10. WORK INSTRUCTIONS
When the inverter is in work condition, the input voltage and output power will be
shown on the digital display screen by turns. Likewise, when the inverter goes into
protection, corresponding letters will be also shown on the screen. Different letters
mean the inverter is in different protection conditions.
1. When the input (V) LED is on, the current input voltage is shown.
2. When the output (KW) LED is on, the current output power (KW) is shown.
3. When the output (W) LED is on, the current output power (W) is shown.
4. LO means the inverter is in under voltage protection.
5. HI means the inverter is in over voltage protection.
6. OL means the inverter is in overload protection or short-circuits protection.
7. OH means the inverter is in OVER HEAT protection.
8. 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 startup 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.
9. THE 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.
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 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.

11. PROTECTION FUNCTION
1. Input under-voltage alarm:
When the input DC voltage is lower than 9.8V
/19.6V/39.2V, 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.
2. Under voltage protection:
The inverter will automatically shut down when the
input DC voltage is lower than 9.5V/19V/38V. The buzzer will whistle continuously
and the digital display screen will show LO. Please turn off the inverter and use it
after recharging the battery.
3. Over voltage protection:
The inverter will automatically shut down when the input
DC voltage is higher than 16V/32V/62V. The buzzer will whistle continuously and
the digital display screen will show HI. Please turn off the inverter and adjust the
input voltage to the admissible range.
4. Overload protection:
The inverter will automatically shut down when the load
power is higher than the rated power. The buzzer will whistle continuously and the
digital display screen will show OL. Turn off the inverter and resume to normal
operation after taking away the redundant load.
5. Short-circuit protection:
The AC output will be automatically shut down when
short circuit. And the digital display screen shows OL.
6. Thermal protection:
The unit will be calorific during operation. If the temperature is
higher than 65
℃
, the inverter will automatically shut down. Then the buzzer will
whistle continuously and the digital display screen shows OH. Please turn off the
inverter, and continue using it after the temperature goes back to normal
temperature naturally. Meanwhile find out the factors causing the fault, such as
ventilation, ambient temperature, vent, load power and so on. It can avoid the
similar things happen again.
12. QUICK KNOWLEDGE ABOUT INVERTER
! Ensure Your Battery Size Is Big Enough And Voltage Is Correct.
A. CORRECTLY CONNECTING THE INVERTER FOR FIRST USE.
1) Secure the provided Negative (black) DC cable connect to the Negative (-) bolt on
the inverter, and the other end to the Negative (-) post on the battery.
2) Secure the provided Positive (Red) DC cable to the Positive (+) bolt on the inverter,
and the other end to the Positive (+) post on the battery.
3) The nuts of the connection posts must be tightened to ensure well connected.
4) Press the power switch for one second, because it is a long press type switch.
WARNING: REVERSE CONNECTED THE CABLES WILL DAMAGE THE
INVERTER AND AVOID YOUR WARRANTY!
