Grid overvoltage

Generally, the inverter will be reconnected to the

grid after the grid recovers. If the alarm occurs

frequently:

1. Measure the grid voltage, and contact the local

utility grid company for solutions if the grid voltage

exceeds the specified value.

2. Check, through the App, whether the protection

parameters are appropriately set.

3. Check whether the cross-sectional area of the

AC cable meets the requirement.

4. If the alarm persists, contact SUNGROW.

004

Grid

undervoltage

Generally, the inverter will be reconnected to the

grid after the grid recovers. If the alarm occurs

frequently:

1. Measure the grid voltage, and contact the local

utility grid company for solutions if the grid voltage

is below the specified value.

2. Check, through the App, whether the protection

parameters are appropriately set.

3. Check whether the AC cable is firmly in place.

4. If the alarm persists, contact SUNGROW.
