ensure optimum performance and to avoid damage to this product.

4
This power inverter is configured to supply continuous power in the form of 120 volt AC outlets and a USB port to
run or recharge most household or electronic appliances.
FEATURES
The front Display, indicates power and proper operation of the inverter. This also displays inverter fault codes, if the
inverter happens to shut down from over-load or over-temperature condition, or abnormal input voltages. The ON/
OFF Switch turns the inverter ON and OFF. The switch can also be used to force reset of inverter circuits by
switching it OFF, then back ON again. All models also feature a port to attach a remote control (sold separately).
120 volt AC power is supplied through two North American three-prong type outlets. The outlets can accommodate
either two- or three-pin AC plugs.
Controls and Functions
FRONT OF UNIT (ALL UNITS)
The Protection Switch is a circuit breaker. If the output is exceeded, the breaker will POP and you will have to
manually reset it.This circuit breaker will protect the inverter in case of Overload or short circuit. If you have to
reset this breaker, you should verify the Startup and Running current requirements for you equipment. Startup
may be several times higher than the running rate. and may cause this protection breaker to pop. Example: air
conditioners or air compressors have high startup ratings called Locked Rotor Amps tL.R.A.)

BACK OF UNIT (ALL UNITS)
HOW THESE INVERTERS WORK
Your inverter converts low voltage DC (direct current) electricity from a battery to 115 volt AC (alternating current)
household power in two stages. The first stage is a DC-to-DC conversion process that raises the low voltage DC
at the inverter input to 145 volts DC. The second stage converts the high voltage DC into 115 volts, 60 Hz AC.
Power Inverter Output Waveform
The AC output waveform of your inverter is known as a pure sine wave. It is a stepped waveform that has
characteristics similar to the sine wave shape of utility power. This type of waveform is suitable for most AC loads,
including linear and switching power supplies used in electronic equipment, transformers and small motors.
The pure sine wave produced by this inverter has an RMS (root mean square) voltage of 115 volts. Most AC
voltmeters (both digital and analog) are sensitive to the average value of the waveform rather than the RMS value.
They are calibrated for RMS voltage under the assumption that the waveform measured will be a pure sine wave.
These meters will not correctly read the RMS voltage of a pure sine wave. Non-TRUE RMS meters will read about
20 to 30 volts low when measuring the output of this inverter. For accurate measurement of the output voltage of
this unit, use a TRUE RMS reading voltmeter such as a Fluke 87, Fluke 8080A, Beckman 4410 or Triplett 4200.
115 VOLT AC OUTPUT
CAUTIONS
Ensure that total continuous power consumption of all tools and appliances to be used simultaneously with your
inverter does not exceed the inverter’s continuous wattage rating. Also ensure that start-up wattage for inductive
loads does not exceed peak watts for more than a second.
Appliances such as microwave ovens will normally draw more than their rated current and could possibly overload
the inverter when operated simultaneously with other appliances. For example: A 600 watt microwave oven draws
approximately 940 watts.

Rechargeable Devices
CAUTIONS
• Some rechargeable devices are designed to be charged by plugging them directly into an AC receptacle. These
devices may damage the inverter or the charging circuit.
• When using a rechargeable device with your inverter, monitor its temperature for the initial ten minutes of use to
determine if it produces excessive heat. If excessive heat is produced, the device should not be used with your
inverter.
• This problem does not occur with most battery-operated appliances and tools. Most of these appliances use a
separate charger or transformer that is plugged into an AC receptacle.
• Your inverter is capable of running most chargers and transformers.
POWER SOURCE AND PROTECTIVE FEATURES
Power Source Requirements
Your inverter will operate from input voltages between 10-17 Volts DC. If the voltage drops below 10 volts, an
audible low battery warning alarm will sound. If the input voltage drops below 10 volts DC, the inverter will shut
down. This feature protects the battery from being completely discharged.
