Description
Remarks
MPPT multi-peak
scanning
When the inverter is used in scenarios
where PV strings are greatly shaded, set
this parameter to Enable, and then the
inverter will perform MPPT scanning at
regular intervals to locate the maximum
power.
-
MPPT multi-peak
scan interval
(min)
Specifies the MPPT scanning interval.
This parameter is displayed
when MPPT multi-peak
scanning is set to Enable.
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 specified 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.
-
Night-time
reactive power
output
In some specific 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.
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.
-
Strong
adaptability
If the power grid short-circuit capacity or
PV plant installed capacity is less than 3,
the power grid quality will be affected if
the power grid impedance is too high,
which may cause the inverter to
malfunction. In this case, if the inverter is
required to work properly, set this
parameter to Enable.
-
Power quality
optimization
mode
If this parameter is set to Enable, the
inverter output current harmonics will be
optimized.
