Safety

Explosive gas precautions

WARNING: Explosion hazard

1. Working in the vicinity of lead-acid batteries is dangerous. Batteries
generate explosive gases during normal operation. Therefore, you
must read this guide and follow the instructions exactly before
installing or using your XPower Inverter 3000 Plus.

2. This equipment contains components which tend to produce arcs or
sparks. To prevent fire or explosion, do not install the XPower
Inverter 3000 Plus 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.

3. 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 or dropping a metal tool on the battery.
It could spark or short circuit the battery or other electrical parts and
could cause an explosion.

vi 975-0128-01-01

Safety

5. Remove all 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 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 lead-acid 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.

10. If you need to remove a battery, always remove the ground terminal

from the battery first. Make sure all accessories ar off so you don’t
cause a spark.

Precautions for Using Rechargeable Appliances

CAUTION: Equipment damage

Most rechargeable battery-operated equipment uses a separate charger or
transformer that is plugged into an AC receptacle and produces a low
voltage charging output.

Some chargers for small rechargeable batteries can be damaged if
connected to the XPower Inverter 3000 Plus. Do not use the following
with the XPower Inverter 3000 Plus:

• Small battery-operated appliances like flashlights, razors, and night

lights that can be plugged directly into an AC receptacle to recharge.

• Some chargers for battery packs used in power hand tools. These

3 Installation

Chapter 3, “Installation,” provides information on cables and fuses to help
you plan for your installation and provide procedures for installing the
inverter.

Read the entire chapter before beginning the installation procedures so
that you can plan an installation that is suited to your power needs.

Designing Your Installation

Before doing anything else, you need to determine how you are going to
use your inverter, and then 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 will need to:

• Be aware of installation codes

• Calculate your battery requirements

• Choose an effective charging system

• Choose an appropriate location

• Calculate the cable size for your inverter

• Select the correct fuses or circuit breakers

Study Figures “Configuration for Normal Loads” on page 3–2 and
“Configuration for Heavy Loads” on page 3–2 for an example of a setup
for normal or heavy loads in a vehicle. When you have decided upon your
configuration, then you can calculate battery requirements.

3–1

Configuration for Heavy Loads

Installation Codes

Governing installation codes vary depending on the location and type of
installation. Electrical installations must meet local and national wiring
codes and should be performed by a qualified electrician.

In residential applications, electrical codes do not allow permanent
connection of AC distribution wiring to the inverter’s AC output
receptacles. The receptacles are intended for temporary (as-needed)
connection of cord connected loads only.

Calculating Battery Requirements

Battery type and battery size strongly affect the performance of the
inverter. 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. We recommend that you purchase
as much battery capacity as possible.

Consult Appendix B for a detailed explanation of how to determine the
appropriate number and size of batteries for your needs.

Designing Your Installation

CAUTION

The inverter must only be connected to a 12 V battery system. It will not operate
if connected to a 6 V battery and will be damaged if connected to a 24 V battery.

Choosing an Effective 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 choosing an effective charging system.

975-0128-01-01 3–3

Installation

Choosing an Appropriate Location

WARNING

The inverter 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 inverter in a zero-clearance compartment. Overheating may result.

:

The inverter must only be installed in a location that is:

Dry Do not allow water or other liquids to drop or splash on it.

Cool Ambient air temperature should be between 0 and 40ºC

(32 and 105ºF)—the cooler the better within this range.

Ventilated Allow at least 3" (76 mm) of clearance around the inverter

for air flow. Ensure that the ventilation openings on the DC
end and on the bottom of the inverter are not obstructed.

Safe 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

Protected
from battery
gases

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 batteries. Battery gases are corrosive, and
prolonged exposure to battery gases will damage the
inverter.

3–4 975-0128-01-01

Calculating Cable Sizes

To operate safely and effectively, the XPower Inverter 3000 Plus needs
proper cables and fuses. Because the XPower Inverter 3000 Plus has low­voltage and high-current input, it is essential that you use low-resistance
wiring between the battery and the inverter to deliver the maximum
amount of usable energy to your load.

