AC LED on their respective information panels. If the
system was in pass-through and AC fails on any unit, all units transfer to invert
simultaneously.

Faults When an XW Inverter/Charger in a multi-unit system has a fault, only
the affected device shuts down, except in the following cases:

• When a master unit has an invert mode fault that causes it to stop inverting, a
system wide fault occurs. Invert mode faults on a slave unit shut down only
the affected slave unit.

• Battery-related faults such as battery over-temperature or over-voltage.

Other modes of operation XW inverter/chargers operate independently when
in grid support mode (including sell mode), load shave, generator support and
charger block modes. This allows units to be configured to perform a multiple of
functions independently and allowing greater flexibility in operating the system.

Auxiliary output Each XW Inverter/Charger has one programmable auxiliary output that is able to

run a small 12 V fan or operate an external relay to perform other functions, such
as to remotely start a generator (if the Xanbus-enabled XW-AGS is not used), to
disconnect external non-critical loads, or to turn on a diversion load for battery
voltage regulation.

Transfer relay The built-in transfer relay is rated for 60 amps. When an external AC source is

detected on either of its two AC inputs, the switch transfers loads from the XW
Inverter/Charger to the external power source, and then activates the battery
charger to re-charge the battery bank.

AC1 and AC2 relay The XW Inverter/Charger design does not allow the AC1 and AC2 inputs to feed

into each other. The relays controlling AC1 and AC2 input can never close
simultaneously. This design prevents generator input from feeding out to the
utility grid.

Surge Performance

Unlike many other inverters, the XW Inverter/Charger prevents voltage from
sagging dramatically during surge conditions. The XW Inverter/Charger handles
surges of over twice the inverter’s rated output with only a minimal drop in output
voltage.

1–4 975-0240-01-01

Islanding Protection

Islanding protection is an essential safety feature that ensures no person working
on the utility grid is harmed by a distributed energy source, such an XW Inverter/
Charger. Islanding protection also prevents loads connected to the inverter from
being damaged by fluctuating utility grid input. Default software settings are
programmed into each XW Inverter/Charger at the factory to ensure it does not
“island” according to applicable safety regulations (such as IEEE 1547 and UL

1741).
As well, the XW Inverter/Charger uses a proprietary positive feedback controller

that has minimal effect on total harmonic distortion, and is guaranteed to detect
islanding conditions for all power levels, as governed by IEEE and UL standards.

In some instances it may be desirable from both a utility and customer point of
view to adjust default anti-islanding settings. For example, the XW Inverter/
Charger may experience “nuisance trips” if the grid is weak and the voltage falls
outside the allowable range specified in the regulations. It may be difficult for a
utility to upgrade the grid to eliminate this problem. With permission from the
utility, the factory settings may be changed to allow the XW Inverter/Charger to
operate over a wider grid voltage range.

These settings should only be changed by qualified service personnel, using a
special software application provided by Xantrex. Changing any values may
compromise compliance with safety regulations. Do not do so without first
consulting with the utility and agreeing on acceptable settings.

While selling power, the XW Inverter/Charger continuously monitors utility grid
voltage and frequency. If the grid voltage and frequency move beyond the XW
Inverter/Charger default ranges
the XW Inverter/Charger stops selling power to AC1 and disconnects from the
utility grid for five minutes (Five minutes is the minimum reconnect time, and is
not adjustable.) If the utility grid voltage and frequency have returned to their
nominal values when the reconnect time has expired, the XW Inverter/Charger
begins selling power again.

The Fault light on the XW Inverter/Charger information panel indicates that a
utility fault has occurred. No fault code appears on the three-character display
because the fault is with the utility grid, not the XW Inverter/Charger.

Basic Operation

—during a power surge or outage, for example—

The XW System Control Panel indicates a utility fault with the Fault light and a
fault message on its screen (faults F23 to F40 are utility faults—see Table 4-5 on
page 4–18). The fault cannot be manually cleared. Utility faults clear
automatically when the utility grid voltage and frequency return to their nominal
values.

Equalizing Batteries

Button Pressing the Equalize button (indicated by the symbol) for five seconds turns

battery equalization on and off. After this button is pressed, the XW Inverter/
Charger begins the equalization charge after the next charge cycle is complete.
Equalization functions only if AC is present and qualified and the charger is
enabled. Otherwise the inverter/charger generates a “cannot equalize” fault
(W96).

CAUTION: Battery damage

Equalization may damage your battery. Consult your battery supplier for details on
equalize charging for the battery type in your system.

