No. Parameter Description
6 Startup voltage lower
threshold of grid
connection (V)
According to the standards of certain countries and
regions, after the inverter is powered on for the rst 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.
7 Startup frequency upper
threshold of grid
connection (Hz)
According to the standards of certain countries and
regions, after the inverter is powered on for the rst 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.
8 Startup frequency lower
threshold of grid
connection (Hz)
According to the standards of certain countries and
regions, after the inverter is powered on for the rst 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.
9 Grid reconnection voltage
upper limit (V)
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.
10 Grid reconnection voltage
lower limit (V)
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 lower than Grid
reconnection voltage lower limit, the inverter is not
allowed to reconnect to the grid.
11 Grid reconnection frequency
upper limit (Hz)
The standards of certain countries and regions require
that after the inverter shuts down for protection due to a
fault, if the power grid frequency is higher than Grid
reconnection frequency upper limit, the inverter is not
allowed to reconnect to the grid.
12 Grid reconnection frequency
lower limit (Hz)
The standards of certain countries and regions require
that after the inverter shuts down for protection due to a
fault, if the power grid frequency is lower than Grid
reconnection frequency lower limit, the inverter is not
allowed to reconnect to the grid.
13 Reactive power
compensation (cosφ-P)
trigger voltage (%)
Species the voltage threshold for triggering reactive
power compensation based on the cosφ-P curve.
14 Reactive power
compensation (cosφ-P) exit
voltage (%)
Species the voltage threshold for exiting reactive power
compensation based on the cosφ-P curve.
