Important Safety Instructions

READ AND SAVE THESE INSTRUCTIONS

The RS2000 Sine Wave Inverter/Charger Installation Guide contains
important safety instructions.

Before you install and use your RS2000 Sine Wave Inverter/Charger, be
sure to read, understand, and save these safety instructions and those in
the other product guides.

Read all cautionary markings on the inverter/charger, the batteries, and all
appropriate sections of this guide.

1. Use of accessories not recommended or sold by Xantrex T echnology,
Inc. may result in a risk of fire, electric shock, or injury to persons.

2. The inverter/charger is designed to be permanently connected to your
AC and DC electrical systems. Xantrex recommends that all wiring
be done by a certified technician or electrician to ensure adherence to
the local and national electrical codes applicable in your application.

3. To avoid a risk of fire and electric shock, make sure that the existing
wiring is in good condition and that the wire is not undersized. Do not
operate the inverter/charger with damaged or substandard wiring.

4. To reduce risk of damage and injury, charge only rechargeable
lead-acid batteries (flooded, gel, or absorbed glass mat (AGM) types).
Other types of batteries may burst causing personal injury and
damage.

WARNING: Risk of injury or loss of life

5. Do not operate the inverter/charger if it has received a sharp blow,
been dropped, or otherwise damaged in any way. If the unit is
damaged, see the Warranty and Product Information section in the

RS2000 Sine Wave Inverter/Charger Operation Guide.

6. Do not disassemble the inverter/charger; it does not contain user
serviceable parts. T ake it to a qualified service person when service or
repair is required. Incorrect reassembly may result in a risk of
electrical shock or fire. Internal capacitors remain charged after all
power is disconnected. For instructions on obtaining service, see the
section in the

RS2000 Sine Wave Inverter/Charger Operation Guide.

7. Do not expose the inverter/charger to rain, snow, or water.

8. To reduce the risk of electric shock, disconnect all sources of AC and
DC power from the Inverter/Charger before attempting any
maintenance or cleaning. Turning off controls will not reduce this
risk.

9. The inverter/charger must be provided with equipment grounding
conductors connected to the AC input ground and chassis ground
terminals.

T o reduce the risk of overheating, keep the ventilation openings clear and
do not install the inverter/charger in a compartment with limited airflow
or inadequate clearances around the unit. Refer to the

RS2000 Sine Wave

Explosive Gas Precautions

1. To reduce the ris k of battery explosion, follow these instructions and
those published by the battery manufacturer and the manufacturer of
any equipment you intend to use in the vicinity of a battery. Review
the cautionary markings on these products and on the engine.

2. This equipment contains components which tend to produce arcs or
sparks. T o prevent fire or explosion, do not install the inverter/charger
in compartments containing batteries or flammable materials or in
locations that require ignition-protected equipment. This includes any
space containing gasoline-power machinery, fuel tanks, as well as
joints, fittings, or other connections between components of the fuel
system.

Personal Precautions When Working With Batteries

1. Someone should be within range of your voice or close enough to
come to your aid when you work near a lead-acid battery.

2. Have plenty of fresh water and soap nearby in case battery acid
contacts your skin, clothing, or eyes.

3. Wear complete eye protection and clothing protection. Avoid
touching your eyes while working near batteries.

4. If battery acid contacts your skin or clothing, wash immediately with
soap and water. If acid enters your eye, immediately flood the eye
with running cold water for at least ten minutes and get medical
attention immediately.

5. Never smoke or allow a spark or flame in the vicinity of the battery or
engine.

6. Be extra cautious to reduce the risk of dropping a metal tool onto a
battery. It might spark or short-circuit the battery or other electrical
parts that may cause an explosion.

WARNING: Risk of explosive gases

Working in the vicinity of a lead-acid battery is dangerous. Batteries generate
explosive gases during normal battery operation. For this reason, it is of utmost
importance that each time before servicing equipment in the vicinity of the
battery, you must read this guide and follow the instructions closely.

Safety

viii 975-0126-01-01

7. Remove personal metal items such as rings, bracelets, necklaces, and
watches when working with a lead-acid battery. A lead- acid battery
can produce a short-circuit current high enough to weld a ring or the
like to metal, causing a severe burn.

8. Never charge a frozen battery.

9. If it is necessary to remove a battery, always remove the grounded
terminal from the battery first. Make sure all the accessories are off,
so as not to cause an arc.

10. Be sure the area around the battery is well ventilated.

11. Clean the battery terminals. Be careful to keep corrosion from coming
in contact with your eyes.

12. Study all battery manufacturer’s specific precautions such as
removing or not removing the cell caps while charging and the
recommended rates of charge.

13. For refillable (flooded) batteries, add distilled water in each cell until
the battery acid reaches the level specified by the battery
manufacturer. This helps to purge excessive gas from cells. Do not
overfill. Carefully follow the manufacturer’s recharging instructions.

Planning the Installation

This section provides information to help you plan for a basic installation of the
RS2000.

As your system configuration is determined, record the details in Information
About Your System on page WA-4 of the

RS2000 Sine Wave Inverter/Charger

Operation Guide

.

Two Key Performance Factors

Two key factors in particular will have a major impact on system performance.

Size and Length of DC Cables

To select the appropriate size and length of DC cables, see “DC Cabling” on
page 11.

The DC cables should be as short as possible and large enough to handle the
required current, in accordance with the electrical codes or regulations applicable
to your installation. If there are long battery cables which are in excess of 10 feet
each (10 feet for the positive cable and 10 feet for the negative cable) and not of
sufficient size, the voltage drop across the cables will have a negative impact on
overall system performance.

Mounting Location of the RS2000

To choose an appropriate location for mounting the inverter/charger, see
“Step 1: Choosing a Location for the Inverter/Charger” on page 17.

components of the power system. The AC and DC components are described in
this section and illustrated in Figure 2, “Typical Recreational Vehicle Electrical
System” on page 7.

