INTRODUCTION
The AIMS Power pure sine inverter product line is used for back-up or mobile
power. The pure sine product line is ideal for sensitive equipment and provides
clean power, which is more efficient for back-up power applications. The power
inverter transforms DC (direct current) electricity into AC (alternating current) power
that can be used for running a wide variety of small devices, up to 5 amps using a
battery. This inverter is perfect for providing mobile power in vehicles, RVs, boats,
vans or buses.
Read this instruction manual carefully and make sure your inverter is installed
properly before using.
WARNING AND SAFETY
1. Keep manual for future reference.
2. Do not put the inverter under direct sunlight or near a heating source.
3. The case of the inverter will get hot when used. Do not allow flammable materials
to contact the inverter, such as clothing, sleeping bags, carpet or any other
flammable materials. The heat from the inverter can damage these items.
4. The power inverter is designed to be used with a negative ground electrical
system! Don't use with positive ground electrical systems (the majority of modern
automobiles, RVs, trucks and boats are negative ground).
5. Do not disassemble the unit: it may cause fire or electric shock.
6. This device should only be serviced by a qualified technician. This item does not
have any serviceable parts.
7. Prevent body contact with grounded surfaces such as pipes, radiators, ranges,
and refrigerator enclosures during installation.
8. Do not operate the inverter if under the influence of alcohol or drugs. Read
warning labels on prescriptions to determine if your judgment or reflexes are
impaired while taking drugs. If there is any doubt, do not operate the inverter.
9. People with pacemakers should consult their physician(s) before using this
product. Electromagnetic fields in close proximity to a pacemaker could cause
interference to or failure of the pacemaker.
10. Keep the inverter well-ventilated. Do not place any objects on top of or next to the
inverter or allow anything to cover the cooling fans; doing so can cause the
inverter to overheat, causing a potential fire hazard and/or damage to the inverter.
Leave adequate ventilation space underneath the inverter as well; thick carpets or
rugs can obstruct air flow, causing the inverter to overheat.
11. Avoid unintentional starting. Be sure the switch is in the OFF position when not in
use and before plugging in any appliance.
12.Keep inverter away from children. Don't install the inverter where it is accessible
2

INSTALLATION
Ensure there is enough space for the installation, and the location should meet the
following requirements:
1. Water should not access the inverter.
2. The ambient temperature should be 32~104°F, and the preferred temperature is
50-77°F. The lower the better in this range of ambient temperature.
3. Do not mount the inverter upside down.
3

4. We recommend mounting the inverter on something stable to prevent it from
bouncing. Impact shock could result in damage to your unit. Be sure to use all
four mounting screws for optimal stability. Mount in a location that can support
the weight of the inverter.
5. Allow 12 inches of space around the inverter to prevent objects from blocking the
vents and to provide enough air to circulate.
6. Do not install the inverter in an environment with high dust, saw dust residue or
other particles that may get sucked into the inverter increasing internal
temperature.
7. There will be some electrical arcing or spark when the inverter connects with the
battery. Combustible materials such as gasoline, alcohol, etc. should not be
around the inverter.
BATTERY
1. The battery is designed to supply the inverter with DC input voltage and the rated
voltage should be in accordance with the rated input voltage of the inverter. Any
voltage exceeding the range of the input voltage of the inverter will cause the
inverter to go into overload and could possibly damage the inverter. The battery
should supply enough current for the load. The load is the amp or watt rating of
the equipment being powered by the inverter. A small capacity battery cannot
provide enough power for large electrical equipment. In this case, the battery will
cause the inverter to go into under voltage protection because of the load put on
the battery. A simple way to calculate the load or amps required from your battery
is to divide watts of equipment by battery voltage. Due to the consumption of the
inverter itself, the actual current will be about 10% more. For example, the voltage
of lead acid battery is 12VDC, and load of the equipment is 1000W, therefore, the
actual current needed from the battery is about 1000W / 12V = 83.3 amps per
hour. Add 10% for efficiency loss and you get 83.3 * 1.10% = 91.6 amp per hour
needed. If you don’t know the wattage of your equipment, you can figure the
wattage by multiplying AC amps by AC voltage. For example, a refrigerator is 8
AC amps * 120 Volts AC = 960 watts. Remember, all equipment has a start-up
requirement 3-5x its running wattage. In this example, 960 watts * 3 = 2880 watts
needed from the inverter so don’t size your inverter too small.
2. Battery operating time depends on battery capacity and load. The formula for
operating time is: battery capacity divided by the value of the load divided by
battery voltage times 1.10%. For example, using the numbers from above, the
battery specification is 12V, 200Ah capacity and the load is 1000W. Take battery
capacity 200Ah / 91.6 amps = 2.18 hours of run time if you fully deplete the
battery. This is NOT recommended. Deep cycle batteries last longer when they
are only depleted to 50% of capacity.

