Fault Description

Possible Causes

 

 

 

 

 

0013

AC Voltage High

S

This fault indicates that the utility

• Utility grid voltage rose

 

 

 

grid voltage is above or rose above

 

above the allowable

 

 

 

the maximum allowed value of 110%

 

limit

 

 

 

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

 

 

 

 

 

PV100S will qualify the value and

 

 

 

 

 

automatically clear this fault and

 

 

 

 

 

resume normal operation after

 

 

 

 

 

5 minute delay period.

 

 

 

 

 

 

 

0014

Grid Interface Failed

S

This fault indicates that the PV100S

• K1 was opened while

 

 

 

has detected an imbalance of AC

 

the PV100S was

 

 

 

output power of 5 kW or greater

 

processing power

 

 

 

when compared to the DC input

K1 is inoperable

 

 

 

power for more than 6 seconds. This

K3 is inoperable

 

 

 

normally means that the connection

SSR1 is inoperable

 

 

 

of the PV100S to the grid has failed.

TS1 is open

 

 

 

 

 

0015

Grid Disconnection

S

This fault indicates that the PV100S

• S1 was opened while

 

 

 

has detected a sudden AC voltage

 

the PV100S was

 

 

 

increase of greater than 40% of the

 

processing power

 

 

 

nominal peak-to-peak value. This

 

 

 

 

 

normally is the result of a sudden

 

 

 

 

 

disconnection from the Utility grid

 

 

 

 

 

while the PV100S was processing

 

 

 

 

 

power.

 

 

 

 

 

 

 

 

0016

DC Contactor

S

This fault indicates that upon entering

K2 is inoperable

 

Circuit

 

the Power Tracking State, the

SSR2 is inoperable

 

 

 

PV100S has detected that the PV

TS1 is open

 

 

 

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.

 

 

 

 

 

 

 

 

0020

PV Over-Current

S

This fault indicates that the PV100S

CT4 is inoperable

 

 

 

has detected a DC current greater

• CCU2 ±15 Vdc Power

 

 

 

than the maximum allowed value of

 

Supply is defective

 

 

 

712 Adc.

• P3 on CCU2 is loose or

 

 

 

 

 

disconnected

 

 

 

 

• PV system wiring short
