Important Safety Information
WARNING
™
Before installing and using your PROwatt 600
Inverter, read and save these safety instructions.
General Precautions
1. Before installing and using the inverter, read all
appropriate sections of this guide and any cautionary
markings on the inverter and the batteries.
2. Do not operate the inverter if it has received a sharp
damaged, see “Warranty” on page 42 and “Return
Material Authorization Policy” on page 43.
3. Do not dismantle the inverter; 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. See
page 43 for instructions on obtaining service.
4. To reduce the risk of electrical shock, disconnect both
AC and DC power from the inverter before working on
any circuits connected to the inverter. Turning off the
front panel On/Off will not reduce this risk.
5. Protect the inverter from rain, snow, spray, and bilge
water.
6. To reduce the risk of overheating or fire, keep the
ventilation openings clear, and do not install the inverter
in a zero-clearance compartment.
vii
Explosive Gas Precautions
Explosive Gas Precautions
1. Batteries generate explosive gases during normal
operation. Be sure you follow all relevant instructions
exactly before installing or using your inverter.
2. This equipment contains components which tend to
produce arcs or sparks. To prevent fire or explosion, do
not install the inverter in compartments containing
batteries or flammable materials or in locations that
require ignition-protected equipment. This includes any
space containing gasoline-powered machinery, fuel
tanks, as well as joints, fittings, or other connections
between components of the fuel system.
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.
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 could 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
or the like to metal, and thus cause a severe burn.
6. If you need to remove a battery, always remove the
positive terminal from the battery first. Make sure all
accessories are off so you don’t cause an arc.

Precautions For Using Rechargeable Appliances
Precautions For Using Rechargeable
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 PROwatt
can power this charger or adapter safely.
Some rechargers for small nickel-cadmium batteries can be
damaged if connected to the PROwatt 600 Inverter. Do not
use the following with the PROwatt 600 Inverter:
•
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 chargers display a warning label stating that
dangerous voltages are present at the battery terminals
AC Wiring Warning
Do not connect the PROwatt 600 Inverter to AC distribution
wiring.
The PROwatt is designed to be connected directly to standard
electrical and electronic equipment. Do not connect it to
household or recreational vehicle AC distribution wiring. Do
not connect it to any AC load circuit in which the neutral
conductor is connected to ground (earth) or to the negative of
the DC (battery) source. Doing so will destroy the unit.

Planning Your Installation
Planning Your Installation
Before doing anything else, you need to determine how you
will be using your PROwatt 600 and on the basis of that,
design a power system that will give the best performance.
The more thorough your planning, the better your power
needs will be met. In particular, you need to:
•
•
Calculate your battery requirements
Choose an effective charging system
Calculating Battery Requirements
Battery type and size strongly affect performance of the
PROwatt 600. Therefore, you must identify the type of loads
your inverter will be powering. Once you know how much
power you will be using, you can determine how much
battery capacity you need. Xantrex recommends that you
purchase as much battery capacity as possible.
Consult Appendix B “Battery Types and Sizes” on page 27
for a detailed explanation of how to determine the appropriate
number and size of batteries for your installation.
CAUTION
The PROwatt 600 must only be connected to a
battery that has a nominal output of 12 volts. It will
not operate when connected to a 6 volt battery and
will be damaged if connected to a 24 volt battery.
Choosing a Charging System
Your charging system must be appropriate for your inverter
installation. This will ensure that power is available when
you need it and that your batteries remain in top condition.
Inadequate charging will degrade system performance, and
the wrong type of charger will reduce battery life.
Consult Appendix C “Alternators and Charging Systems” on
page 37 for information that will explain how to design an
effective charging system.
7
Choosing a Location
Choosing a Location
WARNING
The PROwatt 600 contains components that tend to
produce arcs or sparks. To prevent fire or explosion,
do not install the PROwatt in compartments
containing batteries or flammable materials or in
locations that require ignition-protected equipment.