Important:

(such as a system including multiple XW Inverter/Chargers and Solar Charge Controllers),
there is no system-wide equalization command for all devices. To equalize with multiple
devices, each would have to be enabled individually. Alternatively, equalization can be
performed using only one device. During the equalization process, one device applies the
equalization charge while the other devices continue to operate in synchronized charge
mode, typically in float (three-stage charging) or no-float (two-stage charging).

In a system where more than one device is capable of equalizing batteries

Monitoring Operation with the Inverter Information Panel

Turning the XW Inverter/Charger On and Off

On/Off control When the XW Inverter/Charger is operating, pressing and holding the On/Off

button () for five seconds turns the unit off. Pressing the On/Off button
momentarily returns the unit to its previous operating state.

When the XW Inverter/Charger is being turned off, the other Inverter Information
Panel buttons stop working. The shutdown process cannot be cancelled. The XW
Inverter/Charger can only be turned back on once the display is blank.

Standby mode In Standby mode, the XW Inverter/Char ger stops charging, inverting, and passing

through AC input. However, the unit remains powered up and present on the
Xanbus network.

To put the XW Inverter/Charger into Standby mode, press and hold the On/Off
button and the Equalize button simultaneously for about five seconds. The display
shows “Stb.” To return the XW Inverter/Charger to operating mode, press the On/
Off button momentarily.

Pressing the On/Off button momentarily while the XW Inverter/Charger is
operating clears active faults and warnings.

Single-unit
installations

Multiple-unit
installations

In a single-unit installation, when the XW Inverter/Charger is turned off using the
On/Off button, Xanbus network power is lost. When Xanbus network power is
lost, network-connected accessories such as the Automatic Generator Start (XW­AGS) and XW System Control Panel lose power and stop operating. XW Charge
Controllers continue to operate and communicate between each other if Xanbus
network power is removed.

If the On/Off power button is pressed and held on a master XW Inverter/Charger
(see “Inverter Mode” on the “Multi-Unit Config Menu” on page 3–23) and an
XW-AGS is installed in the system, the unit stop s inverting/char ging immediately
and turns off completely in 120 seconds. During this time, the display shows
“OFF.” This interval allows the XW-AGS to stop the generator after a “cool
down” period. During the 120-second shutdown time all network communication
is blocked and the unit sends a shutdown command to all other devices in the
system. As well, the Inverter Information Panel buttons stop working and the
shutdown process cannot be cancelled. The XW Inverter/Charger can only be
turned back on once the display is blank.

In a multiple-unit installation, when a Slave XW Inverter/Charger is turned off,
other XW Inverter/Chargers continue to supply Xanbus network power and the
XW-AGS and XW System Control Panel continue operating.

The Standby button has two functions, depending on how it is pressed. Th e
Standby button can disable inverting and charging for all XW Inverter/Chargers in
the system, or, when pressed simultaneously with the Exit button, put the entire
system into Standby mode.

Pressing the Standby button produces the same result as disabling “Invert” and
“AC Charge” from the System Settings menu on the XW System Control Panel.
Pressing the Standby button momentarily affects only XW Inverter/Chargers; it
does not affect Charge Controller operation. After disabling inverting and
charging with the Standby button, the system continues to pass AC input through
to the loads, and “– – –” is displayed on the Inverter Information Panel.

Pressing the Exit and Standby buttons at the same time puts the entire XW power
system (including Charge Controllers) into Standby mode. In Standby mode, the
XW Inverter/Chargers stop passing AC input through to the loads, and “Stb” is
displayed on Inverter Information Panel.

After the keypress command to enter Standby mode, the XW-AGS (if installed)
shuts down the generator (if it is running) after a cool-down cycle.

by supplying additional power to the critical loads.
The XW Inverter/Charger supports the generator (or other power source connected to the AC2
input) when the AC load current drawn from AC2 exceeds 80 per cent of the AC2 breaker
setting or GenSup Amps setting for 1 to 2 seconds.
The XW Inverter/Charger uses stored DC capacity to load share with the generator until the total
AC load current (generator plus inverter output) drops by 2 amps plus 10 per cent of the GenSup
Amps setting for 6 seconds.
For example if GenSup Amps is set to 10 amps, the inverter starts to support when the load
exceeds 10 amps for 2 seconds and stops when it drops more than 3 amps below the GenSup
Amps setting, or 7 amps (2 amps plus 10 per cent of 10 amps = 3 amps).
The system can enter this state if the battery voltage is above the Low Batt Cut Out setting and
Gen Support is enabled. See “Generator Support Settings” on page 3–21.

supplying additional power to the critical loads.
The XW Inverter/Charger supports the utility grid by limiting the power drawn from the utility
to less than 10 per cent of the load demand. This mode is desirable for using excess energy from
auxiliary DC sources like PV, while still maintaining a charged battery bank. No power is sold to
the utility in this mode.
The XW Inverter/Charger uses stored DC capacity to support the grid until the total AC load
current (grid plus inverter output) drops by 2 amps plus 10 per cent of the Load Shave Amps
setting for 6 seconds.
The XW Inverter/Charger enters this state only when the Grid Support is set to “On” and battery
voltage is above the Grid Supp Volts setting. See “Grid Support Settings” on page 3–17.

