Feature Parameters
Parameter
Description
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.
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.
