Upgrade delay
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

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.

String monitor
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.
