INTRODUCTION

This owner’s manual describes the
Fleet Power
Xantrex Technology Inc. This unit performs
three distinct functions:

1. DC to AC power inverting.

2. Automatic transfer switching between
inverter power and incoming AC power.

3. Automatic three-stage battery charging
plus manual battery equalizing.

• The inverter provides regulated 120 volt AC
power at a crystal controlled frequency from a
deep-cycle battery bank and is rated at 3000
watts.
The output is a modified sine wave and is
compatible with most appliances, tools and
other 120 VAC equipment. (Note: certain laser
printers, breadmakers, digital clocks and small
battery chargers may not operate on modfied
sine wave.) An idle mode reduces battery
power consumption when loads are removed
from the inverter. There is a low battery cutout
protection circuit and momentary surge power
of more than twice the inverter rating for start­ing electric motors. High efficiency ensures the
longest possible battery life between charges.

TM

3000-12 Inverter/Charger from

• The FP3000-12 battery charger is
electronically controlled and rated at a
maximum output current of 140 amps DC.

It is designed to rapidly and optimally charge
wet, gel, or Absorbed Glass Mat (AGM)** cell

deep-cycle batteries. Battery charging is
automatically accomplished in three stages:
Bulk Charge, Acceptance Charge and Float
Charge.

Using a Remote Control Panel, a manually
engaged Equalizing Charge cycle is possible.
Simple, automatic operation is made possible
by the microprocessor in the FP3000-12. In
most cases, no attention or maintenance is
required.

Electronic Protection

Fast-acting electronic circuits protect the
inverter from overloads and short circuits.
Other protection includes a low and high
battery voltage cutoff and automatic shutdown
if an over-temperature condition occurs. When
the fault condition is corrected, the unit will
automatically reset. Example: remove over­load, charge batteries or allow to cool.

• The internal transfer switch allows the
FP3000-12 to be connected to an external AC
source and transfer the source power through
directly to the loads. When the external AC
power source is disconnected, the transfer
switch allows automatic switching back to the
inverter.

The FP3000-12 operates as a self-contained
backup power system—just add batteries.

**Battery type selection is set on the front of the unit
or with the Remote Control Panel.

THINGS YOU SHOULD KNOW

Circuit Breaker Protection

The FP3000-12 is supplemental breaker
protected.

The INVERT/CHARGE breaker on the front of
the unit protects against sustained inverter/
charger over-current conditions. These breakers
are reset by pushing the button back in. The
output circuit breakers protect the output AC
circuits. The FP3000-12 is available with one
or two outputs.

Thermostat Controlled Cooling

The FP3000-12 is equipped with a thermostati­cally controlled fan that cools the unit so it can
operate continually at its rated Units with only
supplemental circuit breakers between the unit
and the load. Appropriate wire gauges must be
used throughtout the installation. Refer to NEC
specifications.

noitcetorPrekaerBtiucriC

Inverter Idle Circuit

This automatic energy-saving feature
reduces battery power consumption when no
AC load is present. Response from idle is
instantaneous. In most cases, the operation of
the idle circuit is not noticeable. Use of the
Remote Control Panel allows the idle threshold
to be adjusted. The unit does not put out 120
volts when in idle. To bring the unit out of the
idle condition, apply a load.

Low and High Battery Shutdown

When in inverter mode, if the battery
voltage drops to 10.0 volts, the inverter will
automatically shut off. Charge the batteries to

13.5 volts to automatically resume operation.

Voltage shutdown also occurs for a high battery
condition at 15.5 volts. Operation will resume
automatically when the battery voltage drops
below 15.5 volts. Check all DC sources on
the system for the reason for the excessive
voltage.

GHC/VNI1TUO2TUO

03A/NA/N

Note: Supplemental circuit breakers are reset by pushing the
button back in. The fault must be removed before resetting the
circuit breaker. Integral branch circuit rated breakers are reset
by setting the appropriate breaker switch to the “on” position.
The fault must be removed before resetting the circuit breaker.

If a 30-ampere service supplies the input to the unit, a model
with integral branch circuit rated breakers allows direct wiring
from the unit to the load.

Power Sharing

When connected to an external AC source
the battery charger and transfer functions are
engaged. A unique Power Sharing feature
automatically reduces the AC power consump­tion of the battery charger allowing necessary
AC power to go to the load. This prevents the
source AC INPUT circuit breaker from tripping
within the specified rating of the AC circuit
breaker.

The Power Sharing set point of each unit has a
factory default setting of 30 amps. This can be
changed using the Remote Control Panel.

