IMPORTANT SAFETY INSTRUCTIONS
THIS MANUAL CONTAINS IMPORTANT INFORMATION REGARDING SAFETY, OPERATION,
MAINTENANCE AND STORAGE OF THIS PRODUCT. BEFORE USE, READ AND UNDERSTAND ALL
CAUTIONS, WARNINGS, INSTRUCTIONS AND PRODUCT LABELS, PLUS YOUR VEHICLE’S BATTERY
MANUFACTURER GUIDELINES. FAILURE TO DO SO COULD RESULT IN INJURY AND/OR PROPERTY
DAMAGE.
To ensure reliable service, your power inverter must be installed and used properly. Please read the installation
and operating instructions thoroughly prior to installation and use. Pay particular attention to the WARNING
and CAUTION statements in this manual. The CAUTION statements advise against certain conditions and
practices that may result in damage to your inverter. The WARNING statements identify conditions or practices
that may result in personal injury. Read All Instructions Before Using This Power Inverter!
WARNINGS
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, EXPLOSION OR INJURY
1. Do not connect to AC distribution wiring. This inverter is NOT grid interactive.
2. Remove appliance plug from outlet strip or turn off inverter before working on the appliance. Multiple
outlet power strips with switches and circuit breakers only interrupt power to the “hot” receptacle
terminals. For SSW-350-12A & SSW-600-12A, the “Neutral” terminals remain powered with respect to
the “Ground” terminals.
3. Do not make any electrical connections or disconnections in areas designated as IGNITION PROTECTED.
This includes 12 V DC cigarette plug connections, and terminal connections.
4. This is not a toy - keep away from children.
5. DO NOT install object into air vents.
CAUTIONS
1. The chassis and the input Negative terminal of the inverter are internally connected to the AC Ground.
Hence, the input Negative terminal should be used as the grounding terminal. Do not use with Positive
Grounded Electrical Systems (the majority of modern automobiles, RVs, trucks and boats are Negative
Grounded Electrical Systems).
2. Observe correct polarity when connecting the DC input terminals of the inverter to the battery. Connect
Positive of the battery to the Positive input connector of the inverter and the Negative of the battery to
the Negative input terminal of the inverter. Reverse polarity connection will result in a blown fuse and
may cause permanent damage to the inverter. Damage due to reverse polarity is not covered under
warranty.
3. This inverter will not operate high wattage appliances that exceed the output power limit or the surge
power limit.
4. For SSW-350-12A & SSW-600-12A, grounding the Neutral will cause the inverter to shut down. Hence,
do not connect the Neutral of the AC output receptacles to Ground.
5. Do not operate this inverter if it is wet.
6. Do not install in engine compartment – please install in a well ventilated area.
7. This inverter is not tested for use with medical devices.

IMPORTANT SAFETY INSTRUCTIONS
IMPORTANT WIRING INFORMATION
Substantial power loss and reduced battery operating time results from inverters installed with wires that are
not sized correctly based on the length and the current required to be carried. Current owing through a wire
produces voltage drop along its length due to the resistance of the wire and due to the value of the current
carried through it. The resistance of the wire is inversely proportional to the cross-sectional area of the wire
(designated in mm2 or AWG) and directly proportional to its length i.e. thinner and longer wire has higher
resistance and hence, produces higher voltage drop. Similarly, thicker and shorter wire has lower resistance and
hence, produces lower voltage drop. Hence, symptoms of low DC input voltage / battery power can result from
wires that are either excessively long or have an insufcient cross-sectional area (designated in mm2 or AWG).
The wires should be sized based on the maximum current they are required to carry and the distance between
the battery and the inverter to limit the voltage drop to 2% to 5%.
Wires are rated based on its insulation, temperature and operating environment. Please ensure that the wire
insulation is of the appropriate type for the operating environment.
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 wires and appliance wiring.

