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 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.
NOTICE
Setting this parameter to Enable may cause power grid connection failure of the
solar inverters, which affects the energy yield.
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.
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.
If this parameter is set to Enable, the inverter shuts down after receiving
the OVGR signal. If this parameter is set to Disable, the inverter does not
shut down after receiving the OVGR signal.
Identifies the dry contact signals from the SmartLogger.
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 package is loaded first. After the PV power supply recovers and
the activation conditions are met, the inverter automatically activates the
upgrade.
If this parameter is set to Enable, the RS485-2 port can be used. If the port
is not used, you are advised to set this parameter to Disable to reduce
power consumption.
