0004H Power grid voltage out of range.
The most likely reason is a Power grid outage. Account should be taken of the fact that alarms are added
together. Therefore, when this failure occurs, the alarm shown will be 0006H, the result of adding 0002H
+ 0004H.
When the Power grid returns to normal, the inverter will start operating again. If this is not so, then check
the connection lines to the Power grid.
If the Power grid quality parameters are adequate, then inspect the connection lines to the Power grid.
If the error persists, contact your installer.
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 Start 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 Start/Stop option and
click OK to change from one status to the other.
The following message will be displayed:
Go to the main menu and highlight the Run Stop option Start/
Stop and click OK to change from one status to the other.
