Important Safety Instructions
SAVE THESE INSTRUCTIONS!
This manual contains important instructions and warnings that should be followed during the installation,
operation and storage of all Tripp Lite Inverter/Chargers.
Location Warnings
• Do not mount unit with its front or rear panel facing down (at any angle). Mounting in this manner will seriously
inhibit the unit’s internal cooling, eventually causing product damage not covered under warranty.
• Install your Inverter/Charger in a location or compartment that minimizes exposure to heat, dust, direct sunlight and
moisture. Flooding the unit with water will cause it to short-circuit and could cause personal injury due to electric shock.
• For proper ventilation, allow a minimum 2 inches of clearance at front and back of the Inverter/Charger. To avoid overheating
the Inverter, the compartment that houses the Inverter/Charger must be properly ventilated with adequate outside air flow.
The heavier the load of connected equipment, the more heat will be generated by the unit.
• Do not install the Inverter/Charger near magnetic storage media, as this may result in data corruption.
• Do not install the Inverter/Charger near flammable materials, fuel or chemicals.
Battery Connection Warnings
• Multiple battery systems must be comprised of batteries of identical voltage, age, amp-hour capacity and type.
• Because explosive hydrogen gas can accumulate near batteries if they are not well ventilated, do not install batteries in a
“dead air” compartment. The battery compartment should have some ventilation to outside air.
• Sparks may result during final battery connection. Always observe proper polarity as batteries are connected.
• Do not allow objects to contact the DC input terminals. Do not short or bridge these terminals together. Serious personal
injury or property damage could result.
Ground Connection Warnings
• Safe operation requires connecting the Inverter/Charger’s Main Ground Terminal directly to the frame of the vehicle or
earth ground.
Equipment Connection Warnings
• Use of this equipment in life support applications where failure of this equipment can reasonably be expected to cause
the failure of the life support equipment or to significantly affect its safety or effectiveness is not recommended. Do not
use this equipment in the presence of a flammable anesthetic mixture with air, oxygen or nitrous oxide.
• You may experience uneven performance results if you connect a surge suppressor, line conditioner or UPS system to the
output of the Inverter/Charger.
• User must supply proper protection for wire openings in unit panels.
Operation Warnings
• Your Inverter/Charger does not require routine maintenance.
• Potentially lethal voltages exist within the Inverter/Charger as long as the battery supply is connected. During any service
work, the battery supply should therefore be disconnected.
• Do not connect or disconnect batteries while the Inverter/Charger is operating from the battery supply. Dangerous arcing may
result.

1. Overview and Features
1.1 Overview
• Tripp Lite’s APSX4048SW Sine Wave Inverter/Charger is a heavy-duty unit generating a pure sine wave in single-phase or
3-phase power from a 48V battery bank. The APSX4048SW can supply power to a wide range of connected equipment,
from heaters, air conditioners, refrigerators and vacuum cleaners to computers and peripheral devices. The APSX4048SW is
designed to work in heavy load conditions, so de-rating is unnecessary.
• The APSX4048SW’s smart charger is compatible with various battery types and sizes. The switch module automatically
diverts the energy transfer path between the Inverter and an AC input. When the AC source is lower than the transfer level,
the electrical path switches to the Inverter and draws power from the battery source. Otherwise, the load is powered by the
AC input.

