Description
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.
The PID effect 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.
Specifies the operation mode of the
SUN2000 built-in PID.
Specifies whether to enable the PID
nighttime off-grid repair.
Specifies whether to enable the PID
daytime off-grid repair.
Specifies the connection mode of PV
strings.
 When the PV strings connect to the
inverter separately (fully separate
connection), there is no need to set this
parameter. The inverter can
automatically detect the connection
mode of the PV strings.
 When the PV strings connect to one
another in parallel outside the inverter
and then connect to the inverter
independently (fully parallel
connection), set this parameter to All
PV strings connected.

Remarks

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.
This parameter is displayed only if PV
module type is set to Crystalline
silicon.
This parameter is displayed only for the
models that support Built-in PID
repair.
This parameter is displayed only if PID
running mode is set to Repair.
This parameter is displayed only if PID
running mode is set to Repair.
