Warning:
This manual contains important safety and
operating instruction. Please read it carefully before
use
ing.
If the inverter still doesn't work after trying above measures, there may
be some faults in the circuit. Please return it to the supplier for
maintenance.
L. FAILURE GUIDELINES
No output voltage,
buzzer sounds
continuously
Incorrect output
voltage
Cannot drive the
load
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. Turn on the power switch.
2. Check the cables and make sure they
are tightly connected.
1. Use a true RMS multimeter to measure,
such as model FLUKE 177/179.
2. Try to maintain the input voltage in the
range of rated power
3. Change the battery of multimeter then
test again.
Reduce the load power, or turn on the
appliance first, then turn on the inverter.
1. The switch is off.
2. The battery lead
isn't connected well
1. RMS Multimeter
measurement error
2. The battery power
of RMS Multimeter
is low.
3. The input voltage
is too high or too low.
1. Load power is too
large, or the actual
power of the
appliance exceeds
nominal power.
2. The starting power
is larger than rated
power (such as
motor).
The internal inverter soft-start circuit will
buffer starting the appliance.
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.
No output voltage
Low input DC voltage
High input DC
voltage
Overload
Over temperature
Recharge or replace the battery
Reduce the load power.