1. Overview and Features
1.3 Optional Features
1.3.1 Operational Considerations
1. Cold Starting – This unit will cold start only at 60Hz. Do not use this feature if the connected equipment cannot handle a
60Hz frequency.
2. The unit continues to draw from the DC source in OFF mode in order to keep the microprocessor active. The batteries
may be depleted if in the unit is in OFF mode for extended periods of time. The unit will charge the batteries if placed in
STANDBY mode with an active A/C source.
1.3.2 Battery Temperature Port
This port allows connection of a Battery Temperature-Sensing Cable (sold separately). The sensing function prolongs battery
life by adjusting the charge float voltage level based on battery temperature. Connect the sensor cable to the RJ11 port
labeled BATTERY TEMP SENSOR. With user-supplied cyanoacrylate adhesive (“Super Glue”), secure the sensor to the top of
the battery near the negative terminal. Make sure that nothing, not even tape, comes between the sensor and the side of the
battery. If the sensor cable is not used, the Inverter/Charger will charge according to its default 25°C values.
1.3.3 Communication Port (for APSRMSW Remote Control)
This unit allows connection of the APSRMSW Remote Control (sold separately) through the inverter’s ASNET port for
remote monitoring. The remote control allows the Inverter/Charger to be mounted out of sight in a compartment or cabinet
and operated conveniently from a remote location. See the instructions packed with the remote control module for more
information.
2. Battery Charger
2.1 Mode of Operation
The internal battery charger and automatic transfer relay allow the unit to operate as a battery charger, an inverter or a switch.
An external AC power source (e.g. utility power or generator) must be connected to the inverter’s AC input in order to allow
it to operate as a battery charger. When the unit is operating as a charger, AC loads are powered by the external AC power
source.
2.2 Transfer Switching Speed
Transfer time is approximately 20 milliseconds.
3. Battery
3.1 Select Battery Type
Select “Deep Cycle” batteries to receive optimum performance from your Inverter/Charger. Do not use ordinary car or starting
batteries or batteries rated in Cold Cranking Amps (CCA). If the batteries you connect to the Inverter/Charger are not true Deep
Cycle batteries, their operational lifetimes may be significantly shortened. If you are using the same battery bank to power the
Inverter/Charger as well as DC loads, your battery bank will need to be appropriately sized (larger loads will require a battery
bank with a larger amp-hour capacity) or the operational lifetimes of the batteries may be significantly reduced.
Batteries of either Wet-Cell (vented) or Gel-Cell /Absorbed Glass Mat (sealed) construction are ideal. 6-volt “golf cart”, Marine
Deep-Cycle or 8D Deep-Cycle batteries in series-parallel connection are also acceptable. Auxiliary batteries must be identical
to the vehicle batteries if they are connected to each other.

3. Battery
3.1.1 Match Battery Amp-Hour Capacity to Your Application
Select a battery or system of batteries that will provide your Inverter/Charger with proper DC voltage and an adequate amp-
hour capacity to power your application. Even though Tripp Lite Inverter/Chargers are highly efficient at DC-to-AC inversion,
their rated output capacities are limited by the total amp-hour capacity of connected batteries and the support of your
vehicle’s alternator if the engine is kept running. Note: The minimum recommend battery capacity for the APSX4048SW is 50
amp-hours at 48VDC.
• STEP 1) Determine Total Wattage Required
Add the wattage ratings of all equipment you will connect
to your Inverter/Charger. Wattage ratings are usually
listed in equipment manuals or on nameplates. If your
equipment is rated in amps, multiply that number times AC
utility voltage to estimate watts. (Example: a drill requires
2.8 amps. 2.8 amps × 230 volts = 640 watts.)
NOTE: Your Inverter/Charger will operate at higher efficiencies at about
75% - 80% of nameplate rating.
• STEP 2) Determine DC Battery Amps Required
Divide the total wattage required (from step 1, above)
by the nominal battery voltage to determine the DC amps
required.
• STEP 3) Estimate Battery Amp-Hours Required
Multiply the DC amps required (from step 2, above) by
the number of hours you estimate you will operate your
equipment exclusively from battery power before you have
to recharge your batteries with utility- or generator-supplied
AC power. Compensate for inefficiency by multiplying this
number by 1.2. This will give you a rough estimate of how
many amp-hours of battery power (from one or several
batteries) you should connect to your Inverter/Charger.
NOTE: Battery amp-hour ratings are usually given for a 20-hour discharge
rate. Actual amp-hour capacities are less when batteries are discharged
at faster rates. For example, batteries discharged in 55 minutes provide
only 50% of their listed amp-hour ratings, while batteries discharged in 9
minutes provide as little as 30% of their amp-hour ratings.
• STEP 4) Estimate Battery Recharge Required, Given
Your Application
You must allow your batteries to recharge long enough to
replace the charge lost during inverter operation or else
you will eventually run down your batteries. To estimate
the minimum amount of time you need to recharge your
batteries given your application, divide your required
battery amp-hours (from step 3, above) by your Inverter/
Charger’s rated charging amps.

