Parameter
Description
Remarks
String connection
mode
Specifies 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.
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 specified time (set by
Communication interruption
duration), the inverter will
automatically shut down.
Communication
interruption
duration (min)
Specifies the duration for determining
communication interruption. Used for
automatic shutdown for protection in case
of communication interruption.
-
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.
Soft start/boot
time (s)
Specifies the duration for the power to
gradually increase when the inverter starts.
-
Shutdown
gradient (%/s)
Specifies the power change speed when
the inverter shuts down.
-
AFCI
The North American standard requires that
the inverter should have DC arc detection
function.
-
AFCI detection
adaptive mode
Adjusts the sensitivity of arc detection.
This parameter is displayed only
when AFCI is set to Enable.
AFCI self-test
Send the AFCI self-check command
manually.