AC components include:

• Sources of AC input

•AC wiring

• Over-current protection and disconnect devices

• AC distribution panels

DC components include:

• Sources of DC power

• DC cables

• DC over-current protection and disconnect devices

Network considerations include:

• Cables, connectors, network connectors, and terminators for the System
Control Panel and Automatic Generator Start, if installing. See Figure 1.

Detailed information on planning and installing your network is available in
the

Xanbus System Installation Guide. Refer to the system guide to determine

the type of network layout to install, as well as guidelines for installing the

AC Components

AC Input

A source of 120 volts AC single-phase, 60 Hz alternating current is needed to
provide energy for charging batteries and to pass through to AC loads. AC input
can be supplied from an AC source like the utility grid (power company), from a
generator, or from the output of a transfer switch. These sources must have their
neutral conductors bonded to ground. See “AC Output Neutral Bonding” on
page 9.

Disconnect and Over-Current Protection Device

T o meet CSA, UL, and electrical code requirements, the AC inputs and outputs of
the inverter/charger must be provided with over-current protection such as a
circuit breaker or fuse and a disconnect device on both the AC input and output.
Refer to your applicable installation codes and the following requirements:

AC Input Protection

The circuit breaker or fuse used to protect the RS2000 must be rated no more than
30 amps and must be approved for use on 120 VAC branch circuits. If the AC
input power rating is more than 30 amps, you need to add an additional 30 amp
breaker or fuse at the electrical panel to which the RS2000 AC input is wired.

AC Output

The circuit breaker or fuse must be rated at no more than 30 amps and must be
approved for use on 120 VAC branch circuits.

GFCI Requirements

A GFCI (ground fault circuit interrupter) is a device that deenergizes a circuit
when a current to ground exceeds a specified value that is less than that required
to blow the circuit breaker. GFCIs are intended to protect people from electric
shocks and are usually required in wet or damp locations.

Installation in recreational vehicles requires GFCI protection of certain branch
circuits. Consult all applicable codes.

Tested GFCIs

Compliance with UL standards requires that Xantrex test and recommend specific
GFCIs for use on the output of the inverter. Table 1 lists models that have been
tested and will function properly when connected to the AC output of the RS2000.

975-0126-01-01 9

Disconnect Devices

Each system requires a method of disconnecting the AC circuits. If the over­current protection device is a circuit breaker, it will also serve as the disconnect. If
fuses are used, separate AC disconnect switches will be needed ahead of the fuses.

Distribution Panels

Some systems incorporate distribution panels both ahead of the inverter/charger
(the AC source panel) and between the inverter/charger and the loads (the AC
load panel). AC source panel includes a main circuit breaker, which serves as
over-current protection for the panel. Additional circuit breakers serve individual
circuits, one of which serves the inverter/charger.

AC Wiring

Definition AC wiring includes all of the wires and connector s between the AC source an d the

inverter/charger input and all of the output wiring between the inverter/charger
and the AC load panels, circuit breakers, and loads.

Type The type of wiring required varies according to the electrical codes or regulations

applicable to your installation. For RV applications, this may be solid wire in
multi-conductor cables, but stranded wire is required if single conductors are
used. All wiring must be rated 90 °C or higher.

Size Wire size has to be coordinated with the overcurrent protection provided ahead of

the wire involved, in accordance with the electrical codes or regulations
applicable to your installation. The wiring used between the AC input circuit
breaker and the inverter/charger input must be sized to match the input breaker
rating. The wiring used between the AC output of the inverter/charger and the AC
output breaker must also be sized to match the input breaker rating. The wiring
used between the AC output breaker and your loads must be size d to match the
output breaker. Typically, No. 10 AWG is required for the 30A breakers required
to be on the RS2000 input and output.

AC Output Neutral Bonding

Bonding system The RS2000 provides a system that automatically connects the neutral conductor

of the inverter’s AC output circuit to safety ground (“bonding” it) during inverter
operation, and disconnects it (“unbonding” it) when the inverter/charger is
connected to external AC or generator power . Th is system is design ed t o confo rm
to installation codes that require single-phase AC sources such as inverters and
generators to have their neutral conductors tied to ground at the source of power in

Leviton 8599-GY
Pass & Seymour 1594-W

Table 1

Tested G FCI Models

Manufacturer Model Number

Installation

10 975-0126-01-01

the same way that the neutral conductor from the utility is tied to ground. These
same codes specify that the neutral can only be connected to ground in one place
at any one time.

Suitability This automatic neutral-to-ground bonding system is suited for installations in

which the AC input source is known to have a bonded neutral. This will be the
case in most situations: in a utility feed, at an external AC hook-up, or a generator
with a bonded neutral. If not, have an electrician look into bonding the source’s
neutral to ground. See also “AC Input and Output Isolation” on page 21.

Installation

975-0126-01-01 11

DC Components

Batteries

The RS2000 system requires a 12 volt, lead-acid deep-cycle battery or group of
batteries to provide the DC current that the inverter/charger converts to AC power .
The battery may be a flooded, gel, or AGM type.

For general information about batteries, see “Battery Information” on page 39.
For detailed information about specific brands of batteries, you’ll need to consult

individual battery manufacturers for this information.

DC Disconnects and Over-Current Device

The DC circuit from the battery to the inverter/charger must be equipped with a
disconnect and over-current device. (Refer to your applicable installation code.)
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 fuse and disconnect 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 Cabling

DC cabling includes all of the cables and connectors between the batteries, the DC
disconnect and over-current protection device, and the inverter/charge r . All
installations require multi-strand insulated cables as well as disconnect and over­current devices. DC cable sizes are indicated by AWG notation. Under the AWG
standard, a larger gauge number indicates a smaller size diameter. Wire size is
usually marked on the cables for sizes this large.

See T able 2 for required DC cable size and required fuse size for the RS2000.

