No. Parameter Description Remarks
8 Built-in PID
compensation
direction
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.
-
9 String connection
mode
Species the connection mode of
PV strings.
● 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.
10 Automatic OFF
due to
communication
interrupted
The standards of certain countries
and regions require that the
inverter must shut down after the
communication is interrupted for
a certain time.
If Automatic OFF due to
communication interrupted is
set to Enable and the inverter
communication is interrupted
for a specied time (set by
Communication interruption
duration), the inverter will
automatically shut down.
11 Automatic ON due
to communication
resumed
If this parameter is set to Enable,
the inverter automatically starts
after communication recovers. If
this parameter is set to Disable,
the inverter needs to be started
manually after communication
recovers.
This parameter is displayed
when Automatic OFF due to
communication interrupted is
set to Enable.
12 Communication
interruption
duration (min)
Species the duration for
determining communication
interruption. Used for automatic
shutdown for protection in case of
communication interruption.
-
13 Soft start/boot
time (s)
Species the duration for the
power to gradually increase when
the inverter starts.
