SUN2000.
Issue 07 (2021-07-08)
Description
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.
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.
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 rectified,
the inverter output power needs
to be quickly restored.

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.
