If all of the above methods have been tried, the product still not work properly.
The internal circuit of the product may be out of order. Please return the
product to the supplier for maintenance.
Do not use it when the
battery is charging. Check
the rated voltage of the
battery and make sure that it
is in the allowable range of
the input voltage
1. The switch is off.
2. The battery lead isn't
connected well
Cut off the load and let it
cool naturally for 10 to
30 minutes. Restart it after it
resumes to normal
temperature. The load
power is too large, reduce
the total load power to the
range of rated power. Avoid
blocking the vent and
improve the ventilation
condition. Reduce the
ambient temperature.
1. Turn on the power switch.
2. Check the cables and
make sure they are tightly
connected.
Welcome to use GIANDEL power inverter. If you have any query during using our
inverter, please contact our service team by email: [email protected]
3. Overload protection(OL)n: The inverter will automatically shut down when the load
is higher than the rated power. LED display will indicate “OL”. The buzzer will
whistle continuously. Turn off the inverter and resume to normal operation after
taking away the excessive load.
4. Short-circuit protection: The AC output will be automatically shut down when short
circuited. And LED display will indicate “OL” It will automatically reset after the
problem is solved.
5. Thermal protection(OH): The unit will get hot during operation. If the temperature is
higher than 149°F, the inverter will automatically shut down. LED display will
indicate “OH”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 etc. It can
avoid similar issues from happening again.
Reduce a load power,
or turn on the appliance
first, then turn on the
inverter.
1. Use a true RMS multimeter
to measure, such as the
model FLUKE 177/179.
2.Try to maintain the input
voltage in the range of
rated power
3.Change the battery of the
multimeter then test again.
1. RMS Multimeter
measurement error
2. The battery power of RMS
Multimeter is low.
The input voltage is too high
or too low
While using with
TV or audio, there
is snowflake on
the screen or noise
from the audio.
1. Keep the inverter far from
antenna.
2. Use screened antenna.
