Important Safety Information

WARNING

Before installing and using your Prowatt 1000, be sure to read
and save these safety instructions.

General Precautions

1. Before installing and using the inverter, read all appropriate sections
of this guide as well as all instructions and cautionary markings on
the inverter and the batteries.

2. Do not operate the inverter if it has received a sharp blow, been
dropped, or otherwise damaged. If the unit is damaged, see

“War ranty” on page D–2 and “Return Material Authorization
Policy” on page D–3.

3. Do not dismantle the inverter; it contains no user-serviceable
components. Attempting to service the unit yourself could cause
electrical shock or fire. Internal capacitors remain charged after

all power is disconnected.

4. To reduce the risk of electrical shock, disconnect AC and DC power
from the inverter before working on any circuits connected to the
inverter. Turning off controls will not reduce this risk.

5. Do not expose the inverter to rain, snow, spray, or bilge water.

6. To reduce the risk of overheating or fire, do not obstruct the
ventilation openings, and do not install the inverter in a zero­clearance compartment.

Explosive Gas Precautions

1. Batteries generate explosive gases during normal operation. Be sure
you read this guide and all battery documentation and follow all
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

vii

Important Safety Information

locations that require ignition-protected equipment. These locations
include 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 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 metal items like rings, bracelets, and watches when
working with lead-acid batteries. Lead-acid 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

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 1000 can power this charger or adapter safely.

Some chargers for small nickel-cadmium batteries can be damaged if
connected to the Prowatt 1000. Do not use the following with the

Prowatt 1000:

• 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.

Superior features and rugged durability have been combined with extreme
ease of use:

• The unit is compact, light weight, and easy to install.

• You can power loads directly from the dual GFCI receptacles on the

front panel, or you can hardwire the unit into an existing AC electrical
system using the built-in terminal blocks.

• Easy-to-read indicators on the front panel let you monitor system
performance at a glance.

• The remote On/Off switch lets you control the inverter from a
convenient location—up to 20 feet (6 m) away—while the inverter
itself is mounted out of sight and close to the batteries.

Comprehensive Protection

The Prowatt 1000 is equipped with numerous protection features to
guarantee safe and trouble-free operation:

Low battery alarm Alerts you if the battery has become discharged to

10.7 V or lower.

Low voltage shutdown Automatically shuts the inverter down if the battery voltage drops below 10 V. This feature protects the battery from being completely discharged.

High voltage shutdown Shuts the inverter down automatically if the input voltage rises to 15 V or more.

Overload shutdown Shuts the unit down automatically if a short circuit occurs or if the loads attached to the inverter exceed the operating limits.

Over temperature shutdown Turns the inverter off if its temperature rises above an acceptable level.

GFCI protection De-energizes the AC circuits and thereby protects the user from electric shock if a ground fault occurs.

Designing Your Installation

Before doing anything else, you need to determine how you are going to
use your PROwatt 1000, and on the basis of that, design a power system
that will give you maximum 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 battery size strongly affect the performance of the
PROwatt 1000. Therefore, you need to identify the type of loads your
inverter will be powering and how much you will be using them between
charges. 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” for a detailed explanation
of how to determine the appropriate number and size of batteries for your
needs.

CAUTION

The PROwatt 1000 must only be connected to a battery that has
a nominal output of 12 volts. It will not operate if connected to a
6 volt battery and will be damaged if connected to a 24 volt
battery.

Choosing a Charging System

The charging system must be appropriate for your particular installation.
A well-designed charging system 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” for information
about designing an effective charging system.

Choosing a Location

WARNING

The PROwatt 1000 contains components that 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.

WARNING

To reduce the risk of fire, do not cover or obstruct the
ventilation openings. Do not install the PROwatt 1000 in a zero­clearance compartment. Overheating may result.

The Prowatt 1000 must only be installed in a location that is:

Choosing a Location

Dry

Cool

Ve nt il at e d

Safe

Close to

gases

Do not allow water or other liquids to drop or splash on the
inverter.

Ambient air temperature should be between 32º F and
105º F (0º C and 40º C)—the cooler the better within this
range.

Allow at least 2 inches (5 cm) of clearance around the
inverter for air flow. Ensure that ventilation openings on the
DC end and the bottom of the unit 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.

Do not use excessive DC cable lengths: they increase wire
resistance and reduce input power. Longer AC wires are
preferable to longer DC wires: wire resistance (and
therefore voltage drop) is less and the cost is lower.

Do not mount the inverter where it will be exposed to gases
produced by the batteries. These gases are very corrosive,
and prolonged exposure will damage the inverter.

