Description
Specifies the time after which the inverter begins restarting after the power
grid recovers.
According to the standards of certain countries and regions, after the
inverter is powered on for the first time for grid connection, if the power
grid voltage is lower than Startup voltage lower threshold of grid
connection, the inverter is not allowed to connect to the grid.
According to the standards of certain countries and regions, after the
inverter is powered on for the first time for grid connection, if the power
grid voltage is higher than Startup frequency upper threshold of grid
connection, the inverter is not allowed to connect to the grid.
According to the standards of certain countries and regions, after the
inverter is powered on for the first time for grid connection, if the power
grid voltage is lower than Startup frequency lower threshold of grid
connection, the inverter is not allowed to connect to the grid.
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.

Specifies the voltage threshold for triggering reactive power compensation
based on the cosφ-P curve.
Specifies the voltage threshold for exiting reactive power compensation
based on the cosφ-P curve.