Load Shaving There is AC input from the utility, and the XW Inverter/Charger is supporting the utility grid

when the current required to power the loads rises above the Load Shave Amps setting between
the Load Shave Start and Load Shave Stop times set on the Grid Support menu.
Many utilities impose a surcharge on their customers based on the peak load used by a facility.
When load shaving, the XW Inverter/Charger uses stored DC capacity to reduce the peak load
on the utility grid and keep current draw from the grid equal to or under the Load Shave Amps
setting. The XW Inverter/Charger enters this state only when Grid Support is enabled, the Load
Shave time window is valid and the load draw exceeds the Load Shave Amps setting. See “Grid
Support Settings” on page 3–17.

This setting controls when the inverter turns off due to a low battery voltage
condition. The inverter will turn off only after this level has been reached
for the period of time set by the LCBO Delay. This setting is not
temperature compensated.

LBCO Delay controls how long the inverter is allowed to operate at or
below the Low Battery Cut Out level before turning off due to a low battery
voltage condition. The inverter will turn off only after the Low Batt Cut Out
level has been reached for this uninterrupted period of time.
Once the inverter has shut off, the battery voltage must rise 4 volts above
the Low Batt Cut Out setting for inverter operation to resume.

High Batt Cut Out sets the maximum battery voltage at which the inverter
will operate. If the battery voltage exceeds this limit for more than 1
minute, the inverter displays a fault message (F49) and shuts down. The
inverter will not support AC loads when in this condition. If a qualified AC
source is present, the unit passes AC through to the loads. The inverter
automatically restarts when the voltage drops to 3 volts (24-volt system) or
6 volts (48-volt system) below the High Batt Cut Out setting. If battery
voltage continues to rise after shutdown, an external charger may still be
charging the batteries. The XW Inverter/Charger cannot control how
external chargers operate.

Search Watts sets the inverter’s search sensitivity when Search mode is
enabled. When a load larger than this setting is present, the inverter turns
on. Enabling Search mode from the Setup Menu (see page 3–2) can
minimize power draw from the battery during periods of low demand from
loads. Also see “Using Search Mode” on page 3–8.

Search Delay sets the time between search pulses. When searching for
loads, the XW Inverter/Charger sends out search pulses to determine if a
load is present. If the XW Inverter/Charger finds a load above the Search
Watts setting, the inverter comes on. XW Inverter/Charger power draw
while in Search mode decreases when Search Delay is increased, but the
inverter’s response time to active loads is reduced.

For default settings, see “Inverter Menu” on page B–3.

Using the Low Battery Cut Out and LBCO Delay Settings

The Low Batt Cut Out setting is the lowest voltage level acceptable for battery use
by the inverter. When the batteries dischar ge to the Low Batt Cut Out setting, and
are held at or below this level for the LBCO Delay time, the inverter output shuts
down and transfers any available AC source (generator or grid) to the charger to

Configuration

Using Search Mode

Why use Search

When to set up
Search mode

bring the battery level back above the Low Batt Cut Out setting. After shutdown,
the inverter does not support any AC loads, and AC loads must be powered by
either a generator or grid power.

If using an automatic generator starting system, it is recommended to set the AGS
voltage trigger setting higher than the XW Inverter/Charger Low Batt Cut Out
voltage. Otherwise, inverter output turns off and then back on when the generator
auto-starts.

If using an automatic generator starting system with the start trigger set to the
same voltage as the LBCO voltage, do not set the LBCO Delay for less than the
amount of time it takes the generator to start and connect. Otherwise, inverter
output turns off and then back on when the generator auto-starts.

While idling in Search mode, the inverter sends out an electrical search pulse that
travels through the AC wiring “looking” for connected loads. The frequency of
the search pulse is set using the Search Delay setting.

