Description
RCD refers to the residual current of the
SUN2000 to the ground. To ensure
device security and personal safety,
RCD should comply with the standard.
If an AC switch with a residual current
detection function is installed outside
the SUN2000, this function should be
enabled to reduce the residual current
generated during SUN2000 running,
thereby preventing the AC switch from
misoperations.
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 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.
 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.
