• PV system wiring short

 

 

 

 

 

 

0021

PV Over-Voltage

S

This fault indicates that the PV225S

PV system wiring short

 

 

 

has detected a DC input voltage of

• Lightning strike on PV

 

 

 

greater than the maximum allowed

 

system wiring

 

 

 

value of 600 Vdc.

 

 

 

 

 

 

 

 

0023

Bus Voltage High

H

This fault indicates that the PV225S

PV system wiring short

 

 

 

has detected that the DC bus voltage

• Lightning strike on PV

 

 

 

has exceeded the maximum allowed

 

system wiring

 

 

 

value of 925 Vdc.

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.