For safe and efficient operation, you will need to calculate cable sizes for
your:

• DC input cables from the battery to inverter (one way)

• Chassis ground cable from the grounding point to the chassis ground

lug on the inverter’s DC panel.

See Figure 3-4, “DC Panel Connections” on page 3–11.

WARNING

Use only copper wire rated 90 °C minimum. Never use a DC input cable longer
than specified in Table 3-1. A longer cable can potentially generate enough heat
to start a fire or result in poor inverter performance.

Designing Your Installation

Calculating Size of DC Input Cables

Refer to Table 3-1 to plan the DC cabling:

• Keep all cables as short as possible, and ensure that each cable

between the inverter and the battery is no longer than 10 feet (3 m).

• Do not use aluminum cable. It has about 1/3 more resistance than

copper cable of the same size, and it is difficult to make good, low­resistance connections to aluminum wire.

• We recommend that you use oil-resistant cable.

Calculating Fuse/Circuit Breaker Size

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

To select the correct fuse type and size:

1. Determine the total short-circuit current rating for your batteries. For

example:

• If you are using one battery to power your inverter and its short­circuit current rating is 500 A, the total short-circuit current rating
is 500 A.

• If you are powering your inverter with two 12 V batteries
connected in parallel, and each battery has a short-circuit current
rating of 500 A, the total short-circuit current rating is 1000 A.

• If you are powering your inverter with two 6 V batteries
connected in series, and each battery has a short-circuit current
rating of 500 A, the total short-circuit current rating is 500 A.

Designing Your Installation

Important:

rating is the sum of the short-circuit current ratings of all of the batteries
connected in parallel. For batteries connected in series, the total short-circuit
current rating is equal to the short-circuit rating of a single battery.

For batteries connected in parallel, the total short-circuit current

2. Once you have determined the total short-circuit current rating of
your batteries, pick the fuse/circuit breaker’s interrupt capacity based
on the short-circuit current calculated in step 1.

3. Choose a fuse/circuit breaker with a correct current rating.

Fuses can be bought at any marine supply store, RV supply store, or
electrical products store.

4. Connect the chassis ground.

5. Connect the DC cables.

Installing the Remote On/Off Switch

The Remote On/Off switch can be plugged into the remote switch jack on
the front of the inverter. The remote switch lets you turn the inverter on
and off from a convenient location—up to 20 feet (6 m) away from the
inverter.

975-0128-01-01 3–9

Installation

Mounting the Inverter

Do not mount the inverter under the hood of your vehicle. See “Choosing
an Appropriate Location” on page 3–4.

To mount the inverter:

1. Make sure the On/Off switch is in the Off position.

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

• Horizontally on a vertical surface. (Do not mount with the fan

• On a horizontal surface.

• Under a horizontal surface.

pointing up or down.)

Figure 3-3

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
fasteners sized #10 or larger.

3–10 975-0128-01-01

Approved Mounting Orientations

AC Connections

You can plug your AC loads directly into the receptacles on the inverter
front panel. Output power to each receptacle is limited by a circuit
breaker to 1500 Watts (15 A).

You may also make a permanent AC connection via the AC knockout.
This connection must be made in accordance with applicable electrical
codes. If you are not familiar with the applicable electrical codes and
wiring practices, we recommend you have the inverter installed by a
qualified electrician.

Connecting the Chassis Ground

The inverter has a lug connector labelled CHASSIS GND on the rear panel
as shown in Figure 3-4. This lug is used to connect the chassis of the
inverter to your system’s DC grounding point as required by regulations
for some installations. Follow the guidelines in “Grounding Locations” to
connect the inverter’s chassis to the ground.

Use copper wire that is provided with green insulation. Do not use the DC
Ground Lug for your AC grounding.

Installation

WARNING: Electrical Shock Hazard

Never operate the inverter without properly connecting the chassis ground. An
electrical shock hazard could result from improper grounding.

