Important Safety Information
WARNING
Before using your Inverter/Charger, read and save these safety
instructions.
General precautions
1. Before using the inverter/charger, read all appropriate sections of
this guide and any cautionary markings on the inverter and the
batteries.
2. Use only a grounded AC extension cord when connecting to AC
input power (shorepower). Do not remove or attempt to defeat the
ground connection to any shorepower source in any way.
3. If possible, plug the inverter/charger into an AC source outlet that is
protected by a Ground Fault Circuit Interrupting (GFCI) device;
either a breaker or outlet.
4. Do not operate the inverter/charger if it has received a sharp blow,
been dropped, or otherwise damaged. If the unit is damaged, return
it to your authorized Volvo dealer.
5. Do not dismantle the inverter/charger; it contains no user-
serviceable parts. Attempting to service the unit yourself could
cause electrical shock or fire. Internal capacitors remain charged
after all power is disconnected.
6. To reduce the risk of electrical shock, turn off the inverter/charger
from the remote switch, then disconnect both AC (shorepower) and
DC (battery) power from the unit before working on any circuits
connected to it. Turning off the remote On/Off switch alone will not
reduce this risk.
Precautions when working with batteries
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.
v
Important Safety Information
3. Never smoke or allow a spark or flame near the engine or battery.
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 cause an explosion.
5. Remove metal items like rings, bracelets, and watches when
working with lead-acid batteries. These batteries produce a short-
circuit current high enough to weld a ring, other metal jewellery or
tools, thus causing severe burns.
6. If you need to remove a battery, always remove the negative
terminal from the battery first. Make sure all accessories are off so
you don’t cause an arc.
7. Before making the final connection to a battery, be sure the polarity
is correct; negative-to-negative, and positive-to-positive.
8. When you are making the final connection to a battery, you will see
a spark and hear a loud pop. This is normal.
Precautions for using appliances
Most battery-operated equipment uses a separate charger or transformer
that is plugged into an AC receptacle and produces a low voltage output.
If the label on the AC adapter or charger states that the adapter or
charger produces a low voltage AC or DC output (less than 30 volts),
the inverter/charger can power this charger or adapter safely.
Some rechargers for small nickel-cadmium batteries can be damaged if
connected to the inverter/charger. Do not use the following loads and
appliances:
•
Small battery-operated appliances like flashlights, razors, and night
lights that can be plugged directly into an AC receptacle to
recharge.
•
Chargers for battery packs used in hand power tools. These types of
chargers display a warning label stating that dangerous voltages are
present at the battery terminals.

Introduction
Operating features
Inverter/charger
The inverter/charger operates as an inverter and as a charger depending
upon the operational conditions. When the unit is inverting, it is said to be
in invert mode and is referred to as an inverter. When the unit is charging,
it is in charge mode and is referred to as a charger.
The unit can only operate in charge mode when external AC power
referred to as “shorepower” is connected.
Inverter
features
Xantrex HD offers the following inverter features:
•
Ability to run many of the same appliances that you use at home
You can operate TVs, VCRs, satellite receivers, computers, hair
dryers, and small power tools for example. You can also run multiple
loads up to 1000 watts in total.
•
•
Surge capability
Xantrex HD will manage loads up to 3000 watts for short periods of
time as long as the peak current is less than 36 A peak.
Low voltage shutdown
The inverter shuts off when your batteries reach a predetermined
voltage set in the microprocessor to ensure you will always have
enough engine starting power. Low voltage shutdown also monitors
frequency and voltage, and protects against overload, short circuits
and over-temperature.
•
Automatic shutdown when the unit does not detect a load greater than
20 watts for 24 hours
This feature prevents the inverter from draining the batteries if it is
left on without a load.
1–4
Operating features
Charger
features
Xantrex HD offers the following charger features:
•
50 amp charging, when shorepower is connected, to ensure your truck
batteries are always charged
•
Automatic transfer to invert mode
When your truck’s AC shorepower cord is disconnected, the unit
automatically switches to invert mode. When AC shorepower is
available again, the inverter automatically switches to charging/pass-
through mode.
•
Load management capability which temporarily reduces charging
current to the batteries when a large AC load is applied to the inverter
output. This capability helps reduce the chance of tripping the
shorepower breaker.

