Inverter
failure
Over
Temperature
1.
The internal temperature is higher than specified normal
value.
2.
Reduce the ambient temperature by shading or
ventilation improvements or move inverter to cooler
place.
3.
If this is not effective, a temperature sensor may be
faulty. Contact your inverter service representative.
PV Over
Voltage
1.
C
Check the PV open-circuit voltage. This should be
less than 500VDC.
2.
I
If the PV voltage is much less than 500VDC (e.g.
<430V), measure the DCV by multi-meter, compare
the readings on meter and LCD.
If the readings differ by >5%, contact your inverter
service representative.
Device Fault
1.
This is caused by an inverter malfunction.
2.
Disconnect PV (+) or PV (-) from the input, start the unit
again.
3.
If it does not work, contact your inverter service
representative.
Consistent or
Mismatch
Fault
1.
This is caused by inconsistent values between the main
(master) and redundant (slave) controllers of the inverter.
2.
Disconnect PV (+) or PV (-) from the input, start the unit
again.
3.
If this does not work, contact your inverter service
representative.
