Description
Upgrade delay 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 SUN2000 upgrade starts, if Hibernate
at night is set to Enable, the upgrade package is
loaded first. After the PV power supply recovers
and the activation conditions are met, the
SUN2000 automatically activates the upgrade.
If this parameter is set to Enable, the RS485-2
port can be used. If the port is not used, it is
recommended that this parameter be set to
Disable to reduce power consumption.
The SUN2000 monitors PV strings in real time.
If any PV string is abnormal (such as the PV
string is shaded or the energy yield decreases),
the SUN2000 generates an alarm to remind
maintenance personnel to maintain the PV string
in a timely manner.
If PV strings are easily shaded, you are advised
to set String monitor to Disable to prevent false
alarms.
Specifies the threshold for determining PV string
exception. The false alarms caused by fixed
shadow shading can be controlled by changing
this parameter.
This parameter is displayed when String
monitor is set to Enable.
Specifies the threshold for starting PV string
exception detection. The false alarms caused by