3. Battery
3.2 Monthly Maintenance
• Check the electrolyte level of each Wet-Cell battery cell monthly after the batteries have been charged. The level should be
about one-half inch above the top of the plates, but not completely full. Note: This check is not necessary for maintenance-
free batteries.
• Check the battery connections for tightness and corrosion. If any corrosion is noted, disconnect the cables and clean them
with a mild solution of baking soda and water. DO NOT ALLOW THE SOLUTION TO ENTER THE BATTERY. When finished, rinse
the top of the battery with clean water.
• To reduce corrosion on the battery terminals, coat them with a thin layer of petroleum jelly or anti-corrosion grease. Do not
apply any material between the terminal and the cable lugs; the connection should be metal to metal. Apply the protective
material after the bolts have been tightened.
3.3 Battery Installation
Caution! Batteries can produce extremely high currents. Review both the important safety
instructions at the beginning of this manual and the battery supplier’s precautions before installing
the inverter and batteries.
3.3.1 Battery Location
Batteries should be installed in an accessible location with good access to the battery caps and terminals. At least two feet of
overhead clearance is recommended. Batteries must be located as close as possible to the inverter. Do not install the inverter
in the same compartment with non-sealed batteries (sealed batteries are acceptable). The gasses produced by non-sealed
batteries during charging are highly corrosive and will shorten the life of the inverter.
3.3.2 Battery Enclosure
Batteries should be installed in a locked enclosure or room. The enclosure should be well ventilated to prevent accumulation
of hydrogen gasses that are released during the battery charging process. The enclosure should be made of acid-resistant
material or coated with an acid-resistant finish to prevent corrosion from spilled electrolyte and released fumes. If the batteries
are located outdoors, the enclosure should be rainproof and have mesh screens to prevent insects and rodents from entering.
Before installing the batteries in the enclosure, cover the bottom with a layer of baking soda to neutralize any acid spills.
3.4 Battery Connection
3.4.1 Connect your Inverter/Charger to your batteries using the following procedures:
• Connect DC Wiring: Though your Inverter/Charger is a high-efficiency converter of electricity, its rated output capacity is
limited by the length and gauge of the cabling running from the battery to the unit. Use the shortest length and largest
diameter cabling to provide maximum performance (see table below). Shorter and heavier-gauge cabling reduces DC
voltage drop and permits maximum transfer of current. Your Inverter/Charger is capable of delivering peak wattage at up
to 200% of its rated continuous wattage output for brief periods of time. Heavier-gauge cabling should be used when
continuously operating heavy-draw equipment under these conditions. Tighten your Inverter/Charger and battery terminals
to approximately 3.5 Newton-meters of torque to establish an efficient connection and to prevent excessive heating at the
connection. Insufficient tightening of the terminals could void your warranty.

3. Battery
• Connect Fuse: Tripp Lite recommends that you connect your battery to your Inverter/Charger’s DC terminals with wiring that
includes a fuse and fuse block within 18 inches of the battery. The fuse’s rating must equal or exceed the Minimum DC Fuse
Rating shown on the Inverter/Charger’s nameplate. See diagrams below for proper fuse placement. The battery wire with the
fuse should not be grounded.
WARNING!
• Failure to properly ground your Inverter/Charger to an earth ground may result in a lethal electrical
shock hazard.
• Never attempt to operate your Inverter/Charger by connecting it directly to output from an
alternator rather than a battery or battery bank.
• Observe proper polarity with all DC connections.
3.4.2 Connect the Batteries
When connecting batteries, your Inverter/Charger’s Nominal DC Input Voltage must match the number of batteries multiplied
by their voltage.
For example, a 48V DC Inverter/Charger requires four 12V batteries connected in series (48 = 4 x 12).
Contact Tripp Lite technical support for assistance with additional series or series/parallel connections.

