4. Installation
4.1 Where to install
The power inverter should be installed in a location that meets the following
requirements:
Caution
Do not connect this inverter and another AC source (generator or utility power) to the AC
wiring or AC loads at the same time. Doing so will destroy the inverter and void the
warranty, regardless whether the inverter is switched on or off. If you are using more than
one AC source for the AC wiring or AC loads, it is highly recommended that you install an
automatic transfer switch (GP-TS), available from Go-Power Electric Inc.
a) Dry - Do not allow water to drip or splash on the inverter.
b) Cool - Ambient air temperature should be between 0°C and 40°C (the cooler the
better).
c) Ventilated - Allow at least two inches of clearance around the inverter for air flow.
Ensure the ventilation openings on the rear and bottom of the unit are not
obstructed.
d) Safe - Do not install the inverter in the same compartment as batteries or in any
compartment capable of igniting flammable liquids such as gasoline.
e) Inverter should be located within 10 feet of the batteries.

4.2 Hook-up and testing
1. Unpack and inspect your Go Power! Inverter, check to see that the power switch
is in the OFF position.
2. Connect the negative cable (black) to the negative terminal of the battery. Make a
secure connection.
Caution! Loose connections result in excessive voltage drop and may cause
overheated wires and melted insulation.
3. Before proceeding further, carefully check that the cable you have just connected,
connects from the negative terminal of inverter to the negative output terminal of
the power source.
4. Install the recommended inverter fuse in positive lead. Fuse should be located
within 12” of battery. Ensure all connections are tight and secure. (See 4.3)
5. Connect the positive cable (red) to the positive terminal of the battery. Make a
secure connection.
6. Set the power switch to the ON position. Check indicator on the front panel of
the inverter to ensure that it is red.
7. Set the power inverter switch to the OFF position. The indicator light may blink
and the internal alarm may sound momentarily. This is normal. Plug the test load
into the AC receptacle on the front panel of the inverter.
8. Set the power inverter switch to the ON position and turn the test load on; the
inverter should supply power to the load. If you plan to measure the output voltage
of the inverter, a true r.m.s. meter must be used for accurate readings.
4.3 Cables
Please use a 40 amp fuse (not included) with the supplied #10 Cable. Install the inverter
fuse into the positive lead. Fuse should be located within 12” of battery. Ensure all
connections are tight and secure.
4.4 Grounding
The power inverter has a lug on the rear panel: “Chassis Ground.” This is to connect the
chassis of the power inverter to the ground. The ground terminals in the AC outlets on the
front of the inverter are also connected to the ground lug.
If available, the chassis ground lug should be connected to a ground point, which will vary
depending on where the power inverter is installed. In a vehicle, connect the chassis
ground to the chassis of the vehicle. In a boat, connect to the boat’s grounding systems.
In a fixed location, connect the chassis ground lug to earth.
The neutral (common) conductor of the power inverter AC output circuit is not bonded to
the chassis ground. Therefore, when the chassis is connected to ground, the neutral
conductor will not be grounded.
At no point should the chassis ground and the neutral conductor of the inverter be bonded.
Bonding the chassis ground and the neutral conductor of the inverter or connecting the
inverter to household or recreational AC distribution wiring will damage the unit and void
the warranty.
Warning!
Do not operate the
power inverter
without connecting it
to ground. Electrical
shock hazard may
result.
Caution!
A
reverse polarity
connection will blow a
fuse in the inverter and
may permanently
damage the inverter.
Damage caused by
reverse polarity
connection is not
covered by our
warranty.
Warning!
You may observe a
spark when you
make the positive
connection since
current may flow to
charge capacitors in
the power inverter.
Do not make this
connection in the
presence of
flammable fumes, as
explosion or fire may
result.

