Description
The standards of certain countries
and regions require that the
inverter must shut down after the
communication is interrupted for
a certain time.
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.
Specifies the duration for
determining communication
interruption. Used for automatic
shutdown for protection in case of
communication interruption.
Specifies the duration for the
power to gradually increase when
the inverter starts.
Specifies the power change speed
when the inverter shuts down.
The inverter monitors PV strings
at night. If this parameter is set to
Enable, the monitoring function
of the inverter will hibernate at
night to reduce power
consumption.
For inverters that support RS485
communication and MBUS
communication, you are advised
to set this parameter to Disable
to reduce power consumption.
This parameter is mainly used in
the upgrade scenarios where the
PV power supply is disconnected
at night due to no sunlight or
unstable at dawn or dusk due to
poor sunlight.

After the inverter starts to
upgrade, if Delay upgrade is
set to Enable, the upgrade

and the activation conditions
are met, the inverter
automatically activates the
upgrade.