3.4.3 Series-Parallel Connection
WARNING!
• Series-parallel connections are used with 3-phase power distribution in high-capacity industrial
and commercial installations. ONLY CERTIFIED PROFESSIONAL ELECTRICIANS SHOULD ATTEMPT
SERIES-PARALLEL CONFIGURATION AND 3-PHASE INSTALLATION FOR THE APSX4048SW INVERTER/
CHARGER.
In a series-parallel connection, there is an increase in both the voltage and the capacity of the total battery bank. This is done
by making larger, higher voltage battery banks out of several smaller, lower voltage batteries. Your Inverter/Charger’s Nominal
DC Input Voltage must match the number of batteries multiplied by their voltage.
For example, a 48V DC Inverter/Charger requires four 12V batteries connected in series (48 = 4 x 12). By adding additional
12V batteries in a series connection, you can increase the run time.
Contact Tripp Lite technical support for assistance with additional series or series/parallel connections.

4. Inverter/Charger Single-Phase Installation
4.1 Inverter/Charger Single-Phase Installation
4.1.1 Environment
The Inverter/Charger must be installed in a protected location that is isolated from sources of high temperature and moisture.
To obtain peak performance, battery cables should be kept as short as possible. However, do not install the Inverter/Charger
in the same compartment as non-sealed batteries. Accumulated hydrogen and oxygen generated by the batteries could be
ignited by an arc (resulting from connection of the battery cables) or by switching a relay.
The Inverter/Charger requires unrestricted air flow to operate at high power for sustained periods. Do not mount the inverter
in an enclosed space. This will restrict air flow and cause the inverter’s protection circuitry to activate, reducing maximum
available power.
4.1.2 System Grounding
Proper grounding is essential to ensure safe operation of the Inverter/Charger. Grounding requirements vary by country and
application. For specific requirements pertaining to your location and application, consult local codes and the NEC.

terminal of third first Inverter/Charger with an 8P terminator resistor.
For the final step, connect the second and third Inverter/Charger’s PARALLED STACKED INVERTER ports. Again using 6P wire
and RJ45 plugs, connect the right-side PARALLED STACKED INVERTER terminal on the second Inverter/Charger to the left-
side PARALLED STACKED INVERTER terminal on the third Inverter/Charger. Then connect the right-side PARALLED STACKED
INVERTER terminal of the third Inverter/Charger with a 6P terminator resistor.
4.4.5
The Inverter/Chargers should now be installed and connected for single-phase parallel operation. To enable single-phase
parallel configuration on the Inverter/Chargers, go to section 6.3.
Note: If the AC source power fails, the unit will work in Inverter mode. Otherwise, the system will switch to AC Mode and will power the load while charging the

5. Inverter/Charger 3-Phase Parallel Installation
5.1 Inverter/Charger 3-Phase Parallel Installation
WARNING!
• 3-phase power is an efficient energy source used solely in high-capacity
industrial and commercial installations. ONLY CERTIFIED PROFESSIONAL
ELECTRICIANS SHOULD ATTEMPT 3-PHASE INSTALLATION FOR THE APSX4048SW
INVERTER/CHARGER. Do not exceed more than six Inverter/Charger units in a
series-parallel connection.
5.1.1 Environment
The Inverter/Charger must be installed in a protected location that is isolated from sources of high temperature and moisture.
To obtain peak performance, battery cables should be kept as short as possible. However, do not install the Inverter/Charger
in the same compartment as non-sealed batteries. Accumulated hydrogen and oxygen generated by the batteries could be
ignited by an arc (resulting from connection of the battery cables) or by switching a relay.
The Inverter/Charger requires unrestricted air flow to operate at high power for sustained periods. Do not mount the inverter
in an enclosed space. This will restrict air flow and cause the inverter’s protection circuitry to activate, reducing maximum
available power.
5.1.2 System Grounding
Proper grounding is essential to ensure safe operation of the Inverter/Charger. Grounding requirements vary by country and
application. For specific requirements pertaining to your location and application, consult local codes and the NEC.

