6.2 Overload

The status LED will be orange and will come on when 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.

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 inverter.

If the motor refuses to start, observe the battery voltage indicator while trying to start the
motor. If the battery voltage indicator drops below 11 volts while the inverter is attempting to
start the motor, this may be why the motor will not start. Make sure that the battery connec­tions are good and that the battery is fully charged. If the connections are good and the
battery is charged, but the voltage still drops below 11 volts, you may need to use a larger
battery.

6.3 Input voltage

The power inverter will operate from input voltage ranging 10 V – 15 V. If the voltage drops
below 10.7 V, an audible low battery warning will sound and the status LED will be orange.
The power inverter will shut down if the input voltage drops below 10 V. This protects your
battery from being over discharged.

The power inverter will also shut down if the input voltage exceeds 15 V. This protects the
inverter against excessive input voltage. Although the power inverter incorporates protection
against overvoltage, it may still be damaged if the input voltage is allowed to exceed 20 V.

7. Troubleshooting

7.1 Common problems

a) Buzz in audio systems

Some inexpensive stereo systems will emit a buzzing noise from their loud speakers
when operated from the power inverter. This is because the power supply in the device
does not adequately filter the modified sine wave produced by the power inverter. The only
solution is to use a sound system that incorporates a higher quality power supply.

b) 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 television.

4.6 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 AC distribution wiring will damage the unit and void the warranty.

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.

may damage inverter permanently.

Note: Minimum inverter DC cable & DC inverter fuse sizes, see section 4.3 and 4.4.

5.1 Controls and indicators

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 idle current is
approximately 1 A (see product specifications for exact current draw).

6. Operating limits

6.1 Overtemp

The status LED will be orange and will come on when the inverter has shut itself down
because the inverter 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.

4. Installation

4.1Where to install

The power inverter should be installed in a location that meets the following requirements:
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.

4.1 Hook-up and testing

T o hook-up the inverter please follow these guidelines:

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!

1. Unpack and inspect your Go Power! Inverter, check to see that the power switch is
in the OFF position. We recommend using DC Install Kits whenever installing a GP
Inverter.

2. When attaching the DC inverter cables to the power input terminals on the rear panel of
the power inverter. The (+) terminal is positive and (-) terminal is negative. Connect
the cables into the terminals by placing the lug connector between the washers and
tighten the terminal screw or nut to clamp the wires securely. Ensure connections are
tight.

Caution! A reverse polarity connection may permanently damage the

inverter. Damage caused by reverse polarity connection is not covered by our
warranty.

3. First 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. Ensure connections are tight.

4. Before proceeding further, carefully check that the cable you have just connected is
going from the negative terminal of inverter to the negative output terminal of the
power source (battery).

5. Install the inverter fuse into 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. It is normal to observe a spark during the final connection to the battery. Make
a secure connection. Check your polarity.

Caution! This inverter cannot supply power to any AC distribution wiring or

AC loads in which the neutral and ground are connected (bonded). Doing so will
destroy the unit and void the warranty. If you do not understand neutral to
ground bonding then please have a professional install your system for you.
See “Grounding” for more information.

7. Set the power switch to the ON position. Check that the power LED is ON, and if
not, check your battery bank and the connections to the inverter.

Warning! You may observe a spark when you make the final battery connec-

tion 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.

8. Set the power inverter switch to the OFF position. The power LED light may blink
and go dim. The internal alarm may sound momentarily . This is normal. Plug the test
load into the AC receptacle on the front panel of the inverter.

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 r.m.s. meter must be used for accurate readings.

10. Ensure battery interconnect cables are a minimum of #4 gauge wire and a maximum of
10” in length.
