Description
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.
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.
If this parameter is set to Enable,
the inverter output current
harmonics will be optimized.
This parameter is used to set
different types of PV modules and
the shutdown time of the
concentration PV module. If the
concentration PV modules are
shaded, the power drops
drastically to 0 and the inverter
shuts down. The energy yield
would be affected since it takes
too long for the power to resume
and inverter to restart. The
parameter does not need to be
set for crystalline silicon and filmy
PV modules.

This parameter is displayed
when Isolation settings is set
to Input ungrounded, with

● If this parameter is set to
Crystalline silicon or Film,
the inverter automatically
detects the power of PV
modules when they are
shaded and shuts down if
the power is too low.
● When concentration PV
modules are used:
– If this parameter is set to
CPV 1, the inverter can
quickly restart in 60
minutes if the input
power of PV modules
drops drastically due to
shading.
– If this parameter is set to
CPV 2, the inverter can
quickly restart in 10
minutes if the input
power of PV modules
drops drastically due to
shading.
