Inverter grid parameter setting: reconnection time

Tap ‘Reconnection Time Settings’, the next page will display the parameters.
The observation time during which all the voltage and the frequency values are observed to be within a specified range

prior to the inverter connection or reconnection to the grid can be set in this page.
