Description
If this parameter is enabled, the
SUN2000 automatically starts after
communication recovers. If this
parameter is disabled, the SUN2000
needs to be started manually after
communication recovers.
Specifies the duration for
determining communication
interruption, and is used for
automatic shutdown for protection in
case of communication interruption.
Specifies the duration for the power
to gradually increase when the
SUN2000 starts.
The SUN2000 monitors PV strings at
night. If Hibernate at night is set to
Enable, the monitoring function of
the SUN2000 will hibernate at night,
reducing power consumption.
For SUN2000 models that support
both RS485 and MBUS
communication, when RS485
communication is used, you are
advised to set MBUS
communication to Disable to reduce
power consumption.
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.
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.

After the SUN2000 upgrade starts,
if Upgrade delay 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 PV strings are easily shaded, you
are advised to set String monitor
to Disable to prevent false alarms.
