Trouble Shooting
Solution
(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.
(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.
(1)Please check the setting of input mode.
(2)Please try to restart inverter every few minutes for several times
and check whether fault still exists.
(3)Contact with your local distributor if the fault still exists.
(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.