Operation
Planning for AC loads
AC load
AC load refers to an AC product you want to operate from the
inverter/charger. Loads include most products that you can plug into a
standard 120 volt household electrical outlet.
Variables
affecting AC
loads
The Xantrex HD inverter/charger inverter can power a wide range of
loads. The size of the load and the length of time you can operate it
depends on variables such as
•
•
•
type of load
ambient temperature
size, state of charge, temperature, and condition of batteries.
The larger your battery capacity and the higher the state of charge, the
longer the inverter/charger can run your AC loads. Battery capacity is
reduced as battery temperature lowers.
Type of loads
AC loads
The way in which an AC load draws power may determine how
effectively it can be powered from the inverter/charger.
Resistive loads
Inductive loads
Toasters, coffee pots and incandescent lights are examples of loads which
do not need a high start-up current to start running. They use a resistive
heater element to generate heat or light. They are the simplest and most
efficient for an inverter/charger to run. Large resistive loads, such as
electric stoves and water heaters, are impractical since their high current
demands quickly drain the batteries.
TVs, VCRs, stereos, computers, and electric motors (power tools,
vacuum cleaners, for example) are examples of AC loads which surge on
start up, that is, they require a high startup current compared to a resistive
load such as toasters or coffee pots. These loads are known as inductive or
electronic loads. Depending upon the size of the motor, it can take as
much as six times its running current to start it than it does to keep it
running once it has started. This surge can sometimes exceed the
inverter/charger’s maximum output rating and the inverter will shut
down.
2–2
Planning for AC loads
DC loads
DC loads are those that run off the 12 V electrical system on the truck. A
few examples of DC loads are:
•
•
•
•
marker lights, headlights, cab lighting, other lights using DC power
DC refrigerators
CBs
factory-installed radios or sound systems
DC loads and the inverter/charger both rely on the batteries for power.
Many DC loads running at one time will shorten the operating times of
AC loads.
Problem loads
These are loads you should not operate from inverter/charger because
they may be damaged or may not operate properly:
•
•
•
dimmer switches
some small rechargeable hand power tool chargers
small battery-operated appliances such as flashlights, razors, night
lights
•
variable speed motors
Ambient temperature
Ambient
The ambient temperature, that is, the air temperature around the
temperature
inverter/charger will affect its output power.
The air temperature around the inverter may be much hotter than away
from the vehicle. If your truck is standing on hot pavement, the
temperature may be quite high near the inverter.
Temperature
and power
example, at 77 °F (25 °C) the unit delivers 1000 watts for as long as you
have sufficient battery power. At 104 °F (40 °C) it delivers 1000 watts for
up to 10 minutes before shutting down or 750 watts continuous, or 2000
watts for 2 1/2 minutes.
Figure 2-1 shows the relationship between ambient temperature and the
length of time the unit will supply an output power level. Choose the
curve with temperature range most closely approximating that of the
inverter/charger location, then look for the time in minutes. The
2–3
Operation
intersection of the time and temperature will indicate approximately the
output power of the unit. For example, between – 40 °F (– 40 °C) and
77 °F (25 °C), you will get 3000 watts for approximately two minutes or
2500 watts for 3 minutes.

Calculating size of an AC load
Operating time
To determine how long you can run your appliances:
1. List all the AC loads you think you will use and determine their
power requirement. You can usually find this information on a label
near the power cord on the appliance.
2. Look in Table 2-1 to find its operating time or the operating time of a
down after that time so the battery is not drained past a safe level.
3. To find the running time for several appliances running
simultaneously add the total watts of the appliances and look for an
appliance with similar power requirement in Table 2-1.

Planning for AC loads
Factors
Consider these factors when you are calculating loads:
affecting load
•
•
•
Loads that exceed 1000 watts may be run for a short time (less than
five minutes)
Loads which run continuously, (reading light, TV, computer) should
not exceed more than 1000 watts in total
Poor battery condition, low battery capacity, low battery temperature,
and high ambient temperature will shorten the operating times listed
in the table
•
The presence of DC loads will reduce the operating times

Planning for AC loads
Driving the truck while operating AC and DC loads
Recharging
Driving your truck does not guarantee that the battery is being fully
recharged by the alternator if you are running a combination of large AC
and DC loads.
The alternator must provide more power than the combined DC and AC
loads draw for your battery to fully recharge.
Example
This example shows what happens if the alternator is overloaded.

Figure 2-2 AC and DC loads powered by the alternator
The alternator is charging at 130 amps while the truck is being driven at
highway speeds and there is a 1000 W (AC) load.
2–7
Operation
The efficiency of the inverter/charger is approximately 90%, which means it
is drawing about 1100 W (DC) from the battery or 92 amps. This leaves
38 amps for all DC loads. If the DC loads require more than 38 amps, the
battery will actually discharge even though the alternator is running.
Indication
If the alternator is overloaded the:
•
battery voltage gauge on the dashboard begins dropping from
approximately 14 V towards 12 V
•
•
•
inverter LED signals a low battery with a slow blink
inverter shuts down at 11.8 V and AC loads will stop operating
battery voltage gauge will climb again as the alternator now has enough
power to charge the battery
Solutions
Comment
You can reduce the AC or DC load on the battery or, for continuous
operation of large AC and DC loads you can consider installing a larger
alternator.
Small alternator overloads may not be immediately noticeable and can take
several hours to discharge the batteries. Large overloads will discharge the
battery in a shorter time.
At low engine RPMs the alternator current will drop significantly causing
alternator overload to occur even with reduced AC and DC loads.

If the LED is blinking once every two seconds (very
slow blink), it means the unit has shut down to avoid
draining the batteries.
A fast-blinking Inverter LED light indicates a unit
fault. Refer to Chapter 4, “Troubleshooting” for more
information.
Note: Some switches may also have a center position. The center position also
enables the inverter.

