Parameter Description
Output mode Species whether the inverter output has a neutral wire based on
the application scenario.
Automatically start upon grid
recovery
Species whether to allow the inverter to automatically start after
the power grid recovers.
Grid connected recovery time
from grid faults (s)
Species the time after which the inverter begins restarting after
the power grid recovers.
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.
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.
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.
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.
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.
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.
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.
Reactive power
compensation (cosφ-P)
trigger voltage (%)
Species the voltage threshold for triggering reactive power
compensation based on the cosφ-P curve.
Reactive power
compensation (cosφ-P) exit
voltage (%)
Species the voltage threshold for exiting reactive power
compensation based on the cosφ-P curve.