THINGS YOU SHOULD KNOW

Temperature Sensitive Charging (TSC)

When the supplied battery temperature sensor is
connected to the unit and the batteries, the
charge voltage is controlled based on battery
temperature. The charger adjusts the charge
voltage to the best level, minimizing water loss in
wet cell batteries. Charge voltage regulation opti­mizes the battery life cycle.

OPERATION

The FP3000-12 provides 120 volt AC power
from auxiliary DC batteries, automatic battery
charging and automatic AC transfer switching
between an external AC source and inverter
mode.

External AC Power

When external AC power is available, the
three-stage battery charger, transfer switching,
and Power Sharing automatically function.

When external AC power is not available and
the INVERT switch is ON (either through the
auxiliary switch or the INVERT button on the
remote), the inverter will automatically turn ON.
If the INVERT switch is OFF (the INVERT LED
will not be illuminated), the inverter will be OFF.

If installed with the Remote Control Panel, the
unit will be set up and controlled from the
remote. Refer to the remote manual for more
information.

The CHARGE LED will be solid green.

• When the LED is blinking slowly, (once
per second) the charger is ready, but external
AC power is not available.

• Press the CHARGE switch again to turn
the charger OFF. The charger defaults to ON
when operating without a remote or with the
Remote Control Panel.

• When the LED is OFF, the charger has
been manually turned OFF. This can only be
accomplished while AC power is being supplied.

NOTE: When AC power is available, the default
setting for the charger is ON. If the unit was
manually turned OFF and AC power is inter­rupted and becomes available again, the
charger will return to ON.

LOW BATTERY - Red LED

• When the LED is OFF the battery voltage

is normal, between 10.5 and 15.0 volts DC.

• When the LED is solid red, it indicates a
battery warning condition, the battery voltage is
below 10.5 volts DC or above 15.0 volts DC.

• When the LED is blinking slowly (once
per second), a battery shutdown has occurred.
The voltage is either below 10.0 volts DC or
above 15.5 volts DC.

• When the LED is blinking rapidly (five
times per second), a potential problem in the
DC system has been detected. Check your
batteries, battery cables and DC loads.

OVERTEMP/OVERLOAD - Red LED

• When the LED is OFF, operation is

normal.

• When the LED is red, there is an over
temp or overload condition. Check for
excessive loads or short circuit on the output
of the inverter. Correct the condition and restart
by pushing the INVERT switch.

short circuit has occured. The system has
shut OFF and will not automatically restart.
Correct the fault condition and manually restart
the system.

LOW BATTERY & OVERTEMP/OVERLOAD

- Red LEDs

• When both LEDs are blinking, an AC
backfeed has been detected. A backfeed occurs
when AC power from an external source is
connected to the output of the inverter. Inspect
wiring for a possible input/output wiring error.
This condition will damage the unit and must
be corrected before further operation.

BATTERIES

Wet cell batteries will give off gas as a natural
result of charging and will experience some
water loss. It is very important that the
electrolyte level be checked frequently and
topped off with distilled water when necessary.
Follow the battery manufacturer’s
recommendations for maintenance.

Never allow the top of the battery plates to be
exposed to air, as contamination of the cell will
result. Keep the top of batteries clean. Always
provide adequate ventilation for the battery
storage compartment.

BATTERY TYPES

Use only deep-cycle batteries with your
FP3000-12. These fall into three broad
categories: wet cell, gel cell and Advanced
AGM (Absorbed Glass Mat) batteries.

Wet Cell Batteries

True deep-cycle wet cell batteries are
characterized by relatively thick internal plates
that are alloyed with antimony.

Common 12-volt marine/RV deep-cycle
batteries are acceptable. Golf cart
batteries perform well and may have a
longer life. These 6-volt batteries must be
used in series connected in pairs. High
quality deep-cycle batteries offer good
performance and are available in a wide

variety of sizes.

Do not use ordinary car batteries or engine
starting batteries with your inverter
Beware of any battery that is rated in Cold
Cranking Amps (CCA). This is a rating which
applies only to engine starting batteries. In
general, most wet cell batteries that are
described as hybrid type batteries, suitable for
either engine starting or deep-cycle applications,
are a compromise and will have limited life if
deeply discharged.

·charger.

11

BATTERIES

All batteries can be maintenance free, but not
all of them are deep-cycling batteries. Beware

of batteries that are described as
maintenance free only. These batteries have

calcium alloyed with the lead and hold the
liquid electrolyte in a sponge-like material. They
are sealed and water cannot be added. Do not

confuse them with true gel cell or AGM
batteries—they will not hold up well to deep

discharging and repeated cycling.

Gel Cell Batteries

Gel cell batteries are lead-acid batteries similar
in many ways to the common wet cell battery,
but differences in the chemistry and
construction provide some unique features.

