1) Assemble the remote controller box
(1) Fix the remote box on flat surface (No need a hole ), and use 2 screws to fix it through
the two mounting holes on the remote controller.
(2) Also it is available to fix on a 86*86mm standard Electrical box.
(3) Connect the remote box and inverter with the wire.
Note:
In case not connect to the remote controller, the inverter can be also used as a
normal pure sine wave inverter, turned on by the power switch on the item.
E. BATTERY
1) Current and voltage
The battery is designed to supply the unit with DC input voltage and the rated voltage
should be in accordance with the rated input voltage of the inverter. Any voltage exceeds
the range of the input voltage of the inverter will cause over voltage or under voltage
protection.
In the meantime, the battery should supply sufficient current. The small capacity battery
cannot drive the large power electrical appliance. In this case, the battery will be in under
voltage protection because of the over-discharge of the battery.
The simple calculation method of battery current is: load power divided by battery voltage.
Due to the consumption of the inverter itself, the actual current will be about 10% larger. For
example, the voltage of battery is 12VDC, and load power is 1000W, therefore, the actual
current of the battery is about 1000W÷12V×110%≈91.6A.
2) Battery operating time
Battery operating time depends on battery capacity and current, and the calculation
formula of operating time is: battery capacity÷current=battery capacity÷(the load
power÷battery voltage×110%). For example, battery specification is 12V, 2000Ah, load
power is 1000W, so the total discharging time is 2000Ah÷(1000÷12×110%)≈21.8 hours.
Note:
The result of formula above is on the basic of discharging rate of 20 hours of the
battery, that is, the result is from the discharging current of 2000Ah battery not exceed
100A. When the charging current exceeds this value, the discharging period will reduce.
And the quantity of the electricity of the battery may also influence the result. Please refer to
the specification of the battery manufacturer.
F. CONNECTION
1) Grounding
The power inverter has a terminal on the rear panel marked " Grounding "or " ". This is
used to connect the chassis of the power inverter to the ground. The ground terminal has
already connected to the ground wire of AC output receptacle through the internal
connecting wire.

6
The ground terminal must be connected to the ground wire, which depends on where
the power inverter is installed. In a vehicle, connect the ground terminal to the chassis of
the vehicle. In a boat, connect it to the boat's grounding systems. In a fixed location,
connect the ground terminal to earth.
Warning:
● To make sure the firmness of the connection. The ground wire must be 14AWG
2
(2.08mm ) or even larger.
● Do not operate the power inverter without connecting to the ground. Electric shock may
be resulted.
2) Connect to the battery
(1) Please do all the safety precautions before connection, and then check whether the
battery voltage is in accordance with the input voltage of the inverter. Only the voltage
of the battery accords with the requirements can be allowed to connect with the
inverter.
(2) The connecting wire must bear enough current. Depending on the table below, please
choose the input DC wire or larger one.
Note:
(1) The table above is only for your reference. In practice, the thick wire can be replaced
by two thin parallel wires if only the total cross-sectional area of the wire meets the
requirements.
(2) In high current, the input DC wire may produce voltage drop, therefore, the operating
voltage should be subject to the value on the terminals. If the voltage drop is too large,
you can increase the cross-sectional area or reduce the length of the lead.
(3) Connect cathode wire of the battery to the cathode terminal (black) on the rear panel
of inverter and then connect the anode wire of the battery to the anode terminal (red)
on the inverter, and fix them.
Warning:
(1) Please wear eye patch and work clothes when working around the battery to protect
your eyes and skin from the acid and corrosive objects.
