 Do not expose the Inverter to rain, snow, spray, bilge or dust.
 To reduce risk of hazard, do not cover or obstruct the
ventilation openings.
 Do not install the inverter in zero-clearance compartment.
Over hearting may result.
 To avoid a risk of fire and electronic shock, make sure that
existing wiring is in good electrical condition and that wire is
not undersized.
 Do not operate the Inverter with damaged or substandard
wiring.
2. Explosive Gas Precautions:
This equipment contains components that can produce arcs or
sparks to present fire or explosion. Do not install in compartments
containing batteries or flammable materials, or in locations that
require ignition-protected equipment. This includes any space
containing gasoline-powered machinery, fuel tanks, or joints,
fittings, or other connections between components of the fuel
system.
3. Precautions When Working With Batteries
If battery acid contacts skin or clothing, wash immediately with
soap and water. If acid gets into eyes, immediately flood eyes with
running cold water for at least 20 minutes and get medical attention
immediately.
 Never smoke or allow a spark or flame in vicinity of batteries
or engine. Do not drop a metal tool on the battery. The
resulting spark or short-circuit of the battery may cause an
explosion.
 Remove personal metal items such as rings, bracelets,
necklaces, and watches when working with a lead-acid battery.
A lead-acid battery produces a short-circuit current high
enough to weld a ring or similar metal, causing severe burn.

I. Pre-installation Information:
Before installing your inverter, please make sure that you have
appropriately-sized batteries. A battery that is too small will not
allow the inverter to perform to its full specification.
J. Electrical Requirements:
DC input voltage of the inverter must be the same as the battery
bank voltage.
DC cabling must be connected to the correct polarity terminal of
the battery bank (Red=Positive, Black=Negative).
DO NOT extend the DC cable length to the inverter unless you
are prepared to increase the diameter of the cable. If this is
necessary consult your supplier/installer for advice.
DO NOT connect AC power to the output of the inverter: THIS
WILL DAMAGE THE INVERTER.
Between the inverter and any generator / mains supply, install a
double pole “break-before-make” changeover switch, switching
both line and neutral.
K. Installation Requirements:
1. Where to install: The power inverter should be installed in a
location that meets the following requirements
 Dry – Do not allow water to drip or splash on the inverter, free of
salt or moisture-laden air.
 Temperature – Ambient air temperature should be between 0℃
40℃.
 Safety – Do not install in a battery compartment or other areas
where flammable fumes may exist, such as fuel storage or
engine compartments.
 Ventilation – Allow at least one inch of clearance around the
inverter for airflow. Ensure the ventilation openings on the rear
and bottom of the unit are not obstructed. The installation site
should not be susceptible to temperatures in excess of 50℃.
 Dust-free – Do not install the inverter in an environment where
either dust, wood particles or other filings/ shavings are present.
These can pull into the unit blocking the cooling fan.
 Close to battery/batteries – Avoid excessive cable lengths
(Mount the inverter between one and two meters from the
batteries) but do not install the inverter over or in the same
compartment as batteries. Use the recommended wire lengths

7
and sizes. Do not mount the inverter where it will be exposed to
the gases produced by the battery. These gases are very
corrosive and prolonged exposure will damage the inverter.
 Wall-mount – Inspection and operation are more convenient if
the unit is mounted at head height and the DC cables hang
naturally out of the way.
PLEASE READ THESE INSTRUCTIONS CAREFULLY BEFORE
COMMENCING INSTALLATION.
Installation should be performed by competent professional
electrical/renewable energy installer, as dangerous voltage can be
present. Complete the following steps in order shown:
1. Mounting
 Unpack your inverter from its shipping container and inspect the
unit for any obvious transit damage. Report any concerns
immediately to your supplier.
 Mount the inverter to a suitable surface, paying close attention to
the mounting requirements previously mentioned in this manual.
2. AC Wiring
Important: to satisfy warranty requirements and conditions, a
qualified electrician must perform all AC wiring.
3. DC Wiring
IT IS ESSENTIAL that the battery bank voltage matched the
DC input voltage rating of the inverter. Damage to the inverter
could result from improper voltage connections.
A Battery fuse must be installed between the batteries and
the inverter; appropriately sized Motor-starting fuses or similar
are recommended. Before making any connections, ensure
that the inverter ON/OFF Switch is in the OFF position.
Connect the inverter DC input cables to the battery terminal,
the BLACK cable to the negative battery terminal and the
RED cable to the positive battery terminal.

4. Ground Fault Circuit Interrupters (GFCI’s):
Installations in Recreational Vehicles (for North American
approval) will require GFCI protection of all branch circuits
connected to the AC output of the inverter. In addition, electrical
codes require GFCI protection of certain receptacles in
residential installations. While the output of the inverter is
equivalent to the waveform provided by utilities, compliance with
UL standards requires us to test and recommend specific GFCI’s.
State power has tested the following GFCI-protected 15A
receptacles and found that they functioned properly when
connected to the output of the inverter.
5. Making DC Wiring Connections:
Follow this procedure to connect the battery cables to the DC
input terminals on the inverter. Your cables should be as short as
possible (ideally, less than 10 feet / 3 meters) and large enough
to handle the required current, in accordance with the electrical
codes or regulations applicable to your installation. Cables that
are not an adequate gauge (too narrow) or are too long will
cause decreased inverter performance such as poor surge
capability, frequent low input voltage warning and shutdowns.
L . Connection and Testing
For a quick connection and performance check, please follow
these guidelines.
1. Unpack and inspect the power inverter, check to see that the power
switch in the OFF position.
2. Connect the DC NEGATIVE cable (BLACK) to the Negative (NEG-)
terminal on the battery. Next, connect the BLACK cable to the
negative terminal on the inverter.
The connection to the negative terminal of the inverter should be the
last connection made. A spark when making this final connection is
normal.

