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.
(2) Prepare enough water and soap. In case the acid material splashes on your skin, clean it by soap and
water as soon as possible. If the acid material spays to your eyes accidentally, clean it by cold water
and then sent to hospital.
(3) Do not put any combustible material in the location of installation for it will result in spark when connect-
ed to the battery.
(4) Keep good ventilation. The battery may produce a little inflammable gas when it works, so keep away
from the inverter and it is better to install them in different space.
(5) Fix the connecting wire of the input DC, or it will result in the over-reduction of the voltage or over-tem-
perature of the inverter.
(6) Reverse connection of the polarities or the short circuit will burn the fuse or result in the permanent
damage of the internal elements of inverter.
(7) Take away the metal accouterments, such as ring or watch, when installation, to avoid the short circuit.
(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 load power plug of the AC appliance into the output AC receptacle of the inverter directly.
Warning:
(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.
H. USAGE
1) How to use inverter
(1) Check the output voltage and capacity of the battery to make sure it is in accord with the requirements
of the product.
(2) Connect the battery and the DC cable of the inverter to ensure that the polarities are not connected
reversely and in tight connection.
(3) Long press the switch or the remote of inverter for over 0.5s and then stop, if the indicator light on the
inverter or on the remote control box is on, it means the inverter starts to work normally. This opening
method can avoid turning on the unit by mistakes due to the interference or any factors.
(4) Switch off electrical appliances and put its plug to the AC output socket of inverter. Then switch on
electrical appliance.
(5) The cooling fans inside the inverter do not work until the case temperature rises up to about 104°F or
the load power is more than 640W.
(6) Switch off inverter and remote to stop working. At that time, the indicator lights in. Both inverter and
remote controller are off. The inverter does not consume current of the battery when it is switched off.
2) How to use USB power supply
This model with USB output, can provide stable voltage 5VDC, maximum current 2.4A directly for the
portable device with USB port.
Note: Before using the USB power supply, please make sure the device can be charged by USB and the
maximum working current is no more than 2.4A.
I. ABOUT SOFT START TECHNOLOGY
The output voltage rises up from low to normal when the inverter is turned on. This can reduce attack of
high start-up currents, which can make startup easier of large inductive loads. As for the large inductive
loads, such as electric tools and the capacitive loads, suggest turning on the switch of the appliance firstly
and later the inverter's. The soft start works.
J. OUTPUT WAVE FORM
The output wave form of this inverter is Pure Sine Wave, which is much like the one from utility-supplied
AC electricity, even more purer; pure sine wave is applicable in most of loads, including electrical
equipments, such as Linear Adaptor, switching power supply, transformer, and motor and so on. Compar-
ing 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's efficiency and reduce working noises effectively from
appliances. For capacitive loads such as adapter of lap-top, pure sine wave can lower the rush current at
work and reduce interferences to increase reliability and prolong the life of the product.
K. WORK INSTRUCTIONS
When item is working, the power indicator on inverter will be on, and the LCD remote controller will show
battery status, input voltage, and output wattage. When item goes into protection, the protect indicator on
inverter is on, and the LCD remote controller will show the following code:
(1) Warning Sign and IN: LOW is on: Input Low Voltage Protection
(2) Warning Sign and IN: HIGH is on: Input High Voltage Protection
(3) Warning Sign and OVERLOAD is on:Overload Protection or Short-Circuit Protection
(4) Warning Sign and Thermometer Sign is on: Overheat Protection