• No maintenance

• Low self-discharge rate

• Low internal resistance

Even though gel cells are sealed batteries, the
battery compartment should still be ventilated.

BATTERY INTERCONNECTION

In most cases, you will be using a bank of two
or more batteries with your inverter

/charger.

You may connect batteries together in two
configurations, series and parallel, depending
on their voltage.

Series

Connecting two batteries in series will double
the voltage of the battery bank. For instance,
two 6-volt batteries connected in series will
produce 12 volts. The amp-hour capacity of
the battery bank will be the same as each
individual battery. For example, two 6-volt 220
amp-hour batteries in series will produce one
12-volt 220 amp-hour battery bank.

+

+

+

Advanced AGM (Absorbed Glass Mat)
Batteries

This battery is lead acid but maintenance-free.
The performance is similar to gel cell batteries.
The charge parameters are similar to wet cell
batteries.

Battery Selection

The most important feature to consider in
making your battery selection is to select true
deep-cycle batteries rated in amp hours (Ah)
and sized to match your power requirements.

Note: It is not advisable to connect batteries of

same battery bank.

Always use properly sized wire and
terminals for your interconnecting battery
cables. For size information refer to NEC
requirements or contact your local
electrician.

BATTERY BANK RATINGS AND SIZING

Deep-cycle batteries are usually rated in amp
hours. The amp-hour rating is based on a 20­hour discharge rate. Therefore, a 100
amp-hour battery can deliver 5 amps for 20
hours. If the discharge rate is greater than 5
amps, the available amp hours are decreased.
For example, if the load is increased to 100
amps, only about 45 amp hours will be avail­able at this rate of discharge.

Deep-cycle batteries can be discharged about
80% of capacity before damage occurs.
Shallow cycling will result in much longer
battery life. Calculating a battery bank size
based on 50% discharge cycling is generally
considered to be a good compromise between
long battery life and size.

Only similar batteries should be connected
together in one bank. Do not connect old

and new batteries together or wet and gel cell
batteries together. In the above drawing, the
load is connected to the positive terminal of
the first battery and the negative terminal of the
last battery. This practice helps to balance the
battery bank and is called cross-connecting
the battery bank.

13

BATTERIES

To achieve 50% cycling you should calculate
your amp-hour consumption between charging
cycles and use a battery bank with twice that
capacity**. Each AC appliance or tool has a
rating plate on it and will be rated in either AC
amps or watts or AC VA (volt-amps) apparent
power. To calculate amp-hour consumption,
use one of the formulas to the right to calculate
the DC amp-hour draw for a 12 volt system.

Calculate the amp hours for every AC
appliance or tool that will be operated on the
inverter. This will provide the total number of
amp hours used between recharges. Size the
battery bank using this number as a guideline.
A good rule to follow is to size the battery bank
a minimum of two times larger than the total
amp-hour load requirement. Plan on recharging
when 50% discharged.

**Batteries are typically charged to 85% of full charge
when charging with alternators without three-stage
regulators.

AMP-HOUR CONSUMPTION FORMULAS

(AC amps x 10) x 1.1 x hours of
operation = DC amp hours

(watts/ DC voltage) x 1.1 x hours of
operation = DC amp hours

(AC VA/ DC voltage) x 1.1 x hours of
operation = DC amp hours

DC voltage is 12, 24 or 32,

depending on your system.

In all formulas, 1.1 is the correction factor for

inverter efficiency.

Typical Power Consumptlon

The chart identifies typical power consumption
for common AC loads. Use it as a guide when
identifying your power requirements.

Many electric motors have momentary starting

requirements well above their
operational rating. Start-up watts
are listed where appropriate.

may not operate on modified sine wave.

BATTERY CHARGING

Battery Charging

Completely charging wet cell deep-cycle bat­teries requires the battery voltage to be raised
beyond what is known as the gassing point.
This is the voltage at which the battery begins
to bubble and gas is given off. If charging stops
short of this point, sulfate is left on the plates
and deterioration of the battery begins. The
gassing point will vary with battery temperature.

At 77 °F, the gassing point of a 12-volt battery
is about 14.0 volts.

AGM and gel cell batteries must not be
charged to their gassing point. In fact, high
voltage charging which gasses these batteries
is harmful to them. They typically require a
lower bulk charge voltage and a higher float
voltage than wet cell batteries. Consult the
battery manufacturer for specifications.

Fleet Power Battery Chargers

Fleet Power battery chargers are designed to
overcome the limitations of conventional
chargers by utilizing three distinct charge
stages, each designed for optimal charging of
wet, gel cell and AGM deep-cycle batteries.
Battery type selection is made on the front
panel of the inverter/charger or through the
Remote Control Panel. For more information
on battery type selection, see page 7 or refer to
the Remote Control Panel manual.