Operating the Inverter/Charger
Operating the Inverter/Charger
This section provides guidelines for operating the Xantrex HD.
Turning the inverter on and running loads
To run loads:
•
•
Put the switch in the On position by pressing down.
Check that the inverter LED is illuminated and AC LED is off if you are
not connected to shorepower.
•
Connect appliances one at a time to the inverter. Don’t connect too
many high-surge appliances at once. You may notice some appliances
halt or dim momentarily while another is starting up.
Running in extremes of hot or cold temperatures
Hot
In extremely hot conditions, the inverter may shut down sooner than it
would in normal or cold temperatures. The unit may be hotter than the
outside air temperature when parked on hot pavement, for example.
When the ambient temperature is high, reduce the number of loads.
Cold
In extreme cold temperatures, your batteries may have less stored energy. At
0 °F (– 18 °C) your battery has only half the standby power than it has at
77 °F (25 °C).
Restarting after a shutdown
If the appliances stop operating suddenly, it usually means that the battery
voltage is too low or you have drawn too much power for too long. Try
restarting the inverter by turning the switch off, then on again. If you are
running several loads, try disconnecting one or two of them. If it doesn’t
start right away, let the inverter rest a few minutes, then try again. The
batteries should be recharged as soon as possible. If it still refuses to power
your loads, start the vehicle to charge the batteries.
Note: Turning the switch off, then on again to restart after a shutdown
should only be considered a temporary measure. The batteries likely
need to be recharged.
2–11
Operation
Battery charging
When you are connected to shorepower, the AC LED is illuminated and the
unit is both passing power through to the appliances and charging the
batteries. To avoid low voltage problems, make sure your connection cord to
shorepower is not too long and that it is heavy enough to support the loads
you are running. A 14 or 12 gauge extension cord is recommended.
If the AC LED flashes slowly (about twice per second), this means the AC
voltage is out of range and your batteries are not charging.
Using shorepower
If you are running too many appliances you may either trip the 15 amp truck
breaker or the shorepower breaker. Reduce the load and reset the affected
breaker.
Note that the charger will automatically reduce battery charging if other AC
loads are connected. This helps to prevent nuisance tripping of the
shorepower breaker.
Miscellaneous hints
Automatic
shutdown
The inverter automatically turns off if it has not detected any AC loads for
24 hours or the loads are so small the inverter cannot detect them, such as an
alarm clock or very small television (less than 10-20 watts).
Output
power
Remember that the total output of the inverter/charger is 1000 watts and not
1000 watts per outlet (if there is more than one).

Note: The Xantrex HD does not provide any warning before it shuts
down. If you need to operate a critical AC load, be sure there are no
heavy loads connected and that the batteries have been recently charged.

Troubleshooting reference (Continued)
Symptom
Possible Problem
Remedy
Loads stop operating without
warning after they have been
running for awhile
Too many appliances have
reduced battery voltage to
shutdown level
Reduce number of loads. Allow
inverter to cool and restart. Start
the truck to recharge the batteries.
Shorepower not connected
Ambient temperature is too
high
Disconnect appliances and let the
unit cool down
Inverter will not work even
after toggling switch and
batteries are charged and the
inverter is cold
Remote switch may be
disconnected at the unit (not
likely)
Check that the remote switch is
firmly connected
Fuse on the unit (shown in
Figure 1-1) may have blown
(not likely)
Replace fuse or return unit to an
authorized Volvo dealer
AC voltage at receptacles
reads low
Wrong type of volt meter being Use a true RMS meter
used
In inverter mode, times to
shutdown are getting shorter
for the same kind of AC load
Bad battery cable or corroded Check cables and connectors
battery terminals
Batteries too old or damaged
Replace batteries
Blinking lights on the remote switch
This table describes the different sequences of blinking lights you may
encounter when the inverter is enabled (switch is on) or the unit is
charging (switch is off). Light sequences are described as follows:
L
Fast blink
Light is on for 1/4 second and off for 1/4 second
Light is on for 1/2 second and off for 1/2 second
Light is on for one second and off for one second
Slow blink
Very slow blink

Delay on transfer from the inverter
to shorepower
AC power is not in range (outside
100 to 130 Vac range)
Battery is not being charged. AC
output load may be too great
Extension cord to shorepower may
be too long or not of sufficient
conductor size, resulting in voltage
drop
Table 4-3 explains the inverter LED flashing pattern when the unit is in
invert mode or in charge mode.

Calling your authorized Volvo dealer
Calling your authorized Volvo dealer
If none of the troubleshooting suggestions work, you will need to call
your authorized Volvo dealer. If possible, note the circumstances
surrounding the failure. They may help the service technician diagnose
the problem quickly.
How long have you had
the inverter?
Serial number
Battery types and sizes
Appliances running at
shutdown
Were the LEDs flashing
and if so, what pattern
(slow blinks? fast blinks?)
Was the ambient
temperature extremely hot
or cold?
Were any DC appliances
affected?
Has this happened before?
