User Manual
No. Parameter
21 PV module type
22 PID compensation
direction
23 String connection
mode
Issue 02 (2022-06-30)
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 inverter
shuts down. The energy yield
would be affected since it takes
too long for the power to resume
and inverter 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 Built-in PID
compensation direction to the
actual compensation direction of
the PID module so that the
inverter can output reactive
power at night.
Specifies the connection mode of
PV strings.

Remarks
● If this parameter is set to
Crystalline silicon or Film,
the inverter 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 this parameter is set to
CPV 1, the inverter can
quickly restart in 60
minutes if the input
power of PV modules
drops drastically due to
shading.
– If this parameter is set to
CPV 2, the inverter can
quickly restart in 10
minutes if the input
power of PV modules
drops drastically due to
shading.
-
● When PV strings connect to
the inverter separately (All
PV strings separated), there
is no need to set this
parameter. The inverter can
automatically detect the
connection mode of the PV
strings.
● When PV strings connect to
one another in parallel
outside the inverter and
then connect to it
independently (All PV
strings connected), set this
parameter to All PV strings
connected.
