TROUBLESHOOTING TIPS
Fault / Display Cause Solutions
No output voltage, buzzer sounds
continuously
Low input DC voltage Recharge or replace the battery
Do not use it when the battery is charging.
Check the rated voltage of the battery and
make sure it is in within the range of the input
voltage.
High input DC voltage
Overload Reduce the load.
Over temperature
Cut off the load and let cool for 10 to 30
minutes. Restart it after it resumes to normal
temperature
. The load is too large, reduce
the total load to the range of rated power.
Avoid blocking the vent and improve the
ventilation condition
. Reduce the ambient
temperature .
No output voltage
The switch is off Turn on the power switch.
Poor cable connection
Check the cables and make sure they are
tightly connected
.
Incorrect output voltage
RMS Multimeter measurement error
Use a true RMS multimeter to measure , such
as model FLUKE 177/179.
The battery power of
RMS Multimeter is low.
Try to maintain the input voltage in the
range of rated power.
The input voltage
may be too high or too low.
Change the battery of the multimeter then test
again
.
Cannot drive the load
Load power is too large , or the
actual power of the appliance
exceeds nominal power
.
Reduce the load , or turn on the
appliance first , then turn on the inverter.
The starting power is larger than
rated power (such as motor). The internal inverter soft-start circuit will buffer
starting the appliance.
