Huawei SUN2000-185KTL-INH0 User Manual

No. Parameter Description Remarks
14 Shutdown gradient
(%/s)
Species the power change speed
when the inverter shuts down.
-
15 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.
-
16 MBUS
communication
For inverters that support RS485
communication and MBUS
communication, you are advised
to set this parameter to Disable
to reduce power consumption.
-
17 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 rst. After
the PV power supply recovers
and the activation conditions
are met, the inverter
automatically activates the
upgrade.
18 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.
-
19 Duration for
determining short-
time grid
disconnection (ms)
The standards of certain countries
and regions require that the
inverter should not disconnect
from the power grid if the power
grid experiences a short-time
failure. After the fault is rectied,
the inverter output power needs
to be quickly restored.
