1.The switch is off.
2.Loose connection
Disturbance
Recharge or replace the battery.
1. Turn on the power switch.
2. Check the connections.
1. Keep the inverter far from antenna.
2. Use screened antenna.
No output voltage
Incorrect output
voltage
Cannot power the
load
When using with TV
or
audio, there is
snowflake on the
screen or noise from
the audio.
1.Load power is too large, or
the actual power of the
appliance exceeds nominal
power.
2 .T h e s t a r t i n g p o w e r o f
appliance is larger than the
rated power(such as motor)
1.Measure using true RMS
multimeter.
2.The battery power of RMS
Multimeter is low.
3.The input voltage is too
high or too low.
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.
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.
Reduce the load power.
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.
If the unit still doesn't work normally after using all the methods above, it maybe
the internal faults of the circuit. Please call or email AIMS power at (775)359-6703 ext

11. Protection
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 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(32V/62V).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 to 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
(1) The parameter in the brackets above are for inverters with input voltages of
24V/48V.
(2) 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.
