Faults and Warnings
6.3.2 Fault
Code Message Warning Description Possible problem and Solution(s)
1 PV Over Voltage PV voltage exceeds the param-
eter [DC over voltage Level] Possible 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 [DC over current Level] Possible 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 (DS10)
tripped Possible problem
• DS10 disconnect switch is open
• Auxiliary switch is inoperable, DS10
contactor failed closed
Solution(s)
• Check the wiring connection
• Change the DS10, replace DS10 contactor
5 PV Polarity Failure Polarity (+, -) of PV side is
reversed Possible problem
• Polarity of PV side is reversed
Solution(s)
• Check the wiring connection and
change if necessary
6 Ground Fault PV side ground fault Possible problem
• The GFDI fuse in inverter is opened
causing PV side grounding or short-
circuit fault (DC side Grounding Type)
• The unbalance of measured PV voltage
in inverter causing PV side grounding or
short-circuit fault (DC side Isolation Type)
Solution(s)
• Check the solar generator for a grounding
or short-circuit fault and Replace the
GFDI Fuse (DC side Grounding Type)
• Check the solar generator for a grounding
or short-circuit fault (DC side Isolation
Type)