The

DC cables must be copper and must be rated 90 °C minimum.

Important:

Avoid excessive cable lengths to ensure optimum system

performance.

Installing the Inverter/Charger

Overview

This section provides detailed information on installing the RS2000. The overall
procedure is divided into eight steps:

1. Choosing a location

2. Mounting the inverter/charger

3. Connecting the AC input wires and AC output wires

4. Connecting the DC cables

5. Connecting the battery temperature sensor

6. Connecting to the network

7. Performing checks prior to initial start-up

8. Testing your installation

Installation

975-0126-01-01 17

Step 1: Choosing a Location for the Inverter/Charger

The location of the inverter/charger is a key factor in system performance.
Allow sufficient clearance around the unit and install in a well-ventilated
compartment to prevent overheating and premature shutdown of the inverter/
charger.

The inverter should only be installed in a location that meets the following
requirements:

WARNING: Risk of fire or explosion

This equipment contains components that could produce arcs or sparks. To reduce the risk
of fire or explosion, do not install this equipment 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, or joints, fittings,
or other connections between components of the fuel system.

WARNING: Fire hazard

Do not cover or obstruct the ventilation openings. Do not install this equipment in a
compartment with limited airflow. Overheating may result.

Ventilated Do not operate the inverter/charger in a closed-in area or

restrict ventilation in any way. The inverter/char ger requires
air circulation to maintain optimum operating temperature
and provide best performance. If the unit has inadequate
ventilation, it may shut down due to overheating.
The air vented through the openings should also have a path
to circulate away from the inverter/charger.

Dry Do not allow water or other fluids to drip or splash on the

inverter. Do not expose to rain, snow or water.

Cool Normal air temperature should be between 32 °F and

122 °F (0 °C and 50 °C – the cooler the better within this
range.)

Clearance Allow as much space around the inverter/charger as

possible. Xantrex recommends that other objects and
surfaces be at least 3 inches (76 mm) away from the
ventilation openings for best performance.

Safe Locate the inverter/charger away from battery in a separate

well ventilated compartment. Do not install the inverter/
charger in any compartment containing flammable gases or
liquids like gasoline.

Installation

18 975-0126-01-01

Close to
battery
compartment

The length and size of your DC cables will affect
performance. Use the DC cables recommended in Table 2
on page 11. The unit should not be installed in the battery
compartment due to the possible presence of explosive
hydrogen gas from the batteries.

Protected
from battery
acid and gases

Never place the inverter/charger directly above the
batteries—gases from battery will corrode and damage the
inverter/charger. Never allow battery acid to drip on the
inverter/charger or its wiring when filling the batteries or
reading their specific gravity.

Orientation To meet regulatory requirements, the RS2000 must be

mounted in an approved mounting orientation. See Figure 4
on page 20.

Installation

975-0126-01-01 19

Step 2: Mounting the Inverter/Charger

Considerations

Before mounting the RS2000, take the following two factors into account.

1. The weight of the inverter/charger requires two people to install it.

2. Mounting considerations are shown in Figure 4 on page 20 and described in
Table 3 on page 20.

The RS2000 dimensions and location of the mounting holes are provided in
Figure 15 on page 38.

Mount your inverter/charger before you connect any wires or cables.

To mount the inverter/charger:

1. Remove the inverter/charger from its shipping container.
The inverter/charger is shipped on a packaging board which can also serve as

a template.

2. Remove the four screws that attach the inverter/charger to the packaging
board. Use the box handles provided to move the unit.

3. Verify that all components are present, and record relevant product
information on form WA-4 in the

RS2000 Sine Wave Inverter/Charger

Operation Guide.

4. Select an appropriate mounting location and orientation. To meet regulatory
requirements, the RS2000 must be mounted in one of the six orientations
shown in Figure 4.

5. Use the packaging board as a template to mark the position of the mounting
screws or refer to Figure 15 on page 38.

6. Pilot drill the six mounting holes.

7. Fasten the inverter/charger to the mounting surface with the six ¼"–20 steel
screws or bolts.

WARNING: Heavy load

The RS2000 Sine W ave Inverter/Charger weighs approximately 67 lbs (30 kg). The unit is
too heavy for one person to safely lift and mount. Xantrex recommends that two people
lift and mount the unit. Always use proper lifting techniques during installation to prevent
personal injury.

Important:

Do not use the four screws which attach the unit to the template for
mounting the unit. See “Installation Tools and Materials” on page 15 for recommended
screw size.

Step 3: Connecting the AC Input and AC Output Wires

General AC Wiring Considerations

AC and DC Wiring Separation Do not mix AC and DC wiring in the same

conduit or panel. Consult the applicable installation code for details about DC
wiring and AC wiring in vicinity to each other.

AC Input and Output Isolation The AC input and output circuits of this

inverter/charger are isolated from each other when in invert mode to ensure safe
operation. This isolation must be maintained in the installation, by being sure not
to connect AC input and output wiring to a common point. For example, do not
route the AC input and output neutrals to a common neutral bus.

AC Wiring Compartment For your reference, the AC wiring compartment is

shown in Figure 5.

AC Knockouts There are two 3/4" trade-size knockouts on the front panel for

AC wiring, as shown in Figure 5. For easier wiring access, there are also
knockouts on either side of the unit (not shown). The side knockouts are 1" trade­size knockouts. Use the same trade size of strain relief as the trade size of the
knockout (s) you are using.

AC Wiring Terminals The AC wiring terminals accepts cables of a specific

size. See “Cables for AC output and input wiring” on page 15 for required sizes.

WARNING: Fire, shock, and energy hazards

Make sure wiring is disconnected from all electrical sources before handling. All wiring
must be done in accordance with local and national electrical wiring codes.

Installation

24 975-0126-01-01

Step 4: Connecting the DC Cables

DC Connection Precautions

Connect and disconnect DC wiring only after opening the disconnect switches or
breakers at all AC and DC sources.