3–5

Installation

Connecting to an Existing AC Circuit

You can plug loads directly into the AC receptacle on the front panel of
the PROwatt 1000. You can also connect the inverter to an existing AC
circuit and then plug loads into the receptacles connected to that circuit.

AC Wiring Precautions

If you are going to connect the inverter to existing AC wiring, observe the
following precautions when installing and operating the inverter.

Maintain correct wiring polarity.

A modern 115 volt AC wiring system has three color-coded conductors:

• black = line (“hot”)

• white = neutral (“common”)

• green or bare = ground

Screws on terminals are typically color-coded as follows:

• brass = line

• silver = neutral

• green = ground

3–6

Do not connect the PROwatt 1000 and another AC source (such as a
generator or utility power) to the AC wiring at the same time.

The PROwatt 1000 will not operate if its output is connected to AC
voltage from another source, and potentially hazardous or damaging
conditions may occur. These conditions can occur even if the inverter is
switched off.

If you install the Prowatt 1000 into an electrical system that also uses
power from a generator or a utility line, you must include a switch that
prevents the inverter and the other power source from being connected to
the AC distribution system at the same time. See “Installing Transfer

Switches in AC Circuits” on page 3–8.

Do not connect the PROwatt 1000 to an AC branch circuit that has
high-power consumption loads.

The PROwatt 1000 will not operate electric heaters, air conditioners,
stoves, and other electrical appliances that consume more than 1000
watts.

AC Wiring Procedure

To make a permanent connection to existing AC wiring:

1. Make sure no DC voltage is being supplied to the inverter, and make
sure no AC voltage is present on the AC wiring.

2. Remove the bottom plate from the inverter. This gives you access to the
AC terminal blocks. See Figure 3-1.

3. Remove the knockout on the DC end of the inverter.

4. Feed 3-conductor 14 AWG AC cable through the hole.

5. Insert a cable clamp for electrical junction boxes to hold the cable in place.

6. Connect the ground lead of the AC cable (green or bare wire) to the
internal terminal block labelled
ground lead to a grounding point on a junction box or breaker panel.
Make sure the ground lead is cut as short as possible and is not touching
any component within the inverter.

7. Strip 1/4 inch (6 mm) of insulation from the line (black) and neutral
(white) leads, and connect them to the AC output terminal blocks on the
PROwatt 1000 circuit board. These terminal blocks are labeled
and

CAUTION: Reverse Polarity

Improper connections (connecting a line conductor to a

to malfunction and may permanently damage the inverter.

Damage caused by a reverse polarity connection is not
covered by your warranty.

Ensure that you have maintained correct polarity and that there are no
loose strands of wire.

Installing Transfer Switches in AC Circuits

If you are using another AC source on the same circuit as the
PROwatt 1000, install a transfer switch to ensure that the sources never
power the circuit at the same time.

The switching mechanism can be as simple as a plug that you insert in the
desired AC power source. See Figure 3-2.

You can also use a manual or automatic transfer switch. See Figure 3-3. A
transfer switch is a double pole, double throw (DPDT) switch that switches

3–8

both the line and neutral wires to the AC distribution system from one
power source to the other. They are commonly used to switch between a
generator and utility power (shorepower).

Figure 3-2 Simple Transfer Switching

Connecting to an Existing AC Circuit

Figure 3-3 Automatic Transfer Switch

Manual and automatic transfer switches are available from marine and RV
dealers. Make sure you buy an approved switch with AC voltage and current
ratings that exceed the output ratings of both the inverter and the other
power source.

Installation

Installing the Remote On/Off Switch

The remote switch lets you turn the Prowatt 1000 on and off from a
convenient location—up to 20 feet (6 m) away from the inverter—while the
inverter is mounted out of sight and close to the batteries.

To install the remote

1. Cut out the template printed on page D–5 and position it on the wall
where you want to install the switch.

The switch requires a minimum of 0.7 inches (18 mm) of clear depth.

2. Mark the location of the two screw holes and the area to be cut out.

3. Pilot drill the two screw holes.

4. Cut out the square area.

5. Feed the communications cable and connector through the cut-out hole
in the panel, and route the cable to the jack on the bottom of the inverter.

6. Plug the connector into the jack on the bottom of the inverter.

7. Fasten the switch assembly using the two screws that are provided.

If you need more cable than the 20 feet (6 m) supplied, buy a 1:1 connector
and a high-quality 4-conductor, telephone extension cable with an RJ-11
conductor on each end.