Grounding Locations

You must connect the chassis ground terminal to a grounding point.

Follow the installation guidelines below. These guidelines assume you are
using the code-compliant DC supply cable and fuse sizes indicated in this
manual. If you are using different sizes, refer to the applicable code for
DC grounding details.

Recreational Vehicle Use 8 AWG copper wire and connect it between

the Chassis Ground lug and the vehicle’s DC grounding point (usually the
vehicle chassis or a dedicated DC ground bus).

Chassis Ground Lug

To connect the cable to the chassis ground lug:

1. Make sure the inverter’s On/Off switch is in the Off position.

2. Loosen chassis ground lug screw using a screwdriver.

3. Strip 3/8" (9.5 mm) of insulation from one end of the cable.

4. Place one end of the cable into the ground lug.

5. Tighten the chassis ground lug.

DC Disconnects and Over-Current Devices

The DC circuit from the battery to the inverter must be equipped with a
disconnect and over-current device. This usually consists of a circuit
breaker, a “fused-disconnect,” or a separate fuse and DC disconnect. Do
not confuse AC circuit breakers with DC circuit breakers. They are not
interchangeable. The rating of the fuse or breaker must be matched to the
size of cables used in accordance with the applicable installation codes.
The breaker or disconnect switch and fuse should be located as close as
possible to the battery, in the positive cable. Applicable codes may limit
how far the protection can be from the battery.

DC cable lug examples

Consult Figure 3-1, “Configuration for Normal Loads” on page 3–2, or
Figure 3-2, “Configuration for Heavy Loads” on page 3–2 for additional
details that are specific to your installation.

To make the DC connections:

1. Cut the cables to the correct length with enough insulation stripped

off so you can properly install the type of terminals you will be using.

The terminals on the DC end are designed to fit up to 500 MCM
crimp-on ring terminals (either AMP or ILSCO) or box connectors.

2. Attach the connectors to both cables.

If using compression lugs, attach the terminals to both cables using
the crimp tool recommended by the manufacturer of the ring
terminals. There must be no stray wire strands protruding from
the terminal. If using box lugs, attach the lug to the XPower Inverter
3000 Plus first, then insert the wire and tighten the set screw to the
torque recommended by the lug manufacturer.

3. Route the DC supply cables from the battery bank to the inverter.

975-0128-01-01 3–13

Installation

4. Install a fuse and disconnect switch or breaker between the inverter
and the battery. Ensure that the disconnect switch or breaker is turned
off before installing. They must be installed in the positive side of the
DC circuit, as close as possible to the battery. This protects your
battery and wiring in case of accidental shorting. See “Calculating
Fuse/Circuit Breaker Size” on page 3–7.

5. Attach one connector on the positive cable to the positive DC
terminal on the DC end, and then attach the other connector to the
POSITIVE (+) terminal on the fuse or breaker.

CAUTION: Reverse polarity

DC power connections to the inverter 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 inverter. The fuse is not user
replaceable and the inverter may need to be returned for servicing.
Damage caused by a reverse polarity connection is not covered by your warranty.

Observe the polarities carefully while completing the installation. Use
a wrench to tighten to a torque of 216–240 inch-pounds (24–27 Nm).
Test that the cable is secure.

CAUTION

Do not over-tighten the nut on the DC input terminals. Damage to the DC input
terminals may result.

CAUTION

Do not remove the terminal nut.

CAUTION

Loose connections cause excessive voltage drop and may cause overheated wires
and melted insulation.

3–14 975-0128-01-01

Connecting the DC Cables

6. Connect one connector on the negative cable to the negative terminal on
the DC end. Before proceeding, check that cable polarity is correct, and
then connect the other end of the cable to the NEGATIVE (–) terminal
on the battery.

This is the last cable connection you make. If the disconnect switch or
breaker is not turned off, a spark is normal when the connection is made.
Use a wrench to tighten to a torque of 216–240 inch-pounds (24–27
Nm). Test that the cable is secure.

