utility company first.
If the grid voltage lies within the permitted
range and this fault still occurs, please call
service.

• 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

• 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.

•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