15

BATTERY CHARGING

NOTE: The FP3000-12 is ON whenever AC
power is connected to the charger input. The
charger can be turned OFF using the
CHARGE switch on the front of the unit. This
sequence will occur each time external AC
power is available. The charger can be turned
ON/OFF using the Remote Control Panel.

Each time the battery charger is engaged, the
three-stage charger proceeds automatically,
resulting in an efficient complete charge and
safe battery maintenance. Use of the Remote
Control Panel provides the ability to periodically
apply an equalizing charge.

Refer to Remote Control Panel owner’s
manual for more information.

16

The battery charger stages are:
Stage 1 - Bulk Charge During the bulk

charge stage most of the energy that has been
consumed during discharge is returned to the
battery bank. This phase is engaged as soon as
the battery charger is activated. Full rated charger
current is delivered to the battery bank until the
acceptance charge voltage limit is reached.
This results in a relatively rapid recharge.

Generally, a wet cell battery bank should not
be charged at a rate that exceeds 25% of its
capacity.

BATTERY CHARGING

Gel cell and Advanced AGM batteries can
accept a higher rate of charge. Consult the
manufacturer for specifications.

Stage 2 - Acceptance Charge The
acceptance stage immediately follows the bulk
charge stage. During this stage the battery
voltage is held constant at the bulk charge
voltage limit and the current gradually ramps
down. During this stage the battery is accepting
its final amount of charge current and the last
of the sulfate on the plates is removed.

The acceptance stage lasts until the charge
current reaches the transition point. A timer will
terminate the acceptance stage if this current
level is not reached.

ACCEPTANCE TO FLOAT TRANSITION POINT

FP3000-12

Maximum acceptance time is one hour for wet
and AGM cells and three hours for gel cells.
Gel cell acceptance time can be longer because
they are less likely to gas. Expect wet cell bat­teries to gas somewhat during acceptance—this
is a necessary part of the charging process.

15 Ampere DC

The float charge stage holds the battery voltage
constant at a preset lower level, where it is
safe for long-term battery maintenance. During
the float charge stage, the full output current of
the battery charger is available to operate any
DC appliances that may be on the system,
while constantly maintaining the float charge
voltage.

The battery charger remains in the float charge
stage indefinitely until the charger is discon­nected from incoming AC power or turned OFF
on the unit or with the Remote Control Panel.

Stage 4 - Equalizing Charge This is the only
battery charger stage which is not engaged
automatically. It must be manually initiated
each time. Applying an equalizing charge is
possible only with a Remote Control Panel.

Periodic equalizing is recommended by most
wet cell deep-cycle battery manufacturers.
There are no firm rules for how often an equalizing
charge should be applied. Follow the battery
manufacturer’s recommendations for equalizing.

Stage 3 - Float Charge When the
acceptance stage is terminated, either
because the charge current ramped down to
the transition point or the timer engaged, the
charge current will shut off. The unit monitors
the battery voltage while it drifts down from the
acceptance charge voltage limit. When it
reaches the float voltage set point, the float
charge stage is engaged.

17

BATTERY CHARGING

The equalizing charge is a timed, eight-hour
cycle. The cycle can be ended early by inter­rupting the AC power to the charger at any
time during the cycle. Equalizing should only
be engaged after the batteries have been fully
charged by a normal battery charging cycle.

During this equalizing stage, the battery
voltage will increase to the equalize voltage.
This will cause the battery bank to gas
profusely and will accomplish the following:

1. Removal of residual sulfate. Each time a
battery is cycled (discharged and charged), a
small amount of sulfate is left on the plates.
Over time, this gradual buildup of sulfate will
compromise the performance of the battery.
By applying an equalizing charge, the sulfate is
returned back to the electrolyte, raising the
specific gravity and fully exposing the active
material of the plates.

2. Bring all cells to the same potential.

All lead-acid batteries are made up of individual
2-volt cells. As the battery bank is cycled, slight
differences in the cells result in different cell
voltages, affecting the overall charge
effectiveness. Equalizing brings all cells to the
same voltage and the electrolyte in each cell to
the same specific gravity.

3. Mixing up of the electrolyte. Electrolyte in
battery cells tend to separate into layers of acid
and water. The vigorous bubbling action of the
battery during equalizing serves to physically
mix the electrolyte. Refer to the Remote
Control Panel owner’s manual for additional
cautions on equalizing.

Note: Do not equalize gel cell batteries.

18

WARNINGS

1. Do not equalize gel cell batteries.

Check remote default settings.