7. Attach the DC terminal covers.

8. Before proceeding, double check that you have connected the cables
properly—positive to positive, negative to negative.

9. Turn on the battery disconnect switch or breaker.

10. If you have installed a battery selector switch, use it to select one of the
batteries or battery banks (house bank preferred over start bank).

11. Move the inverter’s On/Off switch to the On position.

12. Check the input voltage display. It should read between 12 and 13 V,
depending on the condition of the battery. If it does not, check your
battery and the connection to the inverter, and the state of charge of the
battery.

4 Operation

Chapter 4 explains how to operate the inverter efficiently and effectively.
Specifically, this chapter:

• Gives procedures for operating the inverter from the front panel

• Discusses operating limits and inverter loads

• Discusses battery charging frequency

• Provides information about routine maintenance

Turning the Inverter On and Off

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

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

• Move the On/Off switch to the On position to turn the inverter on.

• Move the On/Off switch to the Off position to turn the inverter off.

When the switch is Off, the inverter draws a very low current from
the battery.

CAUTION

The inverter’s On/Off switch does not disconnect DC battery power from the
inverter. You must disconnect AC and DC power before working on any circuits
connected to the inverter.

Operating Several Loads at Once

If you are going to operate several loads from the inverter, turn them on
separately after you have turned the inverter on.

Turning loads on separately helps to ensure that the inverter does not have
to deliver the starting current for all the loads at once, and will help
prevent an overload shutdown.

4–1

Operation

Turning the Inverter Off Between Charges

The inverter draws less than 600 mA from the battery with the On/Off
switch turned on and no load connected, but left in this state the inverter
will eventually discharge the battery.

To prevent unnecessary battery discharge, turn the inverter off when you
are not using it.

975-0128-01-01 4–3

Operation

Inverter Loads

The inverter will operate most AC loads within its power rating of
2500 W. 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 inverter. Please read “High Surge Loads” and
“Trouble Loads” carefully.

High Surge Loads

Some induction motors used in freezers, pumps, and other motor-operated
equipment require high surge currents to start. The inverter may not be
able to start some of these motors even though their rated current draw is
within the inverter’s limits. The inverter will normally start single-phase
induction motors rated at 3/4 horsepower or less.

If a motor refuses to start, observe the
while trying to start the motor. If the indicator drops below 11 V while the
inverter is trying to start the motor, this low voltage condition may be why
the motor won’t start. Make sure that the battery connections are good and
that the battery is fully charged. If the connections are good and the
battery is charged, but the voltage still drops below 11 V, you may need to
use a larger battery.

BATTERY VOLTAGE INDICATOR

Trouble Loads

CAUTION

Some equipment may be damaged by the inverter’s modified sine wave output.

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

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

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

• Some chargers for small rechargeable batteries can be damaged. See
“Precautions for Using Rechargeable Appliances” on page vii for
details.

• Metal halide arc (HMI) lights can be damaged.

If you are unsure about powering any device with the inverter, contact the
manufacturer of the device.

4–4 975-0128-01-01

Routine Maintenance

Minimal maintenance is required to keep your inverter operating properly.
Periodically you should:

• Clean the exterior of the inverter with a damp cloth to prevent the

accumulation of dust and dirt.

• Ensure that the DC cables are secure and fasteners are tight.

• Make sure ventilation openings on the AC and DC panels of the

inverter are not clogged.

Recharging Your Batteries

When possible, recharge your batteries when they are about 50%
discharged or earlier. This gives the batteries a much longer life cycle than
recharging when they are almost completely discharged.

5 Troubleshooting

Chapter 5 will help you identify the source of most problems that can
occur with the inverter.

If you have a problem with the inverter, please review this chapter before
contacting place of purchase.

If you are unable to solve a problem and need to contact place of
purchase, record the information in the form “Information About Your
System” on page WA–6.

Common Problems

Buzz in Audio Equipment

Some inexpensive stereo systems may emit a buzzing noise from their
loudspeakers when operated from the inverter. 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 the inverter is operating, it can interfere with television reception
on some channels. If interference occurs, try the following:

1. Make sure that the chassis ground screw on the rear of the inverter is

solidly connected to the ground system of your vehicle.

