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. If grid phase vol-
tages differ greatly, contact the electric power com-
Grid Voltage
pany for solutions.
Imbalance
2. If the voltage difference between phases is within
the permissible range of the local power company,
modify the grid voltage imbalance parameter through
the App or the LCD.
3. If the fault still exists, contact SUNGROW.
1. Check whether the corresponding string is of re-