After a load larger than the Search Watts setting is detected, the inverter turns on.
Search mode allows you to selectively power only items that draw more than a

certain amount of power, which can result in power savings.
The XW Inverter/Charger has a no-load power draw of about 28 watts. Enabling

Search mode reduces this power draw to less than 8 watts.
The Search mode feature on the inv erte r is only valuable if the inverter can spend

a fair amount of time “sleeping” each day. Therefore, if Search mode is to be
utilized it must be adjusted properly . The initial adjustment should be made so that
the inverter comes on only when needed.

Certain types of loads can cause Search mode not to work as expected. These
types of loads are described on page 4–3 of the Troubleshooting chapter. If these
kinds of loads are in the system, follow the suggestions given to eliminate the
problem. Some televisions with instant-on circuits have a menu or control to
disable it. If clocks are the problem load, consider using battery-powered units.

If the problem loads cannot be eliminated, there are two work-around solutions:

1. Disable Search Mode from the main XW Inverter/Charger Setup menu,
causing the inverter to always remain at full output voltage.

2. Use a search-friendly “companion load” whose only purpose is to be switched
on to “wake up” the inverter to power the load that is unable to bring the
inverter out of Search mode.

Important:

Chargers. The combined current draw of multiple inverter/chargers falsely brings the units
out of Search mode. Search Mode should be disabled on the Setup menu of each XW
Inverter/Charger.

Battery Charger Functions

When AC power is available, the XW Inverter/Charger can operate as a battery
charger . Dif ferent battery types and chemistries require dif ferent charging voltage
levels. Not charging batteries at the required levels can shorten battery life or
possibly damage them. The XW Inverter/Charger is configured at the factory to
work with the battery types recommended for inverter applications. If the default
settings do not work for your specific installation, you can adjust the charge stage
settings (as recommended by the battery manufacturer) on the Custom Battery
Settings menu (see page 3–15). It will be necessary to select the voltage levels
required and to set the voltage limits for the various stages of charging.

Note: This information is provided for guidance only. Variations in battery chemist ry

and site-specific environmental considerations mean that you should consult your system
designer or battery manufacturer for specific recommendations for appropriate battery
voltage and current settings.

Multi-Stage Charging Process

The charging cycle uses a multi-stage charging process to maintain the batteries.
Whenever AC power that is within the range of the inverter’ s settings is present at
the inverter’s input, it passes power through to the connected load and begins
charging the batteries.

Bulk Stage Bulk charge is the first stage in the charging process and provides the batteries

with a controlled, constant current. Once the battery voltage rises to the bulk
voltage threshold, the charger switches to the Absorption stage.

975-0240-01-01 3–11

Configuration

Absorption Stage Absorption charge is the second stage of battery charging and provides the

batteries a controlled, constant voltage. During this stage, the current supplied to
the batteries slowly decreases. When this current falls below 2% of the battery
capacity, or when the configurable Absorb Time expires, the charger switches to
the Float or NoFloat stage, depending on the selected charge cycle.

Note: If there are DC loads on the batteries, the charger’s current may never decrease

to a level to initiate the next stage of charging. In this case, the charger would stay in
absorption until the Absorb Time setting is reached.
T o ensure the char ger does not remain in absorption for too long, adjust Absorb Time on
the Charger Settings menu. The timer begins at the start of the absorption stage and
terminates absorption charging if the charge current does not decrease to below 2% of
the battery capacity before the Absorb Time setting expires. The Absorb Time setting
may be increased if the charge cycle continually runs the full Absorb Time in the
absence of DC loads. This is an indication of too large a battery bank for the selected
Absorb Time setting.

Float Stage Float charge maintains a trickle charge on the batteries whenever AC is present on

the inverter’s input. Float charging reduces battery gassing, minimizes watering
requirements (for flooded batteries), and ensures the batteries are in a constant
state of readiness. When three-stage charging is selected, the charger will
automatically switch to the float stage after the batteries have received a bulk and
absorption charge (see Figure 3-4 on page 3–11). The batteries will be maintained
at the default float voltage level for the selected battery type or the voltage
selected under Float Voltage on the Custom Battery Settings menu.

Note: The battery voltage can increase above the float voltage when using an external

charging device such as PV arrays, wind turbines, and micro-hydro generators. Be sure
to include appropriate charge management equipment with all external DC sources.

2-Stage 2-Stage (or No Float) mode differs from an ordinary three-stage charge mode in

that it does not continuously maintain the battery at float voltage. Instead, the XW
Inverter/Charger begins charging the battery in bulk mode whenever the battery
voltage drops below the recharge level. While the battery voltage is above the
recharge level the inverter’s AC transfer switch continues to pass power through
from the utility grid to the loads, but does not actively charge the batteries. 2­Stage mode increases efficiency of utility connected systems by reducing the
amount of power consumed by the inverter and batteries compared to when the
battery is continuously maintained at Float voltage. This feature can extend the
life of most batteries.