5.3.2
Connect the unit to the AC load. Then connect to the AC source. Confirm that all wiring is correct and terminals are tight.
5.3.3 Connecting Inverters for Parallel Operation
For parallel configuration of 3 APSX4048SW Inverter/Chargers, you will need to connect each Inverter/Charger through the ASNET
and PARALLEL STACKED INVERTERS ports located on the side of the units. All Inverter/Chargers should be powered off at this time.
Connecting Inverter/Charger 1 to Inverter/Charger 2: Connect the first Inverter/Charger to the second Inverter/Charger
through the units’ left-side ASNET terminals with 8P wire and RJ45 plugs. Then connect the right-side ASNET terminal of the
first Inverter/Charger with an 8P terminator resistor.
Next, connect the first and second Inverter/Charger’s PARALLED STACKED INVERTER ports. Using 6P wire and RJ45 plugs,
connect the left-side PARALLED STACKED INVERTER terminal on the first Inverter/Charger to the left-side PARALLED STACKED
INVERTER terminal on the second Inverter/Charger. Then connect the right-side PARALLED STACKED INVERTER terminal of the
first Inverter/Charger with a 6P terminator resistor.
5.3.4
Connecting Inverter/Charger 2 to Inverter/Charger 3: Now connect the second Inverter/Charger’s right-side ASNET terminal
to the third Inverter/Charger’s left-side ASNET terminal using 8P wire and RJ45 plugs. Then connect the right-side ASNET
terminal of third first Inverter/Charger with an 8P terminator resistor.
For the final step, connect the second and third Inverter/Charger’s PARALLED STACKED INVERTER ports. Again using 6P wire
and RJ45 plugs, connect the right-side PARALLED STACKED INVERTER terminal on the second Inverter/Charger to the left-
side PARALLED STACKED INVERTER terminal on the third Inverter/Charger. Then connect the right-side PARALLED STACKED
INVERTER terminal of the third Inverter/Charger with a 6P terminator resistor.

5. Inverter/Charger 3-Phase Parallel Installation
5.3.5
The Inverter/Chargers should now be installed and connected for 3-phase parallel operation. To enable 3-phase parallel
configuration on the Inverter/Chargers, go to section 6.4
Note: If the AC source power fails, the unit will work in Inverter mode. Otherwise the system will switch to AC Mode and will power the load while charging the
battery.
6. Operation
6.1 Modes of Operation (Single and 3-Phase)
The internal battery charger and automatic transfer relay allow the unit to operate as a battery charger, an inverter or a switch.
An external AC power source (e.g. utility or generator) must be connected to the Inverter’s AC input in order to allow it to
operate as a battery charger. When the unit is operating as a charger, AC loads are powered by the external AC power source.

6. Operation
6.3 Single-Phase Parallel Operation
6.3.1 Enabling Single-Phase Parallel Operation through Parameter Settings
Note: For more information on the Inverter/Charger’s general operation, review sections 6.1 and 6.2.
Once the batteries have been configured in series-parallel (see subsection 3.4.3) and the Inverter/Chargers have been
connected through the ASNET and PARALLEL STACKED INVERTER ports (see section 4.4), turn on the power to the first
Inverter/Charger. After the first Inverter/Charger has completed booting, the LCD will display the main status screen. From the
main status screen, go to the PARAMETER SELECTION page located in the Setting mode. Once inside the parameter settings,
set the PARALLEL ENABLE value to 1. The first Inverter/Charger will now be configured as master with an ID set to 32.
Proceed to power on all other connected Inverter/Chargers to enter standby mode. If the CANbus network established through
the PARALLEL STACKED INVERTERS connections is successful, the master Inverter/Charger will display ID32 in the LCD and
each connected slave Inverter/Charger unit will display a unique ID starting at 33, followed by 34, 35, and so on.
6.3.2 Auto Master Setting
When only one Inverter/Charger is powered on in a parallel system, it will display ‘CAN BUS NO RESPONSE’ on the unit’s
LCD. When another Inverter/Charger turns on through normal CAN BUS operation, the first Inverter/Charger powered will be
the master. If both Inverter/Chargers power at the same time, then the inverter with the smaller ID will become the master.
Because the system already has a master, even if a third inverter ID is smaller than the master, it could only be a slave.
Note: When the master fails or is offline, the slave inverter with the smallest ID will become the master.
6.3.3 Average Output Load
A slave will automatically switch from standby to the output based on a parallel system’s average load. When the total load is
over 1800W, the inverter that is in standby mode with the smallest ID will change to output mode. When the average load is
under 1350W, the inverter that is in output mode with the biggest ID will change to standby mode.