2. Always monitor the equalize charge
cycle. Provide proper ventilation for

battery fumes. Do not allow any sparks
during equalizing. If one or more cells begin
to overflow, terminate the equalize cycle.

3. Check the battery electrolyte both
before and after the equalizing charge.

Do not expose the battery plates to air.
Leave the battery caps on while equalizing.
Top off after equalizing.

4. Remove all loads from the DC system
before equalizing. Some DC loads may

not tolerate the high charge voltage.

BATTERY CHARGING

5. With the Remote Control Panel the
battery state-of-charge LEDs sequence
during equalizing. When the equalization
cycle is complete, the charge automatically
goes to float and the green float LED bat­tery status light is on.

INSTALLATION

CAUTION Risk of electrical shock. Do not

remove cover, no user serviceable parts
inside. Refer servicing to qualified service

personnel.

The FP3000-12 is appropriate for
installation in recreational vehicles (RVs), work
vehicles, and other applications.

It is recommended that installation be com­pleted by an authorized Xantrex technical
dealer or experienced electrician.

Key Installation Points

1. The unit is designed to mount
horizontally (on a shelf).

2. Allow several inches of clearance around

the unit to permit a supply of fresh air to the
cooling fan. Do not block any of the vents or
louvers. The thermostat controlled fan pulls air
from outside the unit. It pulls air across the
internal components, particularly the trans­former and heat sinks, then out the fan vent.

3. Keep the inverter
elements and out of direct contact with
water or spray. Failure to do so may result in

premature malfunction from corrosion and void
the warranty.

4. Mount the unit as close to the batteries
as possible but not in the presence of

flammable fumes or in an enclosed battery
compartment.

/charger out of the

5. Keep the overall length of each battery
cable less than 10 feet. Do not use frame

ground or a ground bonding system as a
current-carrying conductor. Run the negative
(-) cable directly to the battery bank. If the
positive (+) and negative (-) cables run parallel
to each other, twist the cables together. This
will minimize the inductive adverse effects of
cable length. Be sure the cable size meets
with NEC requirements for your installation.

6. Make sure all wiring conforms to local
and national electrical codes. If in doubt,

consult with a qualified electrician.

7. To meet electrical codes, a UL Listed DC
Rated slow blow fuse must be installed in the
positive battery cable within 18 inches of the
battery post. This fuse is intended to protect
the battery and cables against a short circuit.
The inverter is protected internally and will not
blow a properly sized fuse.

8. Do not connect the battery until you
have read the remainder of the installation
section. Observe proper polarity when

connecting batteries. Reverse DC polarity will
result in damage to the unit and will void the
warranty. Use care when making the DC
connections.

WARNING

Do not mount the unit in an enclosed
battery compartment. Take precautions to
keep dirt and spray off the unit.

22

WARNING

The FP3000-12 is not DC reverse polarity
protected. Be very careful to connect the
negative and positive cables correctly,
otherwise damage will result and the
warranty will be void.

INSTALLATION

9. Do not backfeed the AC output of the in­verter with incoming AC power. A backfeed

occurs when AC power from shorepower or
generator is connected to the output of the in­verter. This will damage the inverter and void
the warranty. Remember that
must be fed only to the AC input and never the
AC output. Always check for AC voltage before
connecting wires to the AC output. Do NOT
turn the inverter ON until all AC connections
have been made. Backfeeding the inverter
voids the warranty.

incoming AC

WARNING

Do not connect incoming AC from any
source to the AC output of the inverter.
This is known as backfeeding and will
damage the unit and void the warranty.

10. Do not connect the AC input to the AC
output. This would be equivalent to plugging

the battery charger into the inverter. This could
occur if the unit’s AC output is connected to the
entire leg of a circuit breaker panel, then a circuit
breaker on that leg is used to feed the battery
charger input. This will cause the unit to oscillate
ON and OFF when the unit is in inverter mode.

tons using a hexagonal die. The T&B die has a
code number of 54. After the crimp is made,
the barrel of the terminal and the first inch of
the cable needs to be covered in UL Listed or
UL Recognized heat shrink tubing. Xantrex
recommends a 2-inch length of 3M HDT 0800
tubing. Other heat shrink may be used if it is
UL Listed or UL Recognized as long as the
manufacturer’s directions are followed.

12. If installing in a system which includes an
existing battery charger or AC to DC converter,

make sure these do not operate from the
inverter output AC power. This sets up a

power loop which, due to inefficiencies, will
quickly drain the batteries.

13. An Auxiliary Switch port is located on the
front panel of the unit, covered by a flap. When
installing the unit for operation without a
Remote Control Panel, a jumper must be
installed in the Aux Switch port. The jumper is
shipped in a plastic bag with other installation
parts. DO NOT install the jumper until all cable
connections have been made.