You can use a total cable length of 100 feet (30.5 m) although 50 feet
(15.25 m) is the maximum recommended.

Mounting the Inverter

To mount the Prowatt 1000:

1. Turn off the inverter’s On/Off switch.

2. Select an appropriate mounting location and orientation. The inverter
must be oriented in one of the following ways:

• Horizontally on a vertical surface. (The ventilation openings on the DC
end must not point up or down.)

• On or under a horizontal surface

3. Hold the inverter against the mounting surface, mark the positions of the
mounting screws, and then remove the inverter.

4. Pilot-drill the four mounting holes.

5. Fasten the inverter to the mounting surface using corrosion-resistant
hardware sized #10 or larger.

Connecting the Chassis Ground

WARNING: Electrical Shock Hazard

Never operate the PROwatt 1000 without connecting it to the
ground. Electrical shock hazard could result.

The PROwatt 1000 has a screw terminal labeled CHASSIS GND on the
outside of the rear panel as shown in Figure 3-4. Follow the guidelines in

“Grounding Locations” to connect the inverter’s chassis to the ground.

Connecting the Chassis Ground

Figure 3-4 Rear Panel Connections

The neutral (common) conductor of the inverter AC output circuit is
connected to the chassis ground. Therefore, when the chassis is connected to
ground, the neutral conductor is also grounded. This conforms to National
Electrical Code requirements stating that separately derived AC sources
(such as inverters and generators) must have their neutral conductors tied to
the ground in the same way that the neutral conductor from the utility line is
tied to the ground at the AC breaker panel.

Grounding Locations

The chassis ground terminal must be connected to a grounding point. The
grounding point varies depending on where you install the PROwatt 1000.
Follow the guidelines that correspond to your type of installation:

Installation

Marine Connect the or the engine’s negative bus using 6 AWG copper wire that is bare or has insulation rated at 90º C.

Fixed Location (residential, for example) Connect the screw to your system’s DC grounding point using 6 AWG wire. The system’s grounding point is usually the AC service entrance grounding point or a separate ground rod. For a solar PV (photovoltaic) installation, this is usually the same rod used to ground the PV array.

Connecting DC Cables

To operate safely and effectively, the PROwatt 1000 needs proper cables,
wiring, and fuses. Because the PROwatt 1000 has 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

Follow these guidelines and refer to Table 3-1 to plan the DC cabling:

• Use 4 AWG copper (90º C insulation rating) as the smallest DC cable
size. This will minimize the voltage drop between the battery and the
inverter. If the cables cause an excessive voltage drop, the inverter may
shut down when drawing higher currents because the voltage at the
inverter input drops below 10 volts.

• Keep all cables as short as possible, and ensure that each cable between
the inverter and the battery is no longer than 4 feet (1.2 m).

• If you must use longer cables, choose a larger diameter cable such as
2 AWG, and use appropriate crimp connectors.

• Do not use aluminum. It has about 1/3 more resistance than copper cable
of the same size, and it is difficult to make good, low-resistance
connections to aluminum wire.

Table 3-1 Recommended Wire Sizes and Lengths

Wire Size

Fuse/Circuit Breaker Sizing Guidelines

Because your batteries can produce thousands of amps, you need fuses or
circuit breakers that can safely withstand the short-circuit current they can
produce.

To select the correct fuse type and size:

1. Determine the total cold cranking amp rating for your battery(s). (The

cold cranking amp rating of each battery is displayed on the battery
case. If it is not, contact the battery manufacturer.) For example:

•If you are using one battery to power your inverter and its rating is 500,
the total cold cranking amp rating is 500.

•If you are powering your inverter with two batteries, and each has a
rating of 500, the total cold cranking amp rating is 1000.

2. Once you have determined the total cold cranking amp rating of your
batteries, identify the corresponding Ampere Interrupting Capacity
(AIC) of the fuse or breaker required for your system by referring to

Table 3-2. (The AIC is the amount of battery short-circuit amperage that

the fuse can safely withstand.)

•If the Total Cold Cranking Amps indicate that the AIC is 2,700 amps or

less, choose an ANL 150 fuse.

•If the Total Cold Cranking Amps indicate that the AIC is up to 20,000

amps or if you require a “code fuse”, choose a Class T 150 A fuse.

To connect the DC cables:

1. Cut the cables to the correct length.

2. Strip the appropriate amount of insulation off 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.

If you are using crimp connectors, use the tool recommended by the
terminal manufacturer. Make sure no stray wires protrude from the
terminal. (You may find it more convenient to have the crimp
connectors attached by the company that sells you the cable.)

