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 of the inverter’s on or off status. 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 airflow.
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
For hook-up, please follow these guidelines:
1. Unpack and inspect your Go Power! Inverter, then check to see that the power switch
is in the OFF position. Set up your power output according to Section 10, Configuring
your Sine Wave.
2. Insert DC inverter cables (not included) to the power input terminals on the rear panel
of the power inverter. The red terminal is positive (+) and black terminal is negative
(-). Connect the cables into the terminals and tighten the terminal screw to clamp the
wires securely.
3. Connect the cable from the negative terminal of the inverter 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.
4. Before proceeding further, carefully check that the cable you have just connected
connects from the negative terminal of inverter to the negative terminal of the power
source (battery).
5. Install inverter fuse (not included) in positive lead. Fuse should be located within 12” of
battery. Ensure all connections are tight and secure. (See Section 4.3)
6. Connect the cable from the positive terminal of inverter to the positive terminal of the
battery. Make a secure connection.
7. Set the power switch to the ON position. Check the indicators on the front panel of
the inverter. The Input Level LED should be green or yellow, depending on the
voltage of the power source. If it is not, check your battery bank and the connections
to the inverter.
8. Set the power inverter switch to the OFF position. The indicator lights 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. Leave the test load switch OFF.
(For the Hard Wire option, please see Section 4.3).
9. 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 rms meter must be used for accurate readings.
4.3 Hard Wire (GP-SW2000)
The GP-SW2000 AC output may be hard wired into the inverter. Remove the four screws
that surround the AC outlet and strain relief clamp to reveal a two-connection terminal
strip. Feed a user-supplied power cable through the strain relief clamp, tighten the clamp,
and make the connections.
The Black or HOT wire output is labeled “L” and the white or NEUTRAL wire output is
labeled “N”. The Green or GROUND wire connection is labeled “FG” and is located to the
right of the terminal strip. The Canadian Electrical Code recommends no less than #12
gauge wire for this application. Seek professional assistance if you are unfamiliar with
electrical wiring.
4.4 Cables
GP-SW600-12V: Please use 8 ft or less of #6 Cable with a 70 Amp fuse.
GP-SW600-24V: Please use 8 ft or less of #8 Cable with a 70 Amp fuse.

Install the inverter fuse into the positive lead. Fuse should be located within 12” of battery.
Ensure all connections are tight and secure.
4.5 Grounding
The power inverter has a lug on the rear panel [chassis ground]. This is to connect the
chassis of the power inverter to ground. The ground terminals in the AC outlets on the
front panel of the inverter are also connected to the ground lug.
The chassis ground lug must be connected to a grounding 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 inverter AC output circuit is connected (bonded) to
the chassis ground inside the inverter. Therefore, when the chassis is connected to
ground, the neutral conductor will also be grounded. This conforms to national electrical
code requirements that states that separately derived AC sources (such as inverters and
generators) have their neutral tied to ground in the same way that the neutral conductor
from the utility line is tied to ground at the AC breaker panel.
Important:
If the inverter is supplying power to equipment or a panel where the neutral and ground
are connected (bonded), a ground loop will occur. If a ground loop occurs, the GFCI outlet
will trip and output power from the inverter will be cut off. If your GFCI repeatedly needs to
be reset, this would indicate a ground loop somewhere in your system. In this case, please
have a qualified person inspect your electrical system or equipment.
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
less than 2.5 W (GP-SW600), 14.4 W (GP-SW1000, GP-SW2000) from the battery. When
in Power Save mode the GP-SW1000 and GP-SW2000 will draw approximately 3.0W
from the battery.
5.2 Input Level (battery voltage) indicator
The GP-SW600, GP-SW1000 and GP-SW2000 Input Level LED changes colour from
green to yellow to red as battery voltage decreases from a resting voltage of 12.7 V -
10.5 V (12 V) or 25.4 V – 21V (24 V).
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.
Warning!
Do not operate
the power inverter
without
connecting it to
ground. Electrical
shock hazard may
result.

