Troubleshooting:
For red LED and protection switch.
Symptoms
Warning red LED is illuminated
And has low output voltage
The output voltage is low or has no
output voltage with small AC loads
The warning red LED illuminates
The overload alarm is beeping.
Fuse breaks
Protection switch has been tripped.
High output voltage is present
Output of the inverter has increased
drastically.
Before using the inverter with heavy motors or appliances, it is wise to verify the startup requirements. This is most often much higher than the listed
running requirements at 3 to 5 times the continuous current rating.
To keep the life expectancy of the inverter at its maximum, please ensure plenty of ventilation
Possible problem
Your device requires more power than the
inverter is able to produce. The inverter has
been overloaded.
Check the charging status of the battery with a
meter
Check the durability of the battery with a meter
Check all connections between battery and
inverter
Check for abnormalities on the devices
connected to the inverter
Check if the consumption powers of the devices
are normal with a meter.
Check all wiring connections.
Check the devices connected to the inverter
Check if the input voltage of the battery is
correct at 12V, 24V or 48V DC
Tips for improving inverter service life
Possible solution
Stop the operation of the connected devices
Use the inverter under a lower condition than
the specified output capacity (refer to
instructions)
Check to see if the battery is fully charged with
a meter.
Check to ensure the correct wire gauge is
connected between battery and inverter and AC
output.
Remove devices operating abnormally.
Check the inrush surge of all connected devices.
MAX surge ability of the inverter is 200% of
the output capacity for 500 milliseconds
Check the + (Pos.) and – (Neg.) connections are
made properly.
Make sure the connected device does not
exceed the capacity of the inverter
Turn off the devices connected to the 120V AC
output of the inverter
Check the voltage of the battery with an
external multi meter.