3. Strip about 1/2 inch (1.25 cm) from the ends of the cables that will be
connected to the inverter.

3–15

Installation

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, be rated for DC circuits, and have an Ampere
Interrupting Capacity (AIC) that exceeds the short-circuit current
available from the battery. (See “Fuse/Circuit Breaker Sizing

Guidelines” on page 3–13.)

5. Insert the stripped ends of the cables into the cabling terminals on the
DC end of the inverter and tighten the screws securely. The red
terminal is positive (+); the black terminal is negative (–). See

Figure 3-4.

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 1000 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 permanently damage the unit.
Damage caused by a reverse polarity connection is not
covered by your warranty.

3–16

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
1000 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 or battery banks.

10. Turn on the inverter’s On/Off switch.

Connecting DC Cables

11. Check the front panel of the inverter. The VOLTS indicator should

read 12–13 volts, depending on the voltage of the battery. If it does

Operation

Turning the Inverter On and Off

The On/Off switch on the inverter’s front panel turns the control circuit in
the PROwatt 1000 on and off.

To turn the inverter on and off from its front panel:

• Turn the inverter’s On/Off switch on or off.

When the switch is Off, the inverter draws no current from the
battery.

CAUTION

The inverter’s On/Off switch does not disconnect power from
the Prowatt 1000.

Operating Several Loads at Once

If you are going to operate several loads from the PROwatt 1000, 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 On/Off 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,
switch the inverter off.

Testing the GFCI-Protected AC Outlet

The AC outlet on the Prowatt 1000 is a Ground Fault Circuit Interrupter
(GFCI) outlet. This protects you against hazardous electrical shocks that
could be caused by dampness, faulty mechanism, worn insulation, etc.
You might still feel shock, but the GFCI should cut it off quickly enough
so an adult in normal health is not seriously injured (infants and small
children may still be affected).

Test the GFCI periodically to make sure it is operating correctly.

To test the GFCI protection:

1. Turn the inverter on.

switch:

2. Plug a test lamp into the outlet.

3. Push the TEST button.

The RESET button should pop out and the power should turn off (the
lamp should go out). If the lamp remains lit, or if the RESET button
does not pop out, return the inverter to the place of purchase for
service.

If the GFCI trips by itself at any time, reset it and perform the preceding
test.

Power Output

The Prowatt 1000 will deliver up to 1000 watts or 8 amps continuously,
depending on input voltage and ambient temperature. The 1000 watt
capability is reached when ambient temperature is less than 68º F (20º C)
and input voltage is between 12 and 13 volts.

The inverter will deliver more than 1000 watts or 8 amps for
approximately 10 to 15 minutes. The inverter must cool for 15 minutes
before it can resume operation above 1000 watts.

Operation

Inverter Loads

The PROwatt 1000 will operate most AC loads within its power rating
(1000 watts / 8 amps). However, some appliances and equipment may be
difficult to operate, and other appliances may actually be damaged if you
try to operate them with the PROwatt 1000. Please read “Problem

Loads”and “Trouble Loads” carefully.

Problem Loads

Some induction motors used in freezers, pumps, and other motor-operated
equipment need high surge currents to start. The PROwatt 1000 may not
be able to start some of these motors even though their rated current draw
is within the inverter’s limits. The PROwatt 1000 will normally start
single-phase induction motors rated at 1/2 horsepower or less.

Trouble Loads

If a motor refuses to start, observe the
trying to start the motor. If the indicator drops below 11 volts while the
Prowatt 1000 is trying to start the motor, this may explain why the motor
won’t start. Make sure the length and diameter of the battery cables are
appropriate. Check that the battery connections are good and that the
battery is fully charged. If the cables are sized correctly, the connections
are good, and the battery is charged, but the voltage still drops below 11
volts, you may need to use a larger battery.

CAUTION

Some equipment may be damaged by the PROwatt 1000’s
quasi-square wave output.

Some appliances, including the types listed below, may be damaged if
they are connected to the PROwatt 1000:

• Electronics that modulate RF (radio frequency) signals on the AC line
will not work and may be damaged.

• Speed controllers found in some fans, kitchen appliances, and other
loads may be damaged.

• Some rechargers for small nickel-cadmium batteries can be damaged.

Common Problems

Buzz in Audio Equipment

Some inexpensive stereo systems emit a buzzing noise from their
loudspeakers when operated from the PROwatt 1000. This occurs because
the power supply in the audio system does not adequately filter the
modified sine wave produced by the inverter. The only solution is to use a
sound system that has a higher quality power supply.

