1.2 System Features
•Inverter
The inverter consists of two sine wave inverters built into one unit. A “low power“ high efficiency 70 watt
inverter supplies power for the small loads. The “high power” 4,500 watt main inverter supplies power
when AC loads over 70 watts are applied. Designed for maximum efficiency this system conserves battery
power when only small loads are present. To further conserve battery power the Load Demand feature
allows the inverter to ‘go to sleep’ if AC loads fall below a selected value. Load Demand may be disabled if
very small AC loads must be operated.
The inverter develops up to 4,500 watts of continuous power. Using TruSine®technology, a very high
quality pure sine wave is produced. Total harmonic distortion (THD) is less than 2.0 percent.

System Features and Specificatiions
TruSine 4.5 kW Inverter Page 5 Owner’s Manual
•Battery Charger with Automatic Power Management
A high efficiency 100 amp multi-stage battery charger allows fully automatic charging of flooded and gel
lead acid battery banks. The efficient 0.85PF, compared to typical 0.59PF on triac type chargers, allows
full charger output from a 30 amp aux AC source. The system’s Bulk - Absorption - Float charge cycle
quickly charges and maintains the charge on the battery bank. An Equalization charge cycle is provided
for flooded lead acid battery maintenance.
Automatic Power Management (APM) monitors the Aux AC Input amps and will reduce the battery
charger output as needed to keep the Aux AC Input amps below the preset APM Limit.
•Automatic AC Power Transfer Switch with Solar Mode
An automatic AC transfer switch provides system output power sourced from the Aux AC Input (generator
or utility) or sourced from the battery, via the inverter. Solar Mode allows the inverter to operate on battery
power while shore power is present.
•Gen Start
The Gen Start feature provides a start/stop signal to control a generator used for recharging the batteries.
The start/stop signal consists of a contact closure to start the generator based on battery voltage and stop
the generator based on battery charging amps.
•System Control
The TruSine contains a System ON/OFF Switch to turn the system ON and OFF. A control
microprocessor provides a variety of protection interlocks, system fault detection/reporting/recovery,
storage of system data parameters, and high speed data communications to the optional TSR-2 Remote
Control Panel. System protection functions include over load, over temperature, and high and low battery
voltage. Use the ON/OFF Switch to reset the system after shutdown for a system fault. The optional TSR-
2 Remote Control Panel provides a system status display and allows detailed control of individual system
functions.
•TSR-2 TruSine Remote Control Panel (Optional)
The optional TSR-2 Remote Control Panel / Programming Panel is an
operator interface which connects to the TruSine Inverter/Charger via a 6-
conductor data bus and allows system operation near the inverter or from
remote areas. Multiple TSR-2 Remotes may be connected for optimum
flexibility. The TSR-2 contains an alphanumeric LCD display and functional
keypad making it easy to use. System status messages are displayed, faults
are reported, system functions may be enabled/disabled or turned ON/OFF,
system setpoints may be examined and changed.
Figure 2: TSR-1 and TSR-2 Control Panels
Earlier production TSR Remotes, the TSR-1, are identical to the TSR-2 except contain early software used
with TruSine inverter/charger model TSC24-4000D. The TSR-1 will work with TruSine 4500 models but cannot
access the GenStart and other new features of the TruSine 4500. The TSR-1 may be upgraded to TSR-2
status by changing software to part number A88769-A or newer. TSR-2 software is displayed upon startup and
also is identified in the General Information Menu step 52. TSR-1 software is identified in the System Info
menu.

Description of Operation
TruSine 4.5 kW Inverter Page 7 Owner’s Manual
2 DESCRIPTION OF OPERATION
2.1 Inverter
The System ON/OFF Switch, located on the front panel, allows the user to turn the system ON and OFF and to
reset the system after a fault. The inverter will always begin operation in the large inverter “high power” mode. If
the AC load is less than 70 watts the inverter will automatically switch to the “low power” high efficiency small
inverter after 5 seconds. The optional TSR-2 Remote Control Panel allows the inverter to be disabled (turned
OFF) while allowing the other system functions (charger, transfer switch) to continue to operate.
