Presumable
Fault
36
• Make sure the grounding connection of the inverter is
reliable.
•Make a visual inspection of all PV cables and modules.
If this fault is still shown, contact the service.
37
• Check the open-circuit voltages of the strings and
make sure it is below the maximum DC input voltage of
the inverter.
If the input voltage lies within the permitted range and
the fault still occurs, please call service.
38
•Check the PV array’s insulation to ground and make
sure that the insulation resistance to ground is greater
than 1 MOhm. Otherwise, make a visual inspection of all
PV cables and modules.
• Make sure the grounding connection of the inverter is
reliable.
If this fault occurs often, contact the service.
40
•Check whether the airflow to the heat sink is
obstructed.
•Check whether the ambient temperature around the
inverter is too high.

• Disconnect the inverter from the grid and the PV
arrays, reconnect them after 3 minutes.
If this fault is still being shown, contact the service.
