• Disconnect the inverter from the utility grid
and the PV array and reconnect it after LED turn
o.
If this fault is still being displayed, contact the
service.
• The ambient temperature is too low to start
the inverter.
• Check if the grid is abnormal.
Restart the inverter and wait until it functions
normally.
Contact customer service if error warning con-
tinues.
• Check the grid and EPS frequency and observe
how oten maor uctuations occur.
Contact customer service if EPS frequency ab-
normal.
I this ault is caused by reuent uctuations, try
to modify the operating parameters after infor-
ming the grid oerator rst.
• Check the grid voltage and grid connection on
inverter.
• Check the grid voltage at the point of connec-
tion of inverter.
If the grid voltage is outside the permissible ran-
ge due to local grid conditions, try to modify the
values of the monitored operational limits after
inorming the electric utility comany rst.
If the grid voltage lies within the permitted range
and this fault still occurs, please call service.
