6.3.8.1 Running Parameters
Grid Parameters
Parameter
Description
Grid Code
Set this parameter based on the grid code of the country or region
where the inverter is used and the inverter application scenario.
Isolation settings
Set the working mode of the inverter based on the grounding
status at DC side and the connection to the power grid.
Output mode
Specifies whether the inverter output has a neutral wire based on
the application scenario.
V-phase grounded
The default value is Disable. Set this parameter to Enable when
the phase wire from the transformer to the inverter is grounded.
PQ mode
If this parameter is set to PQ mode 1, the maximum AC output
power equals the maximum apparent power. If this parameter is
set to PQ mode 2, the maximum AC output power equals the
rated output power.
Automatically start upon
grid recovery
Specifies whether to allow the inverter to automatically start after
the power grid recovers.
● Enable: The inverter automatically starts when the power grid
recovers from a fault or outage.
● Disable: The inverter does not automatically start when the
power grid recovers from a fault or outage. The inverter starts
only after a startup command is delivered.
Grid connected recovery
time from grid faults (s)
Specifies the time after which the inverter begins restarting after
the power grid recovers.
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.