The inverter will also shut down if the input voltage exceeds 17 volts. This protects the inverter against excessive
input voltage. Although the inverter has built-in protection against over voltage, it may still be damaged if the input
voltage exceeds 17 volts.
Your inverter is engineered to be connected directly to standard electrical and electronic equipment in the manner
described in the “Installation” section of this Instruction Manual. Do not connect the inverter to household or RV AC
distribution wiring. Do not connect the inverter to any AC load circuit in which the neutral conductor is connected to
ground (earth) or to the negative of the DC (battery) power source.
The inverter will operate most AC loads within its power rating. Some induction motors used in refrigerators,
freezers, pumps and other motor-operated equipment, require very high surge currents to start them. The inverter
may not be able to start some of these motors even though their rated current draw is within specifications for this
power inverter. If a motor refuses to start, observe the battery voltage using a DC voltmeter while trying to start the
motor. If the battery voltmeter drops below 11 volts while the inverter is attempting to start the motor, this may be
why the motor won’t start. Make sure the battery connections are tight and the battery (or batteries) is (are) fully-
charged. If the connections are good and the battery is charged, but the voltage still drops below 11 volts, you may
need to use a larger battery (or battery combination).
Inductive loads, such as TVs and stereos, require more current to operate than resistive loads of the same wattage
rating. Induction motors, as well as some TVs, may require two to six times their rated wattage to start up. Because
these inverters have a peak watt power rating, many such appliances and tools may be safely operated. The
equipment that needs the highest starting wattage are pumps and compressors that start under load. This
equipment can be safely tested. If an overload is detected, the inverter will simply shut down until the overload
situation is corrected.
CAUTIONS
• Exceeding recommended voltage limits will void manufacturer’s warranty.
• NEVER try to use your inverter with any 12 volt DC power source that uses a positive ground. (Most vehicles and
boats use negative ground systems.)
• The Power Inverter must be connected only to batteries with a nominal output voltage of 12 volts. The unit will not
operate from a 6 volt battery and will sustain permanent damage if connected to a 24 volt battery.
• Reverse polarity connection will result in a blown fuse and may cause permanent damage to the inverter.
Determining Battery Size
To determine the minimum battery size you will need to operate appliances from your inverter, follow these steps:
1. Determine the wattage of each appliance and/or tool you will need to simultaneously operate from the inverter.
To do this, read the labels on the equipment to be operated.
2. Estimate the number of hours the equipment will be in use between battery recharges.
3. Determine the total watt-hours of energy use, the total running time and the average power consumption.
Keep in mind that some appliances are not drawing the same power continuously. For example, a typical home-use
coffee maker draws 850W / 1000W during brew time (approx. 5 minutes) but maintains the pot temperature at only
about 100 watts. Typical use of a microwave is only for a few minutes, sometimes at low power.

7
Protective Features
The inverter has electronic circuit protection against overload and short circuit conditions; and monitors for the
following potentially hazardous conditions:
Low Battery Voltage —This condition is not harmful to the inverter, but could damage the power source. An alarm
will sound when input voltage drops below 10.5 volts, and the inverter will automatically shut down when input
voltage drops below 10.0 volts. This indicates that the DC (battery) power source needs to be charged, or there is
an excessive voltage drop between the battery power source and the inverter. When the condition is corrected, the
inverter will automatically restart.
Over Voltage Protection — The inverter will automatically shutdown when input voltage exceeds 16 volts DC.
Overload Protection — The unit will automatically shut down when the continuous draw exceeds the inverter’s
wattage rating. Reduce the load and manually restart.
Over Temperature Protection — If the temperature inside the inverter reaches 150°F, the unit will automatically
shut down. Allow the inverter to cool for at least 15 minutes before restarting after a heat-related shutdown. Unplug
the inverter from the power source and disconnect all appliances or tools from the inverter’s outlets while cooling.
If the Digital display, displays a fault code follow the steps outlined in the “Troubleshooting” section of this Instruction
Manual. The Fault LED will light if there is an excessive voltage drop between the (battery) power source and the
inverter.
