Owner’s Manual

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 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!

a) Dry: Do not allow water to drip or splash on the inverter.

b) Cool: Ambient air temperature should be between 32 – 104 °F (0 – 40 °C).

c) Ventilated: Allow at least 2” (5 cm) 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) The inverter should be located within 10 ft (3 m) of the batteries.

4.2 Connecting and Testing

The following section describes how to connect and test the GP-3000HD inverters.

A reverse polarity connection will permanently damage the inverter.
Damage caused by reverse polarity connection is not covered by the
warranty.

This inverter must only be connected to batteries with a nominal output
voltage of 12 V. Lower voltages will not operate the inverter properly,
and higher voltages could damage the inverter or the device being
powered. If more than one 12 V battery is used, the batteries must be
connected in a parallel circuit; batteries connected in a series circuit will
produce too much voltage.

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.

1. Unpack and inspect your Go Power! inverter. Ensure that the power switch is in the
OFF position.

2. Install the inverters on a flat surface, ensure that it has adequate ventilation and is not
in direct sunlight. Securely fasten the inverter to the surface. We recommend using

GP-DC Install Kits whenever installing a GP Inverter.; see section 4.3 DC Install Kits.

www.gpelectric.com 8

Go Power! Modified Sine Wave Inverter

3. 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. Tighten
the terminal bolt or nut to clamp the wires securely. Ensure connections are tight.

4. Connect the ground cable to the appropriate location; see section 4.6 Grounding.

5. 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. Ensure connections are tight.

6. 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).

7. Install the inverter fuse into the positive lead. Fuse should be located within 12”
(31 cm) of battery. Ensure all connections are tight and secure.

8. Connect the cable from the positive terminal of inverter to the positive terminal of the
battery. Make a secure connection. Check your polarity.

Owner’s Manual

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.

9. Set the power switch to the ON position. Check the meters and indicators on the front
panel of the inverter. The voltage bar graph should indicate 11 to 14 V depending on
the voltage of the power source. If it is does not, check your battery bank and the
connections to the inverter. The other indicators should be OFF.

10. 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.

11. 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 DC Install Kits

4.4 Cables

DC to AC inverters require high amperage to operate properly; connect inverter DC input
terminals to battery with heaviest wire available; see Table 4-1.

Table 4-1: Wire Gauge

Max. Watts Out Approx. Amps Required (12 V DC) Wire Gauge*

3000 W >300 4/0

*It is recommended that the cable length not exceed 10 ft (3 m).

4.5 Inverter Fuse

A class “T” inverter fuse should be included in all installations.

GP-3000HD – 400 A fuse

4.6 Grounding

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 a 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 a grounding point.

The power inverter grounding point 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.

As per the national electrical code, electrical panels in mobile applications (boats, RVs
etc.) must not have a neutral to ground bond.

Owner’s Manual

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, one after another. This will
ensure that the power inverter does not have to deliver the starting currents for all the
loads at once.

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 – 2 A (see product specifications for exact current draw).

5.2 Optional On / Off Remote

The optional remote switch (sold separately) can be used to turn the inverter on and off
from a location up to 25 ft (8 m) away. The inverter should be OFF when plugging remote
in. Once the remote is installed the inverter ON/OFF switch must be in the ON position.

5.3 Battery Voltage Indicator

The battery voltage bar graph indicates the voltage at the input terminals of the power
inverter. At low input current, the display voltage will be very close to the battery voltage.
At high input current, the display voltage will be lower than the battery voltage.

Ideally, the voltage should remain in the green areas of the bar graph. If the voltage goes
into the red area at the top or bottom of the graph, the inverter may shut-down.

5.4 Battery Current Indicator

The battery current bar graph indicates the current drawn from the battery by the power
inverter. It will not indicate current by other loads also connected to the battery.

For long-term operation, the current should be in the green area of the bar graph. Short­term operation is possible with current in the yellow area. If the current rises to the red
area, the inverter will shut itself down and the overload indicator will light.

5.5 Power Output

The inverter will operate most AC loads within its power rating. When determining
whether a microwave oven can be operated by the Power Inverter, remember that the
power commonly advertised for microwave ovens is the cooking power (the power
delivered to the food), not the power actually consumed by the microwave oven. The
microwave oven will consume 40% to 100% more than its advertised cooking power.
Check the rating sticker on the back of the oven to determine its actual power draw.

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 V 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

www.gpelectric.com 12

Go Power! Modified Sine Wave Inverter

and the battery is charged, but the voltage still drops below 11 V, you may need to use a
larger battery.

Owner’s Manual

5.6 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 voltage indicator
will be in the lower red zone. 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. The voltage indicator will be in the upper red
zone. Although the power inverter incorporates protection against overvoltage, it may still
be damaged if the input voltage is allowed to exceed 20 V.

5.7 Hard Wire

The GP-3000HD AC output may be hard wired to the inverter. Remove the hard wire
cover and carefully pull out the three wires.

Do Not remove the hardwiring from the inverter while battery power is
supplied to the inverter.

Remove the ½ knockout on the hard wire cover. Pull the three wires through the knockout
opening and reattach the hard wire cover. Install a ½” cord grip or strain relief to protect
the wires.

The ground wire output is yellow and green, connect this first. The remaining two wires
are split phase at 60 volts each. This means they are both “HOT” and there is no neutral.
This is standard with most mod-sine wave inverters. Inverter operation will be fine for
mobile applications as long as the National Electrical Code is followed by ensuring the
neutral line is not bonded to ground anywhere in the system. See Grounding, Section

4.6.

The National Electrical Code recommends no less than #10 AWG for the hard wire
application. Use appropriately sized wire nuts. Seek professional assistance if you are
unfamiliar with electrical wiring.

6.0 T roubleshooting

6.1 Common Problems

Buzz in audio systems

Some inexpensive stereo systems will emit a buzzing noise from their loudspeakers when
operated from the power inverter. This is due to 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.

There are audible low voltage / over load alarms on all GP inverters.

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.

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.
