Remark
1.
Blank form indicates mean that it should be refer to related items
2.
For example: "LINE" is ON, "INV" is OFF, "BAT" flashes for 1 second, "Load" goes off, and buzzer sounds for 1 second. IT
means In the ac output state, DC input over voltage, normal load, no over temperature
Fault Analysis Table
1.
When the inverter fails, the red signal indicator on the front panel will be “ON”
2.
According to different fault conditions appear as long and alarm or flashing.
3.
You can determine the cause of the fault by looking at the indicators on the front panel and refer to the following
figure for proper handling.
Item
Fault
Possible Reason
Solutions
1
Battery, load, over
temperature LED, 1s 1 flash
Turn off the output due to internal
overheating
1.
Check the fan is running or not
2.
Check the air vents are blocked or not
3.
The environment temperature is too high or not
4.
Reduce the load
5.
Wait 10 minutes for inverter cooling and drop of
the temperature then restart
2
The load LED Indicator ON
and the buzzer sounds
1.
Overload more than 150%
2.
Internal failure to shut down
the inverter
1.
Check whether running in overload
2.
If yes, Reduce the load and restart
3
Battery LED Indicator ON.
3s1 flash, buzzer 3s 1 sound
Input DC voltage is too lower
Check the DC input voltage is too lower and out of
the range for the inverter requirements
4
Battery LED Indicator ON.
1s1 flash, buzzer 1s 1 sound
Input DC voltage is too higher
Check the DC input voltage is too higher and out of
the range for the inverter requirements
5
Load LED Indicator, 3
seconds 1 flash, buzzer 3
seconds 1 sound
Overload 100~125%
1.
Check whether running in overload
2.
If yes, Reduce the load and restart
6
The LINE Indicator OFF
after connect with AC City
main Power
AC Mains voltage and frequency
exceed the input limited range
1.
Check if the AC mains voltage and frequency
exceed the inverter input range.
2.
Check whether the power switch on the panel is
switch on or not .