WARNING
To reduce the risk of fire, do not cover or obstruct the
ventilation openings. Do not install the PROwatt 600
in a zero-clearance compartment. Overheating may
result.
The PROwatt 600 Inverter should only be installed in a
location that meets these requirements:
Dry
Do not allow water or other liquids to drop or splash
on the PROwatt 600.
Cool
Ambient air temperature should be between 32º F
and 105º F (0º C and 40º C)—the cooler the better
within this range.
Ventilated
Safe
Leave at least 2 inches (5 cm) clearance around the
PROwatt 600 for air flow. Ensure that ventilation
openings at the front and rear are not obstructed.
Do not install the inverter in the same compartment
as batteries or in any compartment capable of storing
flammable liquids like gasoline.
Close to
battery
DC cables must be shorter than 4 feet (1.2 m) each.
Longer AC wires are preferable to longer DC wires.
Protected
Do not mount the inverter where it will be exposed to
from battery battery gases. These are very corrosive, and
gases
prolonged exposure will damage the inverter.
8
Mounting the Inverter
Mounting the Inverter
To mount the PROwatt 600 Inverter:
1. Turn off the inverter’s On/Off switch.
2. Select an appropriate mounting location and orientation.
The PROwatt must be oriented in one of these two ways:
• Horizontally on a vertical surface. (The ventilation
openings must not point up or down.)
• On or under a horizontal surface
3. Mark the positions of the four mounting screws, and
pilot-drill the mounting holes.
4. Fasten the inverter using corrosion-resistant hardware
sized #10 or larger.
Connecting the Chassis Ground
WARNING: Electrical Shock Hazard
Never operate the PROwatt 600 without
connecting the chassis to ground. Electrical shock
hazard could result.
This inverter does not provide isolation between
the DC and AC circuits. Therefore the AC line and
neutral are both “hot” relative to battery negative.
The ground pins of the AC output receptacles are
connected to the battery negative as is the chassis
of the inverter.
The PROwatt 600 has a screw terminal labeled CHASSIS
GND on the rear panel as shown in Figure 1. This is to be
used to connect the inverter’s chassis to the ground. To
connect the chassis to ground, follow the guidelines below.
9
Connecting DC Cables
Grounding Locations
The chassis ground terminal must be connected to a
grounding point, which varies depending on where you
install the PROwatt 600. Follow the guidelines that
correspond to your type of installation.
Vehicle Connect the CHASSIS GND screw to the vehicle’s
chassis using 8 AWG copper wire (preferably with green/
yellow insulation).
Marine Connect the CHASSIS GND screw to the boat’s DC
grounding bus or the engine’s negative bus using 6 AWG
copper wire that has insulation rated at 90º C.
Fixed Location (residential, for example). Connect the
CHASSIS GND screw to your system’s DC grounding point
using 6 AWG wire. The system’s grounding point will
usually be the AC service entrance grounding point or a
separate ground rod. For a solar PV (photovoltaic)
installation, this is usually the same ground rod used to
ground the PV array.
Connecting DC Cables
Proper cables and wiring are essential to effective operation
of the PROwatt 600. Because the PROwatt 600 has a low
voltage, high current input, low-resistance wiring between
the battery and the inverter is essential to deliver the
maximum amount of usable energy to your load.
Cabling Guidelines
Deviating from these guidelines will cause excessive voltage
drop or melting of the cable and/or connectors. The inverter
may also shut down or fail to operate some loads.
•
Make sure each cable between the inverter and the
battery is no longer than 4 feet (1.2 m).
•
Use 4 AWG copper (90º C insulation rating).
10
Connecting DC Cables
•
than copper cable of the same size, and it is difficult to
make good, low-resistance connections to aluminum.

Cabling Procedure
To connect the DC cables:
1. Cut the cables to the correct length.
2. Strip the appropriate amount of insulation from one end
of each cable and attach the connectors that will join the
cables to the battery, battery isolator switch, or fuse
block. The connectors you use must create a permanent,
low-resistance connection.