The Inverter AC Output Circuit Breaker is a 2 pole, 20 amp breaker marked “O/I” located below the System
ON/OFF Switch. The breaker protects the Inverter AC output and Battery Charger AC input against a severe
overload. This breaker does not protect AC Passthrough Power. If the breaker trips during inverter operation,
the system must be reset. Do this by turning the System ON/OFF Switch OFF and back ON. Do not use the
AC Output Circuit Breaker as an ON/OFF switch.
Protective Interlocks
Auto-restart After shutting down for any of the following fault conditions the inverter will try to restart
itself every 5 minutes. The inverter will restart if the fault condition is no longer present.
Manual restart Manually restart the system by resetting the inverter after the fault conditions is removed.
Reset the inverter by turning the System ON/OFF Switch OFF and then ON.
Low Battery The inverter continually monitors battery voltage. If battery voltage falls below the Low
Battery Shutdown setpoint the inverter will shut OFF. Auto-restart will restart the inverter
after battery voltage rises above the Low Battery Warning setpoint.
High Battery The inverter will shut OFF if battery voltage rises above the High Battery setpoint.
Over Temperature The inverter will shut OFF if internal temperature sensors detect a high temperature
condition that would damage the inverter.
While operating in Solar Mode a high temp shutdown will transfer back to shore power until
the over-temperature condition clears.
Over Load - If a short circuit or an overload is applied to the inverter’s output the inverter will shut down.
Additional details regarding protective interlocks are found in the Alarm Menu in section 3.
Load Demand
The TruSine Inverter’s Load Demand Mode is an energy-saving feature. Load Demand allows the inverter to go
to sleep when the AC load is below the ‘Enter Load Demand’ (watts) setpoint for 5 seconds. While in Load
Demand (asleep) the inverter produces only pulses of AC which are used to search for an AC load. When the
inverter senses an AC load greater than the ‘Exit Load Demand’ (watts) setpoint, the inverter will turn fully ON.
The Load Demand feature significantly reduces the DC amps drawn from the battery while the AC load is below
the Load Demand enter and exit setpoints.
The inverter will not enter Load Demand from the High Power mode. The inverter will only enter Load Demand
from the 70 watt small inverter Low Power mode.
The ‘Enter Load Demand’ and ‘Exit Load Demand’ setpoint values may be adjusted to suit the AC loads by
using the optional TSR-2 Remote Control. The Load Demand feature may be turned OFF by selecting Load
Demand enabled/DISABLED. This is recommended if very small AC loads under 5 watts, such as clocks or
LCD displays, must be operated.
2.2 Battery Charger
The battery charger’s advanced design incorporates an automatic, multi-stage charger. This design enables

Descriptions of Operation
TruSine 4.5 kW Inverter Page 8 Owners Manual
the unit to automatically charge batteries which maintains the battery’s integrity and reduces the likelihood of
premature battery failure. The battery charger is designed to be used with lead-acid type batteries including
sealed and gel types, but not for nickel-cadmium (Ni-Cad) or nickel-iron types.
Battery Charging Sequence
Stage 1: Bulk Charge Stage
The charger always starts in the Bulk Charge
Stage each time shore power becomes present
and/or each time the charger is turned ON. In
Bulk Charge the system charges at the ‘Bulk
Charge Amps’ setpoint until battery voltage rises
to the ‘Bulk Charge Voltage’ setpoint. Then the
voltage is held at that setpoint until charging
amps have fallen to 5 amps above the ‘Battery
Absorption Amps’ setpoint. This ends the Bulk
Charge Stage and begins the Absorption
Charge Stage. The charger will not enter the
Bulk Stage again until shore power is reapplied,
or until the charger or the system is turned ON again.
Stage 2: Absorption Charge Stage
The Absorption Charge Stage provides a controlled “overcharging” of the battery which is necessary to bring
the battery up to full charge. The battery is charged at the ‘Absorption Charge Amps’ until one of following three
conditions occur which signals the end of the Absorption Stage;
Time: The Absorption Maximum Time setpoint is reached
Time: The Absorption Charge Stage has reached ½ of the duration of the Bulk Charge Stage.
