Parameter Description Remarks
PV module type This parameter is used to set
dierent 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
aected
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
lmy 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.
PID compensation
direction
The PID eect may result in the
power attenuation of PV modules,
which is mainly caused by the DC
voltage between PV modules and the
ground. Enabling this setting lowers
the DC voltage between PV modules
and the ground by reducing the
impedance on the input side to the
ground.
This parameter is displayed only if
PV module type is set to
Crystalline silicon.
PID running mode Species the operation mode of the
SUN2000 built-in PID.
This parameter is displayed only for
the models that support Built-in
PID repair.
PID nighttime o-
grid repair
Species whether to enable the PID
nighttime o-grid repair.
This parameter is displayed only if
PID running mode is set to Repair.
PID daytime o-grid
repair
Species whether to enable the PID
daytime o-grid repair.
This parameter is displayed only if
PID running mode is set to Repair.