Recommended Cable Sizes and Lengths and Fuse Size

For the best load starting surge performance, the DC cables should be as short as
possible and large enough to handle the required current, in accordance with the
electrical codes or regulations applicable to your installation. Avoid excessive
cable lengths.

The DC cables must be copper and must be rated 90 °C

minimum.

For recommended DC cables and fuse size, see Table 2, “Required DC Input
Cable (copper) and Fuse Size” on page 11.

Using a longer or smaller gauge cable

may cause the inverter to shut down under heavy load.

Preparing the Cables

To prepare the DC cables:

1. Cut the negative cable to the required length. Strip off enough insulation so
you can install the terminals you will be using.

Xantrex recommends the use of crimp connectors. The connector should be
designed for a 3/8" stud size to connect to the RS2000. If a crimp connector is
used, it should be crimped using the tool indicated by the connector
manufacturer.

2. Cut the positive cable to the required length. Strip of f enough insulation so
you can install the terminals you will be using.

3. Attach the connectors to the ends of both cables. Make sure no stray wire
strands protrude from the connectors.

Installation

975-0126-01-01 25

Guidelines for Routing the DC Cables

Follow these guidelines to ensure maximum performance.

• Do not attempt to use the chassis in place of the battery negative connection
for grounding. The inverter requires a reliable return path directly to the
battery.

• To reduce the chance of radio frequency interference, keep the positive and
negative cables close together—ideally, held together by straps or loom or
insulated clamps at regular intervals.

• To ensure maximum performance from the inverter, do not route your DC
cables through a DC distribution panel, battery isolator, or other device that
will cause additional voltage drops. The exception is the DC fuse and
Disconnect or the DC circuit breaker which is required at the battery to
protect the DC wiring.

• To help avoid damage caused by reverse polarity battery connection, it is a
good idea to mark each end of each cable to identify it as a positive (red) or
negative (black) cable before routing the wiring.

WARNING: Fire and shock hazard

Route the cables away from sharp edges that might damage the insulation. Avoid sharp
bends in the cable.

Installation

26 975-0126-01-01

Connecting the DC Cables to the Inverter/Charger

To connect the DC cables:

1. Route the DC cables from the battery bank to the inverter/charger. Observe
the “Guidelines for Routing the DC Cables” on page 25.

2. Install a DC fuse and disconnect switch or a DC circuit breaker between the
inverter/charger and the battery. 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
Table 2 on page 11 for required fuse or breaker size. Open the DC disconnect
switch or turn off the DC circuit breaker.

3. Connect one connector on the POSITIVE (+) cable to the POSITIVE DC
terminal on the inverter/charger, as show n in Figure 7. The connector goes on
first, then the flat washer (steel), lock washer (steel), and 3/8" bolt (brass)).

4. Connect the other connector to the POSITIVE (+) terminal on the fuse or
breaker. Observe polarity carefully while completing the installation.

Use a wrench to tighten the bolt to a torque of 15–16 ft-lbs (20.4–21.7 Nm) at
the inverter/charger end. Observe the fuseholder or breaker manufacturer’s
recommendation at the other end.

5. Connect one connector on the NEGATIVE (–) cable to the NEGATIVE (–)
DC terminal on the inverter/charger, as shown in Figure 7. The connector

DC Grounding

The Chassis Ground point on the inverter/charger is used to connect the chassis of
the inverter/charger to your system’ s DC grounding point, as required by
regulations for some installations. Use copper wire that is either bare or provided
with green insulation.

The grounding guideline given below assumes you are using the code-compliant
DC supply cable and fuse sizes indicated in this Installation Guide. If you are
using different sizes, refer to the applicable code for DC grounding detail.

To connect the chassis ground:

1. Using the appropriate screwdriver, loosen the screw on the chassis ground
point shown in Figure 9.

2. Connect a No. 8

AWG copper cable between the chassis ground point and the

DC grounding point for your system.
In an RV or vehicle installation, this will usually be the vehicle chassis or a

dedicated chassis ground bus.

3. Tighten the screw to a torque of 1.0–1.25 ft-lbs (1.47–1.7 Nm).

Step 5: Connecting the Battery Temperature Sensor (BTS)

Installing a battery temperature sensor extends the life of a battery by preventing
overcharging in warm temperatures and undercharging in cold temperatures. W ith
a BTS monitoring the battery temperature, the voltage delivered to the battery is
adjusted according to battery’s actual temperature.

The BTS has a self-adhesive backing and attaches to the side of the battery. A
25-foot (7.6 m) cable is supplied with the BTS, as shown in Figure 10.

Mounting Options

You can mount the battery temperature sensor (BTS) in one of two ways:

• Mounting the sensor to the negative battery post allows the internal battery
temperature to be sensed and provides the most accurate results.

• Attached the sensor to the side of battery using the self-adhesive backing also
provides good results in most situations.

Mounting to the Negative Battery Terminal

To mount the sensor on the negative battery terminal:

See Figure 11.

1. Select the battery to be monitored. The battery temperature sensor should be
connected to the battery bank that is directly connected to the inverter/charger .

2. Switch off all devices operating from the battery, or open battery switch if
present to disconnect battery.

3. Wait 10 minutes for any explosive battery gases to dissipate.

4. Remove the nut that connects existing wiring ring terminals to the battery
negative terminal stud.

5. Move or reorient the existing wiring ring terminals on the battery negative
terminal stud, so there is a flat surface on which to seat the battery
temperature sensor mounting plate.

Y o u may need to bend the ring terminal crimp and/or wires slightly downward
to allow the sensor to seat flush to the top surface of the upper ring terminal.

6. Mount the sensor directly on top of the ring terminal, as shown in Figure 11,
and firmly tighten the terminal nut.

7. Check to ensure that the sensor and all wires are held firmly and cannot be
moved.

8. Turn the battery switch on again (if you opened it in Step 2.)

9. Route the sensor cable to the inverter/charger and plug it into the Battery
Temp jack, as shown in Figure 12. Secure the cable along its length.