When using a Remote Control Panel, the
jumper is not used.

11. Always use proper wire and connectors.

The proper battery cable size is critical. Con­siderable amperage flows in the DC circuit.
For the FP3000-12, use 3/0 AWG UL Listed
Welding Cable terminated on each with UL
Listed or UL Recognized ring terminal connec­tors. For the terminal, use Thomas & Betts
(T&B) part number BAL 2038. Be sure the
connectors are attached to the cable using a
method approved by the connector manufac­turer. For the connections to meet all require­ments, T&B recommends that each terminal
be crimped in two places with a pressure of 15

INSTALLATION

Grounding

For safety purposes, the chassis of the inverter
charger must be connected to your AC ground
system. Use 8 AWG bare copper or green
insulated wire, strip one end and use a screw­driver to secure it to the chassis ground bonding
lug on the side of the unit. This wire will connect
to the ground in your AC electrical system.
Make sure the connection is clean and tight.

The system AC ground bonding terminal is
located on the front of the unit under the
wiring cover at the bottom of the unit. This
connector is for the bare copper or green
ground wires from the AC branch circuit supply
and to the AC loads or distribution panel. It is
important that these AC input and AC output
ground wires connect to the AC ground bus in
the circuit breaker panels.

Some installations require heavier grounding
wire. Conform to local and national electrical
codes.

More information on grounding can be found
in the National Electrical Code and local
electrical codes.

/

Note: The battery cables are not connected
to the AC ground strip or to the chassis lug
of the unit.

Neutral Bonding

For safety purposes and NEC code
requirements, the FP3000-12 unit internally
bonds the AC output neutral (white) to the AC
output ground (green), when the unit is OFF or
in the inverter mode. When incoming AC
power is applied and the transfer switch is
engaged, the internal neutral-to-ground bond is
automatically lifted.

When external AC power is applied, the
grounding system is connected to the source
power ground, where neutral and earth ground
are bonded together. This technique ensures
safety in all conditions and conforms to the
requirements of the NEC.

WARNING

Do not connect incoming AC from any
source to the AC output of the inverter
charger. This is known as backfeeding
and will damage the unit and void the
warranty. The Over Temp/Overload and
Low Battery LEDs will be blinking rapidly if
this condition exists.

Remote Control Wiring

If installing a remote panel, route the remote
cable and connect to the Remote jack on the
front of the unit. Refer to the Remote Control
Panel Owner’s Manual for more information.

TSC Temperature Sensor

If installing the TSC (Temperature Sensitive
Charging) sensor, connect the ring terminal
end to the positive battery post, complete the
routing of the RJ11 cable (15 feet supplied) and
connect the plug end to the TSC jack on the
front of the unit.

DC Wiring

DC wiring is generally very simple—the
positive (+, may be red for identification) and
negative (-, may be black or yellow for
identification) cables from the inverter/charger
terminal posts are connected to the house or
auxiliary battery. Connection to the engine
starter battery is not recommended.

High current will pass through the DC wiring.
All wires must be properly sized and all
connections clean and tight. It is
recommended that the battery cable length
does not exceed 10 feet.

Battery cables should be connected to the
inverter/charger before any connections are
made to the battery. Follow the battery
hardware stackup diagram.

• Remove the negative (-) battery cable
cover from the unit and attach the battery
cable. Tighten the battery terminal bolts to a
torque value between 160 inch-pounds and
180 inch-pounds. Replace the cover for the
negative terminal before removing the cover for
the positive terminal.

The positive (+) battery cable must be fused
and connected to the positive post of the
house or auxiliary battery bank, or through a
selector switch to one or more battery banks.

A spark may be generated when the final
battery connection is made. This is normal; do
not be alarmed. However, do not make the final
connection in the presence of flammable fumes.

If multiple batteries are used, the
interconnecting jumper cables must be the
same AWG or larger as those connected to
the inverter/charger.

If multiple battery banks are to be charged, a
battery bank selector switch can be installed,
allowing the banks to be charged either
individually or simultaneously. A solenoid can
also be used.

NOTE: If installing in a vehicle, do not use the
vehicle frame as the negative conductor.

Follow these instructions to ensure proper
startup and confirm that the installation is correct.

1. Check to make sure Invert and Charge are
OFF. The INVERT LED should not be
illuminated, the CHARGE LED should be
blinking (charger ready but no external AC
power available). If using a Remote Control
Panel, make sure inverter and charger are OFF.

2. Check battery polarity. If the unit was con­nected to the battery with reverse polarity, the
unit will be damaged.

INSTALLATION

WARNING

Do not turn the inverter ON before
eliminating any possibility of backfeed.

