4.1 INSTALLATION PRECAUTIONS
1.
Do not install the Inverter into a building’s electrical system. The Inverter is a vehicular
accessory. It is not designed to be safely used in a building’s electrical system and
has not been evaluated to meet building wiring codes. Improper application may
create a re or electric shock hazard.
2.
To allow proper cooling, install in an indoor well-ventilated area and do not cover ventilation
openings or cooling fans. Do not install in engine compartment. Avoid placing the
Inverter on carpets and rugs; they are not only ammable, but they also obstruct
vents underneath the Inverter.
3.
Keep combustible materials and gases away from the Inverter. The Inverter produces
sparks and heat during operation and could start a re.
4.
Connect to a 12 VDC power supply only. A power supply with lower voltage will not operate
the Inverter correctly, and higher voltage could damage the Inverter.
5.
Connect input polarity properly. Incorrect connection will damage the Inverter and void
warranty.
6. Keep the Inverter dry and clean. Do not expose to rain, snow, spray, bilge water, or dust.
7.
Use cables that are the appropriate size. The more power (amps) or the longer the cables,
the thicker they need to be to prevent overheating and re. See section 4.7 DC WIRING
SIZE.
8.
Install the Inverter as close to the DC source as possible, but not in a closed area with
vented lead-acid batteries. Vented lead-acid batteries release explosive hydrogen gas
that can be ignited by the Inverter.
9. Mount the Inverter horizontally.
10.
Verify that the installation surface has no hidden utility lines before drilling or driving screws.
11. This product is not a toy. Keep it out of reach of children.
12.
Do not use with positive ground electrical systems (most automobiles, trucks, and RVs
have negative ground systems).
13.
The positive (+) battery on the Inverter must be the last connection made, and must be
connected before the Inverter is turned on. There may be a small spark during the nal
connection. This is normal.
14. Properly ground the Inverter’s case as explained in this manual.
4. INSTALLATION

