Solution
F00-F03
AC voltage &
frequency
are too high or too low.
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.
F04-F05
Bus voltage is too
high or too low.
1.Please check the setting of input mode
2.Disconnect PV input and restart the inverter
and check whether fault still exists.
F06
Bus voltage is
Unbalance
1. Please check the setting of input mode.
2.Disconnect PV input and restart the inverter
and check whether fault still exists.
3. The fault still exists after the restart. Please
contact the dealer