HOW YOUR INVERTER WORKS
The inverter converts low voltage DC (Direct Current) from a battery or other DC power source to the standard
nominal 115 volt AC (Alternating Current) household power.
DESIGN FEATURES
• High efciency
• Compact size
• Low Idle current
• Soft Start Technology
• LCD Remote Control (for 1000 W, 1500 W & 2000 W models).
POWER RATINGS
The continuous power ratings of the models are as follows:
• SSW-350-12A - 350 Watts
• SSW-600-12A - 600 Watts
• SSW-1000-12A - 1000 Watts
• SSW-1500-12A - 1500 Watts
• SSW-2000-12A - 2000 Watts
PRINCIPLE OF OPERATION
The inverter converts power in two stages. The rst stage is a DC to DC conversion process that raises the
low voltage DC at the inverter input to high voltage DC of approximately 150 VDC. The second stage is the
actual inverter stage that converts the high voltage DC into nominal 115 VAC, 60 Hz AC (RMS). The DC-to-
DC converter stage uses modern high frequency power conversion techniques that have replaced the bulky
transformers found in less technologically-advanced models. The inverter stage uses advanced power MOSFET
transistors in a high frequency full bridge conguration.
THE OUTPUT WAVEFORM
The AC output waveform of the SSW-series inverter is known as “Pure Sine Wave” or “True Sine Wave”. It is a
waveform that has characteristics same to the sine wave shape of utility power (See Fig. 1).

INSTALLATION / ENVIRONMENTS
DC POWER SOURCE REQUIREMENTS
The DC power source must provide between 10.5 and 15.5 Volts DC and must be able to supply the necessary
current to operate the load. The power source may be a battery or a well-regulated DC power supply. To
obtain a rough estimate of the current (in Amperes) the power source must deliver, simply divide the power
consumption of the load (in Watts AC) by 10.
Example: if a load is rated at 100 Watts AC, the DC power source must be able to deliver: 100 / 10 = 10A.
The inverter will provide you nominal 115 VAC when powered by a 12 VDC source such as is found in a vehicle
or multiple battery congurations as shown in Fig. 2. This manual does not describe all of the possible types of
battery congurations, battery charging congurations and battery isolation congurations.
For normal operation of the inverter, the DC power source must provide between 11.0 and 15.0 VDC and the
required current. This DC power source must be a well-regulated DC power supply or alternator and deep
cycle battery system typically found in vehicles and marine crafts. The DC power source may also be two or
more 12 volt batteries connected in parallel. On larger applications, the power source may be several batteries
connected in parallel as shown in Fig. 2.

INSTALLATION NOTES
WARNING: Ensure ventilation when using batteries. Batteries may generate ammable gas during
charging or discharging.
The inverter (350 W to 2000 W models) has four slots in its mounting bracket that allow the unit to be fastened
against a bulkhead, oor, wall or other at surface. Ideally, the mounting surface should be cool to the touch.
It is more electrically efcient to use longer AC wiring than DC wiring, so install the inverter as close as
possible to the 12 VDC power source.

INSTALLATION / ENVIRONMENTS
The inverter can be operated in any position, however, if it is to be mounted on a wall, mount it horizontally
(Fig 3a) so that indicators, switches, outlets and terminal blocks located on the front panel are visible and
accessible. Do not mount on wall in positions shown in Figs. 3 (b) & 3(c). If the inverter is to be installed in a
moving vehicle, we strongly recommend that the inverter be shock-mounted either on the oor (in a clear, safe
area) or on a secure at surface
(Fig 3a)
(a) (c)(b)
Fig. 3 Mounting arrangement on wall
CAUTION
The power inverter must be connected only to batteries with a nominal output voltage of 12 V. The unit will
not operate from a 6 Volt battery, and will sustain permanent damage if connected to a 24 V battery.
CAUTION
Loose connectors may cause overheated wires and melted insulation. Check to make sure you have not
reversed the polarity. Reverse polarity connection will result in a blown fuse and may cause permanent damage
to the inverter. Damage due to reverse polarity is not covered by warranty.
CONNECTING TO A DC POWER SOURCE
Please ensure that the DC side wires and external fuses are selected as given below.
Note that an external fuse is required to protect the battery wires from short circuit. A battery is an unlimited
source of current and can deliver extremely high (up to 10,000 A of current) into a short circuit that will melt
the wires and cause re hazard.
Current limiting fuse with Ampere Interrupting Capacity (AIC) of 10000 A or more or Class T fuse is, therefore,
recommended.