INSTALLATION
4.2 INVERTER SHUTDOWN
The Inverter has a number of shutdown points, for the safety of the operator, the Inverter,
and the devices being used with it.
•
If the DC input voltage drops too low, the alarm on the Inverter will sound. If the
input voltage drops further, the Inverter will shut down automatically to prevent
permanent battery damage. Recharge the battery as soon as possible.
•
If the DC input voltage exceeds 16 VDC, the Inverter will shut down automatically.
• If the output load power rises higher than the rating power of the Inverter, the
Inverter may shut down automatically.
•
The Inverter may automatically shut down if its internal temperature gets too high.
Note: even though this Inverter has built-in mechanisms to minimize damage, these situations
should be avoided because they can still damage the Inverter or battery.
4.3 WHERE TO INSTALL
Your Inverter should be installed in a location that meets the following requirements:
1. Dry: do not allow water to drip or splash on the Inverter.
2. Cool: ambient air temperature should be between 0°C and 40°C (the cooler the better).
3. Ventilated: allow at least two inches of clearance around the inverter for airow. Ensure
the ventilation openings on the rear and bottom of the unit are not obstructed.
4.
Safe: do not install the Inverter in the same compartment as batteries or in any compartment
capable of igniting ammable liquids such as gasoline.
5. The Inverter should be located within 10 feet of the batteries.
Page 17
gpelectric.com | [page 17]
4.5 INSTALLATION AND TESTING
Battery Type Selection:
• Use only deep-cycle lead-acid batteries with this Inverter, such as 12 volt marine/RV deep-cycle batteries. Do not use automotive, engine starting (SLI),
or maintenance-free wet cell batteries with this Inverter; they are designed for
repeated, shallow discharge and will wear out quickly.
•
Gel and AGM (Absorbed Glass Mat) batteries can be used with this Inverter, but
they require special charging procedures. Refer to battery supplier’s instructions.
1. Unpack and inspect the Inverter, and make sure the power switch is in the OFF position.
Note: we recommend using Go Power! DC Install Kits when installing a Go Power! Inverter
(sold separately). Check section 4.7 DC WIRING SIZE to determine what Install Kits works
for your Inverter.
2. Connect the DC Inverter cables into the power input terminals on the back of the Inverter.
Remember, the (+) terminal is positive and the (-) terminal is negative. Place the lug
connector between the washers and tighten the terminal screw or nut to clamp the wires
securely. Ensure connections are tight.
3. Connect the ground cable to the appropriate location; see section 4.8 GROUNDING.
INSTALLATION
4.
First, connect the DC Inverter cables from the negative terminal of the Inverter to the
negative terminal of the battery. Make sure the connection is secure.
5. Before proceeding further, carefully check that the cable you just connected is going from
the negative terminal of the Inverter to the negative output terminal of the battery.
6. Install the Inverter fuse into the positive lead. The fuse should be located within 12” (31
cm) of the battery. Ensure all connections are tight and secure.
7.
Connect the cable of the positive terminal of the Inverter to the positive terminal of the
battery. Make a secure connection. Check your polarity.
CAUTION! Equipment Damage.
Loose connections result in excessive voltage drop and may cause
overheated wires and melted insulation. Ensure connections are tight.
Page 18
[page 18] | gpelectric.com
INSTALLATION
CAUTION! Equipment Damage.
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, please have a professional install your system
for you. See section 4.8 GROUNDING for more information.
WARNING! Fire/explosion Hazard.
You may observe a spark when you make the nal battery connection
since current may ow to charge capacitors in the Inverter. Do not make
this connection in the presence of ammable fumes, as explosion or
re may result.
8.
Set the power switch to the ON position. Check the meters and indicators on the front
panel of the Inverter. The Function LEDs should be green showing the Inverter is ON.
If it does not, check your battery bank and the connections to the Inverter. The other
indicators should be OFF.
9. Set the 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.
10.
Set the 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.
Page 19
gpelectric.com | [page 19]
4.6 BATTERY PRECAUTIONS
1.
Wear splash-resistant ANSI-approved safety goggles and electrically-insulated gloves
while working near batteries.
2. Charge, store, and maintain batteries according to supplier’s instructions.
3.
Locate batteries in a clean, well-ventilated area, away from ignition sources and ammable
materials. Vented lead-acid batteries release explosive hydrogen gas while charging.
4.
Only connect similar batteries together. Do not connect old and new batteries together,
ooded and gel cells together, or batteries of different capacities together.
5.
Only connect this Inverter to a 12V nominal battery bank. Do not attempt to connect
the Inverter to any other power source other than a battery with a nominal output
voltage of 12 volts or damage to the Inverter may occur and will void the warranty.
6.
Connect batteries in parallel ONLY (negative terminals together to one cable; positive
terminals together to the other cable).
7. Install a properly rated fuse on the positive output of the battery bank. See section
4.7 DC WIRING SIZE.
The following points must be observed for the DC Wiring.
• The DC positive and negative cables connected to the Inverter from the battery
bank should be linked together with zip ties or electrical tape every 6”. This helps
to reduce radio frequency interference and reduces the effects of inductance both
of which improve the Inverter waveform and reduces the wear of the Inverters
lter capacitors.
•
To ensure optimum Inverter performance the number of connections between
the battery bank and the Inverter unit should be minimized except from the
over-current and battery disconnect devices. All additional connection points
will cause extra voltage drops.
• The Battery bank voltage must match the DC voltage required by the Inverter,
which is 12V.
•
All DC cable wire terminations should use a crimped and sealed copper ring
terminal lugs.
• Make sure all cables have a smooth bend radius and no kinks are present.
•
Colour code all DC Cables coming to/from the battery bank. Use coloured
electrical tape or heat shrink tubing. Red for positive (+), Black for negative (-)
and Green for DC ground.

4.7 DC WIRING SIZING
The distance between the battery bank and the Inverter should be as short as possible to
achieve maximum efciency and to reduce re hazards. The gauge of the cable should be
sized appropriately to limit the voltage drop to less than 2% when carrying the maximum input
current to prevent frequent low-input voltage warnings and shutdown. Only use high quality
copper wire.
The cables should be as short as possible and the overall length of both cables added together
should be less than 10 ft (3 m) to comply with code requirements. Keeping your wire runs as
short as possible helps to prevent: low voltage shutdowns and nuisance tripping of the DC
breaker because of increased current draw. The table below shows the recommended DC
cable size, fuses/circuit breakers and DC grounding cable sizes for the Inverter (note: these
values are correct for cables in free air, not conduit).