12
Connecting DC Cables
If you are using crimp connectors, use the tool
recommended by the terminal manufacturer. Make sure
no stray wires protrude from the terminal. (You can also
have the crimp connectors attached by the company that
sells you the cable.)
3. Strip about 1/2 inch (1.25cm) from the ends of the cables
that will be connected to the inverter.
4. Install a fuse and fuse holder in the cable that will be used
for the positive side of the DC circuit. The fuse must be
as close to the battery as possible, must be rated for DC
circuits, rated 80A max, and have a short-circuit interrupt
rating that exceeds the short-circuit current available
from the battery.
Xantrex recommends a Bussman ANL-80 fuse or a
Gould type A3T80 Class T fuse, or equivalent for
installations requiring a “code fuse”.
5. Insert the stripped ends of the cables into the cabling
terminals on the rear of the inverter and tighten the
screws securely. The red terminal is positive (+); the
black terminal is negative (–). See Figure 2.
6. Attach the connector on the negative cable to the
negative battery terminal. Make a secure connection.
Loose connectors cause excessive voltage drop and may
cause overheated wires and melted insulation.
CAUTION: Reverse Polarity
Power connections to the PROwatt 600 must be
positive to positive and negative to negative.
A reverse polarity connection (positive to negative)
will blow a fuse in the inverter and may cause
permanent damage. Your warranty does not cover
damage caused by a reverse polarity connection.
13
Connecting DC Cables
7. Before proceeding, make sure that the cable you have just
installed connects the negative terminal of the inverter to
the negative terminal of the battery.
WARNING: Explosion or Fire
Do not complete the next step if flammable fumes
are present. Explosion or fire may result.
Thoroughly ventilate the battery compartment
before making this connection.
8. Connect the cable from the positive (red) terminal of the
PROwatt 600 to the positive terminal of the battery.
This is the last cable connection. A spark is normal when
you make it.
9. If you have installed a battery selector switch, use it to
select one of the batteries.
10. Turn on the inverter’s On/Off switch.
11. Check the inverter’s front panel. The POWER indicator
should be on. If it is not, or if the FAULT indicator is on,
check your battery and the connections to the inverter.
14
Turning the Inverter On and Off
Turning the Inverter On and Off
The On/Off switch on the front panel turns the control circuit
in the PROwatt 600 on and off.
To turn the inverter on or off:
•
Turn the On/Off switch or off.
CAUTION
The inverter’s On/Off switch does not disconnect
power from the PROwatt.
When the switch is Off, the inverter draws no current from
the battery.
Operating Several Loads at Once
If you are going to operate several loads from the
PROwatt 600, turn them on separately after you have turned
the inverter on. This will ensure that the inverter does not
have to deliver the starting current for all the loads at once.
Turning the Inverter Off Between Charges
When the switch is on but no power is being supplied to a
load, the inverter draws less than 300 mA from the battery.
This is a low current draw. It would take more than a week to
discharge a 100 Ah battery at this current, so you don’t have
to worry about excessive drain on your battery if you leave
the inverter switched on for a few days.
If you are not planning to recharge your battery within a week
or so, turn the inverter off.
16
Reading the Front Panel Indicators

Over Temperature
Shutdown
The PROwatt 600 has overheated and shut
down. The inverter may have overheated
because it was operated at power levels
above its 600W continuous output rating or
because it was installed in a location that
does not allow it to dissipate heat properly.
Turn the inverter off and then back on after
it has cooled down.
Note: To cool the inverter quickly, remove
any loads, and leave the switch on to keep
the fan running.
Overload Shutdown A severe overload has caused the
PROwatt 600 to shut down.
Turn it off for 4–5 seconds, correct the fault
condition, and turn it back on. Do not turn
the inverter on again unless you have
corrected the fault condition (removed the
load or unplugged it).

Common Problems
Common Problems
WARNING
Do not dismantle the PROwatt 600 Inverter. It does
not contain any user-serviceable parts. Attempting
to service the unit yourself could result in an
electrical shock or burn.
