Description
In some specific application
scenarios, a power grid company
requires that the SUN2000 can
perform reactive power compensation
at night to ensure that the power
factor of the local power grid meets
requirements.
If this parameter is set to Enable,
when the inverter outputs reactive
power at night, it shuts down after
detecting that the PID compensation
is abnormal. If this parameter is set to
Disable, when the inverter outputs
reactive power at night, it does not
shut down when the PID
compensation is abnormal.
If Power quality optimization mode
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 modules. If the concentration PV
modules are shaded, the power drops
drastically to 0 and the SUN2000
shuts down. The energy yield would
be affected since it takes too long for
the power to resume and SUN2000 to
restart. The parameter does not need
to be set for crystalline silicon and
filmy PV modules.
When the external PID module
compensates the PID voltage for the
PV system, set PID compensation
direction to the actual compensation
direction of the PID module so that
the inverter can output reactive power
at night.

Remarks
This parameter is configurable only
when Isolation is set to Input
ungrounded, with a transformer.


If PV module type is set to
Crystalline silicon or Film, the
SUN2000 automatically detects
the power of PV modules when
they are shaded and shuts down
if the power is too low.
 When the concentration PV
modules are used:
− If PV module type is set to
CPV 1, the inverter can
quickly restart in 60 minutes
when the input power of PV
modules drops drastically
due to shading.
− If PV module type is set to
CPV 2, the inverter can
quickly restart in 10 minutes
when the input power of PV
modules drops drastically
due to shading.
