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 inverter.
If this fault is still being shown, contact the service.
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