INSTALLATION
4.8 DC GROUNDING
To protect against electrical shock hazards, the Inverter metal chassis must be connected to
the DC grounding system. The DC grounding system is sometimes referred to as the Earth
ground or another designated ground. For example on an RV, the metal frame of the RV is
designated as the negative DC ground / RV ground.
The DC ground wire connection on the Inverter is used to connect the exposed chassis of the
Inverter to the DC grounding system. Use copper wire that is either bare or provided with green
insulation. The size of this conductor should be coordinated with the size of the over-current
devices used.
DC grounding involves proper grounding of the negative of the battery, the DC panel and the
DC side of the Inverter. The DC panel is normally used to connect the batteries and distribute
DC power to the Inverter and to the other DC loads.
A common earth ground should be used to bond the Inverter, negative bus bar and the negative battery terminal. All connections must be tight against bare metal. Use star washers to
penetrate paint and corrosion.
Page 22
[page 22] | gpelectric.com
5.1 OPERATING PRECAUTIONS
1.
Multiple outlet power strips with switches and circuit breakers only interrupt power to the “hot”
receptacle terminals. The “neutral” terminals remain powered with respect to the “ground”
terminals. So the strip switch may be off, but part of the device may still be powered.
2. Inspect supply connections before use to ensure they are tight and that insulation is not
damaged.
3.
Do not use this Inverter to power sensitive devices such as medical devices or computers.
Do not use in ignition protected areas.
4.
Some rechargeable devices can damage the Inverter. Check the temperature of the device
several times when it is charging. If the device becomes extremely hot; turn the power,
remove the device, and do not use with the Inverter.
5.
Check for breakage of parts and any other condition that may affect the Inverter’s operation.
If damaged, have it repaired before use.
6. Do not attempt to power a device, or combination of devices, that will require more than
the rated output of this Inverter. This may damage the Inverter of the attached devices.
7.
Appliances such as microwave ovens will normally draw more than their rated current.
For example, a typical 800 watt microwave oven will drawn approximately 1,200 watts.
8. Do not attach a battery charger if the charger carries a warning that dangerous voltages
are present at the battery terminals.
9.
Some uorescent lamps may not operate properly with this type of Inverter. If the bulb
appears to be too bright, or fails to light, do not use the lamp with this Inverter.
10.
Some fans with synchronous motors may slightly increase in speed when powered by the
Inverter. This is not harmful to the fan or to the Inverter.
11. The Inverter will consume some power while on, even without loads attached. Turn the
Inverter off after use.
5. OPERATION

5.2 CONNECTING AC LOADS
1. Plug 120V device(s) into the receptacles. Make sure all devices are turned off, and that
they do not use more than the rated wattage during continuous operation, otherwise they
may overload the Inverter.
2. Set the power switch to the ON position.
3. Turn the device(s) on, one at a time. If the alarm sounds, turn off the device(s). Unplug
the device(s) from the Inverter. Check the wattage of the device(s), and if plugging in
multiple devices, discontinue use of one or more. If a single device sets the alarm off, it
is not appropriate for use with the Inverter.
4.
If the Inverter is powered by a vehicle’s starting battery, be careful not to discharge the
battery to the point that it will no longer start the engine. If needed, operate the engine
periodically to maintain the batteries charge. Do not operate a vehicle’s engine in an
enclosed space.
5.3 CONTROLS AND INDICATORS
The ON/OFF switch turns the control circuit in the Inverter ON and OFF. It does not disconnect
power from the Inverter.
When the switch is in the OFF position, the 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 1-1.2A
(see product specications for the exact current draw).
5.4 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.

OPERATION
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 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 Inverter may not be able to start some
of these motors, even though their rated current draw is within the 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 11V 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 battery is charged,
but the voltage still drops below 11V, you may need to use a larger battery.
The following table shows the typical power consumption of common devices. Actual device
wattage requirements will vary. Some devices listed may require a pure sine wave Inverter
instead or proper operation.

5.8 OVERLOAD
The fault LED will come on when 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.
Some induction motors used in refrigerators, freezers, pumps and other motor operated
equipment requires 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 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.
OPERATION
5.6 INPUT VOLTAGE
The Inverter will operate from input voltage ranging 10.5 - 16V. If the voltage drops below
10.5 V, an audible low battery warning will sound and the voltage indicator will be in the lower
red zone. The Inverter will shut down if the input voltage drops below 10 V. This protects your
battery from being over discharged.
The Inverter will also shut down if the input voltage exceeds 16V. 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 20V.
5.7 OVERTEMP
The fault LED will come on when the Inverter has shut itself down because the Inverter has
become overheated. The Inverter may overheat because it has been operated at power levels
above its rating, or because it has been installed in a location that does not allow it to dissipate
heat properly. The power inverter will restart automatically once it has cooled off.