The inverter is engineered to be connected directly to standard electrical and electronic equipment in the
manner described above. Do not connect the power inverter to household or RV AC distribution wiring. Do
not connect the power inverter to any AC load circuit in which the Neutral conductor is connected to Ground
(Earth) or to the Negative of the DC (battery) source.
WARNING: Do not connect directly to AC distribution wiring. This inverter is NOT grid interactive.
OPERATING ENVIRONMENT
For best operating results, the inverter should be placed on at surface, such as the ground, car oor, or other
solid surface. The power cord allows easy positioning of the inverter. The inverter should only be used in
locations that meet the following criteria:
DRY
Do not allow water and/or other liquids to come into contact with the power inverter. In all marine
applications, do not install the inverter below or near the waterline and keep the inverter away from moisture
or water.
COOL
Ambient air temperature should be between 30 degrees F (-1 degree C) non-condensing, and 105 degrees F (40
degrees C). Do not place the inverter on or near a heating vent or any piece of equipment which is generating
heat above room temperature. Keep the inverter away from direct sunlight, if at all possible.
VENTILATED
The unit is cooled by load controlled fan (s). The fan(s) will be normally switched off at low loads to conserve
battery power and will be switched on automatically once the load reaches a certain threshold. Keep the area
surrounding the inverter clear to ensure free air circulation around the unit. Do not place items on or over
the inverter during operation. An additional external fan is helpful if the inverter is operating at maximum
power outputs for extended periods of time. The unit will shut down if the internal temperature exceeds the
operating temperatures. The unit will restart after it cools.
SAFE
Do not use the inverter near ammable materials or in any locations that may accumulate ammable fumes of
gases.

OPERATING TIPS
RATED VERSUS ACTUAL CURRENT DRAW OF EQUIPMENT
Most electrical tools, appliances and audio/video equipment have labels that indicate the power consumption
in Amps or Watts. Be sure that the power consumption of the item you wish to operate is less than inverter’s
power. (If the power consumption is rated in Amps AC, simply multiply by the AC Volts (115) to determine the
approximate Wattage). The inverter will shut down if it is overloaded. The overload must be removed before
the inverter will restart. Resistive loads are the easiest for the inverter to run. However, larger resistive loads,
such as electric stoves or heaters, usually require more wattage than the inverter can deliver. Inductive loads,
such as TV’s and stereos, require more current to operate than do resistive loads of the same wattage rating.
Induction motors, as well as some televisions, may require 2 to 6 times their wattage rating to start up. The
most demanding in this category are those that start under load, such as compressors and pumps. To restart the
unit after a shutdown due to overloading, remove the overload if necessary turn the power switch OFF, wait
for at least 3 minutes and then switch ON again.
SIZING CHART FOR TYPICAL LOADS THAT REQUIRE HIGH STARTING SURGE
The manufacturers’ specications of the appliances and devices indicate only the running power required.
The surge power required by some specic types of devices has to be checked with the manufacturer, actually
tested or guessed at best.
The Table below lists some common loads that require high surge power on start up. A “Sizing Factor” has
been recommended against each which is a Multiplication Factor to be applied to the rated running Watt
rating of the load to arrive at the continuous power rating of the inverter (Multiply the running Watts of the
device / appliance by the Sizing Factor).

Refrigerator / Freezer (Compressor based) 5
Air Compressor 4
Sump Pump / Well Pump / Submersible Pump 3