To allow Grid Support and Sell Mode to function after battery charging has
completed, it is recommended to set the Charge Cycle to 2-Stage.

Note: If the AC input fails or drops below the lower V ac limit (as set in “AC Settings”),

the complete multi-stage charge cycle (Bulk, Absorption, Float/No Float) restarts once
the source AC returns to an in-tolerance condition. If the batteries are already nearly full,
the charge cycle will take little time to complete.

Equalize Charging the Batteries

Many battery manufacturers recommend periodic equalize charging to level out
the voltage between individual cells, improving battery performance and lifespan.

Over time, the battery’s electrolyte can become “stratified,” causing inactive areas
in the plate material. If this condition is allowed to continue for extended periods,
the battery plates can “sulfate” and become unusable. Equalizing the batteries is a
controlled overcharging method that mixes up the electrolyte and reactivates the
unused areas of the plate material, restoring batteries to a full state of charge.

Consult the battery manufacturer’s recommendation for equalize charging

WARNING: Explosion hazard

Only flooded or vented batteries should be equalize charged. Hydrogen and oxygen gases
are produced when batteries are equalize charged. Provide adequate ventilation and
remove all sources of ignition to prevent explosion.

Important:

(such as a system including multiple XW Inverter/Chargers and Solar Charge Controllers),
there is no system-wide equalization command for all devices. To equalize with multiple
devices, each would have to be enabled individually. Alternatively, equalization can be
performed using only one device. During the equalization process, one device applies the
equalization charge while the other devices continue to operate in synchronized charge
mode, typically in float (three-stage charging) or no-float (two-stage charging).

Configuration

Using Charger Block

The Charger Block feature halts charging on AC1 (Grid) for a period of time each
day. This period of time is defined by the Chg Block Start and Chg Block Stop
settings. In areas where the utility charges variable rates for electricity, it is
preferable to use utility power for charging only during non-peak hours. Charger
Block can prevent utility power from being used for battery charging during peak
billing periods.

During the time period set between Chg Block Start and Chg Block Stop, AC1
(Grid) input continues to be passed through to the loads. Inverter operation
remains unaffected during the charger block period.

During the Charger Block period, no char gi ng on AC1 occurs even if the batteries
discharge below ReCharge Volts setting. However, a generator connected to AC2
(in the absence of utility/AC1 power) or an XW Solar Charge Controller may
charge batteries during the Charger Block period. AC priority must be set to AC2
to charge batteries with a generator connected to AC2 during the Charger Block
period.

If the charger is operating (that is, in Float, Absorption, Bulk or Equalize stage) at
the Chg Block Start time, charging on AC1 stops immediately and the charger
enters an idle state identical to No Float (see “2-Stage” on page 3–12). When the
Charger Block period is over, the charger does not resume the charge stage that
Chg Block Start interrupted. Instead, if the batteries are above the ReCharge Volts
setting, the charger remains idle.

If the batteries have fallen to the ReCharge Volts setting during the Charger Block
period, the XW Inverter/Charger begins a new charge cycle with the Bulk stage
after the Charger Block period has expired (at the Chg Block Stop time).

For example, Charger Block is set to start at 5:00 PM and end at 8:00 PM. If the
XW Inverter/Charger is charging from AC1, charging stops at 5:00. When
Charger Block ends at 8:00, the XW Inverter/Charger does not automatically
resume charging. The unit first measures the battery voltage. If the voltage is
below the ReCharge Volts setting, then the XW Inverter/Charger starts a new
charge cycle from Bulk. If the battery voltage is above the ReCharge Volts setting,
the XW Inverter/Charger remains idle and continues passing through AC to the
loads. The XW Inverter/Charger also keeps measuring the battery voltage as
before to determine whether to start a new charge cycle.

Grid Support

See “Using Charger Block” on page 3–14.

The Grid Support feature allows the XW Inverter/Charger to support local loads
by converting excess capacity from external DC sources connected to its battery
bank. Examples of external DC sources are charge controllers, micro-hydro, and
wind turbines.

For Grid Support to function, Grid Support must be enabled on the Setup menu
and the battery voltage must be above the Grid Supp Volts setting.

