Fault Code Descriptions
152607 4–7
XX32 Right Matrix Over
Current
S This fault indicates that the PV225S
has detected that the AC current on
one or more phases of the inverter
output has exceeded the maximum
allowed value of 712 A
rms
.
The first two digits of the fault code
indicate the particular phase where
the over current occurred as follow:
• 0132 - Matrix over current in
phase A
• 0232 - Matrix over current in
phase B
• 0432 - Matrix over current in
phase C
If more than one phase faults
simultaneously, the two first digits
are added in hexadecimal form to
indicate an over current condition in
more than one phase, thus the error
code will contain the summation of
the faulted phases.
• CT4, CT5, or CT6 are
inoperable
• CCU2 ±15Vdc Power
Supply is defective
• P3 on CCU2 is loose or
disconnected
• AC system wiring short
0033 Ground Over
Current
S This fault indicates that the PV225S
has detected that the ground fault
current has exceeded the maximum
allowed value. This maximum
allowed value for ground fault current
is a user-configurable setting with a
range of 1 to 20 Adc. The default
setting for this value is 10 Adc.
• CT8 is inoperable
• CCU2 ±15 Vdc Power
Supply is defective
• P3 on CCU2 is loose or
disconnected
• Ground -to-AC or
DC-to-System wiring
short
0040 Programming
Software
S This code indicates that the PV225S
has detected that the system is in
Programming mode. This fault does
not indicate any malfunction with the
PV225S, but is merely an indication
that the system software is in the
process of being downloaded into the
EEPROMs of the CCU2.
