11 Troubleshooting
When the PV system does not operate normally, we recommend the following
solutions for quick troubleshooting. If an error occurs, the red LED will light up.

• 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 is within the permitted range
and the fault still occurs, it might be that the
internal circuit has broken. Contact the 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 grid operator first.
34
•Check the grid voltage and grid connection on
inverter.
• Check the grid voltage at the point of connection of
inverter.
If the grid voltage is outside the permissible range
due to local grid conditions, try to modify the values
of the monitored operational limits after informing the
electric utility company first.
If the grid voltage lies within the permitted range and
this fault still occurs, please call service.
35
• Check the fuse and the triggering of the circuit
breaker in the distribution box.
• Check the grid voltage, grid usability.
• Check the AC cable, grid connection on the