There are two modes of operation within Grid Support.
Grid Support enabled, Sell disabled In this mode, available excess DC power

is converted and used to power local loads. No power is exported to the utility. If
the local load demand exceeds the available power from the external DC sources,
power is then drawn from the utility to support the load. However, if the local load
demand is less than the power available from external DC sources, the net excess
power from the external DC sources is not converted and hence not used.

3–18 975-0240-01-01

Peak Load Shaving

Grid Support Settings

Grid support enabled, Sell enabled In this mode all available excess DC
power is first used to power local loads, and any excess is exported to the utility
grid.

Note: Running and Start-up (Peak) currents are limited to the maximum current limits

of the inverter.

Many utilities impose a surcharge on their customers based on the peak load used
by a facility. To reduce utility peak demand charges, the inverter can be
configured (using the Load Shave Amps setting) to limit the maximum draw the
AC loads place on the utility. The inverter can be programmed to provide power
above a specified level, eliminating the surcharge. When the utility current draw
reaches the maximum level, the inverter assists by providing battery powered AC
to the loads.

For Peak Load Shaving to be effective, all loads must be connected to the inverter.
For large loads, multiple (or stacked) inverters may be required.

To further ensure the batteries are able to supplement the power requirements of
the connected load, an additional source of power (solar, wind or hydroelectric) is
recommended.

Peak Load Shaving can also be used in addition to the time-of-use metering.

Time-of-Use Metering

Utilities use time-of-use metering to determine utility charges during peak usage
hours and to impose a surcharge. The XW Inverter/Charger can be configured
(using the Load Shave Start, Load Shave Stop and Charger Block settings) to
overcome these peak charges by using utility power to charge the battery bank
during the inexpensive energy hours and consuming the battery energy during
expensive energy hours.

For example, if Charger Block is set between 9:00 AM and 10:00 PM and Load
Shave is set between 6:00 PM and 9:00 PM, charging on AC1 stops at 9:00 AM
and continues to pass utility AC through to the loads. If charging is required
during the charger block period, and AC Priority is set to AC2, the XW Inverter/
Charger can use any AC source connected to AC2. Loads will transfer to the AC
source on AC2 as well. The inverter connects to the utility grid at 6:00 PM and
supports loads using the batteries. The inverter continues to run until 9:00 PM.
The XW Inverter/Charger then stops supporting the utility grid and passes utility
AC through to the loads. At 10:00 PM utility AC begins maintaining the batteries
based on the battery charger settings.

The above example allows an external renewable energy source to be utilized as a
primary charging source during a desired time window. The charger (using utility
AC connected to AC1) can then be used to supplement the battery charging when
the rates utility rates are low.

975-0240-01-01 3–19

Configuration

When using the system for time-of-use metering, the system should be designed
with a battery capacity large enough to support loads during the entire peak rate
period without reaching the Low Battery Cut Out setting.

T o further ensure the batteries are able to support the loads, an additional source of
power (solar, wind or hydroelectric) is recommended. Depending upon the
capacity of the system, certain heavy loads should only be run during non-peak
periods.

Note: In the event the batteries reach their Low Battery Cut Out voltage, the inverter

will automatically reconnect to the utility grid to maintain the connected load.

3–20 975-0240-01-01

Generator Support Settings

Generator support allows power to be automatically drawn from the batteries to
assist an AC generator to support heavy loads (loads that exceed the available
current from the generator).

Generators have a limited output current and it is possible to reach this limit when
operating heavy loads. The XW Inverter/Charger is designed to assist the
generator when heavy current demands load down the generator by supplying
additional power from the batteries.

In addition, the battery charger can back off its charging current to the batteries so
the combined load of the ch ar ger an d load su pport does not exceed the capacity of
the generator or trip its output breakers or fuses.

Note: Running and Start-up (Peak) currents are limited to the maximum current limits

of the inverter.

Connections Menu

The Connections menu contains additional settings to allow the XW Inverter/
Charger to function as part of a multi-unit networked system.

Setting the connections for a Xanbus-enabled device provides a way of
identifying non-network connections for Xanbus-enabled devices (see Figure 3-7)
and enhancing networked power system mana gement. When connections are set,
devices of different types can detect that they share, for example, a common DC
input source, or a common grid or generator source.

In multi-unit networked systems, inverter/chargers can be stacked to produce
increased charge current. To achieve this functionality, the devices must be
configured to the same DC connection, such as House Battery Bank 1. The
inverter/chargers will collaborate on battery charging by listening to other units on
this shared DC connection.

Important:

Inverter Applications

The XW Inverter/Charger performs differently depending on the AC loads
connected to it. If you are having problems with any of your loads, read this
section.