Go Power! GP-SW2000, GP-SW1000 and GP-SW600
Inverter Owner’s Manual
13
The Input Level LED changes colour from green to yellow to red as battery voltage
increases from a resting voltage of 12.7V – 15.0 V (12 V) or 25.4 V – 30.0 V (24 V).
5.3 Load Level Indicator
The GP-SW600, GP-SW1000 and GP-SW2000 Load Level LED Indicator changes color
from green to yellow to red as the load is increased. The Load Level LED Indicator will be
red at peak wattage or peak load.
The Load Level LED Indicator should be green or yellow for long-term operation.
Short-term operation is possible with the load indicator in the red area. If the load rises to
dangerous levels, the inverter will protect itself and shut down.
5.4 Fault Indicator (GP-SW600)
Any of the inverter’s protection faults can be re-set by turning the inverter off for five
seconds, correcting the fault, and then turning the inverter on again (see Section 5.6 –
5.9).
5.5 Status Indicator (GP-SW1000 and GP-SW2000)
The status LED indicator on the GP-SW1000 will display the operating condition of the
inverter. A solid green LED is normal. A flashing green LED indicates the inverter is in
power save mode (see Power Saving). A red LED, flashing or otherwise, indicates a fault
(see Section 5.6 – 5.9).
5.6 Over Voltage Indicator (OVP)
During over voltage, the GP-SW600 and GP-SW1000 Input Level LED will continually
flash red four times per second, five double beeps will sound, the fault light (GP-SW600)
or status light (GP-SW1000 and GP-SW2000) will come on and the AC output will
disconnect.
5.7 Low / Under Voltage Indicator (UVP)
During low voltage, the GP-SW600 and GP-SW1000 Input Level LED will continually flash
red twice per second and five single beeps will sound every eight seconds. During under
voltage the Input Level LED will continually flash red twice per second, five double beeps
will sound, the fault light (GP-SW600) or status light (GP-SW1000 and GP-SW2000) will
flash red twice per second and the AC output will disconnect.
5.8 Over Temp Indicator (OTP)
During over temp, the fault light (GP-SW600) or status light (GP-SW1000 and GP-
SW2000) will continually flash red twice every other second, five double beeps will sound
and the AC output will disconnect.
5.9 Maximum Load / Overload Indicator (OLP)
During maximum load, the GP-SW600, GP-SW1000 and GP-SW2000 Load Level LED will
flash red twice per second and five single beeps will sound every eight seconds. During
overload, the Load Level LED will flash red twice per second, five double beeps will sound
and the AC output will disconnect. The fault light (GP-SW600) or status light (GP-SW2000
and GP-SW1000) will appear solid red and the Load Level LED will turn off.
5.10 Power Saving Indicator (GP-SW1000 and GP-SW2000)
The GP-SW1000 and GP-SW2000 Inverter includes a power saving mode. When power
saving is enabled and there is no load present, the inverter will draw approximately three
watts of power.
The LED will be solid green if a load is present, and flashing green once every second if
there is no load present. If the inverter has just been powered up and power saving is
enabled, the LED will remain solid green for approximately 10 seconds and then start to
flash if there is no load present.

Go Power! GP-SW2000, GP-SW1000 and GP-SW600
Inverter Owner’s Manual
14
Power saving is enabled and adjusted through dip switches S1, S2, and S3 on the front of
the inverter.
Example: With the watt setting at 7 W, a 7 W or greater load will “wake up” the inverter
and the load will operate normally. Any load less than 7W will not wake up the inverter and
the inverter will remain in power save mode.

> 50 W ON ON ON
To disable power saving, leave dip switches S1, S2 and S3 in the OFF or 0 position
5.11 What is Power Saving? (GP-SW1000 and GP-SW2000)
Power saving mode enables the inverter to be “on” and waiting for a load, yet draw very
little power. When power saving is enabled and the inverter senses a load, it may take one
second for the load to become active. This one-second wait will be fine for loads that
draw continually, such as televisions and stereos.
However, it may not be suitable for loads that are intermittent such as bread makers,
power tools or blenders. Power saving will continually draw a small amount of power from
the batteries, so if the inverter will not be in use for longer than a day, it is advisable to turn
the inverter off using the on/off switch located on the front of the inverter or remote.
5.12 Remote
The GP-SW1000 and GP-SW2000 are available with an optional remote. The remote will
turn the inverter on and off and indicate normal operation or any faults that have caused
the inverter to shut down. The remote will show battery voltage and power consumption.
The remote will show if the battery voltage is too high and will sound an alarm if the battery
voltage falls too low (Under Voltage). The remote will also sound an alarm if the output
power is above the inverter specifications (Overload). The Under Voltage and Overload
alarm consists of five single beeps every eight seconds.
6. Operating limits
6.1 Input voltage:
The power inverter will operate from input voltage ranging 10.5 V – 15 V (12V) or 21 V- 30
V (24V). If the voltage drops below 11 V (12 V) or 22 V (24 V), the Input Level LED will
flash red twice per second and five single beeps will sound every eight seconds. If the
voltage drops below 10.5 V (12 V) or 21 V (24 V), the Input Level LED will flash red twice
per second, five double beeps will sound, the fault light will come on and the AC output
will disconnect. This protects your battery from being over discharged.
The power inverter will also shut down if the input voltage exceeds 15 V (12 V) or 30 V (24
V). This protects the inverter against excessive input voltage. If the voltage rises above 15
V (12 V) or 30 V (24 V), the Input Level LED will flash red four times per second, five
double beeps will sound, the fault light will come on and the AC output will disconnect.
Although the power inverter incorporates protection against over voltage, it may still be
damaged if the input voltage is allowed to exceed 20 V (12 V) or 40 V (24 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 two to three twists per foot. This minimizes
radiated interference from the cables.