Note: Reverse polarity or short circuit condition may cause external or internal fuses to open and may cause irreversible
damage to the Power Inverter. Take extra care to ensure a proper polarity hook-up.
CAUTION
• If turning the ON/OFF Switch off, then on again does not reset the inverter, DO NOT ATTEMPT TO OPEN THE
INVERTER. Opening the inverter for any reason will void the warranty. The unit must be returned to manufacturer
for testing and repair by professional factory technicians.
INSTALLATION
Your inverter will provide you with continuous electrical power when powered by a reliable 12 volt DC source, such
as a vehicle battery or a multiple battery configuration. This manual does not describe all of the possible
configurations.
Operating Environment
For best operating results, your inverter should be placed on a flat surface, such as the ground, car floor or seat or
other solid surface to help diffuse the heat that is generated. Position the inverter as close to the DC power source
as possible.
The inverter should only be operated in locations that meet the following criteria:
DRY – Do not allow water and/or other liquids to come into contact with the inverter.
COOL – Ambient air temperature should be between 30°F (–1°C) non-condensing and 105°F (40°C). Do not place
the inverter on or near a heating vent or any piece of equipment that is generating heat above room temperature.
Keep the inverter out of direct sunlight.
VENTILATED – Allow at least three inches of clearance from other objects to ensure free air circulation around the
inverter. Never place items on or over the inverter during operation.
SAFE – Do not locate inverters in an area, room or compartment where explosives or flammable fumes might be
present, such as engine rooms, engine compartments and boats or small, un-vented battery compartments.
Quick Operational Test or Emergency Use
You will need:
• A heavy-duty jumper cable set of the specified AWG wire rating
• A fully-charged automobile battery
• A common slip joint plier for loosening and tightening terminal nuts

8
PROCEDURE
1. Unscrew nuts in input terminal block.
2. Identify the positive and negative terminals on the 12 volt DC battery (or other 12 volt DC power source) and
identify the positive and negative terminals on the inverter.
3. Using a set of heavy-duty jumper cables, attach the red cable to the inverter’s positive (+) terminal and the black
cable to the inverter’s negative (–) terminal.
4. Connect the clamps on the other ends of the jumper cables to the corresponding positive (+) and negative (–)
terminals on the 12 volt DC vehicle battery (or other 12 volt DC power source). There may be some minor
sparking.
5. Turn the inverter ON/OFF Switch on.
6. Plug in a lamp with a 100 watt light bulb and switch the lamp on. If the lamp works normally, the inverter is
functioning properly and you can proceed to a permanent installation or continue to use the inverter with low
wattage appliances. If the lamp does not light or does not work correctly:
A. Check all connections and tighten any that may be loose.
B. Ensure that the source battery has adequate charge.
C. If steps A and B do not correct the problem, refer to the “Service Information” section of this Instruction
Manual for assistance.
Permanent Installation (Refer to THOR inverter Install kits at www.thorpowerproducts.com)
For permanent installation to heavy-duty battery power you will need:
• Terminals to fit cable ends and stud terminals to inverter
• Hardware and battery connector to connect cables to the battery bank
• A single length of AWG cable multi-stranded, flexible, insulated cable for chassis ground connection when using
inverter in a household application.
• A holder and fuse.
• Mounting screws, bolts and nuts for mounting the inverter and fuse holder
• A drill for mounting the inverter and fuse holder
• Lead-tin solder, flux, propane torch and an igniter for the torch
• Wire stripper/cutting tool
PRELIMINARY STEPS
The inverter has four slots in its mounting bracket that allow the unit to be fastened against a bulkhead, floor, wall
or other flat surface. Ideally, the mounting surface should be cool to the touch. It is more efficient to use longer AC
wiring than DC wiring, so install the inverter as close as possible to the 12 volt DC power source.
The inverter should be operated in horizontal position; if it is to be mounted on a wall, mount it horizontally so that
indicators, switches, outlets and terminal blocks on the front panel are visible and accessible.
