4. Installation
4.1 Where to install
The power inverter should be installed in a location that meets the following requirements:
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.
Dry – Do not allow water to drip or splash on the inverter.
Cool – Ambient air temperature should be between 32 and 104 °F (0 and 40 °C) (the
cooler the better).
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.
Safe – Do not install the inverter in the same compartment as batteries, or in any
compartment capable of igniting flammable liquids such as gasoline.
Inverter should be located within 10 feet (3 m) of the batteries.
4.2 Hook-up and testing
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 warranty.
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.
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).
You may observe a spark when you make this 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.

Go Power! GP-SW3000, GP-SW2000, GP-SW1000and GP-SW600
Owner’s Manual

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.
The GFCI outlet and the Hard Wire terminal of the GP-SW3000 are
rated for 20 amps or 2200 watts each. Do not exceed a combined load
of 20 amps or 2200 watts for either the GFCI outlet or the Hard Wire
terminal. Do Not jumper the GFCI outlet or the Hard Wire terminal
together.
4.3 Hard Wire (GP-SW3000 and GP-SW2000
Ensure the inverter is turned off if connecting the Hard Wire option.
The GP-SW3000 and 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” or with the standard
ground symbol and is located to the right of the terminal strip. The National 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
Install the inverter fuse into the positive lead. Fuse should be located
within 12” of battery. Ensure all connections are tight and secure.
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.

A GP-DC Kit 5 suitable for 12 V and a GP-DC Kit 3 suitable for 24 V applications is
available from Go Power Inc.
4.5 Grounding
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.
Do not operate the power inverter without connecting it to ground.
Electrical shock hazard may result.
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.
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 and GP-SW3000) from the battery. When in Power Save mode the
GP-SW1000, GP-SW2000 and GP-SW3000 will draw approximately 3.0 W from the
battery.
5.2 Input Level (battery voltage) indicator
The GP-SW600, GP-SW1000, GP-SW2000 and GP-SW3000 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). 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 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, GP-SW2000 and GP-SW3000)
The status LED indicator 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, 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, GP-
SW2000 and GP-SW3000) will come on and the AC output will disconnect.
5.7 Low / Under Voltage Indicator (UVP)
During low voltage, the 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, GP-SW2000 and GP-SW3000) 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, GP-SW2000
and GP-SW3000) 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 if the inverter disconnect the AC output. The fault
light (GP-SW600) or status light (GP-SW1000, GP-SW2000 and GP-SW3000) will appear
solid red and the Load Level LED will turn off.
5.10 Power Saving Indicator (GP-SW1000 and GP-SW2000)
These Inverters include 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. 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 7 W will not wake up the inverter
and the inverter will remain in power save mode.

5.11 What is Power Saving?
(GP-SW1000, GP-SW2000 and GP-SW3000)
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, GP-SW2000 and GP-SW3000 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.
