Fault Code Descriptions
152607 4–11
XX61 Right Matrix
Temperature
S This fault indicates that the PV225S
has detected that the temperature of
the right IGBT matrix aluminum
heatsink has exceeded the maximum
allowed value of 95 °C.
• Fuses F15 or F16 blown
• External cooling fan
inoperable
• Air flow on heat sink
impeded due to
accumulation of debris
• Operation above rated
ambient temperature for
an extended period of
time
0070 Interlock Activated H This fault indicates that the PV225S
has detected that the door of the Main
Inverter Enclosure is open and the
door interlock switch is in the active
position. This fault is primarily for
personnel safety. Opening the door of
the Main Inverter Enclosure while the
PV225S is processing power will
cause an immediate orderly shutdown
of the system.
• Door is open and
interlock switch is
active
• Interlock switch is
inoperable
• P2 or P3 on CCU2 is
loose or disconnected
• CCU2 ±15Vdc Power
Supply is defective
0071 PV Switch Open H This fault indicates that the PV225S
has detected that the DC Disconnect
Switch (S2) is open and the auxiliary
switch is in the active position. This
fault is primarily for personnel safety.
Opening the DC disconnect switch
while the PV225S is processing
power will cause an immediate
orderly shutdown of the system.
• DC disconnect switch is
open and auxiliary
switch is active
• Auxiliary switch is
inoperable
• P2 or P3 on CCU2 is
loose or disconnected
• CCU2 ±15 Vdc Power
Supply is defective
0075 Shutdown Rem otely S This fault indicates th at the PV225S
has detected that the system was
commanded via the GUI to transition
to the Shutdown State. This fault is
not indicative of a failure or
malfunction, but primarily used to
disable the system remotely.
• Remote Shutdown
command via the GUI