1. If inverter is to be installed in a vehicle, manufacturer recommends that it be shock mounted to either the floor
(in a clear, safe area) or on a secure flat surface.
2. Locate a convenient place to mount the inverter and fuse holder.
3. Perform a test routing of the proposed cable length, but don’t do any cutting at this time (refer to the diagram
in the “Battery Configuration” section of this Instruction Manual).
4. Using an appropriate AWG cable, reposition the inverter and fuse holder if necessary.
5. After you have performed the above preliminary installation steps, proceed with the actual inverter installation.
Contact the manufacturer for any further installation information or questions.
PERMANENT INSTALLATION PROCEDURE
The cables between the power source and inverter should be set up as illustrated in the diagram in the “Battery
Configuration” section of this Instruction Manual. Unscrew terminal nuts before beginning permanent installation.
Proceed with DC cable and fuse installation as follows:
1. Ensure the inverter’s ON/OFF Power Switch is in the off position.
2. Using tools and hardware, mount the inverter to a flat, stable surface.
3. Ensure that mounting hardware does not touch any fuse holder or fuse contacts. Select an appropriate fuse
and ensure that the fuse is removed from its holder.
4. Select appropriate cable. Measure the cable twice before cutting.
5. Cut one cable length to connect the negative (–) battery terminal to the inverter’s negative terminal, leaving a
little slack in the cable.

9
6. Cut another cable to connect the positive (+) battery terminal to one side of fuse holder, leaving a little slack.
7. Cut the final cable to connect the other side of fuse holder to the inverter’s positive (+) terminal.
8. Strip the end insulation of all three cables to 1-inch (2.45 cm).
9. Sweat-solder end of all cables. For safety, do this in an open space because it may require the use of a propane
torch.
10. Connect one end of the negative (–) cable to a ring terminal* going to the battery(ies).
11. Connect the short end of the positive (+) cable to a ring terminal* going to the battery(ies).
12. Crimp or clamp ring terminals of the negative (–) and positive (+) cables (going to the battery), but do not
connect to the battery yet.
13. Connect the stripped, soldered (longer) end of the positive (+) cable to the red stud marked (+) on the inverter
and tighten the retaining nut.
14. Connect the stripped, soldered end of the negative (–) cable to the black stud marked (–) on the inverter and
tighten the retaining nut.
15. Connect the other (long) end of the (+) positive cable to one terminal of the heavy-duty fuse holder.
16. Connect the other conductor of the heavy-duty fuse holder to the (short) positive (+) battery terminal.
17. Connect the other end of the (–) negative cable with the ring terminal to the negative (–) battery terminal.
18. Connect an appropriate insulated wire between the chassis grounding screw on the inverter’s case and a solid
electrical ground to minimize possible electrical noise in TV and radio reception. Do not connect this wire to the
negative DC input terminal.
19. Ensure that all electrical connections have been tightened.
20. Insert the fuse into the fuse holder. There may be some sparking.
21. Ensure the 12 volt DC power source has an adequate charge.
22. Turn the inverter on and apply a test load to the 120 volt AC outlets.
* Ring terminals are not included and must be supplied by user.
If, after following all of the above steps, the inverter does not perform properly, the source voltage may be too low
or the cables may be too long (or the gauge too light). Having checked and corrected these conditions, if necessary,
refer to the “Service Information” section of this Instruction Manual for assistance if problems persist.
CAUTION
• Loose connectors may cause overheated wires and melted insulation.
• Check to make sure you have not reversed the polarity. Damage due to reversed polarity is not covered by
manufacturer’s warranty.
IMPORTANT CABLE INFORMATION:
Substantial power loss and reduced battery operating time results from inverters installed with cables that are not
able to supply full power. Symptoms of low battery power can result from cables that are either excessively long or
an insufficient gauge. Marine installations are also subjected to vibration and stresses that exceed those of other
mobile installations. Therefore, the installer/operator should be especially aware of the requirements to maintain
secure, tight, water-resistant electrical connections and to provide for strain relief for DC cables and appliance
wiring. Cable insulation must be the appropriate type for the environment.