Buzz in Audio Equipment
Some inexpensive stereo systems emit a buzzing noise from
their loudspeakers when operated from the PROwatt 600.
This occurs because the power supply in the audio system
does not adequately filter the modified sine wave produced
by the PROwatt. The only solution is to use a sound system
that has a higher quality power supply.
Television Reception
When the PROwatt 600 is operating, it can interfere with
television reception on some channels. If interference occurs,
try the following:
1. Make sure the chassis ground screw on the rear of the
PROwatt is solidly connected to the ground system of
your vehicle, boat, or home.
2. Make sure that the television antenna provides an
adequate (“snow-free”) signal and that you are using
good quality cable between the antenna and the
television.
3. Keep the cables between the battery and the PROwatt as
short as possible and twist them together with two to
three twists per foot. (This minimizes radiated
interference from the cables.)
4. Move the television as far away from the PROwatt as
possible.
5. Do not operate high power loads with the PROwatt while
the television is on.

The batteries you use strongly affect the
performance of the PROwatt 600 Inverter. It
is important to connect the inverter to the
correct size and type of battery.
The information in Appendix B will help
you select, connect, and maintain batteries
that are most appropriate for your
application.
27
Battery Types
Battery Types
Automotive Starting Batteries
Purpose
The lead-acid battery you are most familiar with is probably
the starting battery in your automobile. An automotive
starting battery is designed to deliver a large amount of
current for a short period of time (so it can start your engine).
Only a small portion of the battery’s capacity is used to start
the engine, and it is quickly recharged by the running engine.
This type of battery is not designed for repeated cycles where
the battery is almost completely discharged and then
it will wear out rapidly.
Light Loads
If your installation uses relatively low power loads (that is,
power consumption of 300 W or less) and relatively short
operating times before recharging (one hour or less), you can
connect the PROwatt 600 directly to the vehicle starting
battery. See Figure 5.

Deep-Cycle Lead-Acid Batteries
Purpose
Deep-cycle lead-acid batteries are designed for deep
discharge service where they will be repeatedly discharged
and recharged. They are marketed for use in recreational
vehicles, boats, and electric golf carts—so you may see them
referred to as RV batteries, marine batteries, or golf cart
batteries.
Average and Heavier Loads
For most applications of the PROwatt 600 Inverter, Xantrex
recommends that you use one or more deep-cycle batteries
that are separated from the vehicle’s starting battery by a
battery isolator.
A battery isolator is a solid-state electronic circuit that allows
equipment to be operated from an auxiliary battery without
danger of discharging the vehicle’s starting battery. During
vehicle operation, the battery isolator automatically directs
the charge from the alternator to the battery requiring the
charge. Figure 6 shows a battery isolator.
Battery isolators are available at marine and RV dealers and
most auto parts stores.
Battery Size
CAUTION
The PROwatt 600 must only be connected to
batteries with a nominal output voltage of 12 volts.
The PROwatt 600 will not operate from a 6 volt
battery and will be damaged if connected to a 24
volt battery.
Importance of Battery Size
Battery size or capacity is as important as the battery type
you use.
29
Battery Size
Battery Capacity Standards
A number of different standards are used to rate battery
energy storage capacity. Automotive and marine starting
batteries are normally rated in cranking amps. This is not a
relevant rating for continuous loads like an inverter. Deep-
cycle batteries use a more suitable rating system, either
“amp-hours” (“Ah”) or “reserve capacity” in minutes.
Battery Reserve Capacity Battery reserve capacity is a
measure of how long a battery can deliver a certain amount of
current—usually 25 amps. For example, a battery with a
reserve capacity of 180 minutes can deliver 25 amps for 180
minutes before it is completely discharged.
Amp-hour (Ah) Capacity Amp-hour capacity is a measure
of how many amps a battery can deliver for a specified length
of time—usually 20 hours. For example, a typical marine or
RV battery rated for 100Ah can deliver 5 amps for 20 hours
(5 A x 20 hours = 100 Ah).
