Description
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 SUN2000 shuts down.
The energy yield would be affected since it takes
too long for the power to resume and for the
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 concentration PV modules are used:
− If PV module type is set to CPV 1, the
SUN2000 can quickly restart in 60
minutes if the input power of PV modules
drops drastically due to shading.
− If PV module type is set to CPV 2, the
SUN2000 can quickly restart in 10
minutes if the input power of PV modules
drops drastically due to shading.
When the inverter sends reactive power at night,
an external PID compensation device (such as
the PID module) is required to perform PID
compensation for the system. In addition, this
parameter on the inverter needs to be set
correctly.
The inverter sends reactive power at night only
when it detects that the value of this parameter is
the same as the compensation direction of the
external PID compensation device.
 If no PID compensation device exists in the
system, set this parameter to Output
disabled.

If the system uses a PID compensation
device to increase the voltage of the PV- to
ground to a value greater than 0 V, set this
parameter to PV- positive offset.

If the system uses a PID compensation
device to reduce the voltage of PV+ to
ground to a value lower than 0 V, set this
parameter to PV+ negative offset.