3. Before proceeding further, carefully check that cable you have just
connected from the negative terminal of inverter to the Negative
terminal of battery.
4. Connect the RED cable from the positive terminal of inverter to the
positive terminal of the battery. Make secure connection.
5. Set the power switch to the ON position, the indicator lights may
blink and the internal alarm may sound momentarily. This is normal.
6. Check the indicators on the front panel of the inverter. The voltage
bar graph indicate depending on the voltage of the battery. If it does
not, check your battery and the connections to the inverter. The
other indicators should be off. Plug the test load into the AC
receptacle on the front panel of the inverter.
Leave the test load switch off.
7. Set 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 true output r.m.s. Voltage of inverter, the meter such as
FLUKE 45 BACKMAN 4410 or TRIPLETT 4200 or other digital
meters must be used.

M. 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 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.
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.
The inverter operates from an input voltage ranging from:
10 to 16 VDC for 12V models
20 to 32 VDC for 24V models
42 to 62 VDC for 48V models
Peak performance for the inverter occurs when DC input between
10 to 16 volts for 12V models and 20 volts to 32 volts for 24V
Models, and 42 volts to 62 volts for 48V models, from 600 Watts up
to 3000 Watts.
2. Over voltage indicator:
The over voltage indicator indicates that the power inverter has
shut itself down because its input voltage higher than the detect
voltage (12V / 24V /48VDC versions.)
3. Under voltage indicator:
The under voltage indicator indicates that the power inverter has
shut itself down because its input voltage has been lower than
detect voltage (12V / 24V / 48VDC versions.)
4. Over temp indicator:
The over temp indicator indicates that the power inverter has shut
down because it 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.
5. Overload indicator:
The overload indicator indicates that 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.

11
N. Power Saving Adjustment:
Your inverterk inverter features automatic load-sensing, which
allows the inverter to wait in Standby mode until an AC load is
switched ON. When an AC load appears, the inverter will
immediately start. This feature conserves valuable battery energy
as the inverter uses only about 10% of normal power when in
standby mode (standby is indicated by flashing green lamp). The
amount of AC power is required to start the inverter can be
adjusted, following the procedure below. Ensure battery voltage is
at nominal, i.e. 12V or 24V as appropriate for your inverter.
Adjust load sensitivity for power saving mode as follows:
 Turn OFF all AC loads, keeping the AC wiring connected.
Some loads such as TVs must be turned OFF at the power
posing as they can still represent a small load to the inverter.
 Using a small screwdriver adjust the black plastic trim pot
located to the right of the two lamps below the power point.
Turning this control fully clockwise will override the standby
circuit and keep the inverter ON all the time: this could be
used if you have a very small load that must stay ON at all
times.
 Adjust the pot until the lamp is steady green, then turn the pot
back a little until the lamp flashes green. Allow 10 seconds
between adjustments for stabilization: clockwise is less
sensitive; counter-clockwise is increased sensitivity.
 NOTE: the trim pot is extremely sensitive.
 When the lamp flashes GREEN, the unit is in standby mode.
 Turn on the smallest AC load attached to the inverter. The
inverter should now deliver rated output voltage 120 or
240VAC, and AC status lamp should be GREEN, However, if
the lamp is ORANGE the sensitivity must be increased by
turning the control pot a little count-clockwise.
 Now turn OFF the AC load. The lamp should return to flashing
GREEN, indicating that the inverter is on standby. If this does
not occur, reduce sensitivity by turning the control pot a little
clockwise and check again.

12
O. Trouble Shooting:
AC output does not stay ON. Some AC loads may not be large
enough to hold the inverter ON. This condition is indicated by the
inverter turning off after every eight to ten seconds, then back on
again. The AC Status lamp will also be flashing orange.
There are two possible solutions:
Increase the sensitivity of the inverter by turning the Standby
control slightly counter-clockwise until the lamp shows steady
green; increase the amount of AC load on the inverter.
Inverter shuts down due to Over Temperature. Your inverter
will safely provide the output power defined in the technical data
section under the conditions specified. If the inverter shuts down
and indicates over temperature, it may be that you have exceeded
one of the parameters.
Check the following:
Ensure the inverter has adequate ventilation. Insufficient
ventilation can severely restrict the power output of your inverter.
Ensure that the true power rating of your appliance (including
power factor) is less than the output rating of your inverter.
Inverter shuts down when trying to start a load. A sudden surge in
load, such as a motor starting, may cause the inverter to shut
down. If this occurs; ensure the battery voltage is within
specifications when the device is trying to start: if the voltage falls
too far, you may need to increase the size of your batteries.
If the battery voltage is ok then the inverter power output may be
too small.
Common Problems:
1. 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.

13
 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 tem together with about 2 to 3
twists per foot. This minimizes radiated interference from the
cables.
