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.

• Supports multi-mode grid-tie operation

• 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.

Monitoring Battery Level

The row of five LEDs indicates the approximate capacity of the batteries
connected to the system. The capacity reading is based on current-compensated
battery voltage.

There are four battery states: empty, low, medium, and full. When the battery
capacity is empty , no LEDs are lit. The battery is considered empty when its depth
of discharge exceeds approximately 50%. When the battery capacity is low, the
leftmost two LEDs are lit. When the battery is at medium capacity, the leftmost
four LEDs are lit. When the battery capacity is full, all five LEDs are lit.

Using the Standby Button

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.