10
CONNECTING THE AC WIRING
AC connections are made on the terminal block located inside the front panel of the inverter.
To connect AC wiring:
1. Disconnect the inverter from the battery.
2. Remove the AC wiring compartment cover.
3. Feed the wires through inverter’s case.
4. Following the wiring guide located in the AC wiring compartment, connect the Line (black) and Neutral (white
wires to the terminal block and tighten securely. The safety (green) wire is connected to the ground screw
terminal.
5. Replace the AC wiring compartment cover.
AC Wiring Safety Precautions
Preventing Paralleling of the AC Output the AC output of the unit should never be connected directly to an Electrical
Breaker Panel / Load Centre which is also fed from the utility power / generator. Such a direct connection may result
in parallel operation of the different power sources and AC power from the utility / generator will be fed back into
the unit which will instantly damage the output section of the unit and may also pose a fire and safety hazard. If an
Electrical Breaker Panel / Load Center is fed from this unit and this panel is also required to be fed from additional
alternate AC sources, the AC power from all the AC sources (like the utility / generator / this inverter) should first
be fed to an Automatic / Manual Selector Switch and the output of the Selector Switch should be connected to the
Electrical Breaker Panel / Load Center., THOR Manufacturing’s Automatic Transfer Switch Model THTS Series is
recommended for this application.
Hard Wiring of AC Output to AC Panel boards in RVs / Motor Homes / Trailers /Campers WARNING! RISK OF
ELECTRIC SHOCK When this unit is installed in RV / Motor Homes / Trailers / Campers and hard wiring connection
is used to feed the AC output of the inverter to the AC Distribution Panel board / Load Center in the vehicle, it is to
be ensured that Ground Fault Circuit Interrupter(s) [GFCI] are installed in the vehicle wiring system to protect
branch circuits.
EMI and FCC COMPLIANCE These inverters contain internal switching devices that generate conducted and
radiated electromagnetic interference (EMI). The EMI is unintentional and cannot be entirely eliminated. The
magnitude of EMI is, however, limited by circuit design to acceptable levels as per limits laid down in North
American FCC Standard FCC Part 15(B), Class A. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in business / commercial / industrial environments.
THPW1000 - 1500 THPW2000 - 3000

11
These inverters can conduct and radiate radio frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio communications.
REDUCING EMI THROUGH PROPER INSTALLATION The effects of EMI will also depend upon a number of
factors external to the inverter like proximity of the inverter to the EMI receptors, types and quality of connecting
wires and cables etc. EMI due to factors external to the inverter may be reduced as follows: - Ensure that the
inverter is firmly grounded to the ground system of the building or the vehicle - Locate the inverter as far away from
the EMI receptors like radio, audio and video devices as possible - Keep the DC side wires between the battery
and the inverter as short as possible. - Do NOT keep the battery wires far apart. Keep them taped together to
reduce their inductance and induced voltages. This reduces ripple in the battery wires and improves performance
and efficiency. - Shield the DC side wires with metal sheathing / copper foil / braiding: - Use coaxial shielded cable
for all antenna inputs (instead of 300 ohm twin leads) - Use high quality shielded cables to attach audio and video
devices to one another - Limit operation of other high power loads when operating audio / video equipment
CAUTION. Each of the NEMA5-15P outlets is rated for 16A continuous and 20A intermittent. Do not draw more
than this rating from each outlet. For drawing the full rated output capacity of 25A of the inverter, use AC output
connections for hard wiring (13, Fig 6.1b) as described at Section 8.5.2 below. 2. Do not feed the output from the
GFCI receptacle to a Panel board / Load Center where the Neutral is bonded to the Earth Ground. This will trip the
GFCI. If the AC output is required to be fed to a Panel board / Load Center, use hard wiring connections. 3. If an
extension cord is used from the GFCI outlet, please ensure that the cord is suitable for the rated load and provided
with grounding.