Figure 11

BTS Mounted on the Negative Battery Terminal

WARNING: Fire hazard

In this procedure, you must install the DC wire on the battery terminal first. Then the
sensor is installed on top of the DC wire. This sequence is required to provide the best
connection to the battery and to ensure correct performance of the sensor.

Mounting to the Side of the Battery Case

To mount the sensor on the battery case:

See Figure 13.

1. Select the battery to be monitored.
The battery temperature sensor should be connected to the battery bank that is

directly connected to the inverter/charger.

2. Select a side suitable for attaching the sensor.
The surface where the sensor is to be mounted must be flat and free from

reinforcing ribs or other raised features. This surface must be in direct internal
contact with the battery electrolyte. Do not install the sensor near the top of
the battery or on the battery’s top surface.

3. Clean the selected area thoroughly to remove any oil or grease that could
prevent the sensor from adhering to the battery case and allow the battery cas e
to dry thoroughly.

4. Peel the protective backing from the self-adhesive strip on the rear of the
sensor.

5. Press the sensor firmly against the clean side of the battery to fix it in place, as
shown in Figure 13.

6. Route the sensor cable to the inverter/charger and plug it into the Battery
Temp. jack, as shown in Figure 12. Secure the cable along its length.

Step 7: Performing Checks Prior to Initial Start-Up

Before testing your installation, ensure these conditions are met:

❐ Chassis and AC grounds are properly installed.
❐ AC input connections and AC output connections are wired correctly on the

terminal block and not reversed.

❐ Positive (+) battery cable is connected to the positive (+) battery terminal

through the DC fuse and disconnect switch or DC circuit breaker.

❐ Negative (–) battery cable is connected to the negative (–) battery terminal.
❐ Battery voltage is within the proper range for this unit

(10.3–15.3 volts DC).

❐ DC disconnect switch or breaker is turned off.
❐ AC input and output breakers are turned off.
❐ All connections are tight.

Installation

975-0126-01-01 35

Step 8: Testing Your Installation

There are three tests to be performed for testing your installation. The first test
verifies that the RS2000 works in invert mode. The second test verifies that the
RS2000 works in charge mode. The third test verifies that the RS2000 works in
AC bypass mode.

Testing in Invert Mode

To test the inverter/charger in invert mode, using a 100 watt light bulb as the
test load:

1. Close the DC disconnect switch or the DC circuit breaker to supply DC power
to the RS2000.

The unit takes 10 to 30 seconds to initialize. After 10 to 30 seconds, normal
indicator lights illuminate on the front panel.

2. Verify that all lights illuminate. Only the Inverter On light stays illuminated.

3. Close the AC output breaker to connect the RS2000 to the load or load panel.
The light bulb is illuminated.

Testing in Charge Mode

To test the RS2000 in charge mode:

1. Close the AC supply breaker to supply AC power to the unit.

2. After a few seconds, verify that the Bulk light illuminates. Over a period of
time, the Absorption or Float light illuminates as charging progresses.

• In three-stage charging, the Bulk, Absorption and Float lights illuminate

in sequence.

• In two-stage charging, the Bulk and Absorption lights illuminate in

sequence.

WARNING: Shock hazard

The Inverter Enable button on the RS2000 and the optional accessories do not disconnect
DC or AC input power to the RS2000.

Important:

The charging process, whether it is three-stage or two-stage charging,

occurs over an extended period of time.

Installation

Testing in AC Bypass Mode

To test the RS2000 in transfer mode:

1. Close the AC circuit breaker supplying AC input power to the inverter.
The transfer from invert to AC input power occurs.

2. Press the Charger Enable button to disable the charger. Verify that the Charger
Enable light is not illuminated. AC loads will still be powered.

Battery Information

“Battery Information” discusses the physical make-up and characteristics of
chemical storage batteries and will help you to understand the factors involved in
battery selection, charging, care, and maintenance. This information is a guideline
only. The manufacturer of each battery is the best authority on its use and care.

Installation

40 975-0126-01-01

Terminology

A description of battery charger operation requires the use of terms that you may
not be familiar with. The following terms appear throughout the guide.

Deep Cycle A deep cycle occurs when a battery is discharged to less than 50%

of its capacity (50% depth of discharge). A deep-cycle battery is one that is
intended to be deeply discharged and charged repeatedly.

Depth of Discharge (DOD) The amount of energy or charge removed from the

battery bank, usually expressed as a percentage. A depth of discharge of 0%
indicates a fully-charged battery, and a depth of discharge of 100% indicates a
fully-discharged battery.

Electrolyte Typically sulfuric acid and water. It is commonly referred to as

battery acid, and it is the fluid inside a typical lead-acid battery.

Equalization A deliberate overcharge designed to reduce sulfation and

stratification in flooded (or wet) lead-acid batteries. Not necessary and harmful on
Gel or sealed batteries.

Plates Made of lead and connected to the battery terminals. These are the

terminals inside each cell of the battery. The essential chemical reactions of the
battery occur at the plates, and they are the source of the current/voltage produced
by the battery.

Sulfation As a battery discharges, its plates become covered with lead sulfate.

With regular recharging, the lead sulfate leaves the plates and recombines with the
electrolyte. If the lead sulfate remains on the plates for an extended period of time
(over two months), it hardens, and recharging does not remove it. Sulfation
reduces the effective plat e area a nd the bat tery’s capacity. Equa lization of flooded
(or wet) batteries helps to reduce sulfation.

Stratification Over time, electrolyte tends to separate. The electrolyte at the top

of the battery becomes watery while it becomes more acidic at the bottom. This
effect is corrosive to the plates. Equalization of flooded (or wet) batteries helps
reduce stratification.

