11 Troubleshooting
When the PV system does not operate normally, we recommend the following
solutions for quick troubleshooting. If a fault happens, the red LED will light up. The
corresponding causes are described in section 9.3 “Display messages”. The
corresponding corrective measures are as follows

•Check the PV generator’s insulation to earth, make sure that the insulation
resistance to earth is greater than 1 MOhm; Otherwise, make a visual
inspection of all PV cables and modules.
•Make sure the earth connection of the inverter is reliable.
If this fault occurs often, contact the service.
36
•Make sure the earth connection of the inverter is reliable.
•Make a visual inspection of all PV cables and modules.
If this fault is still shown, please call service.
46
•Check the open-circuit voltages of the strings, make sure it is lower than
the Max. DC input voltage of the inverter;
If the input voltage lies within the permitted range, and the fault still
occurs, maybe the internal circuit has broken, please call service.
37
•Check the open-circuit voltages of the strings, make sure it is lower than
the Max. DC input voltage of the inverter.
If the input voltage lies within the permitted range and the fault still occurs,
please call service.
41, 42
43, 44
•Disconnect the inverter from the grid and the PV generator, reconnect
them after 3 minutes.
If this fault is still being shown, please call service.
33
•Check the grid frequency and observe how often major fluctuations occur.
If this fault is caused by frequent fluctuations, try to modify the operating
parameters after informing the utility provider first.
35
•Check the fuse and the triggering of the miniature circuit breaker in the
distribution box.
•Check grid voltage, grid usability.
