The power grid voltage has exceeded the upper threshold, or the overvoltage duration has exceeded the value specified by HVRT (High Voltage Ride Through). This indicates an unstable or excessively high grid supply.
Click steps to track your progress.
Check whether the grid voltage is within the acceptable range.
Log in to the mobile phone app, SmartLogger, or NMS to modify the grid overvoltage protection threshold with the consent of the local power operator.
Check whether the peak voltage of the power grid is too high.
