operating instruction. Please read it carefully before use
the unit.
No output voltage,

Incorrect output
voltage
Cannot drive the
load
1. Do not use when the battery is being
charged.
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 connections and make sure
connect well.
1. Use a true RMS multimeter to measure,
such as model FLUKE 177/179.
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, or turn on the
electrical appliance, then turn on the
inverter. Use the internal soft-start circuit of
the inverter to buffer the start.
1.The switch is off.
2.The battery lead
doesn’t connect well.
1. Measured using
true RMS multimeter.
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
of appliance is larger
than the rated
power(such as motor)
While using with TV
or audio, there is
snowflake on the
screen or noise
from the audio.
Disturbance 1. Keep the inverter far from antenna.
2. Use screened antenna.
1. Cut off the load and 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.
