Operation Instruction:
Connect the storage battery with the power inverter & battery charge:
Connect the positive terminal (red terminal) of the storage battery with the positive terminal (red
terminal) of the inverter, using the red cable. Then connect the negative terminal (black terminal) of
the storage battery with the negative terminal (black terminal) of the inverter using the black cable.
Once connected, please tighten the screws to avoid loose connections.
Connect power converter with appliances:
Before connecting the appliances, please turn the switch of the converter off, and confirm that your
connections are all correct. Connect the appliance to the output socket of the inverter, turn on the
power and check that the green indicator lights come on. The AC voltage clock should display
either 110V or 220V, which means the inverter is in normal working condition. At this time, you
can turn on the power of the appliance and the appliance will then be in working condition.
Connect power inverter with AC:
After confirming the good connection, AC voltage should be flowing as normal now. The inverter
will convert the DC to AC output automatically, at the same time supplying charge to the storage
battery. The figure on the AC voltage clock should remain at 110V or 220V.

Function Introduction
Inverter output function: Open the switch of the front panel, the inverter will convert the battery's
DC power to pure sine wave AC, output from the AC outlet on the rear panel.
Over-voltage protection function: When the battery voltage is higher than the set value, the device
will automatically cut off the inverter output when the front panel LED will flash 3 times per
second and the buzzer alarm will sound. When the voltage drops to the “over-voltage recovery
point”, the inverter will start to work again.
Under-voltage protection function: When the battery voltage drops below the set value, the device
will automatically cut off the inverter output when the front LED will flash 1 time per second and
the buzzer alarm will sound. When the voltage raises to the “voltage recovery point”, the inverter
will start to work again.
Overload/Short circuit protection: If the load e ceeds the rated power or a short circuit occurs, the
front panel LED will blink 2 times per second and the buzzer alarm will sound. When this state
occurs, the unit cannot restore itself. Turn off the power switch, check to see if the short-circuit did
occur and check whether the load is within the allowable range, then turn the power switch back on
to restore inverter output.
Fan, automatic control and thermal protection: If the machine internal temperature reaches the set
point, the unit will automatically start the cooling fan. If the temperature then becomes too high, the
device will automatically cut off the inverter output, the front LED will blink 2 times per second
and the alarm buzzer will sound. This state does not self-recover, so turn off the machine and leave
it off until the temperature of the machine drops down, then turn on the switch, restoring inverter
output.
Reverse battery protection function: The device has complete reverse battery protection, which
means that if the batteries polarities are hooked up incorrectly, the fuse in the unit itself will be
automatically blown to prevent damage to the battery itself and also to your devices. Your devices
and batteries will be safe, but the inverter itself will not be operational.
Protection Functions
Lacking-voltage Alarm: When input DC voltage is at 9.5V ~ 11V, buzzer alarm will sound and the
green LED light will flash slowly. This means that the accumulator will need to be charged.
Low-voltage protection: When input DC voltage is below 9V ~ 10.5V, buzzer alarm will sound and
the green LED light will flash quickly The power inverter with the battery charge will cut off
power automatically, protecting your battery for damage caused by e cessive discharge.
Over-voltage protection: When input DC voltage is over 15V, buzzer alarm will sound and the green
LED light will flash quickly. The power inverter with battery charge will cut off power
automatically to protect the inverter.
Anti-polar protection: The fuse will be burned out if the inverter is connected to the wrong
polarities on the battery. In this case, you should turn off the inverter power switch and change the
battery connection cable. The fuse in the inverter will need to be replaced with a fuse of the same
specification.

Overload Protection: When the load is over the rated power, the buzzer will sound after 3 to 5
seconds, and the green LED light will flash quickly. The power inverter will cut off automatically
to protect the inverter.
Short-circuit Protection: When the load is more than 2 times the rated power or the unit is in short
circuit, the buzzer will sound after 1-2 seconds and the green LED light will flash quickly. The
power inverter with the battery charge will cut off power automatically to protect the unit.
Temperature Protection: When the item is working and the temperature is over 60C – 70C, the
buzzer will sound immediately and the green LED light will flash quickly. The power inverter
charge will cut off output to protect your unit.
AC input low voltage Protection: When the AC input voltage is lower than 150V, the inverter will
cut off AC output automatically, at the same time it will stop charging the storage battery. The
yellow indicator will be off, and if the power switch on the item is on at this time, it can convert the
output automatically, so it will be convenient and supply a steady stable voltage still.
AC input over voltage protection: When the AC input voltage is higher than 250V, the inverter will
cut off AC output automatically, at the same time it will stop charging the storage battery. The
yellow indicator will be off, and if the power switch on the item is on at this time, it can convert the
output automatically, so it will be convenient and supply a steady stable voltage still.
ATTENTI N: If the low voltage protection, over voltage protection, overload protection, short-
circuit protection or temperature protection actions occur, the unit will need to be restarted. This
allows the protective measures to be reset so that they can continue to protect your equipment.
CH SING A P WER C NVERTER
All electronic products should have their rated power indicated on their labels. The rated power
should be less than the rated power of the power converter.
The method of how to estimate the power(W): the total of the load power should be equal to the
rated power(W) of the power inverter.
For e ample, you use two computers (250W 2), a light bulb (60W), a TV (200W), a fan (180W) all
at the same time.
Their total power is 250W + 250W + 60W + 200W + 180W = 940W. You will therefore need a
power inverter with a rated power of 1000W with battery charge.
CH SING A ST RAGE BATTERY
You must choose a storage battery that accord with DC input voltage that can supply enough
working current (not less than the full load input DC current of the power inverter with battery
charge). For a power inverter with battery charge of 12V-220V-2000W, you should choose a
storage battery that's more than 200AH.
Rated Power(W) (VA=W)
------------------------------------ x 1.2=?A(A or AH)
Input voltage (such as 12V)

You can calculate the storage battery's used time by this formula:

--------------------------------------------------------- x 80% = Usage Time (Hours)

The use time of the storage battery is determined by the quality of the storage battery and how long
it has been since the battery was purchased.