Actual Battery Capacity Actual battery capacity decreases
as discharge current increases. A battery rated at 100Ah
which can deliver 5 A for 20 hours may deliver 20 A for only
4 hours, resulting in an actual capacity of 80 Ah. For this
reason, it is difficult to compare rated Ah capacity with
battery reserve capacity. For example, a battery with a reserve
capacity of 180 minutes has the following calculated Ah
capacity:
is rated at the discharge current required to get 20 hours of
operation (about 5 A).
To calculate the battery capacity you require, read
“Estimating Battery Requirements” on page 31 and “Battery
Sizing Example” on page 32, and then complete the “Battery
Sizing Worksheet” on page 33.
30
Estimating Battery Requirements
Estimating Battery Requirements
To determine the battery capacity you require:
1. Determine how many watts are consumed by each
appliance that you will be operating from the
PROwatt 600. You can normally find this on a label on
the product. If only the current draw is given, multiply it
by 115 to get the power consumption in watts.
2. Estimate how many hours each appliance will be
operating each day.
3. Calculate the daily watt-hours needed for each appliance.
4. Add the total number of watt-hours needed for all the
appliances and multiply it by the number of days between
charges.
5. Divide the total watt-hours of AC load between charges
by 10. This gives the battery Ah used between charges.
6. Double the total Ah used between charges to get the
recommended battery size in Ah.
See the battery sizing example that follows.

This example illustrates how quickly your battery needs can
escalate. To reduce the required battery size, you can
conserve energy by eliminating or reducing the use of some
loads or re-charge more frequently.
When sizing your battery, resist the temptation to skip the last
step of this calculation (multiplying by 2). More capacity is
better since you will have more reserve capacity, be better
able to handle large loads and surge loads, and your battery
won't be discharged as deeply. Battery life is directly
dependent on how deeply the battery is discharged. The
deeper the discharge, the shorter the battery life.

As your power requirements increase, you may need to use
more than one battery to obtain sufficient capacity. Read
“Two Batteries Connected In Parallel” to determine whether
two batteries are appropriate for the applications you intend
to power.
33
Two Batteries Connected In Parallel
Two Batteries Connected In Parallel
Two identical batteries can be connected positive (+) to
positive (+) and negative (–) to negative (–) in a parallel
system. A parallel system doubles capacity and maintains the
voltage of a single battery. Figure 6 shows two batteries
connected in parallel.
CAUTION
Do not make a parallel connection between
batteries made by different manufacturers,
different types of batteries, or batteries that have
different Ah ratings. Decreased battery life and
improper charging will result.
Do not connect an old battery to a new one.

Battery Tips
WARNING
Review “Precautions When Working With
Batteries” on page viii before you work with the
batteries in your system.
Explosive/Corrosive Gases Lead-acid batteries may emit
hydrogen, oxygen, and sulfuric acid fumes when recharging.
To reduce the risk of explosion:
•
•
•
Vent the battery compartment to prevent the
accumulation of gases.
Do not install electronic or electrical equipment in the
battery compartment.
Do not smoke or use an open flame when working
around batteries.
Temperature Sensitivity The capacity of lead-acid batteries
is temperature sensitive. Battery capacity is rated at 77º F
(25º C). At 0º F (–20º C), the Ah capacity is about half the
rated capacity. Temperature should be considered when you
design your system.
Low Temperatures If extremely low temperatures are
expected where the inverter is going to be located, you should
consider a heated equipment room. If the system is located in
an unheated space, an insulated battery enclosure is
recommended.
High Temperatures The batteries should also be protected
from high temperatures. These can be caused by high
ambient temperatures, solar heating of the battery enclosure,
or heat released by a nearby engine or generator. High battery
temperature results in short battery life and should be avoided
by ventilating the enclosure and reducing the external heat
source by shading and insulation.