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 inverter 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 inverter as possible.

5. Do not operate high power loads with the inverter while the television

is on.

B Battery Types

The information in Appendix B will help you to select, connect, and
maintain batteries that are most appropriate for your application.

The batteries that you use strongly affect the performance of the XPower

3000. It is important to connect the inverter to the correct size and type of
battery.

Battery Types

Automotive Starting Batteries

The lead-acid battery you are most familiar with is probably the starting
battery in your vehicle. 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 the spent capacity is quickly recharged by the
running engine.

The starting battery in your vehicle is not designed for repeated deep­discharge cycles where the battery is almost completely discharged and
then recharged. If a starting battery is used in this kind of deep discharge
service, it will wear out very rapidly.

Deep-Cycle Batteries

Deep-cycle 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 XPower 3000, 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–1

Battery Types

Battery Size

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 3-1, “Configuration for Normal Loads” on
page 3–2 and Figure 3-2, “Configuration for Heavy Loads” on page 3–2
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.

CAUTION

The XPower 3000 must only be connected to batteries with a nominal output
voltage of 12 volts. The XPower 3000 will not operate from a 6 volt battery and
will be damaged if connected to a 24 volt battery.

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.

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

Amp-hour (Ah)
Capacity

B–2 975-0128-01-01

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 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–3 and “Battery Sizing Example” on page B–4,
and then complete the “Battery Sizing Worksheet” on page B–5.

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 XPower 3000. You can normally find the watt
rating labelled 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.

Estimating Battery Requirements

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 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.

Battery Types

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.

Figure 3-1, “Configuration for Normal Loads” on page 3–2 shows a
battery configuration suitable for normal loads.

Figure 3-2, “Configuration for Heavy Loads” on page 3–2 show a battery
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.

Two Separate Battery Banks

If you need more than two batteries (or are using different makes or
models of batteries), Xantrex recommends that you install two separate
battery banks and a battery selector switch.

Figure 3-2, “Configuration for Heavy Loads” on page 3–2 shows two
separate battery banks and a battery selector switch. This configuration is
recommended for heavy-duty applications.

By installing a battery selector switch, you can select between the two
battery banks, use both banks in parallel, or disconnect both banks from
the load. Battery selector switches are available at marine and RV dealers.

with the batteries in your system.

Sensitivity

Discharged
Batteries

Electrolyte
Level

Lead-acid batteries may emit hydrogen gases, 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.

The capacity of lead-acid batteries is temperature sensitive. Battery
capacity is rated at 77 ºF (25 ºC). At 0 ºF (–20 ºC), 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.

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, and they should be recharged periodically even if they are
not being used.

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 only distilled water.

Battery
Connections

Battery State of
Charge

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.

You can measure battery state of charge with a hydrometer or
approximate state of charge with a voltmeter. Use a digital voltmeter that
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 V 100%

12.5–12.6 V 80%

12.3–12.4 V 60%

12.1–12.2 V 40%

11.9–12.0 V 20%

C Alternators and Charging

Systems

A good charging system is important for the health of your batteries. Poor
recharging methods can quickly damage batteries.

Appendix C provides guidelines for recharging batteries from an
alternator, from AC power, and from alternate energy sources.

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 A. The charging system must also be able to charge each 12 V 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 inverter directly from an alternator. To work properly, the
inverter must be connected to a battery or a well-regulated, high-current DC
power supply.

C–1

Alternators and Charging Systems

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 V) 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. When 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 only deliver a maximum of 30–80 A in actual use
and 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 high­output alternator.

Using an Alternator Controller

If your regular alternator is inadequate, 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.

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 auto parts
suppliers.

C–2 975-0128-01-01

Charging From AC Power

Charging From AC Power

When recharging from AC power, use a good quality charger or RV
converter that meets the requirements outlined in “Charging System
Requirements” on page C–1.

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 inverter 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.
