0020H, Insulation failure in the DC circuit.
There are three possible causes:
- There is an insulation failure in the panel earthing circuit.
- The thermal fuse varistor protection has been triggered.
- The differential current or default current protective device has been triggered.
An insulation failure can be life threatening.
Only qualified personnel are authorised to repair Insulation Failures.
Procedure to determine the exact cause of the insulation failure:
- Check that the insulation failure is not in the panel circuit, by disconnecting the various panel strings from the circuit.
- If feasible, connect the inverter to another panel circuit which is functioning correctly.
- If the fault persists, then measure the voltage between each string in the panel array and earth.
- If the voltage measured is constant and more or less coincides with the open circuit voltage, then there is an earth fault in that
string. This needs to be checked for each string.
- If the fault persists after correcting the earth fault, then the thermal fuse - varistor protection needs to be checked.
In order to make this check, the equipment needs to be opened. This check should therefore be made by the installer. The Installer's
Manual explains the exact procedure
:
4.1.3 Red LED
When this LED remain on, it indicates that the inverter is in manual shutdown status.
The re-starting of the inverter is a manual operation, given the fact that the Run or Stop status does not change, even if the power
supply to the inverter is cut off.
Go to the main menu and highlight the Run Stop option MARCHA PARO and click
The following message will be displayed:
