4.0 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
Table 2 & 3 in Section 5.6, Power Save.
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.

GP-HS1500
___________________________________________________________

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.
5. Install inverter fuse (not included) on the positive lead. Fuse should be
located within 12” of battery. Ensure all connections are tight and secure.
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.
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 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-HS1500-12V: Please use 10 ft or less of #2 Cable with a 200 Amp fuse.
GP-HS1500-24V: Please use 10 ft or less of #4 Cable with a 100 Amp fuse.
A DC install kit is available from Go Power! Use GP-DC-KIT3 for 12V models
and GP-DC-KIT2 for 24V models.

4.4 Grounding
The inverter has a chassis ground lug on the rear panel allowing you to connect the
chassis of the inverter to ground. The ground terminals in the AC outlets on the
front panel of the inverter are internally connected to the chassis ground. If
available, the chassis ground lug should be connected to a grounding point, which
will vary depending on where the inverter is installed. In a vehicle, connect the
chassis ground to the chassis of the vehicle. In a boat, connect the chassis ground
lug to the boat's grounding system. In a fixed location, connect the chassis ground
lug to an earth ground.
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 a ground, the neutral conductor is also grounded. These grounding
connections conform to national electrical code requirements which state that
separately derived AC sources (such as inverters and generators) have their
neutral conductors tied (bonded) to ground in the same way that the neutral
conductor from the utility line is tied (bonded) to ground in the AC breaker panel of
a non-mobile dwelling.
Important:
As per the national electrical code, electrical panels in mobile applications must not
have a bonded neutral. 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 on inverters with GFCI outlets, the GFCI outlet will trip and
output power from the inverter will be cut off. If your GFCI repeatedly needs to be
reset, this indicates a ground loop somewhere in your system. In this case, please
have a qualified service technician inspect your electrical system or equipment.
The negative DC input of the inverter is connected to the
chassis. Do not install the 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.
5.0 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

GP-HS1500
___________________________________________________________
10
the ON position but with no load, the power inverter draws less than 14.4 W from
the battery. When in Power Save mode the GP-HS1500 will draw approximately
1.45 W from the battery.
5.2 Input Level (battery voltage) indicator
The 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.
5.5 Status Indicator 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 Table 1 – Inverter power states.

Over temperature
protection Red LED blinking intermittently Over temperature protection indicates that the inverter has shut
itself down because it has become
overheated.
The inverter may overheat if it has
been operated at power levels above
its rating or if it has been installed in
a location which does not allow it to
properly dissipate heat. The inverter
automatically restarts once it has
cooled down.
Overload
protection
Red LED solid Overload protection indicates that
the 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.
5.6 Power Saving Mode
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.

5.7 What is Power Saving?
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
5.8 Remotes
The GP-HS1500 is available with an optional remote (GP-SWR-B or GP-SWR-A).
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.

6.0 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 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 inverter operates at the following input voltage ranges:
•12 V: 10.5 to 15.0 V
•24 V: 21.0 to 30.0 V
The inverter shuts down if the input voltage drops below:
•12 V: 10.5 V
•24 V: 21.0 V
This protects your battery from being over discharged.
The inverter also shuts down if the input voltage exceeds:
•12 V: 15.0 V
•24 V: 30.0 V
This protects the inverter against excessive input voltage. Although the inverter
incorporates protection against over voltage, it may still be damaged if the input
voltage is allowed to exceed:
•12 V: 20.0 V
•24 V: 35.0 V
7.0 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.

GP-HS1500
___________________________________________________________
14
•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.
