Faults
Code Message Warning description Possible problem and solution(s)
1 PV Over Voltage PV voltage exceeds the param-
eter
Problem
• The voltage of the solar generator is too
high
Solution(s)
• Check the input voltage
• Check module wiring and system
2 PV Over Current PV current exceeds the parame-
ter
Problem
• The current of the solar generator is too
high
• PV system wiring short
Solution(s)
• Check the input current
• Check module wiring and system
4 CB10 (PV CB) Trip PV side circuit breaker (CB10)
tripped
Problem
• CB10 disconnect switch is open
• Auxiliary switch is inoperable, CB10 con-
tactor failed closed
Solution(s)
• Check the wiring connection
• Change the CB10, replace CB10 contactor
5 PV Polarity Failure Polarity (+, -) of PV side is
reversed Problem
• Polarity of PV side is reversed
Solution(s)
• Check the wiring connection and change
if necessary
6 Ground Fault PV side ground fault Problem
• DC & ground are shorted causing the
GFDI fuse to open
Solution(s)
• Check the solar generator for a ground
fault and Replace the GFDI Fuse
10 Inv. Over Voltage Over voltage on the inverter side Problem
• The inverter voltage is too high
Solution(s)
• Check the inverter voltage
• Check the inverter parameter