Television Reception

When it is operating, the PROwatt 1000 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 1000 is
solidly connected to the ground system of your vehicle, boat, or
home.

2. Make sure 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 1000 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 1000 as possible.

5. Do not operate high power loads with the Prowatt 1000 while the
television is on.

of battery.

Battery Types and Sizes

Battery Types

Automotive Starting Batteries

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 when
starting 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 recharged. If it is used in this
kind of deep discharge service, it will wear out very rapidly.

Deep-Cycle Lead-Acid Batteries

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.

For most applications of the Prowatt 1000, Xantrex recommends that you
use one or more deep-cycle batteries that are separated from the vehicle’s
starting battery by a battery isolator.

B–2

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 B-1 and Figure B-2 show a battery isolator in
configurations for normal and heavy-duty loads.

Battery isolators are available at marine and RV dealers and most auto
parts stores.

Battery Size

Battery Size

CAUTION

The PROwatt 1000 must only be connected to batteries with a
nominal output voltage of 12 volts. The inverter will not operate from
a 6 volt battery and will be damaged if connected to a 24 volt battery.

Importance Battery size or capacity is as important as the battery type for efficient

operation of your loads. Xantrex recommends that you purchase as much
battery capacity as possible.

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 100 Ah can deliver 5 amps for 20 hours (5 A x 20 hours = 100 Ah).

This same battery can deliver a higher or lower current for less or more
time, limited approximately by the 100 Ah figure (for example, 50 A for 2
hours, or 200 A for 1/2 hour), but usually the capacity figure given is only
accurate at the specified rate (20 hours).

To calculate the battery capacity you require, read “Estimating Battery

Requirements” on page B–4 and “Battery Sizing Example” on page B–4,

and then complete the “Battery Sizing Worksheet” on page B–5.

B–3

Battery Types and Sizes

Estimating Battery Requirements

To determine how much battery capacity you need:

1. Determine how many watts are consumed by each appliance that you
will operate from the PROwatt 1000. 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.

Battery Sizing Example

This battery sizing example illustrates a typical calculation, assuming an
opportunity to charge the batteries every three days.

(= A x B)

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 by re-charging 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.

Use the following worksheet to calculate your battery needs. To ensure
sufficient battery capacity, be generous when estimating the operating
time per day for each of the loads you will run.

Battery Types and Sizes

Using Multiple Batteries

As your power requirements increase, you may need to use more than one
battery to obtain sufficient capacity. Read “Two Batteries Connected In

Parallel” and “Two Separate Battery Banks” to determine whether two

batteries or two battery banks are more appropriate for your applications.

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.

Both Figure B-1 and Figure B-2 show batteries connected in parallel.

Figure B-1 shows a battery configuration suitable for normal loads;
Figure B-2 shows a configuration that is recommended for heavy loads.

CAUTION

Do not connect the following in parallel: batteries made by
different manufacturers, different types of batteries, batteries
that have different Ah ratings. Decreased battery life and
improper charging will result.

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. You should consider temperature when designing 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 temperatures shorten
battery life and therefore you should ventilate the enclosure and use
shade and insulation as appropriate.

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.

B–8

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 Tips

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

12.7–13.0 100%

12.5–12.6 80%

12.3–12.4 60%

12.1–12.2 40%

11.9–12.0 20%

provides guidelines for recharging

Alternators and Charging Systems

Charging System Requirements

Your charging system should be capable of delivering a charging current
equal to 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 1000 directly from an alternator. To
work properly, the inverter must be connected to a battery or a
well-regulated, high-current DC power supply.

Charging With an Engine Alternator

Read the following information to 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 a Standard Vehicle Alternator

A typical engine alternator (12 volts) may not be able to meet the
requirements outlined above 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 amps only deliver a maximum of 30–80 amps in actual use and
deliver even less as battery voltage rises. Many alternators cannot
produce more than 13.6 volts 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 high­output alternator.

C–2

Using an Alternator Controller

If your regular alternator is inadequate by itself, you can install an
alternator controller that bypasses the voltage regulator and boosts 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 100–140 A 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 C–2. For information about

battery chargers, visit our web site at www.xantrex.com

Charging From AC Power

Do not use chargers intended for occasional recharging of automotive
starting batteries. These chargers are not intended for continuous use.

Charging From Alternative Energy Sources

You can also charge your batteries 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

Never operate the Prowatt 1000 directly from an energy source
such as a solar panel. The inverter must be connected to a
battery or a well-regulated, high-current DC power supply to
work properly.
