9 Troubleshooting
If the system fails to operate properly after having the installation and setup of the system thoroughly re-
examined, use the following troubleshooting table to determine the probable cause(s) and solution(s) to resolve
error conditions. For unlisted error conditions, please contact your local dealer for technical assistance.
Error Condition Possible Cause Recommendation
Improper position of nylon guide pin.
Refer to Section 3.1 to insert the nylon guide pin
to correct position.
Inverter module cannot
be properly inserted.
Insertion of non-inverter module.
Check if the inserted module is not inverter
module. Inverter shelf holds only inverter
modules.
Lack of input power.
Ensure input cables are all firmly connected to
power source.
Check if power source is not yet switched on, or
is low in power.
No AC output
and all LEDs off.
Mismatch of inverter modules.
Ensure inserted inverter modules have the same
specifications.
No AC output.
Both green and yellow
LEDs flicker.
Inverter self-diagnosis.
Inverter self-diagnosis takes a few seconds.
LED turns to a solid green light after the
completion of self-diagnosis.
No AC output.
Both yellow and red
LEDs are on.
Load exceeds 125%.
Ensure the load is no higher than 100% of the
total power rating. Reduce as required.
1. Input wiring is connected in reverse (i.e.
reverse polarity).
Ensure input cables are connected to correct
polarity (positive to positive, negative to
negative).
2. Output voltage is out of operating range.
Adjust voltage to ensure that the connected
device is within the inverter output voltage range.
3. Inverter output is shorted.
Turn off the input power source to remove all
short circuits.
No AC output.
Red LED is on.
4. Negative Power Protection.
For multi-shelf system , any jumper insertion on
JP2 connector would obstruct parallel
connections. Remove jumper from JP2
connector.
For single-shelf system
, jumper on JP2
connector pools two inverter modules. Ensure
there is a jumper on JP2 connector.
1. Inverter fails to soft start.
Reboot the inverter system by switching off and
on the input power source.
Red LED blinks fast.
2. Inverter temperature rises beyond the
temperature limit.
Leave inverter idle to cool down for few minutes.
AC output exists with
yellow LED flickering.
Input voltage is out of operating range. Ensure input voltage is between 45 to 58Vdc.
AC output exists and
yellow LED is on.
Load is over 100% but below 125%.
Ensure the load is no higher than 100% of the
total power rating. Reduce as required.
Failure of EEPROM.
Reboot the inverter system by switching off and
on the input power source.
Inverter continuously
delivers power, but with
red LED flickering
slowly.
Fans failure.
Check if the fans are locked or fail to work.
If fan is locked, remove the obstruction;
if fan fails to work, replace the fan.
