Description
Specifies the connection mode of PV
strings.
The standards of certain countries and
regions require that the SUN2000
must shut down after the
communication is interrupted for a
certain time.
If this parameter is enabled, the
SUN2000 automatically starts after
communication recovers. If this
parameter is disabled, the SUN2000
needs to be started manually after
communication recovers.
Specifies the duration for determining
communication interruption, and is
used for automatic shutdown for
protection in case of communication
interruption.
Specifies the duration for the power
to gradually increase when the
SUN2000 starts.
The SUN2000 monitors PV strings at
night. If Hibernate at night is set to
Enable, the monitoring function of
the SUN2000 will hibernate at night,
reducing power consumption.
For SUN2000 models that support
both RS485 and communication,
when RS485 communication is used,
you are advised to set MBUS
communication to Disable to reduce
power consumption.

7 Man-Machine Interactions
Remarks
 When 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 PV strings connect to one
another in parallel outside the
inverter and then connect to it
independently (fully parallel
connection), set this parameter
to All PV strings connected.
If Communication interrupt
shutdown is set to Enable and the
SUN2000 communication has been
interrupted for a specified time (set
by Communication interruption
duration), the SUN2000 will
automatically shut down.
This parameter is displayed when
Communication interrupt
shutdown is set to Enable.
