Description
Specifies whether the inverter output has a neutral wire
based on the application scenario.
Specifies whether to allow the inverter to automatically
start after the power grid recovers.
Specifies the time after which the inverter begins
restarting after the power grid recovers.
The standards of certain countries and regions require
that after the inverter shuts down for protection due to a
fault, if the power grid voltage is higher than Grid
reconnection voltage upper limit, the inverter is not
allowed to reconnect to the grid.

that after the inverter shuts down for protection due to a
fault, if the power grid voltage is lower than Grid
reconnection voltage lower limit, the inverter is not
allowed to reconnect to the grid.

Specifies whether to enable the quick startup function
after the power grid recovers from a short-time
disconnection.