Temperature Compensation Optimal battery charging voltage is dependent on

the temperature. As the ambient temperature falls, the proper voltage for each
charge stage needs to be increa se d . When the ambient temperature increases, the
proper voltage for each charge stage needs to be decreased. (The RS2000 battery
temperature sensor (BTS) automatically rescales charge-voltage settings to
compensate for ambient temperatures.) The hot, cold, and warm settings are used
if a battery temperature sensor is not present. The hot setting is the default.

Installation

975-0126-01-01 41

Battery Types

For the purposes of this discussion, there are two principal types of batteries:
starting and deep-cycle. Batteries are either sealed or vented. However, there are
even different kinds of these batteries. This section explains some of the
differences among lead-acid batteries to help you choose a battery that best suits
your needs.

Your RS2000 Sine Wave Inverter/Charger is designed for use with deep-cycle,
lead-acid batteries. These batteries are designed for deep discharge service where
they will be repeatedly charged and discharged. This type of battery is often
labeled as a marine, recreational vehicle, or golf cart battery . Xantrex recommends
that you use one or more deep-cycle batteries separated from the starting battery
of your vehicle or boat.

Starting Batteries

Do not use starting batteries with your inverter; they will wear out rapidly in a
deep-cycle application. The way they are rated gives a good indication of their
intended use: “Cold Cranking Amps” is a measure of the amperage output of a
battery intended for starting or “cranking” an engine.

Starting batteries use many thin plates to maximize the surface area of the battery .
This allows very high starting current. In a deep cycle application, these batteries
will limit the number of cycles that can be supported before the battery needs to be
replaced.

Deep Cycle Batteries

Deep-cycle batteries are best suited for use with inverters. They are designed to
have the majority of their capacity used before being recharged. Available in
many sizes and types, the most common is the non-sealed, liquid electrolyte type
referred to as a “flooded (or wet)” battery , comm only used in both bo ats and RVs.
Non-sealed types have removable battery caps. The caps should be removed at
least monthly so the electrolyte level can be checked. When a cell is low, only
distilled water should be added. “Spring” water and regular tap water may have
high mineral levels which can poison the battery chemistry and reduce battery
life.

Deep-cycle, lead-acid batteries can be grouped into five categories:

• Flooded (or wet)

• Sealed flooded (“maintenance free”)

• Recombinant flooded (often “starved electrolyte”)

• Gel batteries

• AGM

Installation

42 975-0126-01-01

Another popular and inexpensive battery of this type is the “golf cart”
(T -105 or CG220 or US 2200 ) battery . These six-volt batteries can be connected in
series to form a 12V system and can be discharged repeatedly to 80% of their
capacity without being severely damaged. This is the minimum quality of battery
that should be used with the inverter in normal applications.

Some systems use the L16 type of battery. These are 6-volt batteries rated at
350Ah and are available from a number of manufacturers. They are 17 inches (43
cm) high and weight up to 130 pounds (60 kg) each — which maybe be
troublesome in some installations.

Type 8D batteries are available in either cranking or deep-cycle construction. The
deep-cycle versions are 12-volt batteries rated at approximately 200 Ah. Since
they are mostly commonly used to start truck engines, you should make sure you
purchase the deep-cycle version, not the cranking version. Type 4D batteries are
very similar in construction but are somewhat smaller (approximately 170 Ah).

Sealed Gel-Cell

Another type of deep-cycle battery is the sealed gel-cell. The electrolyte is in the
form of a gel rather than a liquid and never requires topping up. Battery caps are
not removable. The sealed construction allows the batteries to be mounted in any
position without spilling. The advantages are no maintenance (to the battery itself
the system still requires routine maintenance), long life (800 cycles claimed), and
low self-discharge. The disadvantages are high initial cost and the possibility of
damage form overcharging.

While many manufacturers produce quality flooded (or wet) batteries, only a few
produce suitable gel-cells. Don’t confuse gel batteries with maintenance-free
batteries, which are typically standard flooded (or wet) electrolyte batteries
without caps for adding water, and when the electrolyte gets low, you replace the
battery.

AGM (absorbed glass mat) batteries are similar to gel-cells and deep-cycle types
and can be used in inverter applications.

Environment

For long life and good performance, batteries need to be located in a protected,
ventilated enclosure insulated from temperature extremes.

Location

Batteries should be located in an accessible location that allows for access to the
battery caps and terminals. At least twelve to eighteen inches of clearance above
the batteries is recommended. They must be located as close as possible to the
inverter/charger to keep the cable run short. However, do not locate the batteries
in the same space as the inverter/charger unless they are of the sealed gel-cell
type.

Installation

975-0126-01-01 43

Enclosures

Batteries must be protected inside a ventilated enclosure. The enclosure should be
ventilated to the outdoors from the highest point to prevent the accumulation of
hydrogen gases released in the charging process. An air intake should also be
provided at a low point in the enclosure to allow air to enter the enclosure to
promote good ventilation.

Temperature

Effect of cold
temperature

The effective capacity of a battery is reduced when the temperature is cold. This
phenomenon is more significant with lead-acid type batteries than with alkaline
types. When the internal temperature of a lead-acid battery is 32 °F (0 ° C), the
capacity can be reduced by as much as 50%. This effectively reduces the size of
the system’s “gas tank,” requiring more frequent “refueling” by the charger. This
should be considered when you design the system. If extremely low temperatures
are expected where the system is going to be located, a heated equipment room
should be considered.

Benefits of
insulated enclosure

If the system is located in an unheated space, an insulated enclosure is highly
recommended for the batteries. During the charging process, the batteries release
heat due to the internal resistance of the battery. If the batteries are insulated, the
heat can be kept in the batteries to keep them warmer. This will substantially
increase the performance of the system.

Insulated battery enclosures also ensure that the temperatures of individual battery
cells are more consistent. This prevents unequal charging, which can cause battery
failure (some cells being overcharged while others are undercharged).

