Description
Remarks
Current error
during the scan
(A)
To prevent inaccurate scanning caused by
sunlight change, the current change of PV
strings operating properly should be
monitored when the I-V curves of PV
strings are being scanned. When the
current exceeds the specified value, it is
determined that the sunlight changes. The
I-V curves should be scanned again.
-
OVGR associated
shutdown
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.
This parameter is displayed if
the Japanese grid code is
selected.
Dry contact
function
Identifies the dry contact signals from the
SmartLogger.
Set this parameter to OVGR for
OVGR signals, and set it to NC
for other signals. This parameter
is displayed if the Japanese grid
code is selected.
Commanded
shutdown hold
after power
recovery
The standards of certain countries and
regions require that if the inverter is shut
down after receiving a command and
powered on again after power recovers, it
should still be in commanded shutdown
state.
-
Night-time
hibernation
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.
-
MBUS
communication
For inverters that support RS485
communication and MBUS
communication, you are advised to set this
parameter to Disable to reduce power
consumption.
-
RS485-2
communication
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.
-
Delay upgrade
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.