• Add a load of 7 watts or more to the output
of the inverter. A 40-watt incandescent light
bulb will work fine. The DC Amps LEDs on the
remote will indicate the DC draw from the
battery through the inverter.

3. Check the battery voltage and ensure it is
within proper range for the unit (10–15.5 VDC).

4. Install the jumper in the Auxiliary Switch port
(AUX SWITCH), if using the inverter without re­mote. If operating the inverter with a remote,
the jumper should

Do not apply shorepower or generator
power without performing the following
steps:

1. Test the inverter function:

• With no loads connected to the output of
the inverter, turn the INVERT Switch ON. The
INVERT LED should be blinking green. If using
a remote, turn ON the inverter with the switch
on the Remote Control Panel.

• The FP3000-12 will produce a slight buzz.
If using a Remote Control Panel, the INVERT/
CHARGE LEDs will illuminate and the voltage
indicator will display the battery voltage. The
DC Amps LED will not be lit because the unit
is in the idle mode.

not be used.

• Leave the load connected and turn OFF
the INVERT mode by pressing the INVERT
switch or turn OFF the INVERT mode from the
Remote Control Panel.

2. Test the transfer function:

• Be sure the unit is OFF, the INVERT and

CHARGE LEDs are not illuminated. Apply
shorepower. If there is a backfeed in the
installation, the unit will protect itself, the LOW
BATTERY and OVERTEMP/OVERLOAD LED
will both be blinking rapidly (five times per
second). Do not proceed until the backfeed
condition has been corrected.

• Once shorepower has been applied to the
unit, there will be approximately an eight­second delay. Then the unit should transfer
shorepower and power the load. If this does
not happen, do not proceed. If the LOW BAT­TERY and OVERLOAD/OVERTEMP LEDs
are blinking rapidly or if you are using a Remote
Control Panel, check the panel for backfeed
indication. The panel will show an overload
condition. Eliminate the backfeed condition.

29

INSTALLATION

• Testing for backfeed. If a backfeed
condition is indicated, disconnect from
shorepower and disconnect the AC output
wires on the inverter. Make sure the inverter is
OFF. Apply shorepower and measure for volt­age between the black and white wires that
were attached to the inverter output feeding the
electrical panel or loads, not the inverter output
wires. If there is voltage on these wires, a
backfeed condition exists and must be corrected
or damage will result.

3. Test the battery charger function:

• With shorepower applied and the transfer
switch engaged, the battery charger should be
in operation. The CHARGE LED will blink for
eight seconds. After the eight seconds, the unit
will enter the charge mode and the LED will be
illuminated. (NOTE: When using Temperature
Sensitive Charging, this time may be longer.)

NOTE: When AC is available, the unit will auto­matically default to charge mode without the
operator setting the unit in CHARGE mode. If
you do not want to charge, it is necessary to
press the CHARGE switch OFF.

• Turn the INVERT ON—the green LED
should blink. Remove shorepower and the
inverter should automatically pick up the AC load.

NOTE: For low power system shut down
mode, both the INVERT and CHARGE LEDs
must be OFF.

Repeat the test for transfer and battery charger
with the generator if you have one.

Congratulations, you have completed a
successful installation.

Verify the charger is working by using a
voltmeter. The battery voltage should gradually
increase. If using a Remote Control Panel, the
DC Amps LED indicates the current the
charger is putting out and the DC Volts LED
indicates an increase in battery voltage.

GLOSSARY

Alternating Current (AC) An electric current

that reverses direction at regular intervals.
Sources of alternating current are shorepower,
generator power, inverter power or household
current.

Ampere (amp, A) The unit of measure of
electron flow rate of current through a circuit.

Amp hour (Amp-Hr., Ah) A unit of measure for
a battery’s electrical storage capacity, obtained
by multiplying the current in amperes by the
time in hours of discharge. (Example: a battery
which delivers 5 amperes for 20 hours delivers
5 amperes times 20 hours, or 100 amp hours
of capacity.)

Amp-Hour Capacity The ability of a fully
charged battery to deliver a specified quantity
of electricity (Amp-Hr., Ah) at a given rate
(amp, A) over a definite period of time (Hr.).
The capacity of a battery depends upon a
number of factors such as: active material,
weight, density, adhesion to grid, number,
design and dimensions of plates, plate spacing
design of separators, specific gravity and
quantity of available electrolyte, grid alloys, final
limiting voltage, discharge rate, temperature,
internal and external resistance, age and life of
the battery (bank).

AGM (Absorbed Glass Mat) Battery A lead
acid, maintenance-free battery.

