Grid undervoltage,
The grid voltage is
lower 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 lower than
the set value.
2. Check whether the protection parameters
are appropriately set via the App or the LCD.
3. Check whether the AC cable is firmly in
place.
4. If the fault is not caused by the foregoing
reasons and still exists, contact SUNGROW.