Caution!
The negative DC input of the power inverter is connected to the chassis. Do not install the
power inverter in a positive ground DC system. A positive ground DC system has the
positive terminal of the battery connected to the chassis of the vehicle or to the grounding
point.
5. Operation
To operate the power inverter, turn it on using the ON/OFF switch on the front panel. The
power inverter is now ready to deliver AC power to your loads. If you are operating
several loads from the power inverter, turn them on separately after the inverter has been
turned on. This will ensure that the power inverter does not have to deliver the
starting-currents for all the loads at once.
5.1 Operating On/Off Switch
The ON/OFF switch turns the control circuit in the power inverter ON and OFF. It does
not disconnect power from the power inverter.
When the switch is in the OFF position, the power inverter draws no current from the
battery. When the switch is in the ON position but with no load, the power inverter draws
approximately 0.20 A from the battery.
5.2 Power Status
The power status LED indicates the operating state of the inverter. If the LED is green,
then the inverter is in operational mode and producing approximately 115 V AC. If the
LED is red or flashing red, then the inverter is in fault mode and there is no AC output.
Some common faults include:
5.2.1 Over voltage indicator (Red LED Blinking Fast)
The over voltage indicator indicates that the power inverter has shut itself down because
its input voltage has been over 16.5 VDC for the 12 V and 32.0 VDC for the 24 V.
5.2.2 Under voltage indicator (Red LED Blinking Slowly)
The under voltage indicator indicates that the power inverter has shut itself down because
its input voltage has been lower than 10.0 VDC for the 12 V and 20.0 VDC for the 24 V.
5.2.3 Over temp indicator: (Red LED Blinking Intermittently)
The over temp indicator indicates that the power inverter has shut itself down because it
has become overheated. The power inverter may overheat because it has been operated
at power levels above its rating, or because it has been installed in a location which does
not allow it to dissipate heat properly. The power inverter will restart automatically once it
has cooled off.
5.2.4 Overload indicator: (Red LED Solid)
The overload indicator indicates that the power inverter has shut itself down because its
output circuit has been short circuited or drastically overloaded. Switch the ON/OFF switch
to OFF, correct the fault condition, and then switch the ON/OFF switch back to ON.
5.3 Resetting Faults
Any of the inverters protection faults can be re-set by turning the inverter off for five
seconds and then turning the inverter on again. The GP-SW150 can also re-set any of its
protection faults using the optional remote on/off switch to turn the inverter off and then on
again.

5.4 Remote
A user supplied remote option is available. When the on/off button is put to the remote
setting, the inverter will only work if a connection is made between the two terminals of the
remote input. A small screwdriver may be used to tighten the two terminals. A switch may
be placed between the two terminals and the inverter will now be turned off via the switch.
It is recommended that #18 gauge wire no more that 150 feet (terminal to terminal) be
used for this application.
6. Operating limits
6.1 Power output:
Some induction motors used in refrigerators, freezers, pumps, and other motor-operated
equipment require very high surge currents to start. The power inverter may not be able to
start some of these motors even though their rated current draw is within the power rating
of inverter. Televisions and computer monitors may surge up to four times their rated
power on startup, which may result in the inverter showing an overload fault.
6.2 Input voltage:
The power inverter will operate from input voltage ranging 10 V – 15 V (12 V) /
20 V – 30 V (24 V). The power inverter will shut down if the input voltage drops below
10 / 20 V. This protects your battery from being over discharged.
The power inverter will also shut down if the input voltage exceeds 16 / 32 V. This
protects the inverter against excessive input voltage. Although the power inverter
incorporates protection against over voltage, it may still be damaged if the input voltage is
allowed to exceed 20 / 40 V.
7. Troubleshooting
7.1 Common problems
Television interference: Operation of the power inverter can interfere with television
reception on some channels. If this situation occurs, the following steps may help to
alleviate the problem.
• Make sure that the chassis ground lug on the back of the power inverter is solidly
connected to the ground system of your vehicle, boat or home.
• Do not operate high power loads with the power inverter while watching television.
• Make sure that the antenna feeding your television provides an adequate ("snow
free") signal and that you are using good quality cable between the antenna and the
TV.
• Move the television as far away from the power inverter as possible.
• Keep the cables between the battery and the power inverter as short as possible
and twist them together with about 2 to 3 twists per foot. This minimizes radiated
interference from the cables.
