contact your local distributor if the problem can’t be solved by
yourself.
The following sheet lists some basic questions may encounter in the
operation.
Trouble Shooting
Alarm Message
Solution
System
Faulty
Or
Failure
Type
AC voltage &
frequency are too
high or too low.
(F00-F03)
1) Pease check mains voltage whether it is complied with
local,safety standard
2) Please check the AC output line is properly connected.
Make sure its output voltage to see if it is normal.
3) Disconnect PV input and restart the inverter and check
whether fault still exists.
4)
Contact with your local distributor if the fault still exists.
Bus voltage is too
high or too low
(F04-F05)
1) Please check the setting of input mode
2) Disconnect PV input and restart the inverter and check
whether fault still exists.
3)
Contact with your local distributor if the fault still exists.
Bus voltage is
Unbalance(F06)
1)Please check the setting of input mode.
2)Disconnect PV input and restart the inverter and check
whether fault still exists.
3)Contact with your local distributor if the fault still exists.
Insulation
impedance
Fault(F07)
1) Disconnect PV input and restart the inverter and check
whether fault still exists.
2) Please measure impedance of PV+/PV- to ground whether
is over than 500KΩ.
3) Please contact your local distributor if impedance is less
than
500KΩ.
Input Current
High
(F08)
1)
Please check the setting of input mode.
2) Disconnect PV input and restart the inverter and check
whether fault still exists.
3)
Contact with your local distributor if the fault still exists.
Hardware
Current
High(F09)
1) Disconnect PV input and restart the inverter after few
minutes and check whether fault still exists.
2)Contact with your local distributor if the fault still exists.