CONNECTION
1. Grounding
The power inverter has a terminal on the rear panel marked " Grounding "or "≡".
This is used to connect the chassis of the power inverter to ground. The ground
terminal has already been connected to the ground wire of the AC output
receptacle through the inverter.
The ground terminal must be connected to the ground wire, which will vary
depending on where the power inverter is installed. In a vehicle, connect the
ground terminal to the chassis of the vehicle. In a boat, connect it to the boat’s
ground system. In a fixed location, connect the ground terminal to earth.
2. Battery terminals
Before you connect the battery cables, make sure the power switch is in the off
position. Connect Red (+) battery cable to Red (+) inverter terminal. Connect
Black (-) battery cable to Black (-) inverter terminal. Connect Red (+) battery cable
to Red (+) battery terminal. Connect Black (-) battery cable to Black (-) battery
terminal. Alligator clamp cables may be used but only to connect to the battery.
Do not use clamps on inverter terminals. Alligator clamps are not a permanent
solution. You may see a spark during connection. Do not reverse the polarity.
This may damage the inverter and void warranty.
3. If connecting to a breaker panel do NOT neutral ground bond the panel.
USING THE POWER INVERTER
1. Check the output voltage and capacity of the battery. The battery (s) should
match the voltage of the inverter and have enough capacity for the load. See
Section E for more information.
2. Connect your inverter to your battery bank and do not to reverse the polarities of
the connection. See Section F.
3. Press the power switch button on your inverter for .5 seconds and a green LED
will light up indicating that the inverter is on.
4. Before plugging anything into your inverter, make sure the appliance you are
trying to power is shut OFF, then plug it into the AC outlet of your inverter and
power on your appliance. If powering an inductive load, see Soft Start section.
5. Once finished using the inverter, turn off your electrical appliance and the
inverter. The indicator lights should be off.
6. The cooling fans inside the inverter do not work until the case temperature
reaches approximately 104°F.
7. If you do not plan to use the inverter for a long period of time, disconnect it from
your battery bank. Leaving the inverter on and connected for long periods of
time may harm the equipment and over discharge the battery.
8. The USB port on this unit can provide a stable line of 5V DC current. The 5
maximum current is 1000 mA. Be sure to double check your device to make sure
it doesn't exceed these requirements.

SOFT START TECHNOLOGY
The soft start technology built into this inverter protects the unit from delivering too
much AC power at once by gradually increasing the AC voltage pushed out. To
make sure that you are utilizing this feature, turn on the appliance being used
before turning on the inverter. This is especially necessary for equipment that has
an inductive load or electrical motor.
OUTPUT VOLTAGE & WAVEFORM
The electrical waveform output of this inverter is a pure sine wave, which has the
same quality as utility and/or domestic power. This type of waveform is suitable for
most electrical devices, appliances and tools. This pure sine wave unit provides
more capabilities than modified sine wave inverters because it is a cleaner form of
power. The pure sine wave also effectively reduces the noise produced while using
appliances.
PROTECTIONS IN THE INVERTER
1. Input under-voltage alarm: When the input DC voltage is lower than 9.8V
(19.6V/39.2V), the buzzer will whistle intermittently to remind that the inverter
will go into under voltage protection.
2. Under voltage protection: The inverter will automatically shut down when the
input DC voltage is lower than 9.5V(19V/38V). The buzzer will whistle
continuously, the green light is off, red light is on. Please turn off the inverter
and use it after recharging the battery.
3. Over voltage protection: The inverter will automatically shut down when the
input DC voltage is higher than 16V(32V/62V). The buzzer will whistle
continuously, the green light is off, red light is on. Please turn off the inverter
and adjust the input voltage to the admissible range.
4. Overload protection: The inverter will automatically shut down when the load is
higher than the rated power. The buzzer will whistle continuously. Turn off the
inverter and resume to normal operation after taking away the excessive load.
5. Short-circuit protection: The AC output will automatically shut down when short
circuited. It will automatically reset after the problem is solved.
6. Thermal protection: The unit will get hot during operation. If the temperature is
higher than 149°F, the inverter will automatically shut down. Then the buzzer
will whistle continuously, the green light is off, red light is on. Please turn off
the inverter and continue using it after the temperature goes back to normal.
Meanwhile find out the factors causing the fault, such as ventilation, ambient
temperature, vent, load power etc. It can avoid similar things from happening
again.

**NOTE** The numbers in the parenthesis are for 24V and 48V models. In the case of
over voltage, under voltage and thermal protection, the inverter will shut down. When
the inverter is in the OFF position, the inverter doesn't consume battery current.
HI-POT TESTING OF DC to AC Inverter
Most of our AC inverters are Listed by Intertek to conform to UL 458 standards. One of
the requirements of UL 458 is that all AC inverters pass a High Voltage Dielectric
Withstand Test, commonly called the Hi-Pot Test. The voltage applied to the control is
usually equal to 1,000 volts, plus two times the line voltage rating of the inverter.
Therefore, the standard hi-pot voltage for 115 VAC inverter is 1,250 VAC. For 230 VAC
or dual voltage inverters, the hi-pot voltage is 1,500 VAC. This AIMS Power inverter is
hi-pot tested before it leaves the factory, with a UL Certified hi-pot tester, set to the
voltages shown above.
(CAN/CSA-C22.2 No. 107.1) and are identified with the cETL Listed Mark.

Low input DC voltage
Recharge or replace the battery
Do not use it when the battery is charging.
Check the rated voltage of the battery and
make sure it is in within the range of the input
voltage.
High input DC voltage
Overload
Reduce the load.
Over temperature
Cut off the load and let cool for 10 to 30
minutes. Restart it after it returns to normal
temperature. The load is too large, reduce
the total load to the range of rated power.
Avoid blocking the vent and improve the
ventilation condition. Reduce the ambient
temperature.
No output voltage
The switch is off
Turn on the power switch.
Poor cable connection
Check the cables and make sure they are tightly
connected and in good condition.
Incorrect output voltage
RMS Multimeter measurement error
Use a true RMS multimeter to measure,such
as model FLUKE 177/179.
The battery power of RMS
Multimeter is low.
Try to maintain the input voltage in the range
of rated power. The input voltage may be too
high or too low.
Change the battery of the multimeter then test
again.
Cannot power the load
Load is too large,or the actual
power of the appliance
exceeds nominal power.
Reduce the load,then turn on the
appliance first,then turn on the inverter.
The starting power is larger than
rated power (such as motor).
The internal inverter soft-start circuit will buffer
starting the appliance.