Protect batteries
from high
temperature

The batteries should also be protected from high temperature. This can be caused
by high ambient temperatures, solar heating of the battery enclosure , o r heat
released by an engine or generator located close by. High battery temperature
results in short battery life and should be avoided by ventilating the enclosure and
reducing the external heat sources by shading and insulation.

Battery Bank Sizing

Purchase as much
battery capacity as
possible

Battery size or capacity is just as important as the battery type selected for use
with your RS2000 Sine Wave Inverter/Charger. The batteries are the most
important part of your system, so Xantrex recommends that you purchase as much
battery capacity as possible. A large battery will extend running time and ensure
that your inverter/charger delivers full rated surge. Your inverter/charger can be
configured to work with batteries from 50 Ah (120 reserve minutes) to 2000 Ah
(4800 reserve minutes).

Battery capacity 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 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.

A typical marine or RV battery rated for 100 Ah can deliver 5 amps for 20 hours
(5A x 20 hours =100 Ah). This same battery can delivery a higher or lower current
for less or more time, limited approximately by the 100 Ah figure (50 A for 2
hours or 200A for 1/2 hour), but usually the capacity figure given is only accurate
at the specified rate (20 hours).

The minimum battery size you can use with the RS2000 Sine Wave Inverter/
Charger is 50 Ah. However, you can expect performance to suffer with such a
small battery. Even if your battery is in excellent shape and is fully charged, you
will likely experience poor surge power performance and unsatisfactory operating
time with anything but a small AC load.

Xantrex recommends a minimum
battery size of 200 Ah for moderate loads (<1000W) and greater than 400 Ah
for heavy loads.

Installation

975-0126-01-01 45

Estimating Battery Requirements

To determine the proper battery bank size, you need to compute the number of
amp-hours that will be used between charging cycles. When the required amp­hours are known, size the batteries at approximately twice this amount. Doubling
the expected amp-hour usage ensures that the batteries will not be overly
discharged and extends battery life. To compute total amp-hour usage, determine
the amp-hour requirements of each appliance that is to be used and then add
together, or the watt-hour can be totaled and converted to amp-hours.

Start with the nameplate rating of your appliances. If the wattage is marked on the
appliance, you can use that number directly. Otherwise, multiply the marked
voltage and amperage: WATTS = VOLTS X AMPS.

Once you know the AC wattage drawn from the inverter, multiply that amount by
the length of time the appliance will be used to determine the energy the load will
require: WATT-HOURS=WATTS X HOURS. You can then convert this to an
estimate of the battery amp-hours that the appliance requires.

BATTERY AMP-HOURS USED=AC WATT-HOURS/10 (for a 12-volt battery)
—or—
BATTERY AMP-HOURS USED=AC WATT-HOURS/20 (for a 24-volt battery)
For example, a 100 W light bulb that is used for 4 hours will use 400 watt-hours

(Wh) and the inverter will consume approximately 40 Ah from a 12 volt battery,
or 20 Ah from a 24 volt battery.

Another useful rule of thumb is that the current drawn from the battery can be
estimated from the AC output watts by using these same factors (10 for 12 volt
systems, 20 for 24 volt systems). For example, when running an 800 W
microwave oven, the inverter will draw approximately 800 divided by 10 = 80A
from a 12 volt battery.

Motors are normally marked with their running current rather than their starting
current. Starting current may be three to six times running current. Motors are
normally marked with their running current rather than their starting current.
Starting current may be three to six times the running current. The specification
that is important in determining whether an inverter will start the motor or not is
the locked rotor amps. This specification may be abbreviated to LRA or LRI. In
general, if the surge capability of the inverter is in excess of the listed LRA, the
inverter will start the motor. The RS2000 can surge to 5000VA for 5 seconds; this
means that the RS2000 should be able to start a motor with an LRA of less than
40A.

If large motors will be started, you may need to increase the battery size to allow
for the high start-up demand.

Battery Bank Sizing Example

The following battery sizing example illustrates a typical calculation, assuming an
opportunity to charge the battery every three days:

Table 1-1

Battery Sizing Example

This example illustrates how quickly your battery needs can escalate. To reduce
the required battery bank size, you can either conserve energy by eliminating or
reducing the use of some loads, or recharge more frequently.

When sizing your battery , be conservative and 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. Batteries can be connected in parallel, in series, or in
series-parallel to create higher capacity systems. It is not recommended to connect
batteries from different manufacturers, different types, or that have different amp­hour ratings in parallel. Improper charging and decreased battery life will result.
See “Cabling & Hook-up Configurations” on page 52 for more information about
battery inter-connection schemes.

Monthly Battery Maintenance

Read the section “Personal Precautions When W orking With Batteries” on page ix
prior to working on batteries.

❐ Check electrolyte levels in flooded (or wet) batteries

Flooded (or wet), lead-acid batteries require periodic water refills in each
battery cell. Check the level of the electrolyte in each battery cell at least once
a month. The level should be above the top of the plates, but not completely
full. (Most batteries have a plastic cup that just touches the electrolyte when
the cell is full.)

Refill the batteries with distilled water only. “Spring” water and regular tap
water may have high mineral levels which can poison the battery chemistry
and reduce battery life.

When filling the battery, clean the surface first to prevent dirt from entering
the cell. Fill the cell to just above the plates.

Don’t overfill the batteries, or the electrolyte will leak out when the batteries
are being charged.

Check the water level in the batteries frequently when performing an equalize
charge and add water if necessary.

❐ Check battery connections for good contact with the terminals. See “Checking

battery connections” on page 50.

❐ Maintain battery terminals. See “Reducing corrosion on battery terminals” on

page 51.

❐ Check specific gravity with hydrometer.

Make sure readings are in accordance with the battery manufacturer’s
specifications.