Voltage: Battery voltage reaches the ‘Absorption Voltage’ setpoint
Stage 2A Equalize Charge Cycle
When Equalize Mode is ENABLED, one Equalize Charge Cycle will follow the Absorption Charge Stage. The
Equalize Cycle will last for the ‘Equalize Time’ setpoint. Equalize Mode will automatically switch to DISABLED at
the end of the Equalize Charge Cycle. During the Equalize Cycle the battery is charged at the ‘Absorption
Charge Amps’ setpoint and the Equalize Voltage setpoint.
The Equalize Charge Cycle provides a deliberate overcharging of the battery to remove sulfate which
accumulates on the battery plates through normal use. Equalizing returns battery cells to equal performance
levels which improves battery performance and extends battery life. Consult the battery manufacturer for their
recommendation regarding equalize voltages how often the Equalize Cycle should be performed.
CAUTION
Do not equalize sealed (valve regulated lead acid or gel) batteries! Consult battery manufacturer for
equalizing guidelines. Do not equalize more often than approximately once a month. Check battery fluids after
equalizing is complete, as gassing will occur. Use Equalize Mode only while batteries are well ventilated!
Stage 3: Float Charge Stage - Maintenance Mode
In the Float Stage the charging voltage is reduced to the ‘Float Charge Voltage’ setpoint and charging current is
limited to the ‘Absorption Charge Amps’ setpoint. The charger will remain in the Float Stage until shore power is
reapplied, or until the charger or system is turned OFF and then ON again.
Charging Setpoints
The TruSine’s battery charger factory setpoints are for wet batteries. Do not use the factory setpoints for gel
batteries. If gel batteries are used, consult the battery manufacturer for charging recommendations. Setpoints
for typical gel batteries are listed and may be used if specific recommendations are not available from the gel
battery manufacturer.
Caution: Do not operate DC loads, such as DC lights, pumps, etc., during battery charging. The loads may
cause overcharging by preventing the charging stages from reaching their ‘trigger points’ or may cause the
battery to run down even though the charger is ON.

Equalize Maximum Time Wet only 5 - 30 15 Minutes Not used
Battery ‘C Rate’ is equal to battery Amp Hour capacity.
Automatic Power Management (APM)
A key feature of the battery charger operation is Automatic Power Management (APM). This feature monitors
the Aux AC input amps and will reduce the battery charger output as necessary to keep the Aux AC input amps
under the APM setpoint. The APM circuit will not limit power to the passthrough AC loads. If the passthrough
AC loads exceed the APM setpoint the battery charger output will be reduced to zero.
Adjust the “APM Limit” setpoint to match the circuit breaker at the Aux AC source. This will reduce the chance
of tripping the source’s circuit breaker due to battery charging.
On model TSC24-4500D (240VAC) the APM feature monitors L1 and L2. APM decisions are based on the
heavier loaded line.
Example: With the APM Limit on a TSR24-4500D set at 15 amps, L1 loaded to 15 amps and L2 has no
load, then the APM will allow no power to go to charging. If the load on L1 is reduced to 10 amps then
the charger will be allowed to use 5 amps.
2.3 Automatic Transfer Switch with Solar Mode
The Automatic Transfer Switch consists of electro-mechanical relays controlled by circuits which monitor Aux
AC input voltage, Aux AC Input frequency and battery voltage.
In the normal mode of operation, Solar Mode OFF, the Automatic Transfer Switch will automatically accept ‘in-
tolerance’ Aux AC input power whenever it is available within tolerance for the ‘AC Line Stabilization’ time delay.
The Aux AC input power will be used to operate the battery charger and to passthrough to operate AC loads.
Upon loss of ‘in-tolerance’ Aux AC input power, the transfer switch will automatically transfer the AC loads back
to inverter power. Transfer time is approximately 40 milliseconds (0.040 seconds). The 0.040 second transfer
time allows all but the most sensitive loads to transfer from inverter power to shore power and back without
interruption.
The Transfer Switch will function properly as long as the System ON/OFF switch is ON even while the Inverter
is disabled, while the Battery Charger is disabled or while the batteries are disconnected from the system.
