1) Input Under-voltage Alarm: When the input DC voltage is lower than 9.8V, the
buzzer will whistle intermittently to remind that the inverter will go into the under
voltage protection. Pay attention to save the data if you are using computer.
J. Protection Features
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. 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's efficiency and reduce working noises
effectively from appliances. For capacitive loads such as adapter of laptop, pure sine
wave can lower the rush current at work and reduce interferences to increase
reliability and prolong the life of the product.
I. OUTPUT VOLTAGE AND WAVE FORM
The soft start technology in this inverter protects the unit from delivering too much
AC power at once by gradually increasing the AC voltage pushed out. To make sure
that this feature works, turn on the appliance being used before turning on the
inverter. This is especially necessary for equipment that has an inductive load or
electrical motor.
H. SOFT START TECHNOLOGY
For example, using the numbers from above, the battery specification is
1 2 V, 2 * 1 0 0 A h c a p a c i t y a n d t h e l o a d i s 3 0 0 W. Ta k e b a t t e r y c a p a c i t y
200Ah*12V/300W≈8 hours. This operating time will fully deplete the battery, it is NOT
recommended. Deep cycle batteries last longer when they are only depleted to 50%
of capacity.
Battery operating time depends on battery capacity and load. The formula for
operating time is: battery capacity*battery voltage/load.
G. BATTERY OPERATING TIME
8) The Type-A, Type-C USB Port on this unit provides a stable 5V/3.6A, 9V/2.5A,
12V/2A DC current. Before using it, be sure the maximum operating current of your
device does not exceed the corresponding voltage and current mentioned above.
3) Over-voltage Protection: The inverter will automatically shut down when the input
DC voltage is higher than 16V.The buzzer will whistle continuously and the green
light is off, red light is on. Please turn off the inverter and adjust the input voltage to
the admissible range.
2) Under-voltage Protection: The inverter will automatically shut down when the input
DC voltage is lower than 9.5V. The buzzer will whistle continuously and the green
light is off, red light is on. Please turn off the inverter and use it after recharging the
battery.

F. USING THE POWER INVERTER
1) Check the output voltage and capacity of the battery. The battery(s) should match
the voltage of the inverter and have enough capacity for the load.
2) Connect your inverter to your battery bank and do not to reverse the polarities of
the connection.
3) Press the power switch button on your inverter and a green LED will light up
indicating that the inverter is on.
4) Before plugging anything into your inverter, make sure the appliance you are trying
to power is shut OFF, then plug it into the AC outlet of your inverter and power on
your appliance.
5) Once finished using the inverter, turn off your electrical appliance and the inverter.
The indicator lights should be off.
6) The cooling fans inside the inverter do not work until the case temperature reaches
approximately 104
.
°F
7) If you do not plan to use the inverter for a long period of time, disconnect it from
your battery bank. Leaving the inverter on and connected for long periods of time
may harm the equipment and over discharge the battery.
