10. Protection
Features
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 a computer.
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.
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.
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, 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.

Recharge or replace the battery.
1. Do not use when the battery is
charging.
2. Check the rated voltage of the
battery and make sure that it is
in the allowable range of the
input voltage.
Reduce the load power.
1. Cut off the load and allow to cool
for 10 to 30 minutes. Restart
after it reaches normal
temperature.
2. The load power is too large.
Reduce the total load power to
the range of rated power.
3. Avoid blocking the vent and
improve the ventilation
condition.
4. Reduce the ambient
temperature.
1. Turn on the power switch.
2. Check the connections.
1. Use a true RMS multimeter to
measure, such as model FLUKE
177/179.
2. Change the battery of the
multimeter then test again.
3. Try to maintain the input voltage
in the range of rated power.
Reduce the load power, or turn
the appliance on first, then open
the inverter. Use the internal soft-
start circuit of the inverter to
buffer the start.
1. Keep the inverter far from antenna.
2. Use screened antenna.