Inverter Applications

Resistive Loads

Motor Loads

These are the loads that the inverter finds the simplest and most efficient to drive.
Voltage and current are in phase, which means they are in step with one another.
Resistive loads usually generate heat in order to accomplish their tasks. Toasters,
coffee pots, and incandescent lights are typical resistive loads. It is usually
impractical to run larger resistive loads—such as electric stoves and water
heaters—from an inverter due to their high current requirements. Even though the
inverter may be able to accommodate the load, the size of battery bank required
would be impractical if the load is to be run for long periods.

Induction motors (motors without brushes) require two to six times their running
current on start up. The most demanding are those that start under load (for
example, compressors and pumps). Of the capacitor start motors (typical in drill
presses and band saws, for example), the largest you can expect to run is 1 hp.
Universal motors are generally easier to start. Check that the Locked Rotor Amps
(LRA) rating of the motor load does not exceed the maximum surge current rating
of the inverter. Since motor characteristics vary, only testing will determine
whether a specific load can be started and how long it can be run.

If a motor fails to start within a few seconds or loses power after running for a
time, it should be turned off. When the inverter attempts to start a load that is
greater than it can handle, the inverter may shut down from an AC Overload fault.

Troubleshooting

Problem Loads

Very Small Loads

If the power consumed by a device is less than the threshold of the Search mode
circuitry, and Search mode is enabled, the inverter will not run. Most likely the
solution will be to disable the Search mode feature or lower the sense threshold.
Refer to Xantrex Tech Note TN 003 (“Making Sense of Search Mode”) for more
information.

Fluorescent Lights and Power Supplies

Some devices cannot be detected when scanned by Search mode circuitry. Small
fluorescent lights are the most common example. Some computers and
sophisticated electronics have power supplies that do not present a load until line
voltage is available. When this occurs, each unit waits for the other to begin. To
drive these loads, either a small companion load like a light bulb rated for more
than the Search Watts setting must be used to bring the inverter out of Search
mode, or the inverter may be programmed to remain on by disabling the Search
feature. (See “Using Search Mode” on page 3–8.)

Clocks

Searching

You may notice that your clocks may not be accurate. Some of the clocks on your
appliances may reset when the inverter/charger is in Search mode.

When the inverter is in Search mode, it may fail to start some loads even though
the rated wattage on the load is more than the Search Watts setting. Apply an
additional load (companion load) to make the inverter exit Search mode.

Excessive load on output.

Unit is in over-temperature protection
and needs to cool down.

Remote Power Off signal is present.

Open AC output breakers or fuses and
bad output wire connections.

Turn the unit on again.

Check the battery voltage, fuses or breakers
and DC cable connections to the inverter. If
the DC voltage on the inverter’s DC
terminals is correct, have unit serviced.

Reduce loads.

Turn inverter off and allow the unit to cool
and increase ventilation.

Release or reset the Remote Power Off
switch.

Check the Load VAC status on the System
Control Panel Meters screen and check AC
voltage on the inverter AC Out terminal
block.

If the Meters screen shows correct AC
voltage but there is no AC voltage on the
inverter AC Out terminal block, check for
loose connections on the inverter terminal
block. If connections are not loose, the
inverter may need to be serviced.

If there is correct AC voltage on the Meters
screen and on the inverter AC terminal block,
check for open AC output breakers or fuses
and bad output wire connections.

If AC voltage on the Meters screen or
inverter AC terminal block is incorrect, have
unit serviced.

Reduce Search Watts setting, increase load
above Search Watts setting, or turn off
Search Mode on the Setup menu.

If the AC1 LED is on, check inverter output

Troubleshooting

Problem Possible cause Solution

Low AC power output
or low surge power.
INVERT LED is on.
AC inductive loads are
not running at full speed.

Inverter turns on and
then off or doesn’t turn
on at all.

Insufficient DC current being provided
to the inverter to operate the AC loads.

Search Watts setting is too low or high.

Potential problem loads for Search
Mode:

• Incandescent lights have a higher

starting wattage when the filament is
cold than the continuous rating of the
bulb.

• Fluor escent bulbs work the opposite

of incandescent light bulbs. If the
inverter is set to detect a 30-watt load
and a 40-watt fluorescent is switched
on, the inverter will not detect it,
This is because the fluorescent tube
is less than 30 watts until the gas in
the tube ionizes.

• Other loads: Some appliances draw

power even when turned off: TVs
with instant-on circuits, microwaves
with digital clocks, VCRs, and
clocks.

Check the battery voltage, fuses or breakers
and cable connections.

Ensure the battery bank is sufficient (check
for low DC voltage while running the load).