35
Battery Tips
Discharged Batteries Do not leave batteries in a discharged
state for more than a day or two. They will undergo a
chemical process (sulfation) that can permanently damage the
battery. As well, batteries self-discharge over a period of
three to six months, so they should be recharged periodically
even if they are not being used.
Electrolyte Level If your batteries are not the “maintenance-
free” type, check the electrolyte level at least once a month.
Excessive fluid loss is a sign of overcharging. Replenish the
electrolyte using distilled water only.
Battery Connections Connections to battery posts must be
made with permanent connectors that provide a reliable, low-
resistance connection. Do not use alligator clips. Clean the
connections regularly and prevent corrosion by using a
protective spray coating or vaseline.
Battery State of Charge You can measure battery state of
charge with a hydrometer or, more easily, with a voltmeter.
Use a digital voltmeter than can display tenths or hundredths
of a volt when measuring 10 to 30 volts. Make your
measurements when the battery has not been charged or
discharged for several hours. For a deep-cycle battery at
77º F (25º C), use the following table:
Battery Voltage State of Charge
12.7–13.0
12.5–12.6
12.3–12.4
12.1–12.2
11.9–12.0
100%
80%
60%
40%
20%
36
Charging System Requirements
Charging System Requirements
Your charging system should be capable of delivering a
charging current equal to 10–25% of the amp-hour capacity
of your battery. For example, if you have a 200 Ah battery,
the charging system should be able to deliver 50 amps. The
charging system must also be able to charge each 12 volt
battery up to approximately 14.4 V and then drop back to a
“float” voltage of 13.5–14 V (or shut off).
CAUTION
Never operate the PROwatt 600 directly from an
alternator. To work properly the PROwatt must be
connected to a battery or a well-regulated, high-
current DC power supply.
Charging With an Engine Alternator
The following information will let you determine whether
your vehicle’s standard alternator will be adequate by itself,
whether you should install an alternator controller, or whether
you need a high-output alternator.
Using Your Vehicle’s Standard Engine Alternator
A typical engine alternator (12 volts) may not be able to meet
these requirements if your system uses large capacity
batteries. Alternators are typically rated for the current they
can deliver when they are cold. In use, alternators heat up,
and their output current capability drops by as much as 25%.
Therefore, standard alternators with ratings of 40–105 A will
only deliver a maximum of 30–80 A in actual use and will
deliver even less as battery voltage rises. Many alternators
cannot produce more than 13.6 V when they are hot. As a
result, a standard alternator may not be able to charge a large
battery quickly and completely.
Two solutions are to install an alternator controller or to
install a high-output alternator.
38
Charging From AC Power
Using an Alternator Controller
If your regular alternator is inadequate by itself, you can
install an alternator controller that will bypass the voltage
regulator and boost the alternator’s output voltage during
charging. This will increase the alternator’s charging rate at
higher battery voltages and ensure more rapid and complete
charging. Alternator controllers are available from marine
product dealers.
Using a High-Output Alternator
Heavy-duty alternators rated from 100–140A can replace
standard alternators and produce the higher current and
voltage required to charge multiple battery systems. They are
available from RV and marine dealers as well as auto parts
suppliers.
Charging From AC Power
When recharging from AC power, use a good quality marine
battery charger or RV converter that meets the requirements
outlined in “Charging System Requirements” on page 38. For
information about battery chargers manufactured by Xantrex,
see the Xantrex web site at www.xantrex.com
Do not use chargers intended for occasional recharging of
automotive starting batteries. These chargers are not intended
for continuous use.
39
Charging From Alternative Energy Sources
Charging From Alternative Energy Sources
Your batteries can also be recharged from alternative energy
sources such as solar panels, wind, or hydro systems. Make
sure you use the appropriate battery charge controller for
your particular energy source.
CAUTION
N ever operate the PR O w att 600 Inverter directly from
an energy source such as a solar panel. The PR O w att
m ust be connected to a battery or a w ell-regulated, high-
current D C pow er supply to w ork properly.