The Transfer Switch switches both hot and neutral. For safety purposes the inverter output neutral is connected
to the inverter chassis ground only when the system is in inverter mode. This is a requirement of the National
Electric Code for all systems of this type that neutral should be connected to ground only at the source of AC
power, which is the inverter when in inverter mode. When Aux AC input (shore power, or generator) is
available, the Transfer Switch system breaks the connection between neutral and inverter chassis ground. The
neutral-to-ground connection for passthrough power is then expected to be provided by the Aux AC input
source. This transfer scheme presents no problems for a properly installed system. The installer should verify
that all AC circuits connected to the inverter AC output are an insulated neutral type as required by the National
Electrical Code (NEC) article 551.
Solar Mode
Turn Solar Mode ON in applications where it is preferred to operate on battery power while ‘in tolerance’ Aux
AC input (shore power) is avaliable. With Solar Mode ON, the inverter will operate on battery power while Aux
AC input is available until battery voltage falls below the Low Battery Warning setpoint. Then the system will

Descriptions of Operation
TruSine 4.5 kW Inverter Page 10 Owners Manual
accept Aux AC input, the batteries will be Bulk charged and the system will switch to inverter again.
2.4 Gen Start
The Gen Start feature is designed for use in installations having a generator to provide Aux AC input power for
battery charging. The Gen Start feature provides a contact closure to signal the generator to start when battery
voltage falls below the ‘Gen Start Volts’ setpoint. The Gen Start contacts open when bulk charging amps fall
below the ‘Gen Stop Amps’ setpoint. Bulk charging amps are sampled every 4 minutes, therefore the minumum
generator ON time is 4 minutes. The contacts are NEC Class 2, rated 2 amps at 12 or 24 VDC.
Gen Stop Amps should be set higher than the Absorption Charge Amps setpoint.
Caution: The battery charging process will be affected if 24VDC loads are being powered during battery
charging. The increased charger output, required to power those loads, may keep the charger from reaching
the ‘Gen Stop Amps’ setpoint.
3 TSR-2 Remote Control Panel (optional)
3.1 General Description The TSR-2 TruSine Remote Control Panel is an optional
display/keypad module that allows the installer to adjust the
system operation factory setpoints and allows the user to
monitor and control in detail the TruSine Inverter/Charger
operation. The TSR-2 connects to the inverter at the V-NET
Port. One or more control panels may be installed to provide
the necessary level of system control and flexibility. The
TruSine Inverter/Charger System setpoints will not change
after removal of the TSR-2 Remote.
TSR-2 Control Panel
The TSR-2 TruSine Remote Control Panel contains a 32 character (two 16 character lines) liquid crystal display
(LCD), a red Alarm LED indicator, and a functional keypad. A menu scheme is used to allow the operator to
select and control system functions, and to display information. In the event of a system fault the Alarm LED will
illuminate and a fault message will be displayed. The TSR-2 Remote connects to the inverter’s V-Net Port via a
6 conductor modular data communication cable. The unit is supplied with a 25’ long cable with a 6-pin RJ-11
connector at each end.
Early production TSR-1 Remotes, used with earlier model Vanner inverter/chargers, are identical to the TSR-2
but will need the software upgraded to A88769-A to access the GenStart and other new features in the TruSine
4500 Inverter/Charger. TSR-2 software is identified in the General Information Menu step 52. TSR-1 software is
identified in System Information step 53 for theTSC24-4000D.

5 INSTALLATION
Unpacking the Inverter
Inspect the shipping container and equipment for loose or damaged parts. If any damage is found, immediately
notify the freight carrier.
5.1 Basic Guidelines
The wiring of your inverter installation should conform to the National Electric Code (NEC) and any other state
or local codes in effect at the time of installation. These codes have been written for your protection and their
requirements should be followed.
Mounting
Locate a secure, dry, flat horizontal or vertical surface large enough to mount the inverter. The location should
be as close to the battery as possible without being in the same compartment and should provide adequate
ventilation to maintain room temperature while the inverter is operating. The location must allow unobstructed
cooling air flow at sides and bottom of the unit, and the location must be free from road spray, dripping water or
other moisture contamination. A recommended minimum clearance of 4 inches (102 mm) should be
maintained on all sides of the unit.
