If the insulation fault occurs frequently and lasts for a long time, the insulation resist-
ance of the PV system must be checked; possible causes of the fault could be defec-
tive PV cables or MC4 connections.
If this error occurs frequently, check the measured values of the AC network (fre-
quency, voltage, current) on the display.
Check that the DC current is within the maximum limits and check the connection to
the MPPT inputs. If no troubleshooting is possible, contact REFU Service.