WARNING: Risk of acid burns

Wear appropriate clothing, eye protection, and rubber gloves when carrying out
battery maintenance activities

WARNING: Risk of fire, explosions, burns

Use caution when wearing jewellery or working with metal tools around
batteries. Do not allow any metal object to contact both battery terminals at the
same time. Battery explosion or failure can occur.

Preparation for Cleaning Batteries

Dirty batteries can leak current and tend to run hotter. Ultimately, this affects the
performance of your inverter/charger, resulting in inefficient inverting and
incomplete charging. Cleaning batteries when necessary is easy and safe when
you follow these instructions.

Gather what you need before beginning the procedure. The appropriate clothing,
tools, equipment, and supplies are listed as follows.

Clothing

Appropriate clothing could include old clothe s, rubber boots, or old shoes. Battery
acid is highly corrosive, so wear something you can discard just in case you splash
some acid on yourself. Be sure to wear rubber gloves and eye protection.

Tools

❐ Adjustable wrench or appropriately sized ratchet and sockets for battery

terminals

❐ Adjustable and/or locking pliers
❐ Torque wrench (suggested, not required)
❐ Soft-bristled brush (a discarded toothbrush works fine)
❐ 6 inch scrub brush
❐ Inexpensive 1/2 inch chip brush or soldering brush
❐ Hydrometer

Equipment

❐ Eye protection
❐ Rubber gloves
❐ Water hose with spray nozzle or five gallon watering bucket
❐ Empty spray bottle

Supplies

❐ Baking soda (Always keep on hand in the event of a spill.)

Maintaining and Cleaning

Follow the appropriate procedures for maintaining and cleaning the

• battery enclosure

• battery terminal and cable lugs

• battery cables

Battery Enclosure and Batteries

The battery enclosure should be cleaned as required, for example, if you see liquid
on the battery. Also wipe off the top of batteries.

Mix four ounces of baking soda with a gallon of fresh water. Fill a spray bottle
with the solution. Spray the solution on all exposed surfaces of the battery
compartment, and wash down the exposed surfaces of the batteries and their
enclosure. Scrub stubborn areas with the scrub brush. Baking soda will neutralize
any acid that may have collected on these surfaces. Finish by rinsing with water.

Terminals & Lugs

Checking battery
connections

Periodically check the battery connections for corrosion and tightness of battery
terminals and cable lugs. Check every time you perform battery maintenance.

Loose battery terminals and cable lugs exposed to open air corrode rapidly. The
corrosion appears as a white powder or granular foam on the terminals and on any
nearby exposed metal parts. This is actually a crystallized form of sulfuric acid. If
the corrosive contacts your skin, it will cause burns unless you rinse it off
immediately. Most textiles that are exposed to this corrosive eventually dissolve.

The most common cause of battery system failure is loose or corroded battery
terminals and cable lugs. If any white powdery residue forms between the battery
cable lug and the battery terminal, remove the cable for cleaning. When it is
necessary to detach a battery cable from the battery, disconnect all loads and
charging sources. Using the appropriate tool, remove the negative (–) battery cable
first and re-install it last.

To remove any stubborn residue, sprinkle baking soda directly on the area, and
scrub with a wet toothbrush (or other soft-bristle brush). Ensure that all caps are on
tight so the solution doesn’t enter the battery . Add water as required and then rinse
the top of the battery with clean water.

WARNING

Review the “Important Safety Instructions” on page v before you begin.

Installation

975-0126-01-01 51

Reconnect the battery cable terminals to the battery cable lugs and tighten to
battery manufacturer’s specifications. If you do not have a torque wrench, use an
appropriate tool to tighten the bolts reasonably snug. Do not over-tighten.

Reducing corrosion
on battery terminals

After tightening the cables, evenly coat all of the exposed metal surfaces of the
battery terminals and cable lugs with liquid neoprene (liquid electrical tape). Do
not apply anything between the battery terminal and the cable lugs; the connection
should be metal to metal.

The liquid neoprene cures to form an airtight protective layer and reduce the
amount of corrosion on the battery terminals. If liquid neoprene is not available,
use a light coating of white lithium grease or other sealant.

Battery Cables

Inspect all of the battery cables for missing or damaged insulation or loose
connections. Inspect any openings that the cables pass through. All such openings
must be equipped with a rubber grommet or conduit to prevent chafing on the
battery cable. If necessary, re place worn grommets. If the cable insulation is worn,
replace the battery cables.

Cabling & Hook-up Configurations

Several smaller batteries can be connected to create a battery bank of substantial
size. You can connect batteries in three ways: in parallel, series, or series-parallel.

T o make a larger battery bank, connect individual batteries with heavy cables. The
actual size of the cable depends on whether the batteries are connected in parallel
or series. Generally, the cable should not be smaller than the inverter cables—if
the main cables are 4/0 AWG, the battery interconnects should be 4/0 AWG.

The best configuration is to connect the batteries in series and parallel. This
requires additional cables, but reduces imbalances in the battery bank and can
improve the overall performance. Consult your battery supplier for more
information regarding the hook-up configuration required for your system.

Parallel Connection

Batteries are connected in parallel when all the positive terminals of a group of
batteries are connected and then, separately, all the negative terminals are
connected. In a parallel configuration, the battery bank has the same voltage as a
single battery, but an Ah rating equal to the sum of the individual batteries. See
Figure 16.

Series Connection

When batteries are connected with the positive terminal of one battery to the
negative terminal of the next battery, th ey are connected in series. In a series
configuration, the battery bank has the same Ah rating of a single battery, but an
overall voltage equal to the sum of the individual batteries. See Figure 17.

Series-Parallel Connections

As the name series-parallel implies, both the series and parallel configurations are
used in combination. The result is an increase in both the voltage and the capacity
of the total battery bank. This is common with all battery-inverter system
voltages. The smaller, lower voltage batteries are first connected in series to
obtain the necessary voltage, and then these “batteries connected in series” sets
are connected in parallel to increase the battery bank capacity. See Figure 18.
