Fault Code Descriptions
152607 4–5
0013 AC Voltage High S This fault indicates that the utility
grid voltage is above or rose above
the maximum allowed value of 110%
of nominal Vac for greater than 2
seconds, or 137% of nominal Vac for
greater than 2 cycles. This fault is
auto-clearing. Once the Utility grid
voltage has recovered within the
acceptable operating range, the
PV225S will qualify the value and
automatically clear this fault and
resume normal operation after
5 minute delay period.
• Utility grid voltage rose
above the allowable
limit
0014 Grid Interface Failed S This fault indicates that the PV225S
has detected an imbalance of AC
output power of 5kW or greater when
compared to the DC input power for
more than 6 seconds. This normally
means that the connection of the
PV225S to the grid has failed.
• K1 was opened while
the PV225S was
processing power
• K1 is inoperable
• K3 is inoperable
• SSR1 is inoperable
• TS1 or TS2 is open
0015 Grid Disconnection S This fault indicates that the PV225S
has detected a sudden AC voltage
increase of greater than 40% of the
nominal peak-to-peak value. This
normally is the result of a sudden
disconnection from the Utility grid
while the PV225S was processing
power.
• S1 was opened while
the PV225S was
processing power
0016 DC Contactor
Circuit
S This fault indicates that upon entering
the Power Tracking State, the
PV225S has detected that the PV
voltage has remained above the PV
Start Voltage threshold even after
commanding the DC contactor to
close. This condition is indicative of a
DC contactor circuit failure.
• K2 is inoperable
• SSR2 is inoperable
• TS1 or TS2 is open
