No. Parameter Description Remarks
3 RCD enhancement RCD refers to the residual current
of the inverter to the ground. To
ensure device and personal safety,
RCD should be limited to the
specied value in the standard. If
an AC switch with a residual
current detection function is
installed outside the inverter, this
function should be enabled to
reduce the residual current
generated when the inverter is
running, thereby preventing the
AC switch from misoperations.
-
4 Night-time
reactive power
output
In some specic application
scenarios, a power grid company
requires that the inverter can
perform reactive power
compensation at night to ensure
that the power factor of the local
power grid meets requirements.
This parameter is displayed
when Isolation settings is set
to Input ungrounded, with
TF.
5 PID protection at
night
When the inverter outputs
reactive power at night and this
parameter is set to Enable, the
inverter will shut down
automatically if it detects
abnormal status of the PID
compensation.
-
6 Power quality
optimization mode
If this parameter is set to Enable,
the inverter output current
harmonics will be optimized.