AC Output Connections for Hard wiring For connecting the AC output of the inverter to an AC Panel board / Load
Center, separate connections are available for hard wiring Compartment contains terminals for AC output. The
compartment is covered by Cover Plate with the help of 4 screws. The AC wiring enters through the Strain Relief
Clamp . After the connections have been made, tighten the clamp. AC output connections are as follows: Terminal
Block with Line “L” and Neutral “N” Terminals. Please note that Line terminal “L” of the AC Terminal Block and the
Line terminal on the Line side of the GFCI are internally connected together at the PCB. Similarly, Neutral terminal
“N” on the AC Terminal Block and the Neutral terminal on the Line side of the GFCI are internally connected together
at the PCB. All external wiring should be in accordance with NFPA 70 / NEC and local wiring codes.
Grounding to Earth or to other Designated Ground For safety, ground the metal chassis of the inverter to the Earth
Ground or to the other designated ground (For example, in a mobile RV, the metal frame of the RV is normally
designated as the Negative DC Ground). A chassis Grounding Lug (19, Fig 6.1c) has been provided for grounding
the metal chassis of the inverter to the appropriate ground. When using the inverter in a building, connect a 10 mm2
or AWG #8 insulated stranded copper wire from the above equipment grounding lug to the Earth Ground connection
( a connection that connects to the Ground Rod or to buried metallic water pipe or to another connection that is
solidly bonded to the Earth Ground ). The connections must be tight against bare metal. Use star washers to
penetrate paint and corrosion. When using the inverter in a mobile RV, connect a 10 mm2 or AWG #8 insulated

compartment, Overheating may result.
OPERATING INSTRUCTIONS
CAUTION: Make sure the combined load requirement of your equipment does not exceed your inverter’s
maximum continuous power.
Operation of the 120 Volt AC Outlets
This unit features 115 volt AC GFCI (ground fault circuit interrupter) protected outlets, that function in the same way
as GFCI outlets you would typically use in your home. GFCI outlets are intended to protect equipment by
interrupting the circuit if current leakage exceeds 30 mA of current within 25 milliseconds.
1. Connect the inverter to a functioning 12 volt DC power source as described in this Instruction Manual. Make
sure there is adequate space for proper ventilation of the inverter.
2. Press the Power Push button to turn the unit ON.

Notes on Using the Remote Control (sold separately)
The manufacturer offers (as a separate item) a Remote Control specifically designed for this line of inverters. The
inverter On/Off Switch must be in the off position when connecting the Remote Control to the unit, or the Remote
Control will not operate. Once the unit has been turned on using the Remote Control, inverter operation will continue
to be controlled through the Remote Control. Turn the inverter off before disconnecting the Remote Control. For more
information about attaching and using the Remote Control, please refer to the Remote Control Instruction Manual.
TROUBLESHOOTING GUIDE
Common Audio/Visual Problems
PROBLEM SOLUTION
“Buzzing” sound in
audio systems
Inexpensive stereo systems and “boom boxes” may emit a buzzing sound from their
speakers when operated from your inverter. This occurs because the power supply in
the electronic device does not adequately filter the pure sine wave produced by the
inverter. The only solution to this problem is to use a higher quality sound system.
Television
Interference
Your inverter is shielded to minimize interference with TV signals. However, in some
instances, some interference may still occur, particularly where TV signals are weak.
Try the following corrective measures:
• Place the inverter as far as possible from the television. Use an extension cable, if
necessary.
• Readjust the orientation of the inverter, the antenna cables and the TV power cord to
minimize interference.
• Make sure the antenna feeding the television provides an adequate (“snow free”)
signal and that high quality, shielded antenna cable is used.
• Do not use the inverter to operate high-power appliances or tools at the same time
you are using it to operate the TV.
• Make sure the inverter’s case is properly grounded (refer to the “Permanent
Installation Procedure” section of this Instruction Manual).
