1. Important Safety Instructions
WARNING!
Before using the Inverter, you need to read and save the
safety instructions.
When the photovoltaic array is exposed to light, it supplies
DC voltage to the PCE!
1-1. General Safety Precautions
1-1-1. Do not expose the Inverter to water, mist, snow, spray, or dust. To
reduce risk of hazard, do not cover or obstruct the ventilation shafts. Do
not install the Inverter in a zero-clearance compartment. Overheating may
occur.
1-1-2. To avoid a risk of fire and electronic shock, make sure that existing
wiring is in good electrical condition and not undersized. Do not operate
the Inverter with damaged or substandard Wiring.
1-1-3. There are some components in the inverter can cause arcs and
sparks. To prevent from fire or explosion, do not put batteries,flammable,
materials, or anything should be ignition–protected around the inverter.
1-2. Precautions When Working with Batteries
1-2-1. If battery acid contacts skin or clothing, you shall wash it out with
soap and water immediately. If battery acid contacts your eyes, you shall
wash it out with cold running water for at least 20 minutes and get medical
attention immediately.
1-2-2. Never smoke or make a spark or flame in the vicinity of the battery
or the engine.
1-2-3. Do not drop a metal tool on the battery. The resulting spark or short-
circuit on the battery of other electrical part may cause an explosion.
1-2-4. Remove personal metal items such as rings, bracelets, necklaces,
and watches when operating with a lead-acid batteries. Doing so may
cause short circuit and very high temperature, which can melt metal items
and even burn you.

6. Installation and Warning
6-2 Installation : The power inverter should be installed in an environment
that meets the following requirements Dry – Do not allow water to drip on or
enter into the inverter.
Cool – Ambient air temperature should be between 0and 40, the cooler the
better.
Safe – Do not install the inverter in a battery compartment or other areas
where flammable fumes may exist, such as fuel storage areas or engine
compartments.
Ventilated –Keep the inverter a distance (as least 1 inch) away from
surrounding things.Ensure the ventilation shafts on the rear and the bottom of
the unit are not obstructed.
Dust – Do not install the Inverter in a dusty environments. The dust can be
inhaled into the unit when the cooling fan is working.
Close to batteries – Avoid excessive cable lengths.
Do not install the Inverter in the same compartment as batteries.
Use the recommended wire lengths and sizes(8AWG). 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.
WARNING!
Shock Hazard. Before proceeding further, carefully check that
the Inverter is NOT connected to any batteries, and that all wiring
is disconnected from any electrical sources. Do not connect the
output terminals of the Inverter to an incoming AC source.
CAUTION!!
This equipment is not ignition protected and employs components that tend
to produce
Arcs or sparks. To reduce the risk of fire or explosions, do not install in
compartments Containing batteries or flammable materials or areas in which
ignition protected equipment is required.
CAUTION!!
To reduce the risk of electric shock and prevent premature failure due to
corrosion,
do not mount where exposed to rain or spray.
CAUTION!!
To prevent fire, do not obstruct ventilation openings. Do not mount in a zero
clearance
compartment,overheating may result.

CAUTION!!
Risk of electrical shock. DC voltage source is existed inside this
equipment.Each circuit must be individually installed.
CAUTION!!
Risk of electrical shock. Do not remove cover, no user serviceable parts
inside. Refer servicing to qualified service personnel.
APPLICATION INFORMATION:
Provided with integral electronic protection against AC & DC overloads.
6-2: please follow these guideline to install the inverters :
A . Unpack and inspect the inverter,check to see that the power switch in the
OFF position.
B. Connect the cables to the power input terminals of inverter.
The red terminal is positive (+) and black terminal is negative (-). Connect
the cables into the terminals and tighten the wing nut to the wires securely.
C. Connect the cable from the negative terminal of the inverter to the
negative terminal of the power source. Make a secure connection.
CAUTION!!
Loosely tightened connectors result in excessive drop and may
cause overheated wires and melted insulation.
D. Before proceed further, carefully check if the terminals connect correctly.
CAUTION!!
Reverse polarity connection will blow a fuse in inverter and may
permanently damage the inverter. Damage caused by reverse
polarity connection is not covered by our warranty.
E. Connect the cable from the positive terminal of inverter to the positive terminal of
the power source. Make secure connection.
WARNING!!
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,
explosions or fire may result.
F. Insert the MC4 connector of solar panel to the port .Make sure that the
polarity of PV array is right connected . G.Set power inverter switch to the
ON position and turn the test load on, the inverter should supply power to
the load.

6-3. Inverter Operation
To operate the power inverter, use the ON / OFF switch on the Front panel
to turn the power on. Then the power inverter is ready to deliver AC power
to your loads. If there is several loads use, turn them on separately after the
inverter is “ON” in order to prevent OVP resulted from the surge power.
6-3-1. Set the power switch to “ON” position .Then the inverter will make
self- diagnosis, and the LED’s indicators will turn to “Green” color, then the
inverter starts to work successfully.
6-3-2. Set the power switch to the OFF position, then the inverter stops and
all the lights go Off.
CAUTION!!
If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired!
6-4 .Battery Installation and Replacement :
6-4-1 : Recommend battery：One piece 12V 100AH-130AH Lead-acid or
Gel battery with free maintenance.
6-4-2. When replacing batteries, replace with the same type and number of
batteries or battery packs with recommend. General instructions regarding
removal and installation of batteries;
CAUTION!!
Do not dispose of batteries in a fire. The batteries may explode;
CAUTION!!
Do not open or damage batteries. Released electrolyte is harmful to the skin and
eyes. It may be toxic;
CAUTION!!
A battery can present a risk of electrical shock and high short-circuit current.
6-4-3:The following precautions should be observed when working on
batteries:
A. Remove watches, rings, or other metal objects.
B. Use tools with insulated handles.
C. Wear rubber gloves and boots.
D. Do not lay tools or metal parts on top of batteries.
E. Disconnect charging source prior to connecting or disconnecting battery
terminals.
F. Determine if battery is inadvertently grounded. If inadvertently grounded,
remove source from ground. Contact with any part of a grounded
battery can result in electrical shock. The likelihood of such shock can
be reduced if such grounds are removed during installation and
maintenance (applicable to equipment and remote battery supplies not
having a grounded supply circuit).
