Fault
Code Message Warning Description Possible problem and solution(s)
F01 PV Over Voltage
PV voltage exceeds the
parameter
Problem
• The voltage of the solar generator is too high
Solution(s)
• Check the input voltage
• Check module wiring and system
F02 PV Over Current
PV current exceeds the
parameter
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
F04
CB10 (PV CB)
Trip PV side circuit breaker(CB10)
tripped
Problem
• CB10 disconnect switch is open
• Auxiliary switch is inoperable, K10 contactor
failed closed
Solution(s)
• Check the wiring connection
• Change the CB10, replace K10 contactor
F05
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
F06 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