AWG (American Wire Gauge) A standard
used to measure the size of wire.

Circuit An electric circuit is the path of an
electric current. A closed circuit has a
complete path. An open circuit has a broken or
disconnected path.

Circuit (Series) A circuit which has only one
path for the current to flow. Batteries arranged
in series are connected with the negative of the

first to the positive of the second, negative of
the second to the positive of the third, etc. If
two 6-volt batteries of 50 amp-hours capacity
are connected in series, the circuit voltage is
equal to the sum of the two battery voltages, or
12 volts, and the amp-hour capacity of the
combination is 50 amp hours.

Circuit (Parallel) A circuit which provides
more than one path for current flow. A parallel
arrangement of batteries (of like voltage and
capacity) would have all positive terminals
connected to a conductor and all negative
terminals connected to another conductor. If two
12-volt batteries of 50 amp-hour capacity each
are connected in parallel, the circuit voltage is 12
volts, and the amp-hour capacity of the
combination is 100 amp hours.

Current The rate of flow of electricity or the
movement rate of electrons along a conductor.
It is comparable to the flow of a stream of water.
The unit of measure for current is ampere.

Cycle In a battery, one discharge plus one
recharge equals one cycle.

Direct Current (DC) Current that flows
continuously in one direction such as that from
batteries, photovoltaics, alternators, chargers
and DC generators.

Equalize Charge A controlled overcharge of
the batteries which brings all cells up to the
same voltage potential, extends the battery life,
restores capacity and mixes the electrolyte.
This can only be done using the Remote
Control Panel.

Gel Cell Battery A type of battery that uses a
gelled electrolyte solution. These batteries are
sealed and are virtually maintenance free. Not
all sealed batteries are the gel cell type.

33

GLOSSARY

GFCI (Ground Fault Circuit Interrupter) A

protective device that rapidly de-energizes a
circuit when current to ground exceeds a
predetermined value.

Ground The reference potential of a circuit. In
automotive use, the result of attaching one
battery cable to the body or frame which is
used as a path for completing a circuit in lieu of
a direct wire from a component. This method is
not suitable for connecting the negative cable of

INSTALLATION OPTIONS

Installation Option #1

The inverter is used in a Single Input/Single Output mode. Up to 30 amps is transferred
through the FP3000-12 with the charger sharing power with all of the AC loads.

In this installation example, a single 30-amp shorepower source is available and all AC loads are
supplied power through the inverter in charge/transfer mode, or by the inverter in invert mode.
The charger shares power with the AC loads and can transfer up to 30 amps. The AC input
power must be supplied through a 30-amp branch rated main breaker.

In this type of system, the panel loads would normally not include any heavy loads such as
space heaters, stove, water heaters, air conditioners, AC to DC converters, or other battery
chargers. If these types of loads are present, they should be turned OFF when the inverter
power is being used to prevent overloading the inverter or rapidly discharging the battery
bank. To avoid the need for this manual form of energy management, installation option #2
should be considered.

If a generator is installed in the system, a break-before-make AC transfer switch is used to se­lect between shore or generator power. The transfer switch AC output is then routed to the input
of the inverter/charger.

INSTALLATION OPTIONS

Installation Option #2

The AC loads are split between main loads and “inverter loads.” The external sources
of AC power can be a single 30-amp shorepower source or a 30-amp breaker from a
panel fed by a 50-amp 120 volt single phase (three wire) shorepower source, 1 leg of a
50-amp 120/240 split phase (four wire) shorepower source, or a generator. The charter
shares power with the “inverter loads” only.

In this installation example, one single-phase shorepower source is available or only one leg of a
split-phase source is used to supply the AC input of the inverter/charger. It is highly recom­mended that only the lighter appliance and outlet circuits be connected to the inverter AC panel.
These loads are supplied power through the inverter in charge/transfer mode, or by the inverter
in invert mode. The charger shares power with the “inverter loads” only and can transfer up to 30
amps. The heavier loads such as space heaters, stove, water heater, air conditioners, AC to DC
converters, or other battery chargers, should remain connected to the main AC panel. These
loads are only supplied by shore or generator power from the main panel. This split load approach
will help avoid problems such as overloading the inverter or rapidly discharging the battery bank,
and eliminate the need to manually manage the energy usage of these loads when using
inverter power.

The inverter AC input must be supplied power from a 30-amp breaker in the main panel and
from the main neutral bus. The inverter’s AC output supplies a separate sub panel. The appli­ance and outlet loads are then supplied with power from the inverter hot and neutral bus in the
sub panel.

If a generator is installed in the system, a break-before-make AC transfer switch is used to select
between shore or generator power. The transfer switch AC output is then routed to the input of
the main AC panel.
