2). Under voltage protection:
The inverter will automatically shut down when the input
DC voltage is lower than 9.5V for 12V model and 20V for 24V model. 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.
3). Over voltage protection:
The inverter will automatically shut down when the input DC
voltage is higher than 16V for 12V model and 32V for 24V model. 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.
4). Overload protection:
The inverter will automatically shut down when the load is
higher than the rated power. The buzzer will whistle continuously. Turn off the inverter and
resume normal operation after taking away the excessive load.
5). Short-circuit protection:
The AC output will be automatically shut down when short
circuited. It will automatically reset after the problem is solved.
6). Thermal protection:
The unit will get hot during operation. If the temperature is higher
than 149°F or 65°C, the inverter will automatically shut down. Then the buzzer will whistle
continuously and the green light is off, red light is on. Please turn off the inverter, and
continue using it after the temperature goes back to normal naturally. Meanwhile find out
the factors causing the fault, such as ventilation, ambient temperature, vent, load power
and so on. It can avoid similar things from happening again.
Notice:
In the case of over voltage, under voltage and thermal protection, the inverter will shut
down automatically after 1 minute if the user doesn't turn it off . When it is in the OFF
position, the inverter doesn't consume battery current.

6) The cooling fans inside the inverter do not work until the case temperature rises up to
about 104°F
or
40°C.
7) Switch off inverter or remote to turn off. At that time, the indicator lights for both inverter
and remote are off. The inverter does not consume current from the battery when it is
switched off.

How to use USB power supply
This model supplies a USB output, and provides stable voltage at 5V DC, maximum
current 2.1A directly to a portable device with USB port.
Notice: 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 2.1A.
8. About soft start technology
The output voltage rises up from low to normal when the inverter is turned on. This can
reduce high startup currents, which can make startup easier for large inductive loads.
As for the large inductive loads, such as electric tools and capacitive loads, we suggest
turning on the switch of the appliance firstly and then the inverter's. The soft start may be
enough to power the high startup.
9. The output wave form
The output wave form of this inverter is a Pure Sine Wave, which is similar to utility-
supplied AC electricity. Pure sine wave is applicable in most loads, including electrical
equipment, such as Linear Adaptor, switching power supply, transformer, motor and so on.
Compared to Modified wave form, for inductive loads such as a refrigerator and electric
fans, pure sine wave form can improve its power factor and the battery's efficiency and
reduce working noises. 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.

Features
1). Input under-voltage alarm:
When the input DC voltage is lower than 9.8V for 12V
model and 21.2V for 24V model, 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 a computer.
