Inverter grid parameter setting: voltage protection
Tap ‘Grid Voltage Protection’, the next page will display the parameters.
There are three threshold levels for the overvoltage and undervoltage protection. The first threshold means the smallest
range, and the third threshold means the largest range.
All thresholds need to follow the principles as below:
1.
The first maximum threshold ≤ The second maximum threshold ≤ The third maximum threshold
2.
The first minimum threshold ≥ The second minimum threshold ≥ The third minimum threshold
3.
The first threshold tripping time ≤ The second threshold tripping time ≤ The third threshold tripping tim
