Troubleshooting and Maintenance
9.1 Troubleshooting
Once a fault occurs in the inverter, the fault information can be displayed on the App
interface.
Fault codes and check methods are as follows:

Grid overvoltage,
the grid voltage is
higher than the set
protection value
Generally, the inverter will be reconnected
to the grid after the grid returns to normal. If
the fault occurs repeatedly:
1. Measure the actual grid voltage, and
contact the local electric power company
for solutions if the grid voltage is higher than
the set value.
2. Check whether the protection parameters
are appropriately set via the App.
3. Check whether the cross-sectional area
of the AC cable meets the requirement.
4. If the fault is not caused by the foregoing
reasons and still exists, contact SUNGROW.
003
Grid transient
overvoltage,
the transient grid
voltage is higher than
the standard value.
Generally, the inverter will be reconnected
to the grid after the grid returns to normal. If
the fault occurs repeatedly, contact
SUNGROW.