WARNING: Risk of fire or explosion. The inverter must not be mounted in fuel storage areas, battery
compartments, or other areas hazardous locations requiring ignition protection.
NOTE
The wiring of your inverter installation should conform to the National Electric Code (NEC) and any other state
or local codes in effect at the time of installation. Article 551 of the NEC requires any DC cable from a battery,
which measures longer than 18 inches along its length, be protected by a fuse. Other codes may require each
ungrounded output conductor from a storage battery, other than to the engine cranking motor, to have a
manually reset trip-free circuit breaker or fuse within 72 inches of the battery as measured along the conductor.
5.2 DC Wiring
Preliminary Considerations
1. BE AWARE that, as a large number of capacitors become charged upon completion of the DC circuit,
THERE WILL BE A LARGE SPARK when the last battery connection is made. The spark is normal and will
occur every time the batteries are connected.
2. The DC cables should be as short as possible. It is electrically more efficient to run the lower current AC
wiring longer distances than the DC cables. (See DC Cable Sizing Chart for proper size.)
3. Route the DC positive and negative cables as close together as possible, and use cable ties to keep them
together. This reduces some electromagnetic radiation that could interfere with some sensitive electronics.
3. On vehicle installations do not use the vehicle chassis as the DC negative conductor. Use a cable the same
size as the DC positive to go directly from the inverter to the battery negative.
4. Route the AC and DC power wiring separately, and with as much physical separation as possible, from low
voltage wiring such as audio and video signal wires.

Installation
TruSine 4.5 kW Inverter Page 20 Owners Manual
5. DC power input cables which pass through steel or other ferrous metal walls need to pass through the same
hole. If two holes are required, cut a slot connecting the two holes to prevent a transformer effect.
6. Do not allow wire fragments or metal shavings to fall into the DC wiring compartment or to enter the inverter
in any way. Severe inverter damage will result which is not covered by the warranty.
7. Do not connect the inverter to the battery at this time. Final battery connections will be made after all
installation issues have been inspected.
8. WARNING: A poorly made high current connection may result in risk of fire and personal injury.
9. WARNING: Be sure of the polarity of the DC input wiring. Reverse polarity may severely damage your
inverter and is not covered under warranty. Risk of fire or explosion of batteries may occur due to very high
currents.
10.A DC fuse is required to properly protect the inverter.
11.The table below shows the recommended minimum cable size which should be used. Wire sizing charts
published in the NEC may allow a greater amp capacity than we recommend. We have sized the cable for a
maximum voltage drop to maintain better performance of your inverter installation. The inverter’s DC cable
terminal lugs can accommodate cable sizes up to 250 MCM.

DC Wiring Installation
The DC input terminals are located in the field wiring compartment located at the front right side of the unit and
accessed from the top. The connections are compression terminals which require a stripped cable and are
tightened by an Allen wrench. The positive and negative cables enter the compartment through separate strain
reliefs located at the right front of the unit.
WARNING
Never make electrical connections "live". Make the connections to the inverter first and the battery last. Make
certain the ON/OFF control switch on front of inverter is in the OFF position before connecting to the battery.
NOTE
Severe damage to the inverter will result, which is not covered under warranty, if wire fragments or other metal
particles enter the inverter through the DC wiring compartment.
Procedure
Step 1: Turn the inverter OFF and disconnect all AC and DC power to the wiring harness. Make sure power
to the inverter wiring is disconnected. Verify that the inverter is turned OFF (the Inverter ON-OFF
switch is in the OFF position).
Step 2: Select a location for the unit. An ideal installation location has the following characteristics:
•Close to the battery (usually within six feet).
•Protected from the weather.
•Well ventilated.
Step 3: Route DC input cables. Route the negative and positive DC input cables from the inverter to the
battery. If required, protect cables where they contact hard, sharp edges.
Step 4: Install the in-line fuse. Install the in-line fuse in the red, positive DC input cable between the battery
and inverter, within 18 in. of the battery or DC wiring bus system.
Step 6: Connect the inverter to the battery.
A) Remove the cover plate on the DC cable compartment exposing the positive and negative Allen head
terminal lugs.
B) Remove the two Allen screws from the terminal lugs.
C) Strip the positive and negative DC cable ends 3/4 in.