Ensure the cable length and size is correct
(see Installation Guide for correct cable). T ie
the battery cables together to reduce
inductance.

If the search sensitivity is set higher than the
combined loads, then an auxiliary load must
be used to bring the inverter out of Search
Mode before the appliances can be turned on.

If the sensitivity is set lower than the
combination of the loads, the loads will
remain on and excess battery drain will occur
since the inverter won’t ever “idle.”

One solution is to turn the item off at the
wall, use an extension cord with a rocker
switch, a switch at the outlet, or an
appropriate circuit breaker.

Problem Possible cause Solution

Inverter Troubleshooting

In a grid-interactive
mode, the unit is
experiencing excessive
anti-islanding faults. The
utility grid is not
dropping out, yet the
unit is disconnecting
from the grid.

The unit has two sets of AC limits:
adjustable AC qualification limits (as set
on the AC Settings menu), and non­adjustable anti-islanding limits which
are required to have a 5-minute
reconnect delay before returning to grid­interactive mode (Sell Mode or Grid
Support).

While in Sell Mode and in Grid Support,
these two sets of limits are both active.
Whichever limits are set to more
restrictive values (the narrower voltage
and frequency windows) will trip first
when the utility grid varies from normal
values.

If the AC qualification limits are set
outside the fast anti-islanding limits (see
F27, F30, F37 and F40), the unit will
experience less frequent disconnects
from the utility, but when it does
disconnect there will be a 5-minute
delay (minimum) before re-entering a
grid-interactive mode. During this 5­minute delay, all other modes of
operation will be available, assuming the
grid re-enters the user-set frequency and
voltage limits (see “AC Settings” on
page 3–16).

Adjust the AC1 voltage and frequency
settings (see “AC Settings” on page 3–16).
Raise the high voltage and frequency
settings, and lower the low voltage and
frequency settings.

If the AC qualification limits are set
inside the anti-islanding limits, then the
unit will experience more frequent
disconnects from the utility, but when it
does disconnect there will not be a 5
minute delay before entering a grid­interactive mode, assuming the grid re­enters the user-set frequency and voltage
qualification limits.

The impedance of the utility grid is too
high for the power being sold to the grid.
The utility grid impedance may be on
the high end if the installation is too far
from the utility sub station.

AC1/AC2 LED is on,
but will not start
charging
(allow 40 seconds to
synchronize).

AC1 or AC2 LED is
flashing, but will not
start charging
(allow 40 seconds to
synchronize).

1) Charger is disabled on the Setup menu.

2) Charger Block is enabled and the XW
Inverter/Charger is insid e of the Ch arger
Block time window.

3) The XW Inverter/Charger is load
shaving.

4) Charger is set for 2-stage charging and
has completed a full charge cycle.

5) Battery voltage is low and AC voltage
is high; in this case XW is a passive
rectifier charger. For an active charger
operation the following condition should
be met: battery voltage > [0.16 × Vac
input].

AC voltage and frequency at the AC input
terminal are within nominal range, but the
inverter output is not yet synchronized to
the AC source. The unit may be already
synchronized to another AC source, or the
unit is unable to synchronize to the AC
input frequency.

1) Enable the charger .

2) Disable Charger Block if you need to
override this feature.

3) Check the Load Shave settings. If the
load draw from the grid exceeds the Load
Shave Amps setting, the charger will not
operate.

4) No action required. The charger comes
on when the battery reaches the Exit to
Bulk setting. Otherwise use the “Force
Chg” setting on the device setup menu to
force a bulk or float charge.

5) No action required. Wait until AC input
voltage becomes qualified, or allow the
secondary charger to charge the battery.

The unit is operating normally. If the unit
cannot synchronize to unstable generator
input, service the generator.

• correcting the condition that caused the fault.

Clear automatically if the fault condition goes away, just like an

However, if an escalating automatic fault occurs several times
within a defined time period, the escalating automatic fault
becomes a manual fault, requiring user intervention. For
example, if an AC Overload fault occurs three times in five

XW Inverter/Charger Overload Capability

Loads presented to the inverter are seldom constant. T ypically, large loads are operated for
only short periods of time. In order to provide the maximum utility, Xantrex inverters are
allowed to operate at power levels that exceed their continuous power ratings. This graph
shows how loads that are larger than the inverter can sustain continuously can be operated
for useful periods of time.

The length of time that the inverter can operate at high power is limited by temperature.
When large loads are run, the inverter’s temperature increases. At the point where more
heat is created in the inverter than can be dissipated, its ability to operate becomes time
limited.
