7. USAGE OF INVERTER
①
How to use a inverter
1) Check the output voltage and capacity of the battery to make sure it applicable to the
requirement of the product use.
2) Connect the battery and the DC cable of the inverter to ensure that the polarities do
not be reversed and in good contact.
3) Long press the switch of inverter or of remoter for over 0.5s and later on let it go, if
the indicator lighter on the inverter or on the remoter box is on, it means that the
inverter start to work normally. This method can avoid effectively turning on the unit
due to the interference or any mistakes.
4) Switch off electrical appliances and put electrical appliance plug to the AC output
socket of inverter. And then switch on electrical appliance for using.
5) The cooling fans inside the inverter do not work when the unit power on. It doesn't
run until the case temperature rise up to 40
℃
.
6) Switch off inverter and remoter to stop working. At that time, the indicator lights in
both inverter and remoter are off. The inverter does not consume current from
battery when it switched off

How to use USB outlet
The USB outlet can provide stable 5V DC voltage; the maximum current is
1000mA(2100mA), which can directly provide power for the portable device with USB
port.
Notice:
Before use the USB power supply, please make sure the device can be
charged by USB and the maximum working current is no more than 1000mA(2100mA).
8. OPERATIONAL PRINCIPLE
：
The inverter converts DC to AC, conversion process is divided into two steps, the first
step is to convert low voltage DC to high voltage DC , the second step is using the full
bridge converter tech to convert high voltage direct current into alternating current.
The conversion circuit adopts advanced power device and high frequency power
conversion technology. Compared with the traditional inverter using the power
frequency transformer, it has the characteristics of small size, light weight and high
conversion efficiency etc

9. OUTPUT VOLTAGE AND WAVE FORM:
The output wave form for this inverter is Pure Sine Wave, which is much like even
more pure than the one from utility-supplied AC electricity; pure sine wave is applicable
in lots of loads, such as Linear Adaptor, switching power supply, transformer, motor and
so on.
Comparing with Modified wave form, for inductive loads such as refrigerator and
electric fans, pure sine wave form can improve its power factor and the battery use ratio
and reduce effectively working noises from appliances. For sensitive loads such as
adapter of lap-top, pure sine wave can low down the rush current at working and
reduce interferences to increases reliability and the life of the product.
1) Fixed on the plane with an opening, four screws can be fixed directly on the four
mounting holes of the remote control box.
2) Connect the remote control cable between the box and the inverter.

8) Although there is over-voltage protection, it may also cause damage of the inverter if
the input voltage is too high.
3. Connection of the AC appliance
Put the power plug of the AC appliance load into the output AC receptacle of the
inverter directly.
Warnings:
1. Make sure that the switches of the inverter and appliance power are in OFF position
before connection.
2. Check the power cord. If it is damaged, it should be connected after replacement.
